Five Reasons Why to buy Scotty AI DC DC for Lithium Battery Charging from an Alternator.
12-24V DC DC 12-36V DC DC 12-48V DC DC 24-48V DC DC All bi-directional
Protects your Alternator
- Scotty AI DC DC uses the internal regulator of an alternator. Factory Supplied.
- Scotty AI DC DC does NOT modify or add to the alternator in any way.
- Scotty AI DC DC has an accurate temperature sensor that is placed on the alternator housing.
- When Scotty AI is running, the machine learning logs the alternator temperature operating range.
- AI monitors rate of change of temperature with current, time and voltage to identify out of range conditions.
- When out of range occurs, Scotty AI sets the mode back a level: Hard to Medium, Medium to Soft and Soft to Off.
Auto-tunes Alternator
No Programming Required
- Scotty AI DC DC does not need to know alternator or engine speed.
- The patented SCOTTY AI program maps the voltage and current with current rate of change to determine the optimal operating curve.
- The result is plug-n-play that your son or daughter can auto-tune from the Smartphone App.

Scotty AI is a bi-directional DC DC power converter with an AI driven controller that:
- Automatically extracts power from an alternator.
- Auto-tunes to match the specific alternator attached.
- When engine is off, reverses power direction.
- Does not require engine RPM to optimize its output.
The clever and novel AI function has an international provisional patent:
- During an initial “auto-tuning”, Scotty AI goes through 4 phases of machine learning. At a derived voltage, a range of power loads is applied to the alternator. Under each load, the voltage breaks from derived voltage. The “voltage break profile” including voltage rate of change is analysed. This process is then repeated 3 more times at different derived voltages to capture up to 90 data points. You see the process in the video.
- Using mathematical modelling, the data points are used to form a dynamic power curve without the requirement to measure RPM. In fact, although engine speed is a key input to produced alternator power, actual RPM measurement is really an irrelevant parameter in our AI derived power curve.
- During operation, slight changes to voltage are constantly applied under load and from the resulting voltage break profile, the load is increased or decreased to match the tuned model.
- The benefit of Scotty Ai over RPM derived control is that power output changes because of alternator temperature change and net power available if additional electrical loads are applied at the alternator voltage level, are automatically accommodated. It is clean and simple single auto-tuning process of 2 minutes.
- There are 3 profiles derived during the Auto-tuning process that are labelled: “Soft”, “Medium” or “Hard”. The user can select one of these in addition to “off” from the touch display on the helm station.
- In the video, you will see the power output at the “Medium” setting is very close to the power output at the “Hard” setting. Yet the actual current is some 20-30A less at the medium setting. Less current, less power losses and less heat.
- An additional AI function is machine learning on alternator temperature and power. We have found a very wide range of operating temperatures in the engine bay. Using measured temperature on part of the alternator alone as a dampening variable is an educated guess. Rate of change of temperature is a good proxy of how hard the alternator is working when at or close to its limit. This is what we measure and machine learn. Rate of temperature change, temperature, current and voltage are all analysed for a normal range for the alternator. If the temperature variables go outside of the norm, the setting level is pushed down from “hard” to “medium” or “medium” to “soft” reducing the current. This adds a layer of protection to the alternator and is a fundamental goal of Scotty AI.
- Once Scotty AI is auto-tuned, there is no need to apply this again. No Laptop nor external program is ever needed.
- The manual is 1 page supported by extensive self diagnostics in the smartphone app. Simple text messages are used. There is a glossary of terms and explanation in the app. Firmware can be updated “Over the Air” from a smartphone.
- Reported variables include cable power losses on the alternator side and the battery side if a CAN BMS. This can be valuable in maintenance assessments.
- The Smart Touch Display is supports Scotty AI and CAN-BMS batteries with battery monitoring, alternator power extraction and alternator temperature. It also allows for adjusting the power settings at idle.
- We highlight many different applications where Scotty AI solves problems for marine users as case studies. Click on the cards below to read each one.
Redundancy for the Marine User
- With Scotty AI, the native operating voltage of the engine’s starting battery and an attached house battery is preserved. This means that if the 24v, 36v or 48V battery that Scotty AI is charging ceases to function, the user can continue operating with the native voltage system.
- This redundancy is highlighted as an emergency operating mode during lightning conditions with the Privilege catamaran owner. He disables and isolates the 48V system: batteries and inverter charger during lightning conditions and motors on the native 12V system.
Simplified House Battery for Fishing Boats with trolling motors/geo-stationary anchors.
- Trolling motors/geo-stationary anchors operate at higher voltages. Without Scotty AI, a 24V or 36V battery is required plus the charging system. If 12V refrigeration and other loads are also present, then a second house battery with charging system is required. With Scotty AI only one battery system is required. Scotty AI can charge a 36V battery from either the alternator or from the shore power source. It will be tuned for the engine(s) but will accept the fixed shore power effortlessly.
- There is a choice of locating the house battery at the 36V level or the 12V level. If the 12V level is chosen, using a pre-charge function, Scotty AI can operate the 36V load without a 36V battery. If the 36V level is chosen, Scotty AI can deliver 1500W or 3000W at the 12V level for inverters as well as small loads like refrigeration. Watch the video on a 3000W inverter load being pulled through Scotty from a 36V battery bank.
- Generally fishing boats have limited space for multiple We highlight many different applications where Scotty AI solves problems for marine users as case studies. Click on the cards below to read each one.
Simplified House Battery for Fishing Boats with a Gyro.
- Gyros consume significant energy. There is also a delay if waiting to spin up the gyro on shore power. By using a 48V battery bank, gyro users get a higher energy density in a smaller volume. This can power the gyro all night. Scotty AI can charge this battery bank AFTER the power for the 12V gyro is consumed. This gives high replenishment energy if the outboard alternators have the power capacity. Watch the video of two Verado 275hp engines, a Scotty AI 3000 and a Seakeeper 1. Electric steering consumes a lot of power so in this case study, we upgraded one of the Verado alternators to 200A from 120A.
Catamarans with no genset or users not wanting to run a genset.
- This is one of the strongest applications for Scotty AI. Each alternator can be individually auto-tuned yet the pair operate on the one Can network with the battery BMS.
- A ‘floating master” is established between the two units. Should the user be motor sailing, switching from port to starboard and vice versa results in the floating master role switching seamlessly.
- The Scotty AI 1500 has a maximum current draw of 125A at 12V and is well matched with the engine alternators fitted as standard by most European catamaran manufacturers.
Large power yachts wanting a silent night.
- It is common to find the master cabin on 100ft motor yachts within earshot of operating gensets. The owners want a silent night… and early morning while the espresso and induction is running. The battery capacity required is significant and the only practical voltage is 48V. The refrigeration is generally at the 24V level to match the native starting system. Scotty Ai not only charges from the engine alternators at 24-48V but then discharges when the engines are off. The 24V loads are significant and Scotty Ai is typically delivering up to 3000W continuously on the 24V side over night.
- Scotty AI provides both a high replenishment capability with redundancy for larger vessels with 24V alternators at 150A each. Up to two of these per engine have been fitted giving a total 16kw capacity. With two Scotty AI’s per engine, give a total of 12kW charging capacity.
- Installed systems include a 100kWh 48V house bank being replenished from 12kW Scotty AI array which is sufficient to run the saloon and helm aircon loads and electronics power while motoring without the genset running. The resulting “silent night” is gold to the owners.
Auto-tunes to Load Changes
- When an alternator gets hot, its efficiency and output level changes. External Alternator regulators find this hard to control.
- Scotty AI DC DC auto-tunes to the changing load and changing efficiency of the alternator.
Maximum Power At Idle
Solar Backup
- When the solar yield is poor and you need maximum DC DC power at Idle, just dial up "HARD" on the optional Touch Display or the Smartphone App.
- Your alternator is protected by AI. Should the temperature goes out of bounds then the setting will be automatically adjust back to medium.
- You just sit back and relax.
Scotty AI is on VE.CAN
Charges to CAN BMS
- Scotty AI runs on the 250 baud VE.CAN port together with compatible lithium batteries.
- It charges to the Charge Current Limit Set by the BMS
- If no BMS, then it charges to Max Voltage set on Smartphone App and storps charge either when voltage is reached or the "Stop Charge" wire nput is activated or deactivated.
The Bi-directional difference: 48-12V DC DC in less than 25ms
Scotty AI is Bi-directional
Switches to supply 12V or 24V Loads
- Scotty AI will switch to supply 12V or 24V loads in 25ms.
- If there is a big winch or other 12V or 24V load, it will also switch even when the alternator is running. Simply turn "off" on the Smartphone App or Optional Touch Display. The full additional power is delivered to the starter battery in addition to the alternator power,
Scotty AI Meteor is Bi-Plug-n-play
12V - 24V or 36V or 48V Meteor Lithium
- Scotty Meteor AI will Plugs to front of Meteor train
- The CAN connection, Voltage and power bus connection are all internal.
- The Positive Plug that attaches to front of Scotty AI meteor has two Megafuses. One at 12V and the other at the Meteor Battery Power Supply.
SCOTTY AI for SILENT NIGHTS
Privilege 51.5 owners wanted Silent Nights on the water. They also wanted to run “Zero Genset” and installed 3.2kW solar. The 12V DC loads are around 600W+ without winches/windless. A 48V 20kWh Lithium bank was installed as an energy overlay.
As a backup to solar two Scotty AI’s provide both a high replenishment capability and redundancy. When Scotty’s are off, the 12V alternators will continue to charge the existing 12V house battery.
With significant 12V loads, the available power to Scotty AI varies widely. Scotty AI’s patent pending auto-tuning maximizes the charging power prioritizing the 12V loads.
Should one alternator fail for some reason, the Scotty AI associated ceases operation automatically and the floating master role switches if required
The Smart Touch Display allows the skipper to set the alternator engine load to Soft, Medium or Hard depending whether motor sailing or solar back up power without running the Genset.

SCOTTY AI in NEW CATAMARAN
For new-built catamarans in the 36-46ft size, the factory fitted 12V lithium house battery bank stays as installed and Scotty AI and a large capacity additional house bank at either 24V or 48V is an overlay energy system.
When running the engines, Scotty AI is auto-tuned with the “lithium house” enabled. The patent-pending auto-tuning is done on either engine independently. Scotty AI is then ready to run.
With either or both engines running, Scotty Ai waits till the house battery is significantly charged at 90%+ before cutting in and extracting power up to 3000W per engine. (the factory fitted engines on popular brands have 120A capacity at 14.4V and the 1500W Scotty AI model is a perfect fit)
When the engines are off, Scotty AI delivers DC power back to the factory fitted 12V house bank to keep it always in the circa 90% band.

SCOTTY AI with 36V in FISHING BOATS
Fishing boats with GPS-guided propulsion/autopilot packages and/or virtual anchor systems using high torque 36V motors have two options that significantly simplify a single house battery bank design:
- Scotty AI can simply provide the 24V or 36V load (generally up to 1500W is sufficient) on demand without the need for a 36V house battery. This can be from a single 12v house battery design.
- Scotty AI can simply charge a 24v or 36V Auxiliary battery and use the bi-directional feature to supply the 12V loads without the need for a 12V house battery.
- High loads, including up to a 3000W inverter can be used on the 12V side pulling power through Scotty AI from the 36V Auxiliary battery.
- The result is a simplified single auxiliary battery system.
SCOTTY AI in FISHING BOATS & GYRO
For outboard engines, the features above allow the engine to idle with little or no net output, then ramp up the power to a full 3000W at cruising RPM (provided the outboards have alternator capacity). This unique and innovative product allows fishing boats to run gyro’s and other high demanding loads with a battery bank being charged at the same time the gyro is running.
- The vessel can leave the dock immediately if the gyro application is for a “restful night” at anchor later in the day.
- Scotty AI allows the gyro power demand to have priority at any engine RPM
- Once the gyro demand has reduced after spin up, Scotty AI will extract power for the auxiliary battery if required.
- Once at anchor, Scotty AI will direct power from the auxiliary battery bank back to the gyro as it is fully bi-directional DC DC.
- Scotty AI can direct up to 3,000W to the gyro and any other 12V (or 24V) loads.

SCOTTY AI in LARGER YACHTS
Scotty AI provides both a high replenishment capability with redundancy with 24V alternators at 150A each. Up to two of these per engine have been fitted giving 16kw capacity. Two Scotty AI’s per engine can charge at 12kW.
An 48V Lithium bank is installed as an energy overlay. The existing 24V AGM house bank is preserved.
Scotty AI is auto-tuned per alternator. When all Scotty AI units are activated a patent pending ‘floating master” is established between.
Should one alternator fail for some reason, the Scotty AI associated ceases operation automatically and the floating master role switches if required
If the Scotty AI’s are charging the 48V auxiliary battery and this operation is stopped, the vessel can continue to run on the 24V AGM house bank.
Installed systems include a 100kWh 48V house bank being replenished from 12kW Scotty AI array which is sufficient to run the saloon and helm aircon loads and electronics power while motoring NO Genset. “Silent Nights”
Scotty AI is alternator charging using a revolutionary DC DC. It is "Automotive Grade" placing the reliability and ruggedness above commercial grade "Victron" products.
Now in version 2, we have added AI. This is the result of over 300 installs of "manual tuning" in a wide variety of marine and RV applications. This is so revolutionary as it does not require the vehicle RPM to determine the alternator output. It determines it through AI which is patent pending.
- Auto-tunes to the power curve of the alternator. It does this an a mandatory 2 minute startup process the first time you use Scotty AI. After that, it is auto-tuned.
- When the alternator temperature rises or other loads are applied at the vehicle, Scotty adjusts the tuning automatically for this alternator.
- Layered on top of this are three "idle settings" as well as "off". Soft, Medium and Hard have 3 different power demand results on the alternator both at idle and when driving.
- It shows the cable losses in watts for the alternator to Scotty AI cable and Scotty AI to Lithium battery with CAN BMS.
- The firmware can be updated "OTA" Over-the-Air from your smartphone, tablet or laptop.
Meet Michael Nielsen. Michael upgraded from a Scotty Ver 1 to Scotty AI for his LC79. There is not much we can add to Michael’s testimonial so we will let you list to it first hand.
Scotty gives simplicity as there is no need for a 12V house or auxilliary battery. It is 100% bi-directional.
Scotty looks after your alternator with a dedicated alternator temperature sensor. There are 3 power settings at "idle". "Soft", "Medium" or "Hard".
