We are an Australian company designing & building power conversion, energy and wireless digital switching devices. We tackle the really hard stuff that others just can’t do, for the mobile lifestyle.
Compact Power Packs
Cutting-edge packs that connect to the wall behind the fridge or can be retrofitted under a seat or in a tunnel boot. Your choice.
Advanced Digital Switching
Control from 7in touch screen, wireless or waterproof rubberised switches engraveable then add Carplay or Android Auto.
Compact Battery Packages
Lithium or Sodium batteries that plug together or stack vertically. Either way the compact size is designed to fit caravans.
Biggest Alternator Charging
250A DC DC charging with 100% protection of the alternator. Add the hybrid high power to vehicles of USA origin with a second mount for an additional 5-8kW of power.
Space is a luxury.
Your caravan will be a masterpiece of design.Â
Wherever you go, you want to enjoy this hard-earned luxury to the fullest.
When you want all night aircon plus all electric kitchen and instant hot water… you need replenishment energy. Thats what we deliver. There is nothing in the market that can deliver up to the 11kW of power from a second hybrid alternator and Scotty AI combo.
In VW Crafters and other vans, charge at up to 3.000W from the usually installed 250A 12V factory alternator..
This is THE Ultimate in Lithium batteries because of it’s incredible safety and long cycle life of 10,000 cycles.
Safiery have fitted the same Victron and Marine compliant BMS that has been used in the Meteor battery range that shows min/max cell voltages and temperature.

The traditional liquid lithium battery is called a ‘rocking chair battery’ by the scientific community because of its charging and discharging principle. The two ends of the rocking chair are the positive and negative poles of the battery, and the middle is the liquid electrolyte. Lithium electrons move back and forth across the two ends of the rocking chair and complete the charge and discharge of the battery during the process. In this process, there are many safety hazards: if there is overcharging, the battery is prone to heat, causing the electrolyte to swell, decompose, spontaneously ignite or even explode. The charging and discharging principle of a solid-state battery is the same as that of a liquid battery. The only difference is that its electrolyte is solid, which has many advantages over liquid electrolytes:
1) Higher Safety: The liquid electrolyte in traditional batteries creates safety hazards if over charging or electrical abuse. The result is thermal runaway and fire. Solid-state batteries have higher safety without this electroyte mass.
2) Higher Cycle Life: Because solid-state batteries use solid electrolytes, the cycle life is doubled. A minimum of 10,000 cycles at 80% depth of discharge is expected.
3) High energy density: As solid-state batteries use solid electrolytes, they do not need to use lithium-intercalated graphite anodes, but directly use metal lithium as the anode, which can reduce the amount of anode materials and increase the energy density of the entire battery.
4) Smaller size: The separator and electrolyte in the traditional liquid lithium battery account for nearly 25% of the entire battery mass. With the solid electrolyte, the distance between the positive and negative electrodes can be shortened to ten micrometers. The result is smaller battery dimensions and better quality control.
5) Lower temperature Range: Solid State Lithium is less affected by freezing temperatures because of the solid layers.
6) High Discharge rate:Solid State Batteries can discharge up to 10C. However, the BMS current rating limits discharge rates to 1C Continuous and 2C for 10 secs.
SAFETY SPECIFICATION
Meteor and Solid State share the same Safiery BMS that is our own design. This BMS displays the details of all the batteries connected to a Victron GX display. Read below why our BMS is so special!
After 100’s of lithium systems with a variety of BMS’s, we determined the shortfalls in nearly all of them when there is an extreme scenario. We then designed our own BMS and used it first up in Meteor battery range. It has been a huge success. Here are the design points that make it quite different:
Current sense is less than 0.1A at 48V.
When you put a large bank of batteries together, low loads are shared between the batteries. If the current sense resolution in each battery is say 0.5A, then 10 batteries in an array wont measure outgoing power till 5A at 48V is reached. The quiescent DC power for most Victron Systems is around 12W with modem and screen connected. The standard BMS will fail to read this. The Safiery BMS will read it down to 0.1A per battery.
BMS Cut Off voltage is just below 0% SOC
On the surface, this seems quite sensible. If the BMS doesnt turn off, it will continue to drain the battery. However, if it does turn off, then recovering a flat battery safely with BMS fully functional is so important. Otherwise batteries have to be disassembled and cells charged independently.
The Safiery BMS turns off around 8VDC. Ina typical 48V battery there is around 2-3 weeks before this will fully drain the battery. However, when the customer becomes aware of the flat battery bank, Scotty AI or an AC charger can recover the bank safely to 100% health. This small change eleiminates the majority of calls for “help” from owners without it.
Stop charge a Marine Regulatory requirement that has a problem with Victron Compliant BMS unless they follow this exact guideline from Victron
Victron compliant BMS guidlines call for just 3 parameters to share on the CAN BMS. Charge Voltage Limit, Charge Current Limit and Discharge Current Limit.
Most (nearly all) the BMS’s we have used in the past send a zero value for the charge current limit to “Stop Charge”. The problem is Victron does not always respond promptly to this command. The Victron External BMS commands respond immediately to voltage though. We had a horrific experience with this when a high power solar bank continued to charge the 48V batteries for 15 minutes after the BMS had issued a zero Charge Current Limit. That was on a catamaran. Lesson learned.
Safiery’s BMS sends a zero Charge Current Limit to Victron some 3-5 mins before the battery relay may open. Then 1 minute before the battery relay may open it reduces the Charge Voltage Limit and Victron responds perfectly. The timing to reopen is internal information. It has taken more that 5 firmware revisions when testing to perfect this.
In the next accordion block is an on-line review of a customer who went away (to Bali) for 2-3 weeks with the system on and no solar charging as the vehicle was moved to the garage.
Watch to see what happens. This is truly the best example to give confidence to customers to manage their sysems by them self, an absolute essential in marine.
Our process is very simple.

Digital Switching 7in Touch Screen Inverter Charger and Solid State Lithium
Tank measurement can be so troublesome. If you have a jack-off canopy, then even more so. This is why we developed a bluetooth battery operated radar tank level sensor.
It communicates directly with Victron Cerbo or if you dont have a Victron System then see it on the STAR-Touch 7 inch Display when you combin with STAR-Power.
Customers wanted a digital switching system that is so easyto install. Some wanted to operate only with switches, others touch screens and then others to use a phone app. Safiery have all these forms of control plus Carplay and Android auto. The simplicity is that all these communication paths go directly to the STASHIP controller. This reduces the cost to make STASHIP around half the cost per output to the published retail price of Redarc equialent.
