Your blueprint for adventure

Our 4th generation SMART batteries are in a league of their own - expertly designed to fuel and sustain the ultimate off-grid lifestyle. 

Grade A+ LiFePO4

Matched and traceable grade A LiFePO4 cells with steel compression brackets and double-bolted busbars. Only the best cells go into a Roamer battery.

Advanced BMS

Our new 300A BMS features voltage, temperature, short circuit, and overcurrent protection, plus active cell balancing, all monitored via Bluetooth and CANbus.

Engineered for power

Consistent high power requires more than the BMS; steel brackets, M10 terminals, and flexi copper busbars ensure durability and stability under heavy loads.

Serviceable and modular

Waterproof screw cases and modular construction allow easy disassembly for servicing, repairs, upgrades, and recycling. You can even fix on the go.

Communication ports

Easy monitoring via the Roamer SMART app, while RS485 and CANbus ports enable firmware updates and connection to other batteries and Victron GX devices.

Surge protection

Every Roamer battery now includes a precharge resistor to protect your BMS from the surge currents that can occur when connecting a high power inverter.

Bluetooth-enabled Roamer SMART App - Battery Management. Simple

The new Roamer Battery Management System (BMS) and Roamer SMART Bluetooth app build on all of our experiences to date and add several highly-requested features from our customers.

With a full suite of protections including low temperature charging and a pre-charge resistor to prevent inverter surge currents, this is our most resilient and powerful BMS to date. We’ve also extended the Bluetooth range, tightened security, and added a sleep mode for power conservation and an emergency mode that allows you to override BMS protections temporarily.

IMPORTANT!!  Installation of any LiFePO4 lithium battery is possible in most motorhomes, campervans and boats that use lead-acid leisure / auxiliary batteries. However, if the battery is to work efficiently and safely for its estimated lifetime, it's essential that it is installed correctly. This means that the charging voltages of the alternator, the mains charger and a solar panel - if fitted - are appropriate for the battery. If they are not, the battery can be quickly damaged.

If the vehicle is fitted with a "smart alternator", it will be necessary to fit a suitable battery to battery (DC-DC) charger as well.
