Meet the Roamer 320SMART4 – our 4th generation 320Ah LiFePO4 battery for off-grid vehicles with high energy demands. The integrated Battery Management System (BMS) with Bluetooth provides remote monitoring via the Roamer BMS app and a market-leading discharge rate of 300A (450A peak) lets you run any domestic appliance up to 3600W via an inverter.
Our premium LiFePO4 cells provide an exceptional amount of power for their size, delivering a continuous charge/discharge rate of 300A. The state-of-the-art cells also ensure stable voltage throughout the charge and discharge curve and a long lifespan of up to 3500 cycles at 80% depth of discharge.
The upgraded BMS will actively balance all internal cells and supports installation of up to sixteen 320SMART4 batteries in series or parallel – with auto balancing for parallel connected batteries. It provides a complete range of protections including low temperature charging.
The Roamer 320SMART4 uses the highest quality Grade A+ matched cells and comes assembled with precision-engineered brackets, laser-welded cell connections, flexible copper busbars and an IP65 waterproof case.
Maintaining excellent balance throughout its 15 year life expectancy, your Roamer will deliver stable, high power with every cycle. Our additional factory and warehouse testing processes ensure the highest possible quality and because we believe in our product, we back everything with a 10 year warranty.
To ensure maximum lifespan, every 320SMART4 comes with a state-of-the-art internal Battery Management System (BMS) with Active Balancing – developed specifically for Roamer to support high power off-grid living.
