Don’t let extreme weather steal your thunder
The 24-100XTREME uses low temperature cylindrical cells with the widest usable temperature range of any LiFePO4 battery on the market. It also provides an exceptional amount of power for its size, delivering a continuous charge/discharge rate of 200A. We used the same high power BMS as the 12V model but because the 24-100XTREME outputs at 25.6V, this battery allows you to draw up to 5120W in continuous power.
The upgraded BMS passively balances all internal cells, and also supports installation of up to four 24-100XTREME batteries in parallel (and/or two in series) with auto balancing for parallel connected batteries. It provides a complete range of protections including surge currents from a large inverter or motor.
Come rain or shine Never stop exploring
Whatever the weather, you can count on Roamer to keep every moment fully charged with adventure. Our XTREME batteries can be charged at temperatures between minus 30 and 60, and discharged between minus 40 and 60 - enabling limitless possibilities when off-grid. While many batteries are notoriously problematic in cold temperatures, ours perform excellently - thanks to our innovative BMS offering low temperature charge protection.
