Every cloud has a silver lining
The 100XTREME uses our exclusive low temperature cylindrical LiFePO4 cells with the widest usable temperature range of any LiFePO4 battery on the market. And because this powerhouse can be charged down to minus 30 and discharged down to minus 40, there’s absolutely no need for cell heaters.
This battery provides an exceptional amount of power for its size - delivering a continuous charge/discharge rate of 200A. That’s twice the power of most of our competitors and enough to run an inverter up to 2600W. The state-of-the-art cells also ensure stable voltage throughout the charge and discharge curve with a long lifespan of up to 3500 cycles, at 80% depth of discharge.
Come rain or shine Never stop exploring
Our XTREME batteries are expertly designed to withstand the coldest temperatures and harshest environments. Traditional LiFePO4 batteries cannot be charged below zero but the Roamer XTREME uses exclusive low temperature cells which can be fast charged without needing a heater. Whatever the weather, you can count on Roamer to keep every moment fully charged with adventure.
