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.

Here at Roamer, we take safety extremely seriously and strive to make the safest LiFePO4 batteries possible. It is no secret that Lithium can be dangerous and whilst LiFePo4 is without doubt, the safest option, it is still not without risk. And that’s why we go above and beyond on both compulsory and voluntary extensive safety tests and processes. We choose to test every single battery before it leaves the factory by cycling to 100% and 0% and applying a high charge and discharge load to identify potentially faulty cells and connections, test BMS performance and verify cell balance at the top and bottom of the voltage-charge cycle. Our SMART3 batteries use only traceable branded cells from reputable manufacturers with lab test reports to verify battery safety as part of the EN 61619 certification. Finally, our product and fulfilment services also meet the courier requirements to ship Dangerous Goods under the UN3480 certification.
