Battery Lithium Phaesun Sun Save 12-310 H Underseat

The Phaesun Sun Save series comprises LiFePO₄ batteries that have been specially developed for campers and flat installation under the passenger seat. They replace conventional lead, gel, or AGM batteries quickly and easily. Thanks to their high energy density, they offer maximum capacity at low weight and, due to their high efficiency, often allow for a smaller nominal capacity compared to lead-acid systems. The integrated battery management system provides reliable protection against overload, deep discharge, and temperature deviations. Bluetooth-ready models allow you to monitor cell voltages, temperatures, and alarm messages via the Sun Save app and are also equipped with an integrated heater for safe operation at low temperatures. The series thus combines efficiency, flexibility, and modern monitoring for mobile and stationary off-grid systems.
