The UltimatronYX Smart BMS12.8V 280AH LiFePO4 battery is designed for solar systems with a nominal voltage of 12V. It includes an integrated battery management BMS to control charging and provide information via bluetooth. An ideal replacement for lead-acid batteries with a much longer service life (up to 5000 cycles.)
Includes heating.
