Lightweight 12.8V 6Ah LiFePO4 replacement battery with integrated BMS, IP65 housing, 20A continuous discharge, and 5-year warranty
The Powerhouse 12V 6Ah LiFePO4 Lithium Battery is a modern replacement for similarly sized sealed lead-acid (SLA) batteries, offering significantly reduced weight, longer service life, and greater usable capacity per charge cycle.
Weighing just 0.7kg, this LiFePO4 battery is less than half the weight of many comparable SLA batteries. Its lithium iron phosphate chemistry maintains a higher operating voltage throughout the discharge cycle, providing longer usable runtime while also offering excellent charge retention during storage.
An integrated Battery Management System (BMS) provides protection against short circuits, excessive temperature, over-voltage, and under-voltage conditions. The battery can also be configured in series or parallel for applications requiring increased voltage or capacity.
