Overview:
Thumper Lithium LiFePO4 batteries are fully sealed and are designed to be mounted on any angle for easy application.
Equipped with an internal battery management system (BMS), the Thumper Lithium offers safe charging and discharging with over temperature protection, under and over voltage cut off protection and also internal short circuit protection.
The LiFePO4 range of batteries are less than half the weight of a traditional AGM battery, whilst still offering all of the benefits of a heavy duty deep cycle.
These batteries are designed to hold the terminal voltage higher throughout each cycle, resulting in an increase depth of discharge and a longer overall run time with heavier draw appliances.
