Power Tower 3.9 Battery


Not only do the Power Tower batteries pair perfectly with the Power Tower, but they can also be used with any pre-existing 48 VDC system.

Featuring locking casters, folding handles and mounting tabs, the batteries can be placed wherever best.

Built-in screen that displays battery voltage, power consumption, amperage and time left until fully charged or fully discharged.

LiFePO4 batteries ensures a safe and long-lasting energy storage system that weighs 3 times less and takes up 3 times less space than lead acid batteries. These batteries also protect themselves from over discharge and over charge scenarios and feature a lifespan over 3000 cycles.

This battery chemistry is used across all the HPS products and has a proven track record in some of the harshest environments including mining and transit.
