UniMAX®

POWERFUL. PROVEN. TRUSTED.

The UniMAX® is the ideal fast charger for forklifts, reach trucks and pallet jacks, charging a battery at up to 640 amps. Operators simply plug in and take their scheduled break. The UniMAX does the rest:

  • Reads the battery’s status, including size, voltage, temperature and state-of-charge.
  • Automatically optimizes an output profile.
  • Delivers the perfect charge.

The UniMAX puts you in control of your fleet with the ability to program automatic equalizations and wirelessly upload charger
event data.

And with up to 30kW of power, the UniMAX eliminates the need to change
batteries, even for the toughest 24/7 operations.
