LiFT Pack X-Series

For: Counterbalanced Electric Forklifts
Longer battery run time

Run Time

Fast charging


Lower cost


Experience More Power On A Single Charge With Lithium-ion Technology

No water maintenance

No More Water Maintenance

Simplify your operations by no longer needing to manage watering schedules for your batteries. This is not only a huge time saver, but allows operators to focus on moving product rather than maintaining battery maintenance schedules.

Lithium-ion cells

Longer Lasting

The flat discharge curve and high sustained voltage mean forklifts run faster on each charge, without getting sluggish. The overall battery life lasts 2x than that of lead-acid alternatives, thus providing significant financial savings.

Modular blade design

Modular Blade Design

The LiFT Pack X-Series is a modular system utilizing up to four blades, each blade containing 7kWh of power. Up to four blades can be installed in the battery box, making customization and maintenance easy.


Fast Charge On Demand

All you need is one battery per truck, even with 2- or 3-shift operations! No more battery rooms. No ventilation needed while charging. Quick opportunity charge means your crew can simply plug in the equipment during breaks, then get back to work.

Experience the Difference

Learn why customers choose to run their forklifts using lithium-ion from Flux Power.




Customers experience run time increases of up to 45% over similarly rated (amp-hour) lead-acid batteries. 

Flux Power LiFT Packs get an amazing 2000 cycles at 80% depth of discharge, meaning these batteries outlast alternatives in every way. 


Environmentally Friendly

Lithium-ion batteries contain no toxic lead or acid and don't release explosive gases when charging. Say goodbye to noxious fumes with a clean system built for the modern working environment. 

Lower your energy costs. Testing has shown Flux LiFT Packs consume 30% less energy when moving 200 pallets weighing 2,500 pounds each, thus reducing your electric bill and conserving energy as well as reducing overall operations costs.
