A 48V-class LiFePO4 battery for a military unmanned ground vehicle
At a glance
- Customer

- Relationship
- repeat orders from 2020 through 2025
The challenge
The program needed an unmanned ground vehicle that could carry its full payload. The existing lead-acid / AGM batteries were heavy, and battery weight counted directly against what the vehicle could carry.
What LBC supplied
LBC supplied a 48V-class lithium iron phosphate (LiFePO4) battery pack with a battery management system, sized as a lighter replacement for the lead-acid / AGM batteries.
The result
The LiFePO4 pack was lighter than the lead-acid / AGM batteries it replaced, which helped the vehicle meet its payload targets. The program came back for repeat paid orders, through the prime contractor and its integrator, from 2020 through 2025. In 2026 the program moved into field sustainment.
What this means for your program
If battery weight limits your vehicle's payload or range, the chemistry and pack architecture matter as much as the cells. Send the voltage window, peak current, envelope and weight budget and LBC will propose a pack. See defense battery packs and 48V LiFePO4 battery packs.
