Custom Lithium Packs for Ming Trucks/Locomotives

Our robust mining-truck lithium battery pack is designed for demanding underground applications. Truck and locos that are powered by our lithium battery have zero emissions, which leads to savings on maintenance, ventilation and cooling, it provides a powerful opportunity to lessen the environmental footprint and create a healthier work environment for miners.

Built to Last

Constructed with Frey's high-power output cell, it's extremely durable and long-lasting, with a cycle life of ≥3,000 times at 80% depth of discharge.

High Capacity and Productivity

Thanks to the high capacity, high-power lithium battery pack, battery-driven trucks move highly efficient, hauling material faster than their lead-acid driven counterpart.

Extremely Safe

All Frey’s custom lithium pack for mining are explosion-proof, the cells are Mining Safety MA® certified

Healthier Working Environment

Zero-emissions helps to create a healthier work environment and lessens the environmental footprint.

Lower Costs

Zero-emissions means your need for underground ventilation and cooling is minimized, no more frequent lead-acid battery replacement, no backup battery is required
