Design the pack around your OEM equipment

Custom lithium battery pack design starts with the equipment voltage window, load profile, required runtime, charger and mechanical envelope. LBC supports LFP and NMC pack design, BMS integration and custom manufacturing for qualified OEM volume programs.

Catalog voltage and capacity examples

These existing catalog designs are examples for an engineering review, not an application approval. Nominal voltage may differ from the equipment voltage class.

Review AGV/AMR requirements, UAV battery design, telecom backup and commercial energy storage. Compare 24V-class packs and 48V-class packs.

OEM battery pack FAQ

What are the minimum order quantities?

Catalog programs start at 10 units. Custom battery pack design and manufacturing programs start at 25 units.

What should an OEM battery pack inquiry include?

Include the equipment application, operating voltage, continuous and peak load, runtime or capacity, charger, available space, BMS communications, first-order quantity and annual volume.

Does a reference pack confirm application compatibility?

A reference design is a starting point. LBC reviews electrical, charging, mechanical, environmental and validation requirements before confirming a program specification.
