Expert Lithium Battery Repacks

Bring your tired battery pack back to full capacity. Project Lithium rebuilds and re-cells lithium Ion battery packs — tested, certified, and backed by warranty.

What is a battery repack?

A repack replaces the worn-out cells inside your existing battery enclosure with fresh, high-grade lithium cells — restoring runtime and range without the cost of a brand-new pack. We retain your housing, connectors and (where suitable) your BMS, rebuild the cell array to spec, and fully test before it leaves the bench. Ideal for e-bikes, e-scooters, e-skateboards, mobility, and custom builds.

Why choose Project Lithium

Warranty Backed

Every repack is covered by our workmanship and capacity warranty for total peace of mind.

Certified Technicians

Packs are built and signed off by trained battery technicians to strict safety standards.

Premium Cells

We use only genuine, high-grade A-cells matched and balanced for maximum life and capacity.

Fast Turnaround*

Most repacks are completed and tested within days, not weeks — get back up and running sooner.

How it works

Four simple steps from drop-off to a like-new pack.

1. Assess

Send us your pack or details. We test capacity, inspect the cells, BMS and housing, and quote the work.

2. Dismantle

We carefully open the enclosure, remove the spent cell array and salvage reusable components.

3. Rebuild

Fresh, matched cells are spot-welded to spec, fitted with a healthy BMS and sealed back into your housing.

4. Test & Return

Full charge, discharge and safety testing, then your restored pack is shipped back ready to use.
