Battery building

Packs built to order

We build packs around your Onewheel and your riding style: cell choice, pack shape, BMS and fusing all decided together. Every pack is spot welded, fused per group, tested for fit and logged with its own capacity test before it ships.

Three packs on the bench

Two built to order and one brought back from a fault, each started as a conversation about how the board gets ridden.

Insane pint torque

The brief. A Pint rebuild needed more range and more push up short climbs, without adding bulk to a lightweight board.

What we built. A 15S1P pack on Molicel P50S cells: high-capacity cells, to make the most of the limited space. Single-parallel layout keeps the pack small.

Result. Torque well beyond what the board came with, and no sag on the climbs that used to push it. Range pushed up to where the rider needed it.

Commuter battery pack, cells exposed

Commuter pack rebuilt around a tired original

The brief. A five-year-old board losing range on a daily commute and struggling up the hills. Range was the priority, without breaking the bank.

What we built. A slimline 15S3P pack on P30B cells reusing the stock battery box, Balance leads carefully planned and routed to avoid any crossovers and keep the thickness manageable.

Result. Range way past what the board did new, and a pack that will last for years to come. The board is back in service and feels like a massive upgrade.

Broken balance lead on a Chi pack

The brief. A Chi Battery pack that would not report cell voltages properly. The board was refusing to charge past a point and the rider did not want to have to replace a healthy pack over one wire.

What we did. Tested each cell group and located the bad wire. Stripped the pack down far enough to inspect the balance loom, traced the fault to a broken solder joint, resoldered the joint, tested and resealed the pack.

Result. All groups reporting again and charging normally. The pack went back in the board rather than in the bin.

How a build runs

1

Conversation

Board, budget, riding style, range you want and weight you will tolerate. We say what is realistic.

2

Spec

Cell choice, series and parallel count, BMS and fusing, plus any printed trays or caps needed to tidy up the build.

3

Build

Cell layout planned, glued and spot welded, balance wires neatly routed and terminated, pack wrapped and fitted in the chassis.

4

Test and log

Visual inspection, capacity and drain test recorded, results handed over with the pack.

Tell us about the pack you want

Every pack is quoted after a conversation: cells, range, splits, BMS, fitment and lead time all move the number. Send us the board, let us know how you ride it and what range you're after and we'll do the rest.
