WHY
Where we start
We build the pack around your device, not around a cell we happen to stock. Send the enclosure dimensions, the current profile, and the protocol your device speaks — cell choice, layout, harness and thermal all follow from there.
Every build includes a BMS configured for your load, a fuel gauge calibrated on the same cell that ships in your pack, and a protocol document your firmware team can code against.

From enquiry to production in five steps
01
Enquiry & feasibility
An engineer reads your drawing and replies with a feasibility note and the cost drivers we can already see.
02
Quote with DFM
Priced off our own cost model, not a supplier's quote. DFM feedback included — what to change, and what it saves.
03
Prototype
BOM locked against your target certifications, then first units built. The protocol document ships with the samples.
04
Validation
You test in your device. We run gauge calibration, cycle and temperature verification, and send you the report.
05
Production
Pilot run first, then series production. Every pack is capacity-graded and aged before it ships — whatever the order size.

Four reasons
customers stay
Every pack is tested, not every batch
Cells capacity-graded and matched before assembly. Finished
packs aged and tested before release — whatever the order size.
Ask what a change costs and you'll get a number
Pricing is built here, from the BOM up. Swap a connector, add a
thermistor, drop a series — the answer comes back in the same
conversation, not the next quote cycle.
Technical questions reach an engineer.
Ask about series count, gauge behaviour or protocol timing and
the reply comes from the person who'd design it, not from
someone who has to go find out.
Twenty years of battery engineering, our own
factory since 2017.
Across 2,000+ programs we've seen most of the ways a pack can
go wrong — usually before it goes wrong on your bench.
