OEM & ODM Battery Manufacturing
What we customize
Every dimension of the pack is on the table. Send a load profile or a mechanical drawing — we return a design with test data and a certification path.
Cell & chemistry
Prismatic / cylindrical LiFePO4, sodium-ion; grade and match per batch.
Voltage & capacity
12V to 1000V+; Ah sized to your envelope and duty.
BMS & comms
4S–16S+ smart BMS, CAN / RS485 / Bluetooth, firmware in-house.
Enclosure & thermal
IP65, wall / rack / cabinet / container, air or liquid cooled.
How a custom program runs
1 · Discovery
Load profile, envelope, certification target and volume.
2 · Design
Schematic, BMS logic and mechanical — NDA-protected.
3 · Prototype
Build, test and iterate; prototype equals production.
4 · Certification
UN38.3, IEC 62619, UL 1973 / 9540A, CE per market.
5 · Production
Neutral or your label, with per-unit test data.
OEM vs private label
OEM — we build to your drawings and label under your brand. Private label — we take a proven EGbatt design and put your name on it. Both keep the lithium expertise in-house: cell grading, pack assembly, BMS firmware and test under one quality system, with documentation in your name.
- Engage from a spec, a drawing or just a problem to solve.
- Neutral labelling and neutral cartons available.
- MOQ by project — sample to container.
- Proposal with test data within three working days.
Your brand · our factory · one quality system
Single accountable partner from cell to certified pack.
Product lines we build on
Our OEM / ODM programmes draw on the same lines we ship under the EGbatt name — start from a proven platform or a clean sheet.
