Custom lithium-ion, LiFePO4, and NiMH battery pack assembly with BMS integration, safety testing, and export certification support.
Overview
Keiteq Direct assembles custom battery packs for industrial, automotive, and consumer applications. We work with lithium-ion (18650, 21700, pouch, prismatic), LiFePO4, and NiMH cell formats, integrating battery management systems (BMS), protection circuits, connectors, and enclosures to produce a complete, tested pack. Our team supports UN38.3 and IEC 62133 certification processes. This is a growing capability at Keiteq, with increasing capacity and expertise in battery pack assembly for Southeast Asian and global markets.

How we work
Our Process
Specification Review
We review your voltage, capacity, discharge rate, size, and certification requirements to select the right cells and BMS.
Prototyping
A prototype pack is assembled, tested, and submitted for your approval before production tooling is committed.
Production Assembly
Cells are sorted, welded, BMS-integrated, and assembled into enclosures on our dedicated battery assembly line.
Test & Ship
Every pack is capacity-tested and safety-verified before being packed and shipped with full test records.
