TIANQIUCustom Battery Pack Manufacturing — OEM / ODM
Design, engineering and assembly of custom battery packs — NiMH, Li-ion & LiFePO4 with BMS, custom connectors and housings, under your brand.
How are custom battery packs built?
We engineer and assemble battery packs to your exact voltage, capacity, size, connector and safety specification.
Design
Cell selection, voltage & C-rate, BMS and packaging
Assembly
Precision welding and automated assembly
Test & certify
Capacity, safety & transport testing (UN38.3 on the lithium packs)
Which chemistries can a custom pack use?
Match the chemistry to your cost, energy and cycle-life target.
| Chemistry | Cell Voltage | Key Benefit | Typical Use |
|---|---|---|---|
| NiMH | 1.2V/cell | Rechargeable, long cycle life, eco-friendly | Consumer & industrial |
| Li-ion (NMC) | 3.6V/cell | High energy density, long cycle life | E-bike, power tools, consumer |
| LiFePO4 | 3.2V/cell | Safe, long cycle, high power | Storage, UPS, industrial, EV |
What can be customised in a battery pack?
Every pack is configurable — from cells and BMS to the final label. With group manufacturing for storage and e-bike modules.
- Custom BMS, protection & cell balancing
- Spot welding, potting & encapsulation
- Custom housings, wiring & connectors
Cells we assemble into packsCR2032-CR2450 lithium, NiMH and Li-ion cells, graded in-house before assembly.
Housings & cases moulded in-houseInjection moulding for battery holders, cases and enclosures.
Production & test lineCapacity grading and safety checks before packing.How is each pack configured?

How does the custom pack process work?
A clear 5-step path from requirement to a certified, tested production sample.
Requirement & design
Voltage, capacity, size, connector and C-rate defined.
Cell & BMS selection
Cell chemistry, BMS and protection matched to your load.
Prototype
Sample pack built and tested against your spec.
Assembly
Precision welding and automated assembly.
Mass production & QC
Batch capacity & safety testing before shipping.
Where are custom battery packs used?
From mobility to storage — a pack for every application, engineered and certified.
Serving e-bikes, UPS, energy storage cabinets and inverters through our group manufacturing.
Are your battery packs certified?
ISO 9001 · UL (selected product lines) · UN38.3 (lithium cells) · CE · RoHS · EU 2023/1542. Factory-direct with maritime & air transport certification.
What is the MOQ and lead time for a battery pack?
| Product | MOQ | Notes |
|---|---|---|
| Custom battery pack | Project-based | Design & sample first, then MOQ per pack |
| Standard rechargeable AA/AAA | 50 cartons | Retail & industrial |
