Project Guide

An OEM Lithium Battery Project From Enquiry To Container

The specification items that decide a private-label project, why the sample stage is not optional, and the documents to plan early.

A private-label battery programme is mostly a documentation exercise. The manufacturing is the straightforward part; the failures happen where an assumption was never written down.

What Goes In The Specification

Capacity, nominal voltage and the application the pack serves
Case: dimensions, material, mounting points, IP rating and terminal type
BMS: continuous current rating, protection thresholds, balancing behaviour
Communication: Bluetooth, RS232, RS485 or CAN, and the devices it must work with
Options: heating for cold climates, monitoring, display
Label artwork, brand marks, serial number scheme and language
Carton, pallet pattern, and whether the packing must satisfy air freight

Why The Sample Stage Is Not Optional

A sample is prepared for your test before the bulk order, and that sequence exists because a specification is a description while a sample is the thing itself. Test it on your own load, with your own inverter or charger, in the enclosure it will live in. Changes found at this stage cost a revision; changes found on arrival of a container cost the container.

Plan The Documents Early

UN38.3 and the MSDS decide whether the goods can be shipped at all, and CE, IEC, UL and ROHS may be required by your market. Name the destination country at the specification stage so the document set is planned rather than chased after the goods are built.

A Realistic Sequence

Enquiry with application, target capacity and volume expectation
Specification drafted and agreed in writing, including options and label
Sample built and shipped for your testing
Your approval, or a revision round if the test finds something
Bulk production against the approved sample as the build standard
Documentation, packing and shipping to your port
After-sales support against the same specification everyone signed

The most useful thing a buyer can send at the start is not a product code. It is the application, the constraints and the volume, because those three decide everything else.

FAQ

Questions On This Guide

How long does an OEM project take?

It depends on how much is custom. A branded label on a standard pack is quick; a bespoke case with new tooling is not. Send the project and you will get a schedule rather than a range.

Can I own the design?

That is the ODM route, where the pack is developed around your requirement. Agree the position on the design and the tooling in writing at the start rather than after the first production run.

What volume makes this worthwhile?

It varies by how custom the product is. Ask with your real annual expectation and you will get a straight answer about whether the project makes sense.

Do you sell the same pack to my competitor?

For a standard product with your label, the base product is a catalogue item. For an ODM design developed for you, the exclusivity position is part of the agreement - raise it early.
