Custom Lithium Polymer Battery Manufacturer – OEM/ODM Solutions for IoT, Wearables & Medical Devices

Introduction

Are you searching for a reliable custom lithium polymer battery manufacturer for your next IoT sensor, wearable device, or medical product? At A&S Power, we specialize in designing and manufacturing high-quality lithium polymer (Li-Po) cells and battery packs tailored to your exact specifications. With over a decade of experience in OEM/ODM projects, we help product developers and procurement professionals bring their battery-powered innovations to market – faster, safer, and more cost-effectively.

A&S Power is the parent company of <a href=”https://aspowerbattery.com“>Enerbe</a>, our LiFePO4 energy storage brand serving commercial, industrial, and lead-acid replacement applications.

What is a Lithium Polymer Battery?

A lithium polymer battery (often abbreviated as Li-Po or Li-poly) is a rechargeable battery that uses a gel-like polymer electrolyte instead of the liquid electrolyte found in traditional cylindrical lithium-ion cells. This solid-state design allows for ultra-thin, lightweight, and flexible form factors – making it the ideal power source for compact consumer electronics, medical wearables, and IoT devices.

Unlike rigid 18650 or prismatic cells, lithium ion polymer batteries can be manufactured in almost any shape or size, giving product designers the freedom to optimize space and battery capacity without compromising on device aesthetics or ergonomics.

At A&S Power, we are a dedicated lithium polymer battery manufacturer that offers end-to-end customization – from cell selection and BMS integration to final packaging and labeling.

Frequently Asked Questions (FAQ)

What is the minimum order quantity (MOQ) for custom lithium polymer batteries?
Our MOQ depends on the cell size and complexity. For standard pouch cells, MOQ starts at 1,000–3,000 units. For fully custom packs with BMS, we can work with lower quantities for prototyping.
How long does a custom battery project take?
From specification to first samples, typical lead time is 2–4 weeks. Mass production takes 4–6 weeks after sample approval.
Do you provide UL, CE, RoHS, and UN38.3 certifications?
Yes. We can supply all required certificates with your order. For fully customized cells, we assist with the testing process to obtain them.
Can you include custom connectors, wires, or labels?
Absolutely. We support any termination type (JST, Molex, custom wiring) and offer OEM labeling with your brand logo and product information.
What is the typical cycle life of your lithium polymer batteries?
Under standard conditions (0.5C charge/discharge, 25°C), our cells deliver 300–500 cycles to 80% capacity. With careful design, we can extend this to 700+ cycles.
Do you ship globally?
Yes. We ship by air (UN38.3 certified) and sea freight to customers worldwide, including North America, Europe, Asia, and Australia.
