ASOL is a lithium polymer (LiPo) battery manufacturer producing thin, lightweight, made-to-shape 3.7V cells and packs for wearables, IoT, medical and consumer electronics. When a product needs a battery in a specific size and weight, we build it to fit.
📑 Table of Contents
1. Why Lithium Polymer
Lithium polymer cells use a flexible pouch format, so they can be made remarkably thin, light and in custom footprints that cylindrical cells can't match. That makes LiPo the go-to chemistry for slim, space-constrained devices.
2. Custom Sizes & Capacities
From tiny cells under 100mAh for earbuds and trackers to several-thousand-mAh packs for tablets and handhelds, ASOL builds to your exact thickness, length, width and capacity — including ultra-thin and ultra-low-temperature variants.
3. ASOL LiPo Range

4. OEM/ODM Capabilities
- 📐 Custom dimensions, capacity and discharge rate
- 🛡️ Integrated protection circuit (PCM) and connector of your choice
- 🌡️ Options: high-rate, ultra-thin and low-temperature cells
- 🏷️ Private-label printing and packaging
5. Devices We Power
- ⌚ Wearables, earbuds and smart trackers
- 📟 IoT sensors, beacons and POS devices
- 🩺 Medical and personal-care equipment
- 🎮 Consumer electronics and remote controls
6. Quality & Certifications
Every cell is tested for capacity and safety; shipments are certified to UN38.3 with CE and RoHS compliance. Full test reports are available on request.
