ASOL 103665 Lithium Polymer Battery — A high-capacity rechargeable Li-Po soft pack battery engineered for power-hungry portable electronics and industrial devices. Delivering an exceptional 3000mAh capacity (11.1Wh) in a compact 10.5mm × 36.5mm × 68mm form factor, this battery provides extended runtime for power banks, tablets, POS terminals, security cameras, portable medical devices, GPS navigation systems, and other high-drain applications. The aluminum-laminated soft pack construction offers superior energy density, lighter weight, and greater design flexibility compared to cylindrical cells, while the multi-certified profile (UL, CB, KC, PSE, UN38.3) ensures compliance across major global markets — making it an ideal battery cell for OEM/ODM product development and wholesale deployment.
🔋 Why Polymer vs Cylindrical?
Unlike traditional cylindrical batteries (such as 18650), lithium polymer batteries offer:
- 📏 Thinner & Flatter Profile — Slim 10.5mm profile fits sleek, modern device designs better than bulky cylindrical cells
- 🔄 Flexible Shape — Adapts to custom rectangular and curved enclosures in tablets and power banks
- 🪶 Lighter Weight — Reduced weight improves portability for handheld and mobile devices
- 🔒 No Pressure Vents — Safer for sealed consumer electronics and medical devices
- ⚡ Higher Energy Density — More capacity in a slimmer form factor for all-day power
- 🛠️ OEM-Friendly Customization — Wires, connectors, protection circuits, and branding available
