What is a High Capacity Lithium Polymer Battery?
A high capacity lithium polymer battery typically refers to cells with capacities of 1,000mAh and above, with some designs reaching 10,000mAh or more. Unlike standard polymer cells used in compact wearables, high capacity variants prioritize runtime and energy density, making them suitable for power-hungry applications.
Key characteristics:
| Feature | Description |
|---|---|
| Capacity range | 1,000mAh – 10,000mAh+ |
| Nominal voltage | 3.7V – 14.8V (custom configurations) |
| Energy density | High – more power in compact footprint |
| Cycle life | 300-500+ cycles |
| Customization | Shape, size, BMS, connectors |
| Certifications | UL 1642 tested, CE, RoHS, UN38.3 |
Common Applications for High Capacity Li-Polymer Batteries
| Industry | Applications | Capacity Typical Range |
|---|---|---|

How to Choose the Right High Capacity Battery
Step 1: Define your runtime requirements
Calculate how long your device needs to run – this determines the minimum capacity.
| Runtime Target | Estimated Capacity (at typical consumption) |
|---|---|
| 2-4 hours | 1,000 – 2,000mAh |
| 4-8 hours | 2,000 – 5,000mAh |
| 8-12 hours | 5,000 – 8,000mAh |
| 12-24+ hours | 8,000 – 10,000mAh+ |
Step 2: Consider physical space
High capacity batteries are larger. Ensure your device has adequate enclosure space.
Step 3: Choose the right voltage
Match your device‘s voltage requirements – single cell for 3.7V devices, multi-cell for higher voltage systems.
Step 4: Evaluate BMS requirements
Does your device need communication (I²C, SMBus, CAN) or just basic protection?
