A quick decision matrix.
Different design constraints push you toward different lines. Here is how we usually steer customers.
| Constraint | Polymer Li-Po | Custom-Shaped Li-Po | Coin Steel-Shell |
|---|---|---|---|
| Capacity envelope | 15 mAh - 20 Ah | Same, in non-rectangular form | 10 - 180 mAh |
| Form factor | Rectangular pouch | Any 3D geometry | Round Ø 10-25 mm |
| Cycle life | 500+ | 500+ | 500 - 1,000+ |
| SMD reflow capable | No | No | Yes (ML series) |
| Hermetic enclosure | No (laminate) | No (laminate) | Yes (steel can) |
| Lead time (samples) | 20-25天 | 35-45 days | 5-10 days |
| Typical applications | Wearables, IoT, drones | Smart glasses, hearables, medical | Hearing aids, RTC, sensors |
