Charging
| Rate | Current | Estimated time |
|---|---|---|
| 0.5C | 1,512 mA | ~2h 00m |
| 1C | 3,023 mA | ~1h 00m |
These are estimates for the constant-current phase. Real charge time is a bit longer because of the slow taper at the end.

Frequently asked questions
Handling and safety
Lithium cells can be dangerous if mishandled. A few things to keep in mind:
- Never charge above 4.2V or discharge below 3.2V.
- Store cells at around 3.6-3.8V (roughly 40-60% charge) for long-term storage.
- Don't mix cells with different capacities, chemistries, or states of charge in a pack.
- Inspect wraps before use. A torn wrap can cause a short circuit.
- Always use a BMS or balance charger appropriate for your pack configuration.
- Keep cells away from metal objects, keys, and coins. A short across the terminals can cause fire.
