Charging

Rate	Current	Estimated time
0.5C	1,600 mA	~2h 00m
1C	3,200 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.

Application suitability

PowerwallsHigh capacity means more stored energy per cell. Fewer cells needed for a given kWh target.

Ebike PacksGood balance of capacity for range and discharge for hills. Works well in most ebike packs.

Car AudioEnough discharge to handle amplifier bursts without voltage sag.

High-Drain VapingAbove the 25A Mooch CDR threshold. Suitable for regulated and mechanical mods.

FlashlightsHigh capacity means long runtime. Great for everyday carry and extended use.

Power ToolsSufficient discharge and capacity for most power tool packs.

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 2.5V.
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.
