Independent test data: Mooch's test of the K10 ↗

At the standard 500 mA charge rate, a full charge takes about 2 hours. The last bit is a slow taper to top it off.

0.5C	0.5 A	2h 00m
1C	1 A	1h 00m

Highlighted row is closest to the rated 8A continuous discharge.

Charging

Rate	Current	Estimated time
0.5C	500 mA	~2h 00m
1C	1,000 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

PowerwallsToo low capacity for practical powerwall use. You'd need too many cells.

Ebike PacksNot enough discharge for ebike use. Voltage sag would be a problem under load.

Car AudioNot enough discharge for car audio amplifiers. You need at least 15-20A continuous for most setups.

High-Drain VapingBelow the 25A Mooch CDR threshold that high-drain vaping needs. Use a higher-drain cell.

FlashlightsLower capacity means shorter runtime. Better cells are available for flashlight use.

Power ToolsNot enough discharge or capacity for power tool use.

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.
