C-rate conversion: Panasonic NCR18650 (2800mAh)

C-Rate	Current (A)	Theoretical runtime
0.2C	0.56 A	5h 00m
0.5C	1.4 A	2h 00m
1C	2.8 A	1h 00m
2C	5.6 A	30m

Highlighted row is closest to the rated 5.4A continuous discharge.

Charging

Rate	Current	Estimated time
0.5C	1,400 mA	~2h 00m
Standard	1,925 mA	~1h 27m
1C	2,800 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 PacksMarginal. Check your motor's peak draw first. You might get voltage sag 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.

FlashlightsDecent runtime. Works well for most flashlights.

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.
