Lipo Charging rate

[Lon]

Here's a quote from ** LiPo BATTERY CHARGER SAFETY WARNING ** that's on the bottom of a battery charger description page.

"Never overcharge or exceed a 1C charge current.  A 1C charge current means the charge current equals the capacity of the battery.  For example, a 2200mAh battery should never be charged using a current greater than 2.2 Amps (2200mAh)."

My questions is:  If a battery specification says "Charge rate 3c" does that mean I can charge that "3c charge rate" 2200mAh at 6.6 Amps max?? Not 2.2 Amps as the warning says.

I'm thinking because of the Charge Rate of the battery specs being "3c", and not 1c. I can charge at that higher Amp rate.

Thanks,

Lon

Yes, that's what it means. There are contributors to another forum who have been charging at 2-5C for years, even before the batteries were marked for higher than 1C, and report no issues with shortened battery life, or anything else. Of course, most LiPo fires start during charging, so never leave a charging LiPo unobserved, especially at higher than 1C rates, and always have them in a relatively flame-resistant area or container.

Thank you WintrSol.  Appreciate your input to confirm my thoughts.
