Joe, very nice work on the lipo comparison.

Got a new charger for Christmas. My new TP 820 displays charging in Amps rather than my old 610 which displayed charging in C. Argh this Amp verse C(rap) continues to drive me insane.

Help please confirm the calc for accurately converting C to amps for a given #mah lipo rated at #c constant / #c burst.

Example Nano Tech 3850mah 6s 65c lipo rated at 8c max charge.

3850mah / 1000 = 3.85amp x 8c = 30.8 amp max charge rate / correct?

However for a Nano Tech 2850mah 6s 65c lipo rated at 8c max charge.

2850mah / 1000 = 2.85amp x 8c = 22.8 amp max charge rate / correct?

If mfg charging C rating is not stated for a lipo then what is the safe calc for determining the # amp max charge rate instead just using of the default 2c rule?

Example Genace 2000mah 3s 25c

2c method 2000mah / 1000 = 2amp x 2c = 4amp max charge rate / correct?

xc method ?

Calculating the max C charge for a Lipo that isn't clearly indicated / I found the what appears to be the the methodology, calculations and rational explained on these threads:
