Most low discharge (C) battery is recommand to change at 1C by manufacture. so 10,000mah is recommand to charge at 10A. For high discharge battery 50-60C it is recomand to change at 1-2C. The limit is as high as 5C for some brands. LRP recommand to change normal 2S 5000-6000mah lipo at 10A and 1S 1/12 battery at 8A。 But remember don’t try it wiht anything lower than 50C 。
Well, I stated there as well. "But remember don’t try it wiht anything lower than 50C 。" If Sunday Hing like to read half of it I have nothing to say la......
SMC instruction sheet, also mention, 2C to charge is acceptable. As i know a lot of people included myself is using 10A to charge 50C. And some will even use high V to charge it to 4.22-4.23v. After 3-4 months of usage, my SMC battery still keep very flat.
The key is to run it fo 6-7mins, stop playing at around 3.8/cell, let it cool down for another charge cycle.
