如果差完電唔玩有無事ka?

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.
