4.2V/cell x 4 cells x 5 Amps = 84 Watts.
This is a very common question, members wondering why a 50W charger won't do more than about 3 Amps on a 4S pack.
So will this charger charge a 4s at all even if it's slowly or it won't charge 4s at all? At this point it's not a real big deal if it doesn't as I am not running any 4s batteries for the time being but if I do happen to use them in future will I need to update charger?
