I am new so any help from experts will be greatly appreciated. QUestions:
1) I have following batteries:
a)NiCD 7.2volts sub-cell C, 1500mah battery
b)NiMH 8.4Volt sub-cell C, 4500mah battery
c) NiMh 7.2Volts sub-cell 2/3A 1100mah Battery?
d) LiPo 7.4 Volt 2S , 900 mah
e) LiPo 11.1 Volt 3S, 1800 mah.
What current should i charge them at ? What is the best charing current and whats the MAX current i can charge at?
2) If i charge at higher current and battery becomes warm. DOes that mean its charged?
3) for same volts and same mah capacity battery.. one is sub-cell C and another one is sub-cell 2/3A (for mini trucks) are charging current/volt same?
4) Some people say chargin at very low current for longer period is good. Is that right? Does chargin at higher current give u same/similar amount of juice in battery quicker? Only that it reduces lifetime of battery?
Help me guys.. I need it
