thanks guys for the good info , now i just found out my triton charger can only charge upon to 5000 mah ...
my question is i will not be able to charge any lipo cells greater then 5000 ? or if there's way around it ?
No, you can charge any capacity - you will only be able to charge at 5amps since its the chargers max charge rate. If you have an 8000mah 2S lipo, you can charge it at 5amps, it will just take a little longer to charge fully. The charger asks for the lipo capacity to calculate a 1C charge rate, if thats larger than teh charger can charge at, it will just use the max charge rate of 5amps.
