Also if i am anly going to ever run 2s batts is it worth it to get highend charger for higher than 5amp rates is there a benefit other then faster charge times.
Well if the baterys says it can be charged in 2c or 3c or 5c that is no problem.
1c is the actuall mahs of the batery. 2c is the double of the mahs of the batery.
A double C means half the time to charge.
Minium 100w charger for you if want to charge at 1c, that is more then an hour....
if you want to charge in 20minutes you need a 400w or even higher charger!
I charge my 5s (18.5V) lipo with a 50w AC/DC charger, and select 5.0A...but the charger only charges at 2.5A and gets extremelly hot...so i need a new charger to charger faster and cooler! :P
