Ok so I just got a fast charger and I'm not sure how many amps I should charge a 2s 5400 mah batt
Drive it like you stole it!
I would also like to know more about this...I would say 5 amps but not sure
You ain't bashin unless your crashin!!
Common rule of thumb is 1c charge rate so that would be 5.4 amps. Above all what the manufacturer recommends is what you should do. This question really needs to be directed to the manufacturer or vendor you bought the battery from. Traxxas does not allow tech support for other companies products on this forum.
