then type in SMC and look at there 3000 and 3300 selection great company for batteries and id say most agree!
a Good Charger if ur not gonna get 100% serious is the intelli peak charger "digital peak" its ac/dc peak charger great price does a good job of charging
batteries r as follows :
1500 5 minutes
1700 6 minutes
1900 6 minutes
2000 7 minutes
2400 7 minutes
3000 8 minutes
3300 9 minutes
and not to hit manstream yet but 3600 10 minutes
the time the battery last may vary from track to track and gearing and tire size
those minutes r easy to get if u r just going up and down your street also
differences in battery types r Nicad's usually get a lil warmer in heat can be charged a few more times then a Nimh can a day and the battery has a memory of how you charge it it also when the voltage drops off the battery just dies then you recharge it.
with nimh batts only get warmer when charge at higher rates then recomened they usually shouldn't be charged no more than 3 times a day 4 max they don't hold a memory like nicad and when the battery dies it drops off in voltage like a slight downward slop then it dies then u got back to the pit and re charge it after it sets for 30 mins to let the internals of the battery cool properly
hope this lil reply to your forum will help u along the way!
also seek advice on some one helping you put deans 2 plug connectors on your batteries they provide more efficent electricity to the speed control and the motor and make for a better setup overall
