What is the highest voltage battery pack i could put in my ntc3?
I have a radio shack 1 hr charger that can take 7.2 & 9.6 volt wired packs and 6.0, 7.2, 9.6 box packs.
I have some 7.2 packs that i would like to use if posible.

6v is the highest you can run through receivers and servos. Anything more may damage them.

Then why do most reciever's have BEC on them???? I was allways under the impression that BEC was for Battery Eliminator Circutry, meaning that you could run your Rx off the car's 7.2v battery pack and not have another Rx pack like Nitro has. I know this stems from the days of mechanical speed controller's, cause most ESC's have it built in,bit I have seen a few Rx's with this circitry still.

BEC is an ESC feature, not the receiver.

6.0v is usually the maximum voltage receivers can take, but some are SPECIFIED that they can take higher voltages such as the Fury which can take 3.8-27v. Servos aren't as picky about voltages but receivers are.

Right, & since brncat1 was asking about a pack for his NITRO TC3, there would be no ESC to speak of, & the reciever NEEDS a battery pack to run....:cool:

you may blow up your Rx if u put anything over 6.0v in it. The ESC has BEC which limits the voltage into the receiver. The little black white and red plug on an ESC only has 6.0v going through it.

My reciever runs fine of 7v. 7V is what my receiver pack puts out for about 5-6 tanks of fuel, then drops down in the 6.5-6.7V range.

ya, but Reciever's have been around alot longer than ESC's. I remember my first RC, the car pack plugged into the reciver directly. The Rx acctually has BEC printed on it, I have still seen alot like this to this day. mostly AM one's tho
