Frist off this is the Bit Char-G forum. This should be in ZipZap. *shrug* An admin might want to move this, but No harm, no foul. Most of us have atleast one of each anyway. Besides, Dual celling is the same on both. And I'm sure this has been asked a dozen times already and probably could have been searched for, but it's a good question.

Now, you've got something wrong with the battery connections. When it's on the charger your car is able to get power directly from the remote batts, you can even pull the batt out of the car and run it on the remote. But, pull it off the charger pad and it's all on the car battery again.

Anyway, check this stuff:

Batteries have same amp rating.
Batteries in series.
Batteries in correct polarity.
Batteries have good firm connections.
You didn't break a wire connection while you were inside.

Let us know.

i figured it out, the second battery i used was a bad one so i took it out and it works fine. now i bought two 150 mah batteries of tinyrc and i dual celled my bit. it has power off the controller but when i charge it it makes a wierd sound like the batterys exploding or somthin and when i take it off the charger it goes a little bit but it doesnt have the full dual cell power should i charge it longer or what?

Don't forget not to overcharge it. Doing the 4 battery custom charger thing messed up my car batteries one time. I ended up frying 2, and had acid come out of my battery part of the charger. Time it.
