dual cell problem ....... again
well i did the dual cell mod it was just a bit of a sloppy job because it was my testing chasis but i did it correctly. i thinks it just how it should be. i give it about 6 multipul charges ( all in 1 go controller mod ) and for some reason my car is super fast for about 8seconds then just dies out. what is wrong??
im using dual 150mah nimh cells by the way

Check all of your connections. If you did it like the instructions at QFM, then the battery in the body might be grounding itself. If that's the case then you're burning up all your juice to heat up the wire running between the batteries.

Go back and make sure that all of your wires/connections are only touching things they are supposed to touch. It sounds like you might have a short. With the QFM instructions, there is a bit of a tendancy to not totally insulate the negative pole of the battery in the car. That makes the batteries just fight each other and drains all of the charge. But it could be any one of your connections if they aren't properly insulated.

i found the prob AGEZ ago mate 
you gotta build a stand alone charger.
think like this........ there are 2 batteries in the controller to charge 1 battery in car. u need 4 batteries in charger to charge 2 batteries in car! 2 batts dont push out enuff voltage to charge 2 batts
hope this helps!
