I put a H.V. 450mah 1s lipo in my DR28, and it's more than enough. The fact that it's easily removable now is sweet. I just use my 1s quadcopter batteries, and velcro them on the chassis under the body. I have PLENTY of H.V. 1s 450's around for my quads, so I pretty much have endless power for my DR28
Yep, you'll burn out the control board after too long. You COULD keep the factory 1s battery in the vehicle to power the board and the steering servo, THEN hook the drive motor leads from the board to a MOSFET, and then use the 2s battery to power just the rear drive motor through the MOSFET. You'd need a MOSFET that has a gate voltage rating of 2volts, and probably sime sort of a gate resistor. I dont know how long the drive motor would last with a 2s, but at least you wouldn't fry the control board or the steering servo that way.
