Dynacraft BMW i8 Concept 6v to 12v

Hey all, i am trying to upgrade my sons BMW i8 Concept to 12v, dual motor setup from the 6v, single motor setup.

I thought i would start by posting some pictures of the wiring and how everything is set up, so that you guys can get a better picture of what i have going on currently. I know not everyone will be familiar to Dynacraft stuff, so i figure this may help someone, whether theyre new like me, or have plenty of experience and just havent messed with the Dynacraft BPROs.


This is under the seat. 6v battery, 7a circuit breaker (shown by itself below) a 25a fuse, the motor (under the motor hood, probably gonna take this off), and the charger port. If you notice there is an extra provision for an additional battery. Im thinking for starters i am going to take advantage of this and the fact that there is another spot for a motor. Can anyone tell me what all i need besides another stock battery, wire, terminals, the other motor/gearbox and wheel drive, etc? Am i going to need to upgrade the circuit breaker and fuses?

The next image is of the underside of the vehicle. The top left plug is the foot pedal, the smaller red and blacks are the lighting wires, in line with the lighting is a 3a/250v glass fuse, next the red and blacks to the mp3 playing speaker/jack, the first plug on the side is the on/off switch, next the shifter (it only currently has forward and reverse) and finally the wires go back to the under-seat compartment..

Here is the 7a circuit breaker in the little black box under the seat.

And the charger port from the back side:
