That's how it looks like with lipos. 1P is 2,7 ponds.
The electrics besides the ESC are voltage-controls for 16 cells plus a voltage control and limiter for the receiver-lipo.

BTW: The 3080 has the same diameter but is 40 mm longer, heavier (3,5 ponds) and of course more powerfull if not to say too powerfull for this car.
