I do not understand you? Where's the matter?

1/8 use larger batteries than touring since they use two, so they have twice the voltage. That is the same as using a single 12 nimh cells or 4s2p lipo pack.

Also, with a bigger car you can use larger capacity packs (8000mAh) because room is not a worry for you.

In touring car 8000 mah lipos are diffcult to fit.

In spite Novak has designed their conversion kit to work with 15 volts the HV can handle even higher voltage.

Once more, I do not understand what the matter is Mark.
