Just noticed my battery packs exceed the perimeters for sabretooth controllers, 25v with 42 batteries? Way over. I'm assuming I can modify the packs I've bought so that I use less cells, this depends on how much current I need, would 3300mAh be enough for a 4wd 18v pusher?
I think I could modify it and change them to two packs of 12v 3300mAh, but that would leave me with 20 cells, which I noticed Gary said in another thread burnt out sabretooth controllers he had bought. 10.8v batteries? That keeps me in the perimeter? Aaaaah

Edit: Or simpler, 25v with 21 cells, that doesn't exceed the perimeters by much and drops half the cells? Thoughts are desperately needed!

Thanks again
