I haven't shredded mine on 6 cells yet but on 7 cells I stripped 2 diffs in less than 5 charges. Course I've only been able to run 2 charges on 6 cells sofar with all the rain we've been getting. And even with 16/84 gearing, my speed meter showed 30 mph top speed so it's much better than stock and will wheelie on 6 even with the added weight of an aluminum brace and RX pack in the front.
