anyone try running 10 nimh cells in series on their MMM?

[blueb8llz]

that would total up to 24 volts and the mmm can handle 25.2volts. only reason im thinking of doing this is cus after running my 4s lipos, instead of charging them for 2 hours, i can convert my nimh cells to 10 cell packs since i have two 7 cell packs, and two 6 cell packs. i havent tried running my 7xl/mmm combo with the 6 cells yet, but im sure its pretty slow. so instead of having two sets of slow power batteries...why not make one decent 10 cell.
what do you guys think? any suggestions or ideas or comments?
