Mini vs large batteries
 

Is the only difference size?

no, large has more capacity and provideds higher ROF than a mini, even though its the same voltage

Alright, because I just got my new wood kit, and large won't fit in the stock, so I was gonna buy a mini 8.4 intellect. Or I could just cut the stock out, but I'd probably fail.

If current bandwidth is an issue, yet you need it to fill a compact space; maybe consider converting to Dean's Ultra plugs?

lipo!

If you switch to Lipo, make sure you have a charger that can handle lipo batteries.

just curious, which wood kit wont take the large battery?
