[NSRCA-discussion] Batteries

 Oh OK Chad I didn't know that. That is really interesting. Either way my thoughts on the TrueRC packs is that the price is certainly worth considering. If as good as they seem it changes the cost structure of flying Electric. Mike

extreme abuse (I should know! :) ) is in large part due to a 4p config 
rather than 1p as in the current packs. In a 1p when that cell gets 
weak its over, in a 4p when a cell gets weak the other 3 in the 4p can 
help it along for quite a while before they all get weak.

I am really convinced that a move to 1p config packs has brought with it 
lower useful cycle life. I feel you need to be a lot more cautious with 
the 1p packs than the 4p's, or they will not last you very long :)
