What batteries to buy and why?

The 4000 cell graphs look a lot like the Flightpower 4900s from what I recall, although the edge may still go to the 4900s. But they are in the same league as the 4900s at least. So there is promise in the new 30c line of kokams. I'm told there should be a couple new sizes every month or so unti the whole line is 30c.

The last two lines are 40c and 45c.... voltage is sagging but that is huge amps.... 160 and 180 amps.

The 20-30c lines are very good... in the 3.3-3.5v range for most of the capacity. I would like to see the capacity hold up a little more... oh well.
