Default Gens Ace LiPo versus A123's

OK
After five years, I finally bought two Gens Ace 2200 3S1P batteries rated at 25 C. These LiPos will be used in a foamie picked up a few weeks ago.

Note that this is the first discharge test on the Gens Ace battery, further tests might improve things a little bit.

Basic info, the Gens Ace battery weighs 6.38 ounces, and measures 4 3/8 by 1 3/8 by 1 inch. My Cellpro Powerlab 8 charger shows its internal resistance at 9.5 milliohms.

Compare that to my 4S1P A123 pack. It weighs in at 10.4 ounces, measures 5 1/2 by 1 by 2 inches. The '8 charger shows its internal resistance at 6.8 milliohms per cell.

The A123 battery pack would then add four ounces to a model that weighs in at about 18 ounces.

Take a look at the discharge curves generated by the Western Mountain CBA battery analyzer.
