opinions about batteries....

Two quotes from Charles on RCG:-

Re TP 65c 2250mAh:

IRs approx. 1.6 but they are still dropping. They were 2.3 after the first 4A charge form storage.

Re Hyp 45c 2200mAh:

3rd.Chr. on Cell Pro 10 at 5A IRs 3.6 / 3.7
4th. Chr. Cell Pro 10 at 7.2A 2.6 / 2.7

And a quote from you on page 2 of this thread:

Pack IR is actually the only story as far as performance goes.

If you are both right, the TP pro power 65c cells are about 50% better than the Hyperion EX G3 45c cells. The graphs don't shout that out to me, but maybe its the comparison between 2s and 3s packs, and the fact that the 2V or so that we're concerned with occupies so little hight its not easy to compare them.

Okay, sorry for not seeing him saying they were 1.6 IR for 65C, but again, those are pre-production samples, and most likely selectively picked for testing. The G3 45c pack has 2.1 IR after a few cycles on them.

I don't know if Charles graphs are not calibrated or something, but you look at the actual number on the graph at a given discharge current, but the G3 45C pack is holding a higher voltage PER CELL. 1.6 IR for a 2250mah pack is simply amazing though... my 4200 35C G3 packs were 1.33 IR, almost twice the size pack.
