Thanks again for taking the time to do this testing Doc - I know these cells really well, they powered a whole series of prototypes for me, so your tests give me an excellent baseline to compare other cells to. Sometime I would love to see the 35ah curves for your recent tests (yesa, headway, PSI, and ebikes.ca) overlaid, ah and wh - but is Friday night, you have worked hard, I hope you are out having fun.

<grin> Oy, Cheer Ocean and the Flintstone Chargers (sounds like a cheap cover band) from the fleet of first generation of LiFePO4 packs I tested in summer of '07. This is the only one of those cheap packs I kept - I had overdischarged cell#11 on both 36v packs when bank#11 on a flintstone charger died , didn't seem right to pass them on like that. I later replaced the dead cells with two spare falconEV cells (like the ones doc just tested), and right now they are on the Prototype I am using to mess around with gear motors. That generation was the first and worst, but it definitely has lasted long beyond the three months an early naysayer was touting
I have a Cheer Ocean full-pack discharge curve from the dark ages, at a piddly 2.37amps:
BTW Gaston, thank you too, for sending the cell to Doc for testing!
