Just a heads up these are advertised at 95% capacity and after testing 2 of the these cells, I'm seeing closer to 67% capacity. Now I'm only discharging to 2.8v, but I think going to 2.0v with lifepo4 is too low and probably wouldn't yield that much more. My test:
Charge to 3.65v at 4 amps and absorb until 2amp charge rate
Wait 5 min
Discharge to 2.8v
Wait 5 min
Charge to 3.65v at 4 amps and absorb until 2 amp charge rate
For the price ($5 per cell), I'm not that upset as I'm just going to use these for temp cells while hooking up 12v loads and prep for my camper van build. However I just thought I'd post for those that are looking to build larger packs with these cells.
