What did you discharge them down to? 3.7V, 3.6, 3.5V? This is ~ 77% ) which would be expected ~ 3.7V roughly 80% of the usable charge.

Just curious. Will probably check mine as well.

Good question! Went down all the way to 3.0V.

Good question! Went down all the way to 3.0V.

I thought you weren't supposed to take lipos lower than 3.2v per cell otherwise you could potentially damage the pack

@Mike-h yes correct. In fact jkflow mentioned it, you probably want to stay close at around 3.7V per cell.

3.0V is the lowest I would go only when testing for full capacity. For science!

PS. Wouldn’t ever do this on my SMC packs .

 

[jkflow]

Yeah, shouldn't go below 3.2V but at low c and not leaving it there for a long time will minimize any degradation.

Note, under high C, do not go below 3.5V.

Getting similar results on my lipo.
Discharged to 3.5V (~0.6A load), recovered to 3.6V (this is at best 20% of rated capacity) and by all means anything below 3.5V is not usable.
Boring math:
20% of 2800mAh = 560mAh i.e. I should be able to refill 2240mAh. I got 1940mAh.
So basically it's a ~2500mAh pack. That is outside the industry standard of 5% error on marking.
