Thats huge mah for it to only be at 3.82v/cell (roughly 41% capacity).
Are you absolutely sure you're charging on lipo mode? Its not cutting off since its not getting to 4.2v/cell (max cell voltage). As long as you're charging in lipo mode and its operating correctly, the CC/CV mode will terminate after voltage has reached 4.2v/cell.
both chargers are operating correctly in lipo mode, it sounds like both chargers have serious accuracy issues with their mah measurements. One charger I might understand, but two? Doesn't seem likely. That number simply can't be what it appears to be.
How old are these lipos, how many cycles? What brand, mah, C rating? You're balance charging?
