General Lipo question
 

Just a general question. When the charge goes from CC to CV its at 90%, right?Thanks

Depends. My emoli cells are technically not "lipo", but the CC lasts for about 2/3 the charge, with the CV stage for the rest.

Well i'm running a PQ 3s 3700 and two maxamps 2s 8000mah Lipo's it went to cv at 4.2v cut-off. Would the point where they went to cv be the 90% point?

I'm not sure I understand the question, but the point where it switches from CC to CV is right when the battery hits 4.2v/cell. Whether that's at 90% or not is really irrelevant. If you are charging 8Ah batts, then 90% charge would mean the charger has put in 7.2Ah into the battery. Is this what is happening?

Thanks, I'll just let it kick off when done.
