I have a DC charger that works a little like the Passport in that can use capacity, time or voltage to terminate lipo charging. For capacity, since you never know if your cells underrated, I set up with headroom - usually 10-15% so for a 5000mah I'd set it at 5500mah. If it stops at 5500mah, and it will be the exact amount so you'll know what causd the termination - then reset the capacity higher next time.
You want to get capacity set high enough so the charge terminates on voltage - thats means the lipo is fully charged. If you're not getting close to 4.2v/cell, up the capacity until the terminate on voltage like they should.
Thanks for that info.
So I can expect the Ultra to detect the voltage peak and cut off when appropriate I assume is what you're saying, yes?
Also, regarding the MAH, can the charger differentiate between a partially charged and a drained battery with regard MAH specifically? In other words, is is ok to put a 3/4 charged 5000 battery on the charger with the capacity set at 5500MAH, and know that it will cut off at 5500MAH (V peak aside)?
Apart from those questions I understand. You want to figure out the true MAH capacity of every battery you have so that you can set the MAH cutoff to that +10% or so, for safety, but still assuring that the peak VDS is what cuts if off, right?
Thanks so much for the info.
Regarding discharge, the ultra defaults to 3.0VDC as a cutoff for discharge. Isn't this a little too low? I thought I'd read that you don't want to go under 3.3 or so?
