Is it possible?
 

Is it possible for my Rhino 5s1p 4900mAh to hold over 5000mAh? currently it charging and is up to 5108mAh charging at 20.89v - 20.99v using .01 - .2 AMPS. im guessing its near the end of the charge cycle since its at that low of amps. thoughts? My turnigy held over 5200mAh and its only rated @ 5000mAh

Yep, some lipos have been know to hold more than their rated spec. Maxamps used to use a 4000 spec cell (written on the foil) in their 3000 packs....

you may want to bump you lvc up some

its up to 5127 now and still going, its safe then right? its not heating up or anything and holding at 20.99v @ .0 - .2 AMPS

If the pack is staying cool during the charge, and you are using a lipo changer with cc/cv profile you will be fine. Maybe a pic of your charging setup, just in case.

Also note that when using a balancer it discharges the higher cells. So as it bleeds off to balance it still has to put that back in for a full charge in the end

Erevonut makes a good point, as the balancer does its work it will draw out the pack a bit, and the charger will put in addl mah to top it off again.

5144mAh thasnk guys its done now
