    Parkzone 11.1 1800 mah Lipo battery

    I have a Parkzone T-28 Trojan, it came with a Parkzone 11.1, 1800 mah lipo battery, the plane has only been flow 3 times. I charged the battery this morning with the Parkzone supplied battery charger, after the battery was all charged up, I checked it on my Hyperion EOS Sentry voltage tester, and it only charged to 84% capacity (12.7 volts total), I tried to charge it again, and the same thing, only 84% capacity (12.7 volts total)!!? What gives? Do I need to get a new battery already? I read some not so good reveiws on Parkzone batteries, if this battery is on it's way out I want to replace it, can anyone recommend a good brand of battery?
    Thank You,
    Paul

    12.7v 3cell is over 4.2v/cell- I say it's fine....
    Hello, the IMAX b6 quattro fits the bill?

    12.7 is more like 110% and not 84% !
    a full 3 cell battery is 12.6v and OCV (open circuit voltage) capacity meters are inherently inaccurate.
    My dualsky 5s 5000mah and polyquest 5s 5000mah have different voltage on 2500mah charge.(about 0.2v difference)
