Hey everyone, just got my son a Summit for Christmas to go with my Stampede 4x4 and Ken Block. I got a lipo question. Just bought 2 Venim 2s 5000mah 40c batteries and really love the punch and power but the balance is way off on charging them. Is that common or anyone have that issue before? I'm talking like 3.91 to 4.21 and the charging spending the majority of the time around .3 amps trying to bring these to balance. Should I be concerned with this or is this common? I don't recall having this issue with my other lipos before.
