I'm charging (or trying to) completely flat NiMh batteries.
They're 10S, so 10 pieces of 1.2v in series, 12v.
I have new banana plugs and they look just fine. Hook them up, set it up to NiMh 10S and press charge.
The voltage increases from 1.6 or so to 2.7 and then I get the "Connect error, check main port" message.
It was charging, so why do I get this error? Doesn't it understand flat batteries or am I doing something wrong?
