Thanks for the reply.
Yes I have checked, rechecked, double checked, checked until I can check no more the polarity of the charging cable and there is no problem there.
I really don't care to use the DJI charger anyway and so I would like to find out why I'm getting an open circuit error when...
I have two of the Phantom branded 2200 batteries that came with my Phantom.
For all my other planes and 'copters where I use 2200 batteries, I use a Triton Jr with an Equinox LiPo cell balancer to charge. My other 2200 packs are all Zippys and I have to trouble charging them.
