My charger is a racing star RS16 (but I don't have a 12v battery yet so can't use it)
My sons charger is a etronix powerpal
Lipos are Core-RC 4000mAh. 1C saddle packs
I thought I had it set correctly on my sons charger (set to "Lipo --> balance --> 4A --> 2s", and then I was wired as follows: -
cells linked with a single black lead +ve on one to -ve on other. I then had balance lead connected to 2s socket and plugged into charger, I then connected the charging leads with the red lead going to +ve on 1cell and the black to -ve on other. When I tried to start charging it "connection error".
