Sacman said:The "battery connection error" doesn't come up if your power supply is too small. If it charges your 6s packs fine it should charge your 12s packs too but just at half the amps. Remember these 1420i chargers were made for use largely by the RC guys who power their chargers with their 12v car batteries while they are out in the field flying their RC planes and helicopters.fractal said:so i tried charging at 12s. everything is plugged in perfectly but i get a battery connection error. the input voltage is 13 volts. is it possible that its too low for 12s. the manual dosent say shit!!!! (tried charging eac 6s packs separately and it works)
I think something is still wrong with your connections when you series charge your two 6s packs. Can you take a pic and post it up?
The easiest way I can tell people to make the connections correct is to make sure pin #1 on port A (black wire) is connected to the same battery pack that also connects to the thick black (-) charge lead.
ok ill do that, but i can confirm that that is the way i plugged it. thanks for all the help!!!!
