What I see now is:
1. You have an extra panel that you would like to use to charge an elect OB battery?
2. This OB battery system seems to have a 12v cig plug
option to charge?
3. You want to connect a 12v cig socket to the panel
If this is correct then all you need to do is regulate the voltage output of the panel so you don't blow your 12v charging pigtail to the OB battery... The charging regulator
is all built into the OB batt???
