In order to charge your batteries wired in parallel with the NoCo Genius # 329-GENIUS5 you'll want to connect the positive charge line to the positive terminal of the first battery and the negative line to the negative terminal of the opposite battery. This is an AC to DC charger so it will work directly from a wall outlet for added convenience.
