Hi Everyone, my first post, i hope you can help. In my van I have 2x 110ah leisure batteries wired in parallel and bought the IP22 30a 3 output charger my question is which is the right way to connect it to the battery bank. 1- only use one of the three outputs to charge both batteries as they are in parallel or to use two outputs one to each of the batteries? Also can the negative from the charger go to the main negative bus bar connected to the batteries negative and ground to the chassis. Hope that's clear enough.
