Do you have a selector switch (off-1-2-both) on each bank or are the two batteries
If you are using a switch the charging
source can go to that. If they are in a single
permanent bank then you need to bring the cables
The XC5012, which I also have, switches between banks as it charges. It will charge bank 1 (my house bank) then switch to bank 2 (my starting bank). It does allow you to have different profiles for each bank, some do not. It also has separate temperature sensors for each bank.
The XC5012 is probably more charger than you need for group 24 batteries
, they do have a XC3012 as well.
