Hi,
I'm keen on fitting the above to combine two battery banks BUT my motorhome charger unit is already near the max of its capacity i.e. 200amps. I'm not sure how many amps power the combiner allows to cross the relay or whether the charging unit will exceed its design if a link the banks in this way. Will the charging unit still only work within its design limits ie still think its connected to a smaller bank and the residue current will just go through the combiner to the new bank or will the charger have to supply additional current to its design parameters.
