No one uses diodes on their battery banks, lead acid can tolerate some overcharge which is how they are equalized and lithium use a BMS for balancing cells. The only diodes I have seen are used for Chassis/House bank isolation but usually its a relay system instead. Remember a 12v lead acid battery is 6 cells in a single package no different than two 6v batteries in series (which is what my RV has).
