If the batteries have the different capacities the charging current will have to be set according to the battery having the least capacity. This would both retard and complicate the charging. (i) During the charging period the temperature of the electrolyte should not exceed beyond 40 to 45 °C because of the danger of plate buckling.
In this case source of current should have a voltage of 7.5, 15 or 30 V; these batteries are connected in parallel to the charging circuit. The convenience of charging at constant voltage is that it allows cells with different capacities and at different degrees of discharge to be charged.
Let’s suppose you have 3 different 12V batteries, wired in parallel to supply 12V power to your RV. They can have different capacities on account of size or age, but the same chemistry (e.g. all flooded lead acid or all AGM). Before you start charging, the voltage across each of them is the same–even if one is fully charged and the others aren’t.
Charging at constant voltage may be carried out only when the batteries have the same voltage, for example, 6 or 12 or 24 V. In this case source of current should have a voltage of 7.5, 15 or 30 V; these batteries are connected in parallel to the charging circuit.
In this method of charging of batteries, the batteries are connected in series so as to form groups and each group is charged from the dc supply mains through loading rheostats. The number of batteries in each group depends on the charging circuit voltage which should not be less than 2.7 V per cell.
With a lead acid battery bank, the internal resistances are limiting to a point that you don’t have to worry about arcing or your battery cables overheating when you connect them (not the case with lithium-ion banks…). So when we start charging, all of the battery banks are very close to the same point as far as state of charge.

There are two ways to wire batteries together, parallel and series. The illustration below show how these wiring variations can produce different voltage and amp hour outputs. In the graphics we''ve used sealed lead acid batteries but the concepts of how units are connected is true of all battery types.

Those of you with lead-acid batteries may have noticed that the manufacturer advises not to discharge the battery below 50% of its full capacity to improve its life duration. In lead-acid batteries, over-discharging creates parasite reactions (sulfation) at the electrodes, slowly damaging the system.

On the contrary, to generate the same voltage level, 5-6 cell of lead-acid batteries, each having a capacity of 2.30-2.35V is required to be connected in series. A higher cell voltage makes LiFePO4 batteries a practical replacement for lead-acid batteries in the automotive and solar applications. Lesser …
When connecting batteries in parallel, you should ensure that the voltage of both batteries is the same. If you connect batteries with different voltages, it could lead to issues like overheating, leakage, or explosions. Therefore, it is not safe to charge two batteries with different voltages in parallel.
