Batteries should be separated after the charging protocol. Connect all batteries together and apply 1 nominal 14.2 charging volts and there is no way any of the batteries can detect it one battery or a hundred are online, or the chemistry of any of them. The only requirement made of a charging system is that it not under or overcharge the battery. Voltage requiments for flooded 5% antimony batteries and pure lead AGM is similar enough for multiple warhead work.
It's when the charging ceases that the problems arise.
So go ahead and use a smart solenoid to parallel charge the batteries. I have done this too many times to count.

Here's a tip to understand the reality of same type of battery has different chemical attributes according to its state of charge or age.
Fully charge all batteries
Wait 4 or 5 days, then measure the voltage potential of each battery
Take a hydrometer reading then reconcile it to voltage of each battery.
A tenth of a volt is significant, two tenths is worrysome when you are trying to balance batteries.
To amplify the test, apply 14.8 volts after fully charging the batteries. Note that the cells with the lowest gravity and lowest initial voltage boil first.
Cells that droop after charging, actually CONSUME power. Roaches check in but they don't check out, time. The worse the cell the hungrier they get. Some are the eqvt of a 20 watt load on the other cells in the bank.

Quoting Mex "It's when the charging ceases that the problems arise." I get charge them together and then disconnect them from one another after charged!!!!
