How to connect your batteries optimally
Charging should preferably go diagonally through the battery bank, that is, plus to the first battery and minus to the last battery in the bank.
This way you charge the batteries as evenly as possible. Consumption also goes diagonally through the battery bank. This will be easier if the battery bank is assembled in one place.
In a parallel connection, each battery itself limits its charge through its resistance. All chargers like generator and solar panel will be charging, preferably at the same time. Check that the voltage does not exceed the battery recommendations.
A rule of thumb is never to exceed 14.4 V to avoid overcharging.
