issue was the solar panel controller sending too much charge to battery’s

Some solar controllers need connecting in a definite sequence. Battery first, then solar panels. The solar controller automatically recognises the battery voltage as 12V or 24V, and sets up the charger voltages.

If not in that order, the controller can get a high voltage of say 24V from the panels, feeding through to the battery terminals which have no battery connected. The controller registers that 24V as the voltage of a 24V battery, and sets up the charging voltages. Then when a 12V battery is connected, it overcharges.

So try disconnecting the panel input, and the battery output. Then connect in the correct order, battery first, then panels.
