IP65 12V/15A blue smart charger with AGM battery bank

I have the IP65 12V/15A blue smart charger and would like to use it to charge a bank of two Optima D27 AGM batteries 66Ah each. (Wired in parallel)

Is it ok to use the single IP65 to charge both batteries by connecting it to positive of one battery and negative of the other.

Thank you

If the batteries are the same age and same state of health, then yes, you can connect them in series and charge them both as a 12V battery bank.
They would also need to be the same state of charge before charging them in series otherwise one would reach full charge before the other one and end up being overcharged.
