What does your battery manual say for charging recommendations? What brand batteries?
AGM need careful attention to state of charge and regularly achieving full charge or you can give them an early death by walking down the state of charge. The key to SOC is charge current acceptance at a specified voltage. It’s not as simple as sticking a hydrometer in an open cell battery.
If those are Lifeline brand for example, 60 amps or so would be the minimum recommended charge current and the full charge when it tapers to about 1.5 amps at 14.4 volts.
