I have 4 house batteries that are also used as starting batteries on my boat. It was wired this way from the factory.
Recently I replaced my flooded cell batteries with AGM's that have an Ah of 66/hr. Run in a parallel this gives me a theoretical 264Ah.
Is it possible to add a third battery of the same voltage but with a higher Ah (8D maybe) to this parallel to increase my house bank Ah?
I'm leaning towards it not being possible as they would discharge at different rates but wanted to double check my math.
