Mixing AGM and Flooded Cell Batteries
Hi I tried posting this question earlier today but it apparently did not go through. I have a mobile hotspot and in some locations the data transmission is spotty. Any way, here is my question. My...

It will charge. I paralleled 1 flooded starter with 3 coach AGM because starter one was dying and didn't charge well on its own.
The combo of 3 AGM + 1 starter behaved normal, charging and floating. I didn't try cycling it too much, my goal was merely to restore the wet cell and charge it fully.
I only have a tiny 175W inverter that is used an hour or two a day and only when batteries are floating.
I don't think the starter batt - no matter if it's an AGM - will enjoy deep cycling if forced to do so due to being parallel to coach batts.
Also, voltages will be averaged between AGM and flooded, so your setpoints will be screwed up a little. Trik-L-Start may help with this, didn't try it.
Equalization of a wet cell is a separate issue, this will likely require disconnecting the flooded from all the loads and from AGM.
