I have the same battery plan, if I need to I guess. I have a PD 40amp charger and it's not programmable. Maybe others are but I didn't find that when I was shopping, seems most are just 14V power supply with a remote shut off. I have my victron wired to control it and the shunt shows the battery taking 40a from it. I figured it's really not an issue running the gen an extra few minutes than hurting the battery. Just verify that on which ever battery you choose.
I did run this battery to 0 once to test it, the bms disconnected. I was able to charge it fully in just over 2 hours....
