I like ceramic heaters for stress testing.
A ceramic heater is ~1440 watts ac which works out to ~66 amps dc on a 24 volt nominal system.
If that load doesn't show any hot spots after an hour add a second one.
2 of them is ~132 amps dc.
Make sure you are not driving either bms over its rating of 100 amps.
See if the current flow gets more equitable or less with higher loads.
Because I don’t know what I’m doing. Lol.
The one set is for driving the 12v side of the RV. The other set goes to the generator. To be honest, I don’t know why that’s needed other than it was attached to my old battery. I assume it’s to start the generator. Don’t quote me on that though.

I just hooked up the AC Input to the MPP and the low battery is charging. I’ll let it go as long as I can and then shut the batteries off for the week while I’m gone and just let the RV fridge be powered by the AC power. Maybe I just need to get the SOC closer and then they’ll stay together. At least I know I did a good top balance and then rearranged the cells to like capacity and then paralleled the sets. So I think it’ll be good, but like I said, I don’t know what I’m doing. ?
