Installed 3rd SOK 206Ah 12V battery

Got my new SOK in and charged it up last night. Dropped it in the RV today to do some load testing. All went well. There's room for a 4th and I made the cables all equal length so a fourth can go in.


With one 15k BTU aircon + the fireplace on high (weird combo, right?) I was pulling 320A from the three batteries. Let it run for 10 minutes. Only thing that got above ambient temperature was the 400A type T fuse. It was at 106 def F when I stopped. All other components were ambient.


I turned the panels on. Full overcast and raining at 1:37pm in Ohio when I started. Not too bad.


Then the sun popped out. Nearly maxing my two 100/50 MPPT's capability. Yeah!


Love that 9W idle load on the MPII.

Nice setup.

Are you going to have any method to individually shut off / breaker / fuse each battery ?

They go to a Lynx distributor you can see at the bottom of the pic. Fused in that. But can’t turn them off individually except through the bms bt app.
