Thank you Mondmn70. I've been there before to test drive a class B, but not familiar with their repair service. I will call them up if needed.
UPDATE: After a lot of research, I was able to do my own rewiring of my inverter from the dishcarge side to the charge side. However, after a few tests and back/forth with Roadtrek and KS2, I definitely have a bad battery. I think RT may provide some warranty for the replacement of a reconditioned KS2 battery. However, I'm concern this is just putting a bandaid. The KS2's are the only lithiums that have 2 POS terminals - dishcarge and charge; which lends itself for mis-wiring. Second reason to move away from KS2 is the huge parasitic losses from the BMS.
I wonder if anyone has replace their KS2 batteries with another brand on their Roadtrek, ie. Relion, Renogy, Lithionics, Battle Born etc... If so would you share your new configuration? Thanks so much.
