Server Rack Batteries fit Golf Carts

[Delmar]

I would be concerned about changing BMS. It is there to protect the cells. Sure, you could put a 500A BMS in there, but then you would be drawing from the cells at 5C, which, as I understand it, is not good.

In hindsight if I were to spend more money I would buy a second SOK for 10KWh and 200A. During grid-down I also use the cart to power my 3000va UPSverter and back-feed my breaker panel.

Yeah, I bought the golf cart specific batteries a little over a year ago. Pretty sure I am $8K into those. Now, the same setup, is like $5000.

My SOK was $1100 and I picked-up myself from the seller.
