hi there, thanks for a great forum, I have following from the sidelines for a long time, and only registered to post now.
My question is around UPS units and Batteries.
I have 2x 120AH Deep cycle batteries.
Due to the current load shedding woes, I am battling to find another 120AH , so that I can build a complete 48V system.
Could I use 2x100AH or 2x135AH batteries instead?
