Cool. I added 48v 250ah (12kW) of Lithium Ion in the same space as (2) 6v 230ah batteries. Adding the solar next year. Mine works now so that if we are on 50a they batteries just ensure clean power. If on 30a, then the batteries add the extra back up to 50a. If boondocking then the batteries run it all. Anyway, love seeing people upgrading. Yes I built my batteries, put the neighborhood kids to good use. Only vaporized 2 of them, luckily both from large families.
