I was thinking 4 12volt wires in series but the 48 v rack batteries seem like a better option, do you think a Powerwall is even better? So 100ah 48volt batteries is equivalent to how many AH in a 12V battery?
Much better to go with a premade 48v battery than wire your own 12v x 4. That way if you end up with serious balancing issues, you can reach out to the battery manufacturer or reseller for support. Plus the cables and fuses needed to wire four batteries isn’t cheap unless you already have them on hand.
