So I've bit the bullet and bought 70, 50ah A123 prismatic cells, so now I can build a 400ah 24v battery. Hopefully I'll get it up with a Sbms120 before winter

    Any reason to not build it as a 200ah 48v battery ?

    Yea, I use the Electrodacus sbms it's for 4-8 cells, and I never run more than 2200w and that when the dryer first starts with everything else on.
