Hi, firstly thanks to all the developers and contributors to the TSDZ2 OSF, much appreciated! I've just fitted a 36V TSDZ2 with a VLCD5, and bought a Malectrics Arduino spot welder to make my own packs from new cells. Now I'm trying to consider ALL the possibilities, and I read that the lowest voltage is 24V but wondered if it's possible to go lower? 6S would be 19-24V and physically small, I can get build 5 mile packs for about £40 each using decent new cells and 6S balance chargers are cheap. Any thoughts?
