sooooo, when i build my DIY board, i was going for a 9S setup (3x 3s 5000mah lipos). mostly because of size and easy replacement since those lipos are rather cheap. little did i know that having a 9s solution comes with its own set of problems. finding a 9S BMS for example (which i found). finding a 38V charger however with at least 2A is a complete different story. i can only find 36V chargers which will charge my battery to something about 85%.
so my idea right now is, using a 24V 3A charger and use a step up converter to boost it to 38V. Using a step down converter with a ~42V charger would probably be the better idea, but im kinda in the experiment mood and want to try this. stuff should arrive tomorrow.
so would it work? did anyone ever try that?
