Display is useless for me, because I built it in the battery, covered everything in silicone.
I use the app via bt and it works fine.
I bought a 15A 50V charger from ali. Charging time is about 2-2.5h for 50Ah 12S.
@Rienk@jezypeti is there anything special required in the charger you use, or just a normal CC charger and this BMS takes care of balancing and end of charge disconnect?
It takes care of your battery. You don’t need anything else than a charger. If you use for discharge, it don’t let your battery fully empty, or discharge more than you setup in the app. You can setup your balance voltage too. Mine starts balancing at 4V and balances the cells to 0,005V difference between cells, and stops chargeing at 4,1V.
