Great BMS. Bad App
Love the BMS, very flexible. Wish it would be constant on if the start button were removed. App is barely functional and bluetooth is weak. These are not reasons to not buy it. You only have to manage it once. They work well enough

Finally…A real BMS
If you’re looking to build your own battery pack a BMS is essential. I bought other ones from Daly (red and black) as well as Daly’s better line called 100 Balance which are blue. This BMS is WAY better and so is the APP.My biggest complaint about the Daly is that even the “active balance” is only active while charging. This one will balance the pack charging or not and it can do it at 2 amps which is much faster. The app instantly connects. The app is much more responsive to changes where the Daly had seconds of delay in showing how much current was being drawn by the motor. This one has any setting you could ever want where the Daly is much more basic. I am super happy.
