Works okay
Works okay just will not let the battery charge to this full capacity shuts off around 52.4 instead of 54.6 other than that it works just fine. I tested all my cells and found that they where out of balance 1/2 of them where 3.8V and the 1/2 where 4V so I charged each set of 4p cells to 4.1v and then finished charging the back to 54.6 v throw the BMS. I am runing it now on my ebike win it gets down and needs charged I will test all the cells backe and see where they are and then if there all the same I will recharge it and see what happens.

Brought my Battery back to life.
Bought a cheap eBay 48 volt 20amp hour battery a couple years ago. When I went to charge it up recently I got nothing. No charging, no voltage. The BMS was shot. Swapped it out for this DALY BMS and now it works great!

Solid build quality
I like most things about this BMS. It is safe, it handles 30a like stated, it is built like a tank. My only negative is it doesn't have an on off switch solder point. When I make a battery in Hailong or Polly cases, I like to have the built in switch funtionality.

Doesn't work
I chose to not believe some of the bad reviews here, and ended up purchasing this BMS. What a mistake that was! My device never worked, and I wasted a lot of time on it: 1) the bluetooth UART worked inconsistently, and the app NEVER showed any data even when connected. 2) the USB UART worked inconsistently with the desktop application: it showed cell voltages, but would never allow settings to be changed 3) the BMS's contactors were always open: I could NOT charge or discharge the battery Customer support is completely non-helpful. They will tell you to try things that are not even applicable to this model. For example: - Support: "did you try activating it?" - Me: "the manual says you activate it by charging or discharging, but that's what's not working right now" I see that a lot of the reviews here are positive, but I also see that some reviews have similar situations to mine. If I had to guess, there is probably a high failure rate here, or maybe they are re-selling the known-defective returned units. Very disappointed.

Daly Quality via Amazon? Maybe.
Many Daly BMS that I've bought on ebay of thru aliexpress don;t appear to be real. This one looks legit, and came really quick too. Now on it's 3rd charge cycle. It seems to be working well.
