DALY 24V BMS li-ion 7S 120A with Balance Wire and Temperature Sensor for Rated 3.7V Lithium Battery Power Bank Short Circuit Protection（Standard BMS,120A Fan）

I use this on a 24V Li battery pack and it does well in protecting the pack. It shuts off as the pack comes up and shuts off as the battery is discharged. I use the battery to run my 24V refrigerator and the system works nicely.

This is probably the best bms I’ve used; every one works without issues the first time installed

I had ordered a early model of this that I could not get working, reordered and it is day and night compared to the first one, I am only using it for the balancing feature and I set it at .2 amps and it's working on the first day:) the new app and wifi dongle only work with newer versions of Android. I will update to the full five stars if it is still working great a few months from now.. these balancing products were notorious for being a rip off early on,this one improved.glad I gave it a second chance!

It works as expected I use it as a charge and discharge bms and it seems to do well.

I built a new 7S pack put the bms on it started the charger cam back a little while latter and the pack was at 32 volts, so much for over voltage protection.

We had issues they promised to help and they did Rainbow was very helpful better than the rest she a girl with will work hard to help you why made everything better it did take a long time and energy but it was fun I will be a repeat customer thanks for your help Rainbow 🌈

These work very well. Testing them on some batteries 18650s 7s. I'm using them to make a few battery banks for electric scooters and they are working very well. They definitely maintain a nice steady millivolts for each cell group. I'm getting roughly around 3 to 6 millivolts of difference in cell groups which is really good. Discharging and charging has been working fine. Very easy to work with and I do like the design. I have bought four of them. Highly recommend.

Built 2 18650 battery packs using these for BMS. Would prefer the wires were a larger gauge or solder my own wires on it. For a 24v battery and these are 20 amps for a 3 meter run (to load and back) 8 gauge wire is recommended and this is around 14 but silicone insulation, so it looks silly to have this connected inline with 8 gauge wire.
