Incorrect description it only is 1A Active Balancer
Incorrect description it only has a 1A Active Balancer not 2A as advertised disappointing and misleading. Not going to be a return customer. Use another supplier as JK BMS work great

JK far superior than Daly
This is used in my camper in a 12v system. It replaces a Daly BMS that I have never been happy with. With this BMS, I now am able to fully charge my battery, and in fact, I have probably 40% more battery power available. Second, the active balancing of this BMS is far superior. Third, the Daly BMS app always asked for permissions from my phone that I did not feel comfortable giving. This app has no such problems. In summary, Daly is prettier, but the JK functions much better. I wish I bought it a couple of years ago.

Easy to set up and even has an activation switch
Just installed in an SOK 12v 206 Ah that had a bms that stopped working. So happy with this device as setup was pretty quick and directions included would get you there if you have small print read ability but the online downloads are much better. Love the settings as parameters, chemistry and readability are very good but the push button switch makes it so easy to activate.I'm building a new 1200a 12 volt bank and will use more of this type but 100ah
