Review: Easy to install, works right away, nice interface - Got this on 2 of my lithium battery banks. Works really well, easy to access over WiFi and/or Bluetooth. The version I got came with the WiFi and I added the Bluetooth adapter that came with the separate balancer. Together they work seemlessly and are doing exactly as they should be doing.
Review: Works good - Out of 5 only ine had a problem and it was quickly replaced..

### ⭐⭐⭐⭐⭐ Works good

Out of 5 only ine had a problem and it was quickly replaced..

### ⭐⭐⭐⭐ not bad, not bad at all
*by K***K on August 26, 2024*

i got 4 of these to maintain 4 banks of 320ah lifepo cells, 16 total, 4 per pack. it was very aggrivating trying to install these with little to no documentation, yea, there's videos but they dont really go into much detail. to all buyers, know this, "THEY WILL NOT ACTIVATE UNTIL YOU PUT A CHARGE TO THEM. this does not matter if your cells are pre-charged for storage or not. once there is a push to them through the bms, they will come alive. however, without putting a charge to the bms/battery bank, they will NEVER come online, and they will NEVER be seen by the APP. it was very aggrivating that i couldnt check the bank before connecting it to my system. i had to build the bank, and hope for the best then connect it up and attempt a charge.. before i could even see the bms.. which sucks from an engineering standpoint. also keep in mind, these bms do get hot, they do not have a built in cooling fan..something to consider.. they maybe only 100 amp, but they do get hot when they are pushed to 80-90 amps.. otherwise, once they are up and running, they do pretty good. i've had them on a 43 foot sailboat behind a victron 3k-watt inverter, and they doing great.. just wish they would make it do MPPT modbus over tcp.. its a basic protocol, so i dont know why they dont do it. it would also help if the wireless module wasn't just bluetooth. so i'm building a esp32 gateway to convert ra485 to mppt modbus so that i can read them with my victron cerebro gx. will buy them again if i ever build another cell bank..
