The BMS I just spent 3x as much on to not have all the spyware issues. Daly want me to log into google and allow location service. This one has a detachable Bluetooth / WiFi module. The main bonus is the touchscreen display that can program it. Currently many devices monitor near by devices.

If you ever build a battery for solar or what ever keep this in mind. Never buy jk BMS if you are building a battery. The jk bms. Require the instantiation of spy ware. The app will not work without access to your GPS forever. Also they constantly transmit a bluetooth signal. Blue tooth tracking is becoming more and more popular. Newer cars log Bluetooth ids and location as do smart phone. #solar
