Note: These are only compatible with our 100amp & 200amp Smart BMS. The 300a Smart BMS already has this installed. They will not work with the 30amp standard BMS. Use the Xiaoxiang App to integrate to our BMS units via bluetooth. There are some connection issues mainly with certain Android phones which we are hoping to clear up in the future. You do not need the bluetooth device to get the BMS units to work. They are already optimized and programmed for low temperature disconnect with the above parameters already set. With this bluetooth device the apps work on some phones and not on others. It seems to work best on Iphones but not so much on android. It is sort of hit or miss right now. The BMS needs to be powered up to activate the bluetooth module. The issue we have with android is some phone bluetooth settings block the app. If you are good with phones I'm sure you can figure it out. You can adjust all the parameters, over charge, over discharge, low temp cutoff, etc directly from your smart phone. We can't give technical support for the bluetooth device. This plugs right into the Smart 100a BMS units that we sell. -------------------------- Apple App: click here -------------------------Android phone app download link below click here --------------------------
