I'm a data nerd and added the Bluetooth module to my Ryobi ZT480e that I converted to the 60ah 48v battery kit. I like seeing the battery health, battery temp, cell voltage, and all the data you get in the Epoch Pro app. I got mine wired up on the opposite end of the canbus from the fuel gauge the battery kit came with, with a resistor connected to the gauge side of the module. That way the gauge still shuts off after the 12 hours of inactivity. You can still pull data from the Bluetooth module at anytime. Kinda cool to watch the batteries charge from my phone. Only downside is the readings in the app over Bluetooth has a second or two delay versus the gauge, but I'm not surprised, it's the nature of Bluetooth.
