Review on 2-Piece Battery Meter Monitor: Low Voltage Buzzer Alarm, Digital Capacity Tester for 10-100V Batteries - Golf Cart Voltage & Temperature Monitor by Chris Nako

I have two BCP rides on vehicles. I upgraded the batteries in them to a higher capacity. I needed something with a battery indicator to show when the charge is getting low. This does exactly what I need. Comes with a built in temperature sensor (which only reads in Celsius) which I plug into the control box for one or rider and into the battery box for the other. If I start increasing the voltage on both, the temp sensor will come in handy. On the negative side, one of the wires on one of the wiring harnesses got mixed up which made it not turn on. After replacing the cable, it works perfectly. The second disadvantage is that the battery signal is very loud on one and not very loud on the other.
