BAT-T-10 LiPo Battery Tester & Low Voltage Buzzer 1S to 8S
If you ever wanted to find out what the voltage was on your LiPo battery, this little device can measure the voltage and readout the value to indicate when the voltage for a cell is past a setting that you may have set it to. LiPo batteries are happy around 3.7v to 3.2v any lower and it can often never recharge again, any higher and it could be affected by reducing the lifespan of the battery. The speaker will sound when the voltage is too low, offering a reminder to charge the battery. On the back of the unit you can see instruction manual for configuring the low voltage range.
Always plug the black wire into – as the starting point. It builds from there to 1s,2s all the way to 8s. So you could test a 8 cell or 8S battery.
