🔋 Comimark 2Pcs BX100 Lipo Battery Voltage Tester with Low-Voltage Buzzer Alarm - Effective Monitoring Solution for Li-ion Batteries Review

Thanks to my knowledge gained in practice, I know how important it is to keep track of the voltage in my devices. This monitor has been an absolute lifesaver - I love how easy it is to install and use. It's compact, yet powerful, and it's helped me prevent any low-voltage issues with my single board computers. The only downside? It doesn't work with every type of battery, but that's a small price to pay for such an essential tool.

They look good and the offset works quite well. My problem with them is that at almost 2 volts (common voltage) the alarm in my RC goes off earlier than it should. Even when the alarm was set at 5.4 volts (2.7 volts per cell), the alarm went off at almost 7.2 volts (3.6 volts per cell). I wouldn't want to go below 3.4 or 3.5 volts per cell anyway, but setting it to 2.7 volts is a bit annoying. I have to keep an eye on this and can set the alarm where I can see it well, but the problem is that…

Supplied individually wrapped in anti-static bags filled with a large but small black plastic bag. Came with white and black, both of them perfectly match my 3S 5200MAH POVWAY LiPo, 10/10 works great
