    I have purchased these voltage testers before and they are great. letting you know how much power is in your batteries. Helps you a lot so you don't let your batteries go to low in power as this is not good for our batteries. The voltage meters are.really easy to use. Thank you Banggood team fantastic product (A1).

    One of the most important tools to have in the field. It allows you to test Lipo batteries. Informs the voltage of each cell and the total voltage (quickly and practically). It has sound alarm for low voltage of the Lipos. Very fast shipping (19 days to Brazil). Would recommend! One of the most important tools to have in the field. You to test Lipo batteries. Reports the voltage of each cell and the total voltage (quickly and conveniently). It has an audible alarm for low voltage Lipos. Very fast shipping (19 days to Brazil). I recommend!

    Pretty comfortable to see the state of multi-cell lipo batteries, I use it for FPV drones. The only thing I hit him is the beep he makes when you plug in the battery, What I do is cover it inside the hand which because it is small you can close the fist well to muffle the sound because when you check 6 or 10 batteries it is quite annoying.

    Great little tester! Tested with 1 and 2 s so far! [warning: on 2s the beep nearly blew my ears out! Super loud on mine] Tiny, light weight and effective to quickly check the charge before or after flying! Will buy again if this one should ever break! 10/10

    Awesome little voltage checker. The buzzer is super loud too. I mostly use it for checking my 1s batteries since it doesn't require any other power source to operate. It's very small, so I keep it in my battery bag. The voltage reading is accurate and reliable. Unfortunately due to how the display works, I can't get a good picture of it because it constantly flashes in segments. It doesn't look like that in person.

    All right, indispensable I didn't have it and I was lost, now I'll know at all times how this every cell is.

    Ecxelent battery tester, necessary for anything to know how the cells of the lipo are, used for example in all facets of radio control. I take little time to send
