CAMWAY 5PCS 2in1 1-8s Lipo Battery Voltage Tester,RC Low Voltage Buzzer Alarm,Battery Monitor Checker Tester for 1-8s Lipo/Li-ion/LiMn/Li-Fe

Very happy with product. Works just like it says. Should have bought these a lone time ago. A must have for RC pilots.

Exactly what I needed for my batteries!! And came with multiple!! Great deal!!

There are five testers in the package

So far so good in testing only, have not used in 22.2v 6s 6500mah 90mm EDF yet to see what happens with voltage pull at high throttle. Not sure if high throttle will drop voltage below alarm and if so will alarm stay on until disconnected. However, the voltages measured on this little sucker across each of the cells and the total voltage measured was spot on when checked with a good battery monitor that I use to measure battery v%. Only opened 2 of the 5 and both were pretty accurate. Very easy to change voltage limit by pressing button from 2.2v to 3.8v. Definitely not waterproof although they are shrinkwrapped but not 100%. But hey getting 5 for $10 if it craps our swap it out. Very light weight, loud beeps, roughly size of a 4-6ch receiver....only reason not 5 star is for not putting it through a flight yet.

This type of device is very useful to track battery voltage precisely. It provides a clear, audible alarm when battery voltage drops to your preset value. I can personally vouch that you can hear it in a model that is at 200 feet or more away (up or downgrade). It provides me the security I want to be able to keep on flying when I would normally land “just in case”. I know that when the battery is low I’ll hear it and have enough reserve to land safely. Not just for aircraft though, I use them in my surface vehicles as well. I understand secondhand That they are useful in boats. I drive rock crawlers, And the runtime is long enough that it’s easy to forget to check voltage and damage of battery. A lot of people sell these devices. I’ve bought from several different vendors and never noticed a difference in quality, or even an appearance. These are certainly as good as any I’ve tried. I recommend them for any of the above uses, or similar.

Just as advertised.

These work as described same functionality as the expensive ones

They worked as described!!! very happy!!!

Merci au top

Good little product at a great price. Works perfectly in my rc planes.

This voltage meter gives precise measurements of lithium polymer battery cell voltage. The adjustable alarm is very useful especially on RC helicopters. It keeps you from having to guess how much voltage is left and prevents crashes from over estimating the amount of energy remaining in the battery. Great product.

Funziona bene.
