It works as advertised. Measures the voltage of each cell and summary with good accuracy. It's cheap and lightweight. Great product for the price! Allows me to check my lipo batteries' voltage on the fly and also make sure I have them at the right voltage for storage. The polarity markings are so small I don't even bother to strain my eyes to see it.... Read more
This little gadget does exactly what it says on the site. It's super easy to use. It's small enough to easily fit into your toolbox without taking up too much space. I really like how when you've connected your battery to it that it shows the voltage in each of the cells, this is useful to know if you need to balance your battery or just to keep an ... Read more
The LED display is bright enough to see in sunny day. It measures and displays every cell's voltage separately, then shows you the whole battery pack voltage. It also seems to have a opposite power protection (judging by the diode on the 4th pin), but I haven't tried that yet. THE PRICE - unbeatable for such a cool gadget...I'm totally sold :) None....

A little voltmeter to check the batteries. I don't have to carry my multimeter. It's display is bright and big. I don't find any cons. It doesn't have any manual but I think you can find a correct connecting diagram on the web. I use it to chek the batteries' voltage in my pack.

Works as expected.
Shows voltage of each serial connected cells and of total battery.
Tiny - will be permanently attached to the battery when in use.
Easy to read display. - no serious being observed - Display is multiplexed and hereby flashing at ca. 20 Hz. The slow-multiplexing is making attracttive eye-catching effect for my use (being decorative ... Read more
Quickly allows you to check the the voltage of your lithium polymer batteries in the field. prevents the mix up of charged and uncharged batterys. it shows each cell to two decimal places Cycles through the cells quite quickly but doesn't really matter because it repeats indefinitely. It is not very easy to see in bright sunlight. Will probably have ... Read more
A very good product for voltage info of two or more batteries connected. Quite simple design, fits allmost anywhere.
Welding and parts quite good, works straight from the package. No schematics, no pinout guide. If used with only one battery, gives false information of over 2v, so works only if 2 or more batteries connected.
No knowledge of the manufacturer ... Read more
These are very useful when checking LiPo batteries, during charging and usage. They are very accurate, at least in my case. I bought 8 and they all worked well. It would be good to have the polarity more obvious. It is tiny and unless I look closely (esp in poorer light) I end up guessing. There are three wrong ways and only one right one. :) You can'...

Excellent product! The instrument is doing its job very well, and I've tried.
A few seconds, and read from the cell info! There is nothing negative that I can write ...
Maybe is that I did not get a description of the treatment, but did not cause any particular problems of using :) Thank you...
I'm glad I found this product .... We highly recommend ... Read more
Easy to understand how to use
Bright display (LED) Too small letters on connector pins description, but it is in fact needed only when you use it first time. Need 4 tries in worst cat to find how to connect battery to it, before i found that polarization is marked on PCB (pretty small letters, about 1mm height or so). Also some kind of beeper ...
