It is designed to measure the individual and total voltage of a multi-cell battery pack (that is, the cells are connected in series). It supports up to 6 cells, and displays each's one's voltage with decent accuracy. It appears that my module doesn't measure AA (R06) battery cells (that is, under 1.5V per cell), thus requiring me to connect the test ... Read more
Nice small tester for my Lipo batteries. Very large numbers. Tester is so small and light that I left it connected in my glider for some flights. You have to be carefull when conneting battery so you don\t change sides. There could be some identifier. I use this tester often when I fly my models. Need to have ot, so I don't drain my baterries too much.... Read more
I build my own battery packs from old packs.
I use this item to read voltage on multi cell packs to check balance while in use. I also build my charging cable so item will connect to charger cable while charging batteries to verify balance during charge. Item agrees with several of my volt meters. I prefer the item on multi cell packs as it makes reading ... Read more
Muito eficiente esse dispositivo , serve para ser usado em campo de voo para aeromodelismo que é por esse motivo que comprei , nesse caso nao preicsa ligar o carregador e muito menos multimetro para se medir as celulas Sem contras Produto chegou muito rápido e muito bem embalado Muito útil, precisa o suficiente para tomar uma decis...

Works great, it's very bright even in bright light.
Shows cell voltage first (first cell, second cell, etc.) and total voltage last. It uses battery power, but since is use only for battery check, it's not a big deal.
Be careful that it only works with a minimum of 2 cells , and a maximum of 6 cells , but can measure more then 6 cells, just not all ... Read more
Very light and small, good for RC helicopter use. I use it for bicycle lighting system. So I don't drain the battery too much . Beep is very loud so you can hear it in traffic well. simple mounting Beeps evry time when you plug it in . anoying Simple plastic shrink tube around . Plug from battery can be mounted in 2 ways, but only one way works . Difficult ... Read more
Not to shabby multi cell voltmeter that's easy to use and very visible even in daylight outside. Very easy to use, and can keep you from flying with a non fully charged battery. Not very accurate on the individual cell readings The tester reads each cell individually and then gives you a working cell count total voltage reading.
The unit was cheap and ... Read more
It's a multi-channel very cheap and tiny voltmeter.
LED display is bright enough, build quality is very good. It is not precise, with pin 2 open it told me there is a 0.05V
You have to connect pin 3 to + of a battery or a power supply to get device working.
The most important is that no firmware upgrade available. You can't change the speed of indication ... Read more
Very easy to use, and very handy out on the field especially if using for air or sea vehicles in making the decision to use a battery or not before flying or boating. I find the more cells a battery has the more inaccurate the unit becomes (reading higher than the actual voltage). Cell one's reading being the most accurate (within about 0.03volts) and ...
