Hitec/RCD 44173 LiPo Voltage Checker and Equalizer

Plug it in and in one glance you'll see how much battery % is left and the individual cell voltages. If your battery is unbalanced, after 5 seconds it starts balancing you pack automatically. No fuss, no muss, only what you need in a unit that fits in your pocket.

This is the third voltage reader I've purchased and the only one that can balance the cells. I purchased it because I needed a way to measure the voltage of my 2 cell and small 3 cell batteries. This is the best tool for this purpose. It gives the voltage of each cell simultaneously and also will balance them if you allow it. Best of all I can read the voltage of all but my single cell batteries. I recommend this device to anyone looking for a voltage and balance meter for LiPo batteries.
