This simple to use Lipo Battery Checker displays the voltage of each cell of a Lithium Polymer battery. No more wondering if you remembered to charge that battery -- with this handy little gadget, you'll know in a few seconds. We use one of these every day to check the individual cell voltage of every Lipo battery that we ship!

To use, simply insert the prongs of the Battery Checker into the balance plug of your Lipo, and the voltage of each cell flashes in sequence, followed by the total voltage of the battery.  The sequence repeats about every 5 seconds until the tester is unplugged.

This Battery Checker can be used on any size Lipo battery packs with up to 6 cells, as long as the battery has a JST/XH balance plug. Please read the 'Specifications' section below to see which brand of Lipos are compatible with this Lipo Battery Tester.  There's no need to worry about plugging in a Lipo battery incorrectly. This Tester has reverse polarity protection built in, so you can't hurt it by plugging in 'wrong'.

Remember, a fully charged Lipo cell is about 4.20 volts, and Lipo cells should not be charged higher than 4.25 volts, or allowed to drop below 3.0 volts
