HItec has some of the coolest gadgets and this pocket sized "Lipo Checker" does a bit more than just check Lipos!
So many times I've been at the track surrounded by rounds of batteries and a couple of them on chargers, then you wonder.......wait...has this one been charged? I don't remember charging this one......That's where the Lipo checker comes in! The Lipo Checker was designed to be powered by the Lipo and take a voltage reading from each cell of the Lipo (up to 6 cell) and an overall percentage of charge. Then, if left plugged in, the balancing function kicks in lowering the higher voltaged cells to the same as the lowest reading, balancing your Lipo! That's cool!
Here's a link to Hitec with some info:
Product Description
The Hitec LiPo Checker has arrived and you are going to love it! With an easy-to-read LCD display and built-in safety features, the convenience and accuracy of this tool can't be beat. The battery checking function precisely reviews the voltage of each cell of a lithium polymer pack while displaying the remaining total capacity. The balance operation equalizes the individual voltages of each cell until the difference between each reaches 0.01 volts or less. Although most LiPo packs' balancing ports will plug directly into the LiPo Checker, we also included an adapter for Thunder Power and Flight Power style plugs. Please be certain to use lithium polymer battery packs up to 6 cells only.
Here's where I got it:
