|  voltage comparison between each cell
I always wondered. How much difference does each cell of each battery have. I always use a lipo voltage checker on my battery and none of them equals the same. Its either its off by .02 or .01 up to .04 is the greatest. So my question is how about your batteries are they off too or they all equal the same on each cell. My batteries are fine they last as long the other batteries when I play with other people but i never bothered to ask them if I can check their voltage. |

What voltage checker are you using? in all likelyhood your instrument doesn't have the accuracy to say that .04v difference is meaningful. I would be worried at .1v, depending on where in the state of charge you were when testing. A mostly discharged pack have more variation than a pack at half charge.

Some voltage checker a friend gave me and today I was looking for it somehow I cant find the little thing. I used it for heli's because it also had an alarm to it. | |

0.01v is pretty darn close to SFA. Anything smaller than 1/10th of a Volt really is theoretical when it comes to batteries IMO.

I wouldn't call it theoretical, but I would say that measuring 0.01v accurately is difficult on a multi channel device.

So that means my batteries are on the safe side right? It really doesnt bother me at all and has nothing to do with its performance. Its overall and great battery. |

Yeah nothing to worry about - now go on and let it rip!  |

Like John mentioned many of the little portable voltage readers aren't crazy accurate. My little led checker is generally of by up to .05v per cell compared to my charger. They definitely aren't prefect but help when trying to get an idea of where your batteries are at mid run.
