I needed a new battery for my RC Phantom, and have been looking for something that would also allow me to see how much juice the battery had so I would be able to tell BEFORE I took it out to play with it. The batteries don't have a very long life, so if I start with the battery only half full, I'm lucky to get 5-10 min out of it before it's dead. This LiPo Battery comes with a voltage meter so I simply plug it right into the white connection end of one of the battery cables, and it tells me instantly how much battery life it has left, I Love it! It also helps tremendously in preventing me from over charging the battery, which eventually shortens the life span of the battery all together.
So I found everything I was looking for with this kit. The battery I needed to replace my old one, and the voltage and battery tester so I can check how much battery power is left any time I want to, it's perfect. I can't think of anything that would makes this set any better for the price. They really thought it through when putting this kit together, and I'm very grateful. Great job.
