How can you tell if a lipo battery is fully charged. I bought a Turnigy Accul-6 50W 6A Battery Charger. I hooked it up to the proper port on the charger and got all kinds of readings except what I wanted to know, and that is, the state of charge the battery is in. When i put it into my trans. it showed 9.9V right out of the box, no charging or nothing. I then tried it out on my plane and everything worked great. Its a zippy 1800 mah Transmitter battery. Do these things come fully charged, this one seemed to have. I have just recently switched to electric, so actually I know hardly anything.
