Status: offline 		Hi Guys, I just bought an Art Tech Jet Tiger EDF. This is my first time using a Lipo battery. I'm using the small charger that came with the plane. The instructions say to charge until the charger light indicates when the charge is complete. Also not to ocvercharge. The charge light indicated a charge after only a few minutes. I had power for all the controls, but had the radio turned on only a minute or so. 2 days later, I don't have enough charge to run the DF, only to work the mixer controls. I disconnect the lipo when I'm not using it.

Am I not charging the batt long enough? I'd leave the charger on a longer time if I could, but am afraid of the overcharge warning.

Any suggestions out there?

Thanks in advance! Beeza

Status: offline 		The good news is that I got the system to work. I'm not use to the musical notes it plays when I first connect the battery. I guess that's when it's binding.

The batt says 11.1 v 1800 ma

You can scroll down for the plane and batt specs. I put a voltmeter directly on the batt and it reads 12.3 volts. The batt never got warm when I charged it last week. Is it supposed to be like this? Everything's running well now.

It shouldn't get warm when charging with stock charger and 12.6 is full. 12.3 might be all you get, that's almost full.
