Hi again,

Im assuming that the battery is a Lipo. If you only half charged it then took it out and tried to fly it for a while there is a strong possibility that you over discharged the thing in your eagerness to get going. If the battery is suspect, it will probably be "squashy" or puffy... A good lipo normally wont be like that.

There are 2 things Lipos really object to...
1 over charging... They often burst into flames if you insist on over charging them. (think incendery grenade here)
2. Over disharging... If you discharge any of the cells of a Lipo too much, it also ruins them. If memory serves, the minimum voltage on each cell is 2.1 Volts.

What you are probably getting is the charger refusing to charge the pack because its too low voltage. Usually when they get into that state they are useless.

If you are replacing the battery, you could do worse than flightpower or thunderpower, dont change the voltage from what you have already but you can increase the capacity (mah ammount) a bit at the expense of weight and size. This would give you more flying time ... chargers... make sure that the one you get has some sort of readout telling you what its doing / done and make sure if it doesnt have one built in that you get a balancer.

Hope this helps... Azzy
