Fried chicklet

We are using them two. We have found out that if the battery goes below 6.5 volts then the joysticks start going down. How ever we have not hooked them up with a battery. I have created a circuit that used a comaritor to turn on the LED when the battery reaches 6.5 volt. We are going to use the 7.2 volt RC battery packs that are used for back up batteries providing 1800-2000 Mah.

We completely understand this. We are using a 7.2 volt battery which is at 7.2 volts. However, upon connection to the chicklet, the light on the chicklet turns red and the battery drains quickly, indicating a short. This happens with the joystick unplugged as well as with the joystick plugged in. It is almost certainly a fault with the chicklet, maybe one caused by us, but the chicklet seems in fine condition with no shorts or problems with the board.

A 7.2 volt battery is not 7.2 volts when it is fully charged. It is closer to 9V. Nominally, it should be at about 8-8.5v when fully charged. If your battery is a 6 cell NICAD and it is measuring 7.2 volts, it needs to be charged. The Chicklet is an electronic device just like the camera and the R/C if they do not get the proper voltage they cannot function properly.

Yes. The Chicklet requires a power source of at LEAST 7.2 volts. This is diplayed on the IFI websight under specs.

This is not necessary if you ensure that the battery is fully charged before competition. We did our testing with a 700mah battery and got over 4 hours out of it.
