Re: Using 7.2v charger as BackupBattery

2 -3 hours? wow... we dont have any other servos connected, so nothing else is eating the battery's power. I will conduct a full test tomorrow and see what we get.
What could be wrong in this case [except for a faulty battery/camera]? It just a simple battery <-> controller connection.. weird.

Short on the back of the camera? Take it off the pan/tilt mount and see what kind of battery life you get. Do you have another backup battery? If not you may want to get another for a couple reasons: You will discharge it during a competiton, and you will need one for the robot while the other charges. It will also assit you here, as you can rule out the battery being bad.

For now, you may want to see if anyone on your team has one, as the connector/battery is common in RC cars. Someone said in this thread, they gave the backup battery connector 12v, and it worked. You may want to try a 9v battery connected to it, but there's the chance of frying the RC (I take no responsibility)

I don't think a 9v battery will work; the RC draws a lot of current from the backup battery terminals!

Re: Using 7.2v charger as BackupBattery

3-4 mins is too short a life for the backup battery, but it is long enough for competition. We plan on bringing 3 backup batteries and switching them between every match just like we do the 12v batteries, especially with how important it will be to not lose camera power mid-match.
