Re: Using 7.2v charger as BackupBattery
Quote:
The IFI website lists the camera power as "7.2 VDC nominal @ 235mA. 5.2V - 8.6V range max, up to 20 V if internal servo jumper removed." A blanket statement that the camera can run on 12 volts is not entirely true. If you are depending on your camera to help in competition, know that it will fail if the power falls below the range stated. Robot main power for many teams will regularly drop below 5 volts during high current demands and the 7.2 volt backup supply is not tied to the main power. Want to keep the camera operating, use the recommended connections to the backup battery. |

Re: Using 7.2v charger as BackupBattery
thank you all for your advice
[never actually connected the charger as I thought] We disconnected everything from the controlller [all victors and spikes], and got 20 mins if playing time with the camera [and the backupBatt LED never came on].. I guess there were some problems with our initial setup - we'll be more careful next time we wire it thanks again and good luck |

Re: Using 7.2v charger as BackupBattery
Do you have more servos or anything that will eat up your backup battery?

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. |

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) |

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.
