GoLive with both AA batteries and external battery
When a GoLive camera has both AA batteries in it and an external 12-volt battery, which source does the camera use to charge the internal lithium batteries?

It's going to use both. It will start with the external 12v as long as it's fully charged and then when that voltage drops it will switch over to the aa's (alkaline). Now if you use lithium instead of alkaline it will switch over sooner and may use up the lithium aa's before using the external 12v. The camera will also switch back and forth, it's not like it's going to use one source and switch over and then that's it.

It uses the higher voltage source. With a 12V battery, you don’t want to let it get below 12V if you can help it. Lithium batteries top out in the mid 10V so in order for AA to be used, your 12V has to get much lower than it should. You’re probably better off running the camera on 12V alone and swapping it out with a freshly charged one when that gets to 12V.

Thanks John and Diane. I am using 6 Eneloop NiMH rechargeable AAs in the camera (which show slightly over 8 volts fully charged). The external 12 volt battery is a LiFePO4 which outputs 12+ v. over most of its discharge cycle and rather abruptly goes to 0 volt output when it reaches it's low-voltage shutdown of about 10.5 volts. I include the AAs in the camera as a backup in case the external battery gets disconnected or discharges to the point of low-voltage shutdown. As long as the camera draws from the higher voltage source this will work. I use a similar setup in my GoCams (6 v. external LiFePO4 and 4 Eneloop NiMH AAs in the camera) and it works OK there -- I just wanted to be sure that the GoLive did the same "uses the higher voltage source".
