Hello,
I am trying to setup an action camera (cheap SJ7000) to take timelapse pictures underwater for a couple of week in the field.
I bought a 12v to 3.7v converter, removed the battery and then soldered the + and - of the battery to the converter leaving the center pin alone and insulated. The camera powers up but because it cannot test the battery, it is shown as empty and the camera powers off.
How do I prevent this from happening? I cannot use the USB port (camera goes in PC or storage mode, no firmware update can fix this). Can I keep the battery plugged in and then have the equivalent of two batteries in parallel?
Thanks for your answers!
