anybody install a lithium battery to support dashcam 'parked mode' recording

[red_gv70]

I have been looking for a dashcam that supports parked mode recording (viewed motion or car bumped). Most that I've found have a device that inserts between the battery and the camera as well as a connection to the ACC ON switched power. When parked the device monitors the voltage of the battery and disconnects when it reaches a preset low voltage point. I see some companies offer an external battery for this purpose but at outrageous pricing.

I have several lithium batteries that I could use. I can build a simple charging device to recharge it when the car is running. The question really is, where is a good place to install the battery? The one I have in mind is for an electric bicycle. Its about 6-7" long X 2" X 2". The control circuit box will probably end up being a 4" cube.

Any ideas?

• FITCAMX Fuse Box Cable Hardwire kit, 4in1 ATO (Regular), Mini, Micro2, Low-profile mini​

  
  After connecting the fuse box, there will be a parking mode function. The parking mode means that the dash camera will start to records while a collision happens. Not continuous video recording.…$56.00

Thanks 20GV7022

I don't want the camera powered directly from the battery when in parking mode. I want to install a separate battery, charged when the car is running, to power the camera when the ignition is off. The brand of camera only matters when I compare the current draw in it's 'sleep mode' and whether it supports 'collision' in the park mode AND 'motion'.
The biggest issue right now is where to put the battery. SoCalG90's suggestion behind the glove box seems promising. I'm going to look under the dash tomorrow.
