I noticed that my car's voltage drops by 2.2-2.5V when charging the battery pack, triggering the low voltage warning.
I do not think the voltage drop was that much when it was first installed, but I do not recall.
Edit: Just realized I got my wording completely mixed up. Car voltage is fine, but when the CellLink Neo is set to draw 9A and charge via a hardwire in the fuse box, the charging voltage seen on the CellLink Neo is 2-2.5V lower than what the car battery is. This causes the low voltage error on the CellLink Neo app and stops it from charging.
When the battery is tested with other vehicles, there is only a 0.5-1V lower difference in the CellLink Neo voltage and car voltage, and it charges properly.
Also tried hooking up a brand new CellLink Neo battery, but having the same exact issues.
Dashcam/battery wiring has been tested and confirmed to be working properly, including ground points. New car battery installed too.
Any ideas as to why the voltage drop is significantly higher in my scenario?
Another piece of information: When using a wall socket adapter to charge at 12V/5A, the CellLink Neo displayed voltage is 11.5V and charges properly. The new CellLink Neo also demonstrated the same voltage when charging, so it seems the CellLink battery is not the issue.
