Thanks Phil, will this work if the two batteries are not charging one another, ill use a 100ah auf batt just solar charged, gar is not moved much.For cam operation with a HWK connect "acc" to appropriate car circuit, connect "batt" to auxiliary +, connect ground to both car ground and auxiliary -. Cam will be powered only by auxiliary battery but will switch in and out of parking mode properly.
The BMS for the auxiliary battery should control it's charging with the car doing it's usual for the car battery.
On those fuses, I'd look with magnification to see if there are any scratches where a nut, washer, or terminal connected as a better indicator of new or used instead of fuse terminal color. And even if used, as long as they spec out correctly I wouldn't be worried about them; they would 'blow' to open circuit if overloaded in a past life so used or new would be the effectively the same except for product description.

Has this worked for anyone?For cam operation with a HWK connect "acc" to appropriate car circuit, connect "batt" to auxiliary +, connect ground to both car ground and auxiliary -. Cam will be powered only by auxiliary battery but will switch in and out of parking mode properly.

Thanks again it's working! Wired as you suggested, and ground moved away from fuse box a Bot as central locking was getting confused, had the ground there before.ground is now at cabin filter attachments, both hwk and lifepo4 neg bolted together at that point.Thanks Phil, will this work if the two batteries are not charging one another, ill use a 100ah auf batt just solar charged, gar is not moved much.
Thanks!
I think I’m going to buy a battery pack to get it off the main car battery and hopefully get additional parking mode coverage since I’m not driving my car as much. Additionally, I’m planning on adding a second 2-channel dash cam.
With Cellink NEO I would need to buy two of them to get around 25 hours out of each camera. This would be over $600 compared to something like below which is less than $300:

Due to its size, it would most likely have to go in the trunk and be strapped down really well to prevent it from becoming an eight pound projectile in the event of an accident.
An added benefit is that it would be more versatile than a regular battery pack.
Looks interesting, and should work if your camera is powered by a USB source. If ~12 volts, probably not.I saw that and had the same question, but then I found this

It looks like it might be Lithium-Ion which I've heard doesn't tolerate heat as well as Lithium Iron Phosphate batteries.I saw that and had the same question, but then I found this

Buy an AGM or gel battery or batteries to fit the available space in the car and a DC-DC charger. ... Two 26AH batteries under a seat
victron energy earlier this year finally released information about the importance of sizing of lifepo4 to alternator for direct charging off it no dc to dc converter needed blowing the myth out the water of alternator damage if done correctly.....
this is gospel... 12 minutes in
