Hey guys, long time since I posted.
I recently sold my car which my dr900x was in, and put it in my Tacoma. I was using dash cam batteries in both vehicles but due to my short commutes 9 min to work and 9 min back typically, not including any shopping, I would only get about 3 hours of run time running the cam with the 4G module with the blackboxmycar bi-750.
My Tacoma has a 92ah dual purpose starter/deep cycle ABM battery (https://www.batteriesplus.com/product-details/auto_light-truck/battery/x2power/sli27fagmdp) so I figured I'd try it without a dash cam battery. Hard wired to the fuse box this time with the blackvue included hardwire kit. Set the voltage cut off to 12v (although after reading another thread here I see an AGM should be okay at 11.8 so I'll switch that) and a 12-hour time limit. I wanted to be able to run my whole 8 to 9 hour work shift.
Obviously the problem is I don't drive very much, I was hoping that my extra driving while shopping or on weekends driving a lot more I would be able to keep it topped off each weekend but that doesn't seem to be the case.
I bought a smart battery charger and charged it up to make sure it wasn't low just because since I had been driving my car daily my truck sat a lot and probably had a lot of drain from the vehicles computer and security.
Even after fully charging it after about the fourth day it was getting low voltage and cut off before my work shift.
I decided to try setting the cutoff to 12.5 because the only options are 11.8, 12 or 12.5. I again charged up the battery last night although when I went to the garage in the morning the charger was shut off even though it's supposed to switch to float mode so I don't know if it had an error. But either way I still only got three or four hours of runtime with the higher 12.5 volt cut off. I don't see what the 12.5 volt cut off is for if most healthy batteries are around 12.4 to 12.9. unless maybe my charger just had an error and never really fully charged it last night I will have to try again.
I really wish when I parked in my garage at night it didn't have to run through the time limit. I had suggested to blackvue a geofencing feature that would shut off your parking mode when you are at home.
Anyways, do you guys think that four days of parking mode before I'm starting to get low voltage because of my short driving commutes seems about right?
I am contemplating what else I can do besides setting it to 11.8 volt cut off. I used to have a thinkware camera in my truck and I would actually hold the power button to shut it off whenever I got home, but with blackvue the only option is unplugging it. But then I would have to remember to plug it back in every morning.
