The high pitched noise almost always indicates a bricked camera, unfortunately, but here are some more things to try:
1. Power on the dash cam via the vehicle's 12V socket and see if anything changes (AKA bypass battery pack)
2. Do a firmware reflash by following the instructions here...
Most of our customers do set the g-sensor in continuous recording to very low numbers (1-2). BlackVue's system, along with most dash cam companies, is definitely sensitive and the reasoning is that the dash cam should rather record something than potentially miss out on something important.
As it currently stands, capacity will be more or less the same. Any higher and we come across some prohibitions in shipping regulations. But nothing is yet finalized so we're working to see what can be done. An upgrade would be nice, that's for sure.
Thanks for all the interest and support!
Yes, our BI-750 is discontinued but waranty is not affected for those who run into issues with their batteries. We also reserve a healthy amount for such claims.
Indeed, we're working on a new battery project but with a loose ETA of 2-4 months from now.
We're discontinued the BI-750 due to sourcing issues with parts, unfortunately. We're still carrying the Cellink Neo and the BlackVue B-124X, and will be coming out with a new battery pack in 2-3 months from now.
