Car Battery Light Flashing While Driving

While, I wouldn't put a valuable DSLR/Lens on the mini-ball head both my Gopro and iPhone 11 stayed on while driving up to 60 mph on the highway without it sliding or falling off. The magnet is S-T-R-O-N-G. I did not have any problems with the dual-action mini ball sliding around when I was driving with the kit on my car. I highly recommend this kit if you're looking to take photos with it mounted to your car.

I thoroughly enjoy my GoPro, hiking, fishing or just driving in my car.

For major television broadcast work: I use this to hang a pocket light on windshields for driving car interiors. Can alternatively use to help stabilize the camera from wobbling while hanging from the triple suction mount. Love it. Easy to use. Works great.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

My APC UPS sounded off every few hours with beeps and a flashing red light to let me know it was time to replace the battery. I ordered online and the battery arrived sooner than expected. I installed it and it's been working fine since. The part I especially like, I didn't have to shut everything off to install.

I bought this a month ago when the battery died (I unfortunately did not notice the low battery flashing light indicator). The replacement battery arrived very promptly, was easy to install, and my backup is operational again — and just in time because a tornado hit here a few days later and I lost power for 8 hours.

but it is unsettling to have the upstream light flashing

Held my lumix s5 to the front windshield of a car while driving around.

I use these for removing smudges on my lenses. I also keep an extra one in the car for cleaning my glasses while out driving.
