Top And Bottom Light Flashing On Shark Battery

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

I got this because I was curious if this could make a good battery mounting plate for my rig. I noticed the top and bottom 1/4 20 mounting points might serve me well coupled with Smallrig's 2 pack Rail Block kit. And it did. It's a great setup for my rig as I run top and bottom rails for accessories.

I especially appreciate the non-skid surfaces on top and bottom

5 stars! Stable and very easy to adjust level with slider on.

I bought the Tascam DR-70D because it is possible to put it in the bottom of the DSLR, and on top I can attach more things like a light and a mic. It is very easy to use and has a very decent audio quality, great for independent filmakers. The reviews on internet point this device as the best of its class on the market right now. The only thing I find kind of annoying is the small door where the batteries and SD card go.

The light is perfect for travel. It measures 14 inches from the top all the way to the bottom of the yoke. Very bright and usable as a key light. I use an Angler soft box with 8"x8" opening. The light must be mounted sideways in order for this to work. Highly recommend for anyone who needs a small light with great punch.
