QIDUHUQIMetal Micro Color OLED Voltmeter D-Tap/P-Tap Splitter for ARRI/RED/Sony/Teradek/Smallhd/DJI/Anton Bauer/Core SWX/IDX/Bebob, Aluminum Alloy,1/4"-20 Screw Threads

Very solid build qualityThis allows me to see at a glance what my rigs power level is at, but most importantly, it shows what the voltage of my V-mount battery isMy batteries are 14.5V, peak charge at 17V and bottom out at 12VThis screen helps me to see when I'm getting too close to over discharging my batteries which would damage themVery happy with this purchase, highly recommend

Great for keeping tabs on client monitor voltage.

Great tool for any AC to have. Helps me out all the time to make sure my monitor battery doesn’t die.

great product but this product is not oled as claimed in the product description!

This a great little accessory (and little is a good thing) that displays your battery's voltage and percentage of remaining power. It can be mounted anywhere on your rig that's convenient using the ¼"-20 hole on the end of the unit.The tiny display is bright, contrasty and easily readable from a distance with only a quick glance which is much more convenient than trying to look at the less-than-convenient displays on most batteries (the ones that have them) which are often too small or lack enough brightness and contrast to see at a glance.A great little device that you never knew you needed until you have it. It's especially useful for older V-mount batteries that don't have a built-in display where you never know when its going to run out of juice.
