Small battery meter for tiny whoops. They don't come perfectly factory calibrated, but the good news is that you can take a reading with an accurate multimeter and then slowly turn the screw you see on the image to calibrate the meter properly.

Great little voltage checkers. Bought a few of them to keep handy in multiple whoop kits. Voltage was not accurate when received but I was able to calibrate them to perfection with the small screw on the back. Newer versions of these take a couple of seconds to display voltage after you connect a battery. The previous ones I got will display voltage instantly when plugged in. Both types work fine but I prefer the instant display version.

Excellent battery tester, the best I think. Better than the other one. Buy this one, and not the other one because it has a better voltage range!!

Nice and compact 1s battery voltage checker. Gives an approximate reading which is good enough for a quick check of a battery’s status while out in the field. That’s what these are made for. Anyone expecting an accurate reading should use a multimeter for reference.

Decent value and a good estimate of voltage, even though it is not very accurate

Great for checking the status of your 1s batteries. Comes with 2 most common 1s connectors, one on either side. Good quality product it should last you a long time in the field.
