Battery Voltage Indicator

These 3 digit Red LED displays will accurate show the voltage of an attached DC power source with an accuracy of .005 volts!
 
Pin 1 is Ground and pin 2 is + Voltage in..
 
Approximate measurements without the pins are: 23mm wide x 18 tall mm x 10mm thick.
 
Reads 2.8 to 25.2 volts and up to 6 cells. Updates at about 2 second intervals.

These indicators may not work with some mods that use a switching regulator. The LEDs will just flash if you run into this problem.
 
Due to the DIY nature of these indicators, warranty is for DOA items only.

Not what I was expecting
This is a very functional volt meter but I was hoping to use it to switch between my battery voltage to supply voltage with a spdt switch but it only reads 3.0 to 4.9 volt "per cell" and is intended for use with lipo packs in the RC hobby world

Good Voltage Display
Nice little battery display that I used on a dud 510 cartomizer body and wired up the battery connections to. I added some shrink wrap tubing to make my own voltage display that I can screw onto various mods to show what the voltage is currently set at. It's my quick got to variable voltage display I can use on my mods. Very nice, consistent, and works great.

Nice Indicator
I ordered the unit shown here $7 but I received the $15 assembled version with 510 connectors. I appreciate the upgrade but it limited the uses for the indicator. I didn't want to disassemble it so I used one of the 510 battery contacts I bought and put leads on it to make a loose wired tester of it. Works great.

Engineer
This unit is great for making a little mod to check voltage on the fly. Applying voltage for the full 2 seconds needed to get a good reading under load can cause some liquid burning at high voltages. The accuracy is off by about 0.2 volts on the one I got compared to my Voltmeter but I am not gonna complain at this price. The ground pin is as indicated above. The other pins are for 6 different positive connections that share the same ground. Great price!

LiPo battery field tester for r/c
These are originally for r/c hobbyists to test multi-cell LiPo batteries out at the field. This is one of the best prices I have seen on one of these units and it is a nice one to boot. They work great as indicated for building into mods as well.

Quite Handy
Purchased this and a 510 battery extension (male connector on one end, female on other) and wired it up with some heavy gauge wire (for stiffness) and made myself a battery voltage indicator for my 510 mods. No need to use a multimeter anymore!

Works well. Seems to have a 2 second update cycle.Have not measured current draw yet but it causes charger LED to flicker. Nice addition.
