LED Voltage Tester with 510 connectors - Clear Tube Version - Rev. 2
This Voltage Tester will show voltage out of the battery and voltage under load, with an atomizer attached. It reads 2.8 to 25.2 volts and up to 6 cells, and updates at about 2 second intervals.
These indicators may not work properly with some eGo's or other PV's that use linear or pulsing regulators and will just flash.
