In stock in Australia, fast shipping So what can you use this for? This is purely an LED indicator showing the current state of the battery. I have wired mine up to my motorcycle battery so I can see the state of the battery before i start the bike. It's stepped at 20%, 50%, 80% and 100% Mine showed full charge at 12.92 Volts and above. The accuracy seemed reasonable for a low cost device. It's really handy, you can mount it in your own case or enclosure. Or just hang it by a couple of wires. It's pretty robust. I accidently shorted mine and it seemed to survive just fine. 1, on-board precision voltage detection chip and power regulator chip   2, onboard four battery indicator LED lights, three colors display, red, yellow, yellow, green representing 20%, 50%, 80% and 100% of the electricity   3, mounting holes on the pcb, you'll need to provide your own hardware and wire your voltage source in   4, PCB size: 22.2 (mm) x17.2 (mm)
