Li-Po battery monitor / volt meter

[stellar]

I found a great schematic for a battery monitor, probably as light or lighter than the commercial stuff. This guy uses a buzzer on his, but I will either add a led or just use a led ( a very bright one ) w/o a buzzer. very cool.

Check out these.

I accept paypal and post worldwide. I now use a new pot/knob to adjust the voltage, not a screwdriver. This is slightly larger and easier to do :D . Also available, an 8-9-10 alarm with the same lights as the 5-6S alarm. Any questions, PM me.
