Small LED Battery Level Indicator Voltage State Of Charge
 

Would anyone know a source for those small LED Red-Yellow-Green (3-LEDs
side-by-side) indicators with a small circuit to indicate the charge
condition in various batteries?

I'd like to find a configurable circuit that can be changed for 3, 5, or
more NIMH cells, and also 12V SLA batteries.

U.S.A. source would be preferred.
