Battery Fuel Gauge [RE-wrenches]

[Todd Cory, Mt. Shasta Energy Services]

The only thing I buy from brand "X", and that is the "e-meter" (link 
10). The reason why I choose this over other amp hour meters is because 
of the bar graph gauge. There is no need for the customer to understand 
amps, watts or volts (unless they want to see that information and turn 
it on). They simply look at the gauge and 4 LEDS that are green when the 
batteries are full, and turn to yellow and finally red as the SOC is 
decreased.

I recently ran into my first customer that could not use this as they 
are colorblind, so in this case switching the red LED display on to 
percentage of charge solved that issue. I think this meter offers the 
best of both worlds... techie data and a simple "gas gauge" readout.

I wonder if we will ever see Li-On storage batteries for battery based 
systems?
