Battery Level Indicator

Do you have a battery level indicator for a 24V Ni-Mh recharegeable battery source ? Prefer the display as a LED or LCD traveling bar graph.

This circuit uses a LM339, a quad comparator. LM339 can work on single or dual supplies, it has a open collector output that can drive 15mA, low power consumption. The circuit is an untested design but it should work. I did it as many searches were made in my webpages with these keywords.
