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.

have a look at BVM1 – 12 Volt Battery Voltage Monitor then let me know better, how i could help you.
Thanks for the effort and your effort.
I think the www.solorb.com is good. and the instrument looks good and simple to implement. Now I am studying the circuit of solorb

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.
