How to control charging?
« on: November 03, 2004, 05:46:50 AM »
Should i buy a charge controller?

What is a simple circut i can put into a battery pack to show green or  red for low and high?


   Im thinking that i might rather buy a controller, but it needs to be able to charge all kind of cells from "AA" to 12V DC. I just want it to show a red light as the cell is topped up.


 I searched last night, but didnt find anything specifically how i want it. So mayeb its just something you guys buy for cheap?

Use an LM3914 Bar/Dot Graph Chip

I think most of these would say "Full" before the battery is full. Triggered by the surface charge.
