12v Lead Acid Battery charger

Hi I am currently making solar mppt system using the arduino. I have connected my output of my buck converter directly to a 12v battery but now i would like to build a 12v battery charger i have a current and voltage sensor at the output of the buck converter and am wondering if i can monitor and alter the charging of the battery in the code or what type of IC i would need to charge the battery Thanks for reading and responding

hi, Some of us (like me) don't know what "solar mppt" means, or is..

If you want competent help, give links to examples and decode the Acronyns... ---------------------( COPY )-------------------------- Whatever it is, here's a chip for it... :)


I agree, I don't know what you are talking about when you refer to solar mppt. mppt = Maximum Power Point Tracking I did some research (wikipedia WOOT) and so I think you mean yo uare using the mppt method to get the most efficiency out of some solar cells? Is that right?

Dig around on Newark/Mouser/Digikey and you’ll find ICs that will manage this for you.
