    Hi everyone,
    I'm designing a 48v lead battery charge circuit. However, I found a charger diagram designed for 24V lead axit battery, so can you help me modify the 24V battery charger circuit ( the components' value such as: R, C, Q ...) so that I apply the charger diagram for charging 48V lead axit battery.

    Thanks you so much!

    Here is my 24V charge diagram designed

    That circuit is a 12V battery charger. Have you posted the right one?
    What is the manufacturer's recommended charge current for your battery?

    Converting that 12V charger to 48V would be just like starting from scratch. Most of the components will not stand operating on ~50V.

    Thanks for your help!, I don't know how to design a 48V lead axit battery charger circuit. How I should do now ?, or Can you share me a 48V lead axit battery charger circuit.

    How many Amp Hours per Lead Acid battery?

    12AH, if we are to believe the title of the thread.

    I didn't know there was such a thing as a 48 V Lead Acid battery. But as others have said you will need entirely different components. Do they make datasheets for such batteries? I'd like to see one. That would be my starting point for a new design. Tell us how much you want to spend on developing this charger.

    So next questions for the TS:

    How fast do you want to recharge the battery?

    What is the power source? Voltage? Line frequency?
