    Hello, I noticed you have a line in the manual for the DP30V3A that says I should use a diode if I am going to use the DP30V3A to charge batteries to protect the electronics.

    Note in instructions:
    4.6 In case that the current flow backward the module. So when the buttery is charged directly, please add a diode on output positive.
    ——————————————————————————–

    I do want to use the DP30V3A to charge Li-Ion batteries from 4.2v up to 12.6 volts DC at reasonable current of 1-2amps max. I have a sufficient power supply feeding the DP30V3A of 19.6v/12A.

    Can you recommend a Diode I would use for the above battery charging requirements?

    I am also surprised you don’t have this item on your webpage. It is a very nice Voltage Regulator, you should have it on your website with instructions posted.

    Hi Scott,
    if you need a separate output diode to stop the battery from feeding back, please install a Schottky diode more than 30V 3A, such as a 45V 10 Amp diode.
    Hope this will help you.
    Best regards

    Thanks for you help. I have located some of these Diodes but before I purchase, I just wanted to confirm that I really need 45v and 10 amps! I would be charging at 12.6v and no more than 2 amps.

    The biggest battery I would charge is 12.6V Li-Ion. I only ask because the diodes I found for 45v/10A are rather large. Can you suggest a smaller one that would work in my situation?

    This is what I was looking at:

    Ended up buying these for pretty cheap.

    Should work fine, even if they are rated to 1000V!
