    Hi everyone

    I just need some advice on a setup I want to use.

    I have two 5v 170mA solar panels in parallel.
    with the following charge board...
    I need the regulated 5 volts from it too.

    Then, as im not sure if that board is safe enough, I have this...

    and lastly, that is charging a 18650 bat.

    So is this lot a good enough setup and/or do I even need the protection board?

    and if this was a very poor choice of components, what would you guys recommend?

    Thanks in advance.

    You need 4.1V for charging a Lipo cell. No more or disaster looms.
