    Is this a safe way to charge a supercap?

    Hi,

    My plan is to use properly rated mosfets to achieve this series/parallel switch (I know it's a lot to do this, but I found a good deal). The mosfets will get here in about a month (arg), so I am in no rush. I am going to measure the voltage at various points with an arduino and some voltage dividers for protection and to know when it is ready to discharge. Because there is a high current limit on the input, and the supercaps will probably explode if the voltage is exceeded, it is important to have good protection. So is a voltage divider to measure the voltage after the diode that then tells the arduino to shut off a mosfet if the voltage is exceeded enough?

    Please help.

    I didn't find the right solution from the Internet.
