I want to make something that charges some supercaps I have (7.5 F 5.5V) in parallel and discharges them in series (to step up the voltage, get some high current limits too). I have a 6V 6A power supply to charge them up (the voltage will be reduced to 5.3V with https://www.amazon.com/General-Purp...519865067&sr=1-3&keywords=10A+rectifier+diode).
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? I do not want to make this too expensive or that complicated, so if the diode and arduino is enough to safely charge them, let me know. If it is not, please suggest a good alternative. Thanks. Also, any suggestions for the project in general are welcome.
