eRIC bro, not to kacau your thread but your so-called VS is just a capacitor bank. It's not the same thing as a voltage stabilizer.

I have a DIY-ed VS that has a circuit that cuts or engages at certain frequencies to ensure it always gets power at the right frequency etc etc.

But mine is not for sale.

Just a word of caution for cap bank users, such high cap values will drain your battery eventually if not used for a long period of time. So if the car is going to be stationary for a long period of time (like a week) disconnect the VS and the battery to protect its life span.

A cap bank is like those caps you buy from ICE shops except those are usually at least 1F which is way too big for VS purposes.
