Hi all, this will be a relatively short write up just to document my EGO Z6 mower mod to add a 12 volt dc (vdc) accessory outlet to the mower, to power things like a yard sprayer, maybe an LED light bar or work light for an outdoor event, my home made 12v cooler , really anything up to 25 amps @ 12vdc!   The reason you can not do this today without modifying your mower is that the battery system is 56 volt dc, and there are no high current 12v outputs anywhere from the factory.   Hence my hackery....   Just a heads up I have years of electronics experience, trial and error testing, and I get to play with electricity as my day to day career.      Lets go!    First I had to find a suitable DC to DC converter. Surprisingly there are not as many available as I thought there would be, most of them are for kids electric scooters.   But I finally found one on Amazon that covered a wide input voltage and had enough amperage output to be useful, was somewhat water proof, had a large heat sink
