So, what sent you down the electrical field?
I worked on the cutting edge so to speak of aftermarket computer fuel and electrical computer stuff as well as adapting the computer and various outputs for engine upgrades like a V6 commodore engine in a Mitsubishi 2.8ltr diesel Pajero and replacing the Hilux 4cyl petrol motor with a V6 Commodore engine ... as well as upgrades to the computer systems to handle higher boost on a whole range of turbo cars. I also worked as a plant mechanic on rail equipment that was all electric over hydraulic and sorted the night time running issues where they hydraulics no longer respond after about 5 hrs running. Then worked on big site crane building at the same time as they were just starting to install computer bases motors and computer controlled hydraulics. later I work in the maintenance dept of a pipe coatings plant that ran on computer based C++ machine language so I got to be the interface between the fitters and the electrical dept.
What got me into the solar and lithium batteries was trying to build a solar/battery system for the big bus to run the air con over night as well as all 240vac appliances. I started out with 28 x 100Ah AGM batteries that had been removed when the No6 blast furnace UPS was upgraded. This where I discovered that it wasn't simply a matter of linking 12v batteries in parallel to supply the 100 amps I required. In theory, I really only needed 20 x 12v batteries to provide the 100 amps while only drawing 5 amps per battery so I could retain the 10 hr run time before the batteries dropped to 50% SOC and I could recharge at over 100 amps ...... that came crashing down when 28 x 100Ah lasted about 3 1/2 hrs. That lead searching for a way to get an even current draw from every battery in parallel ... can be done but the cost and equipment size was impractical.
Then I went looking for an alternative to lead acid batteries and that is where the whole thing really kicked off. Everything I read on line made no sense because there was no common thread anywhere that allowed the wheat to be sorted from the chaff, so the only approach I could see that would work was to get some and do the testing myself, $10,000 worth actually ....
I tried to share what I learnt each time (at my own expense) with the CMCA forum and the Caravanner forum, those who knew everything there was to know hounded me until I was finally banned from the Caravanner forum and given a weeks suspension from the CMCA forum, which I never posted on again.
Funnily enough, the same trolls turned up on the grey Nomad forum and eventually I got banned from there as well .....
