When I did the Workplace Training and Assessment Cert 4 the basic rule was to Keep It Simple .... then I started an Advanced diploma in Electrical and Computing Technology ,,,,,,, it seemed they didn't attend the Workplace Training and Assessment Cert 4 course I later discovered that none of them had that basic teaching degree yet it was a requirement to be a TAFE teacher .....jon_d wrote: ↑Fri Jan 07, 2022 4:59 pmThe bit that messes with my head is electron flow is opposite to conventional current flow .... basically because the founding fathers got it wrong .....

Why bother. They are not there to get a masters degree, but some basic information to get lithium started on the lithium journey. Cast you mind back to a Taggerty meet and the questions we all asked back then.
Then, throw in some honest info about drop in and the advantages and disadvanges of having them; how to look for the differences and suitablity for your particular usage and how they still need some good capacity tracking. And then compare to doing your own install using Winstons or something else.
Plus add in the risk of buying out of China yourself vs buying locally.
If you want a bit of a T1 promotion, towards the end, add a little about how you fix the problems that even a 'drop in' won't fix.
You'd have a great 1 hour presso.
I actually did a demo with 4 x 100Ah lithium batteries, side by side, all powering an inverter and a 2,000w load. I had a Victron BMV on the otput of each battery and put all 4 displays up on a screen .... the feed back i got afterwards from someone listening in on a happy hr chat .... one bloke said he clearly needed to get another two drop ins to go with the two he already had the rest said it was too complicated to understand but clearly 4 x 100Ah 12v batteries was the same as a 400Ah 12v battery ..... You can lead a head to knowledge, but you can't make it think ......
