Hi all,

Contrary to expectations, I have now managed to complete the installation of the replication PCB and checked it against all the diagnostic checks in the manual, about 2 weeks earlier than expected. The extra time I had assigned for potential problems was not needed and so the manual and associated appendices are now complete together with the Gerber files with some minor adjustments to the PCB.

All the files are uploaded to the Mega link given earlier: https://mega.nz/folder/YUM0nLoT#bYpLIazqMM5K2IrEQjghDQ

and also to this Dropbox link at: https://www.dropbox.com/sh/td55b8675vvqtbg/AADzPSKMOI8q_YM1cFUT2T07a?dl=0

I'm sure questions and comments will arise but I will address any in batches rather than every few days or so.

There's still plenty to do besides the power tests due to start in a few weeks, such as preparing a discussion paper for how to prove that the 'consumption' of the electrolyte is not the source of the measured energy gains.

Believing it isn't is a long way from the evidence that it isn't and this question is pretty much as important as showing an energy gain in the first place, and for which the upcoming power tests hopefully will give the much-needed confirmation.

Onwards

Just a quick note to say that I have corrected a couple of typos and a wrong figure in Table 7 (p37) of the Manual and have replaced the file for downloading as required.

To aid in acquiring components, I have provided a BOM using Farnell as a reference for item order numbers. For those items that can't be got on there, I have provided links to other sources.

I attach this document but it is also now in the 'PCB Files' folder on the main link.

A quick update: Load tests are underway that should indicate if a 'genuine' energy gain is occurring. Despite my CoP test results, there is going to be a difference between single-cycle tests and end-to-end cycles as used with battery swapping where there is little or no time for the chemistry to migrate within the electrolyte. The extent of that difference is as yet unclear. Some initial results will be posted in due course.
