Regarding the electrics, they are confident in their work but I’m not sure I would agree and travelvolts (who did the subsequent work) definitely doesn’t agree. One point of concern (if I hadn’t had it changed out) is the fuses and rating of wiring. The explanation given is that the wires are triple rated and therefore can take 150A instead of the 50A. I have checked up on triple rating and as far as I can see it only means that it meets the requirements for Uk, us and canada by going with the highest spec of the three. Therefore it was still the case that the wiring was rated to 50A and the fuse was 80A therefore redundant.
I also still disagree with their opinion on the validity of using the split charge relay but again this is highlighted in the build spec and so can be upgraded if you want greater performance.
