  3. Its early on Andrew, so the supplier was Valence for the replacement batteries, I know because I have them. The warranties from Valence was five years so though Wrightbus did the work no doubt Valence paid. I installed these batteries a couple of years ago so dates seem right as well for a pack replacement to something else?
  4. Interesting Andrew, because the full module was removed, you would have thought that if Valence were doing the job they would have replaced the batteries only?
  5. Full air conditioned cooling and heating from looking at the system. Coolant pipes in and air con pipes into the unit.
  6. The big stainless steel boxes the batteries were in were water tight and had a BMS and full thermal management. I along with James and Paul took enough apart. One had nearly all new batteries which are now mine others had mostly or all original batteries. Now the question is, is it the replacement batteries that are having the problems? And are they the same as the original setup by Valence? Who knows not me They are Nissan recently said that most leads are still on the road and still on their original batteries in the UK

  8. Mine are safe then, currently having a sleep until spring next year unless we have a warm and dry spell this new year

  10. Then they were the ones I bought, along with James and the others, the packs were 5 years old and had many replacement batteries of which I purchased 30 of the newest. As to why they were failing who knows? In my boat they are lightly stressed in comparison to the bus they were in. Of course it could be down to Valence saying charge to 100% rather than the 80% us second user's seem to do?

  14. As I said Andrew Valence always refers to their batteries by chemistry not the generic name. James had a few sources for the 12 volts valence batteries, but the 36 volts ones were from Wright bus direct, they had done there 5 year service life and were changed for new ones, whole packs at a time I bought 30, others bought them via James, he said it was to much money to it on his own. Mine were all nearly new, I stripped packs down and chose newest which James and I had agreed on.
  15. It is strange Andrew, because my lifepo4s came from Wright buses, I didn't think Valence made anything but Lifepo4s so the article seems to be at odds with itself?

  18. We tend to use Lifepo4s on boats that dont do the above. The batteries you suggest are big heavy expensive and very slow charging, not long lived in a traction situation. I have lifepo4s on my boat which have worked well for 3 years, they are second life and were not expensive

  21. I always find the faster you go the worse the weed tangles are! I think the skin tank for Ian's boat is big enough, I can run my motor for hours and it only gets hand hot, the bilge blower keeps it cool. Running at high efficiency produces little heat just motion
