content: Hmm, dubiously rebuilding a lithium-polymer battery (albeit LFP) in a $2mn supercar... no, can't possibly see fire being an economic hazard there.

content: Yeah salt water corroded repairs... no thank you.As for the battery, typical proprietary BS. You could just buy a new LiFePO battery for $250 if it didn't have that custom communication connection on it. Put a hall sensor or shunt on the wire then sense it somewhere in the cars circuitry.Quote from: tom66 on June 16, 2023, 08:59:15 amThe cells won't catch fire at least.

Look up part from the main dealer and its £100, go to parts shop and they look at it and rummage in a box and find one for a tractor that is only £2.50. Many hyper cars use standard parts for easy stuff with just some special bracket to make it annoying.Seen a few of these buy and crashed car and fix it up type things. The money to buy the wreck is still scary and it's quite a gamble. Some of the vids it's clear they just get somone else to fix it they just video it. Fine if you have money to waste.

content: I'd suggest checking Tavarishs' secondary channel as well.He had a talk with "V engineering" in UK, who happened to have redesigned the main P1 drive battery (in cooperation with the people who designed the original battery). The original battery seems to fail a lot.Rich used parts from the original (now bankrupt) manufacturer, just a little bit less capacity. And even though he hacks things together, he does amazing work.Btw. other manufacturers offer Li-based batteries as well, and those are thousands as a replacement part as well. Multiply by factor 3 for "supercar"

A temperature sensor for a Triumph Daytona £68.99, same sensor for a DAF lorry £2.50. Don't get me started on Marina door handles as once you start to see them you can never not see them.
