Before Dave. (Click to enlarge) After Dave.


<Gulp> ... I've seen grown MX-5's gnaw their own wheels off rather than talk to "Dave". We sure won't be letting "Dave" anywhere near our MX-5.

Well, exactly. It's just that the West Australian Government article linked by Weber above said that angle grinders should never be used for cutting, always use a special purpose cutting tool like a drop saw.
I guess they weren't thinking EV conversions when they were writing that page...

Sorry acmotor. I was referring to EV2go's comment "...it’s not the tool, it’s the tool behind the tool where it all goes wrong..."Re tools..
No no, I thought I was saying that it is the user that makes it safe.
That includes the user chosing the right tool or at least having the skill / judgement to manage the tool.
BTW, is the suspension rubber mounted to the body ? Sorry to show my ignorance of the MX5.

I'm guessing that an actual battery box with a steel floor could be as strong as the original... would you agree? I must have done exercises like this at Uni, but that was a few years ago now.

Yikes! I find it hard to belive there are cells that can do 30C without suffering damage from internal hotspots. I'm not familiar with EVPST cells. Can you point me to some test data or manufacturer's specs?If you just want 100A+ continuous, then smaller capacity, high output could be the go, e.g. EVPST 7AH, 8AH, 10AH which will all do 15C continuous + double that for 10 seconds.
