My 84-volt Nikola Triumphs, Tribulations, and Failures

Recommended Posts

Thinking about this the last day or two, I'm (wishfully) thinking this really was just a manufacturing error. After all, even my shitty ACM mosfets didn't fry when my cables melted. So it's unlikely the mosfets would have died with proper cooling contact.

Really grateful you plan to repeat the test with the new board, Marty! That will tell.

Still hoping for the Nikola100V/MSX(?) board on future 84V versions though (or at least on the 2100Wh which I'm aiming for;)).

I can say with 99.99999999% certainty that the failure of those 3 mosfets was from the film that wasn’t removed properly during assembly of the board onto the heatsink.

You just couldn't go the final 0.000000001% huh?

:D

Nope. Because one of the mosfets might have failed after the others for other reasons. :P

Cuz they might be  a 0.00000000051% the MOSFET is not beefy enough.

0.00000000023% because of cheap thermal pads.

0.000000000168% poor engineering.

0.000000000005894125% divine intervention etc..

That would be 0.00000000000089% only :thumbup:

They are mostly harmless creatures. Only feeling superior in their $1000 bikes and hundreds dollar worth of skin tight suit.
