Cut the 3 foot cables today into 3 equal pieces..

And than found out that I do not have that insulation shrink warp stuff in that size..

[MPaulHolmes]

oh dang it. I used to have some that was slightly too big, but that's probably not helpful right now. It's all about the desire, and never actually making it to the destination. Just think about how boring it will be after you actually are driving it around! haha.

Mounting the DC DC:


Clamping:


Heat shrinking:

Notice a small igbt is holding up the cap

[MPaulHolmes]

With the kit, I could just include one of those IGBTs. Forget the enclosure! Just glue the IGBT in there to hold it up. bam. Instant millionaire. I'll share a little with you for having the idea.

Made some sort of end cap


Bench testing the output on 30V.. seems ok


Nice and tidy


The old and trusty 1000A beta.. about to leave the car


Spot the differences


Dodgy mounting.. for test

[flores]

And for those who are really paying attention.. yes B- and B+ are reversed in the controller.. I couldn't get the end cap on otherwise.

[flores]

Oh yes..
