I’m running 100a battery and 100A per motor without any issues for quite a while now.

How about startup Amps and brakes?

#160

100A breaks is sharp but never had any problems with it. What you mean startup amps?

#161

Asked this question once “Does unsensored FOC get cogging?” and @mmaner answered “ Not really, if it does up the startup boost value”.

So apologies, not startup amps, but startup boost.

Tight, matter of fact when I add the rubber standoffs under the corners of the Unity, I reckon it won’t move at all. Backpack electronics enclosure build started!

Absolutely unfathomable.

Like it was tailor made for the Unity, just enough gap around it for airflow with the plastic standoffs just inside the screws.

What happens if you fall off and accidentally squeeze the throttle and the board flies away?

#171

It unplugs and stops as designed, this has already been tested three times when I fell on my ass. There is stress relief on my connectors at key points.

Lmao best thing i read all day. What plastic is being used though? i would be scared that the unity heat-sink might melt the enclosure in the long run

What plastic are electronics enclosures usually made of, PET?

Doesn’t really matter, because it’ll have active cooling anyway.

You have space for watercooling in your backpack. I have some old GPU PC blocks I’m planning to try with FocBoxs - backpack would be so perfect :slight_smile:

Was thinking air, not sure I’d want the added risk of liquid cooling. It’s fine for a stationary PC case, but for a backpack that should be able to take impacts?

I don’t think it’s a good idea, plus added weight and bulk, I really think air cooling will be enough. More so since Unity’s do just fine inside sealed enclosures.

the only part I worry about is the reservoir I thought about using something like this to survive a fall

I was into PC water-cooling ~15 years ago so have lots of old crap lying around - saw someone testing the temp differences with VESC using WC and it rekindled my madness :wink:
