When the stator temp was reading 60°C I think the controller was reading 53°C My BBSHD is a few years old. I have no clue the exact age...

All right so here's some data. Going in to town today I was able hit the thermal cutback. The limit is pretty much perfect, I dropped...

I'll dig out my thermometer today. The controller side should be the closest internal/external temps because of the heatsink...

OK, so I did another speed run today. The ambient is around 83°F. At about 6.8km this time I experienced thermal throttling. Check temps...

Curious what warm is for you in degrees. Sitting at 64km/h for 7km without overheating / throttling seems crazy to me, when I ran a 45a...

Yes, I'm shunted to 50A. (I think, I always need to do the math). Then pushed to 33A with Danial's firmware for a 55A total. @ 58.8V...

That's some serious juice! ~40mph for ~8 miles? That's a lot of watts! Are you running a shunt or something? That feels beyond the...

Warm here yesterday and I was able to get it up to 70 again. I ran full out doing getting up to 64km/h for about 7km, then full out...

last time riding i got my bbshd to 70°C while riding a hill. the motor was hot but not so hot that you cant touch it. my friends bbs02...

Daniel, what is the high temp cutoff on the controller? I don't think that can be changed from your config tool. I think it's cutting...

Nice, I appreciate good data. I think the discrepancy lies in the fact that the temp sensor is just a "general" measurement. Magnet...

Success! I got mine up to 70° C and it started to cut out. ETA: I suspect the limit is 75°C.

No. I just got back from doing some tests. Running full out on throttle, ~3000W and +60km/h @81°F ambient my controller only got up to...

Just to follow up, I'm not sure about the BBS02B controller. I think it was the BBS01 controllers that had issues with heat, from the...
