A little update from my point of view this evening- I left track at about 9:30... couldn't hang any longer, just exhausted. Staying in the Motel 6 in Victorville- or one of the two motel sixes, which are across the street from each other. Don't understand how that works.
PaulD's bike ate the Lyen controller I bought from Lyen yesterday and installed last night- I modified it to eliminate the cutting-out issue as seen here: viewtopic.php?f=2&t=16910
... I installed additional shunt resistors for a total of four, then used the software to limit the current to what I thought was a safe value- turned out it was running more current than I thought and quit working. I need to troubleshoot it more fully tomorrow. There are some nice melted solder chunks rattling around inside, know that for sure. And one phase of blown fets, at least. Zombiess volunteered to apply his large body of knowledge about the Infineon controllers to help me scrape together something- if we're lucky we'll have a working bike again tomorrow. It was super fast while it was running today, though
If we get it going again it probably won't be quite as fast again
I also rode around a little on my HS hubmotor "bmx" bike, it's pretty good except for the sorts of not quite right things that you always get when rushing to a deadline and not preparing as well as is really needed. I'm not really much of a racer so I may ride it around with the slow gas guys and just have some fun. I think that anyone trying to push it to limits would get very frustrated by all the "not-quite-rights" about it...
Running chargers off the Prius HV battery works perfect and is super slick. Actually tried it for the first time this afternoon at the track. Mean well HLG and RSP are kickass chargers. Kokam cells seem OK and pack builds seem to have mostly worked out, some small questions to confirm when I have some more time but mostly OK. Kokam cells are definitely not the performance level of good hobby lipo cells. They warm up under load/charge and sag more. But they balance nice and are very consistent.
SoSauty and 999zip showed up today, those were the only other ebikers I saw before I headed out. I have heard directly and indirectly that LFP and crew, Farfle and Stevil Knevil and friends are all rolling in later tonight.
Should be fun tomorrow! Looking forward to it!
