Not sure which Lacroix deck you’re into but I own a @tomiboi Honey Badger which is similar to the Protipo iirc and I love it. Solid platorm and available w a ds enclosure. I’d take a good look at his offerings before making concessions trying to obtain Lacroix. My $0.02
Used them, from multiple vendors at various price points. 100% of the time they did nothing useful once i start moving. Too many vibrations even on 9 inch wheels. Also don’t want batteries to charge. One (remote) becomes 5 in no time
Writing an email can certainly get you just parts from them. I wrote them about just a deck a few months ago and they responded. The price was more than i wanted but they seemed willing to play ball email never hurts.
About the bms, because i want to be able to keep an eye on it from just one app, and the vescs to quit drawing power if something gets bad. I’m well versed in the vesc tool, can’t say i found something truly fucked up with no workaround yet. Chinesium apps on the other hand…
Spitend would require their remote i think. Haven’t checked in quite a while what they’re up to.
