Samples came in. I’m analyzing one now. So far just a few areas that need some beefed up soldering. Other than that it looks good and I’m testing it on the bench. The phase filters and ASS feature really does seem to improve sensorless performance. I will be testing these in my mountain board and ebike. I’ll know pretty quick if it’s good to go. Then I’ll finally order stock!

It sounds great!!
Will it be still 84V-20S, or will it be increased? Any change on the dimensions? Stoked on seeing the case/heatsink you mentioned before and see the new specs and its improvements!
Thanks!

What is tronicsystems? Tronic 250? Another company selling it? Looks much bigger… (hope it does not go bigger, as little focer, was not actually very small, and going bigger will make things much more complicated to fit in)

Does look like it. IMU so no riotn

The Little FOCer is still 20S and the same dimensions. The difference now is that it can handle more current along with some newer features like the phase filters for ASS.

Some may choose to go a bit above 20S like @Fosterqc but it gets risky.

The insta explains it is the esc developed for the RION scooter company. If you look back on the RION ig account there are pics of the many iterations.

so rion and shaman collab?

Tronic is a joint effort between Rion and myself. There are currently plans to keep the Little FOCer and Tronic series as separate entities but Tronic is still a developing project.
