@amberwolf thank you so much for responding to these various questions! Actually, my multimeter(s) are correct and the CA3/phaserunner were displaying the wrong voltage. I did get the answer back from Grin. I incorrectly assumed the voltage calibration setting was in the controller, not the...

I used to be in the semiconductor industry. Not every chip is perfect and exactly to spec. (However, this is very rare.) This can cause various anomalies like this...

To close the loop on this. It looks like it is a rare issue with a very limited run of the CA3 hardware. Grateful for a warranty replacement. Sending the old unit back to Grin for analysis. I decided to upgrade my controller to a Phaserunner since I'm rewiring anyway. So, now I have this...

Recently decided to replace my old Lyen 12fet controller and upgrade to the Phaserunner V6. The installation and testing is going well with the one exception of inaccurate voltage sensing on the controller. For example, my 16s pack shows 67.4v on the Phaserunner utility (& CA3), but the actual...

Thank you for the confirmation. I'll send this to Grin and see what they think.

I had the opportunity to try the suggestions (resetting to defaults) and verified it is definitely an issue with CA3 firmware v3.15 and beta firmware v3.2. Reversion back v3.14 again and speedometer function works fine. @amberwolf appreciate any recommendations. My hub motor is a generic 9C...

Good suggestion. Yes, I'll try resetting to defaults when upgrading and manually reenter parameters. Thank you!

Just recently updated my CA3 to firmware version 3.15 (latest stable) from v3.14. However, the speedometer function of the CA3 no longer worked (displays only 0.00). I verified the "pulse" settings (23) for a generic 9C hub motor. So, I downgraded back to v3.14 firmware and the speedometer...

It's a 9c from ebikling.

Well... Here's an update of my forever modified DIY ebike. Original picture of broken down, nonfunctional, rescued off Craigslist full suspension bike: Here's the "current" revision of my ebike with a custom 16s 67v 30ah battery that fits perfectly in the bottom of the rear rack case:

Sent PM about Sabvoton V2

Haven't viewed or posted for a long while. Thought I'd share my rack solution. I went with a multi - purpose platform carrier. Like this image below: Rated for 750 pounds. I added a Lund bike carrier attachment to my harbor freight platform. Total cost is around $85.

Just wanted to say thank you very much to zombiess for this thread! I know this is a very old conversation, but it resolved my issue with limited regen voltage options for my 12fet Lyen controller. XPD was not working for me. I'm running a 16s battery and the default options in the software...

Good question and thanks for posting this. I have the same question at a slightly different voltage. Subscribed

I didn't see an answer to the lyen programming cable compatibility question. I have a lyen 12 Fet and his cable does not seem to successfully upload to the controller. (download seems to work) Thank you
