But I continue to have an issue that I'm pretty sure is not related to the Cycle Analyst, where the power delivered by the motor suddenly drops in half while climbing a 2 mile steep (1500 ft rise) hill. If I stop for a few minutes and restart climbing (I don't reset anything, it stays on the whole time), it works at full power for a little while (several minutes).
It seems to only happen while doing such a long continuous climb. It doesn't show up when I do a bunch of shorter (but equally steep) climbs followed by downhill or level travel.
I did check all the Phaserunner v2.0 settings and they seem correct based on the V2.0 Manual and some earlier feedback from Grin Tech. I will post those at the end of this.
I did check the CA diagnostic view while the sag was happening and:
- None of the Limit Flags are set (other than the expected intermittent W flag)
- The Throttle out is pinned to 4.00V while I'm pedaling or throttle is on full during the power sag)
- It does this with PAS or Full Throttle (i.e. its not a PAS issue)
- Motor temperature has never been more that 70 to 80 degrees Celsius during the climb.
The setup is:
- Recent Crystalyte H3540 with statorade, 35mm laminations and aluminum stator core (should be able to do 1500W continuous)
- Cycle Analyst v3
- Phaserunner v2
- Two Grin Tech B5213LiM-DT 52v 13Ah 25A Continuous Output Batteries in Parallel (so 50A Continuous Output total)
- Thun Bottom Bracket Torque Sensor for PAS
- Thumb Throttle
- ICE Adventure Recumbent Trike
- Total Weight (Human, Trike, Motor, Battery, Misc Stuff): ~325 lbs
Would love to hear some suggestions on how to debug this or how people may have fixed something like this before. Below is the Phaserunner setup.
