    Motor Turns Slowly in Reverse After Stopping

    Mystery solved. Obviously this is not a new issue. It's just that I didn't notice it until I got it up on the jack stand the other day. The issue is the controller was set for a throttle voltage range from 0.2V to 4.0V with a brake start voltage of 0.0V and brake max voltage of 0.2V. The...

    Motor Turns Slowly in Reverse After Stopping

    I have an ELF (with a mid-drive motor that goes to a rear freewheel). The motor is a XOFO DD45 and it runs off of a Grin BaseRunner v4 L10. Though I don't think it is relevant, there is also a second motor running on a separate controller, both running off of my CycleAnalyst v3. I recently...

    High Output Battery Pack

    Yeah, I'm familiar with that and these are definitely not genuine. I've read, many times, that knock-offs are pretty unreliable, but I guess I had to learn for myself. In any case, I guess I can't complain that the 45A connectors failed under something probably approaching 80A for over a...

    High Output Battery Pack

    What I forgot to mention was that I ordered a new BMS. All indications are that the cells are fine and the BMS is lying. Even if there is a problem with the cells, I'm pretty confident I can't trust the BMS to tell me the truth. Of course, it is entirely possible it isn't the BMS at all, and...

    High Output Battery Pack

    OK, for anyone who cares ... here is what I did/learned. I did some tweaking. I set the CA to limit power to 80A (and 4000 watts) and made a few other tweaks that I don't think matter, for this issue. I did some test riding/logging and found everything looked pretty reasonable and I wasn't...

    High Output Battery Pack

    Yeah, I'm going to go out and do some logging to find out what is actually happening. Anecdotally, the power is great ... until I hit the cutoff. I think that the voltage is dropping to around 42V, but I haven't confirmed that. (My cutoff is set to 40V.) I don't yet know that the current is...

    High Output Battery Pack

    In fact, I do. I originally pulled it out because I blew a hall sensor (a careless short). At the time, I didn't know it was something that simple, and I needed a FAST repair, so I just replaced the motor. So now, it is just collecting dust. Might need a little work, but you're welcome to...

    High Output Battery Pack

    Sorry this is so long. The TL;DR version is: I have two motors and a high-output battery pack that seems to be overwhelmed by what I'm doing with it, and I'm not sure the best way to fix it. Long Version: I have an Organic Transit Elf that I have modified. I swapped out the stock mid-drive...
