I have a farfle swingarm, running whatever my aging 20C Turnigy packs put out, which is generally something over 15kW on a good day. No axle nuts and the steel is holding fine so far. I have yet to notice any axle movement when going from WOT to about 3.5kW regen, which is really harsh stuff...

Resting. If the loads are sane don't pay much attention to what voltage the cell is at while loaded, from a cell perspective. Obviously the IR needs to otherwise be accounted for electrically.

Most commonly, a fuse is used to protect wiring. If the controller has a fault that causes the fuse to pop, it most likely has a big problem and is toast anyways. No fuse would simply allow the fault to correct itself, typically by going up in smoke. Lets say you are using the fuse to 'protect...

I managed to dump the bike at something like 20 a few days ago. Apparently one hand on the bars is not terribly sufficient with a bit of unintended throttle. I'm mostly fine and the bikes fine. Just burned a hole in jeans and a shirt, a little road rash and an ankle injury. I'll be fine in a few...

It was never really the plan, it just ended up like that. I've repaired most of the controllers without fuss. A lot of failures were really 'soft' and I often only replaced the FET's that shorted. My current 12 FET LYEN has most of its original MOSFETs. No matching or anything special, just some...

I recently blew up a 24 FET. Expecting it's failure, I just left the 12 on the bike, and thats what I'm running now. The MaxV is set about 1/8 - 1/4 turn above where I no longer see any impact on the freewheel speed. I don't really pay attention to what the bike draws. I've been slowly...

I do a lot of stupid things with the bike, all the time. The throttle sticking on, even for a relatively brief period, is a very bad thing. Sure, I could grab the switched brake lever, but that would turn regen on, which given my very high regen power, can be just as bad as unintended...

If I roll off the throttle it's fine, but I'm not a big fan of the fact that the throttle 'sticks' on for a bit should I need to snap off. However I have the board configured, even with all filtering 'off', it feels like the throttle input gets lost for a brief period, and it sticks on when I...

It's most noticeable to me I slam the throttle on from a stop, get up to 20, and snap it off. I continue to accelerate at full throttle (or nearly) for what feels like about .2 seconds. It's very repeatable and I consider it to be very noticeable. As long as you can easily feel the bike...

The delay is BY FAR the most noticeable on my bike when accelerating at full throttle then slamming off while the bike is still pulling. It's been extremely noticeable 100% of the time I do this. Certainly would be nice to have another opinion on this delay.

I almost dumped the bike twice while doing rolling heaters. The throttle sticking WOT is a bit more of an issue than I initially assumed, even if its only 120ms or so.

You might need to put a big yellow sheet in there that says RTFM. I assumed no documentation would be included, and ended up ripping the instructions in half opening the mailer. That certainly didn't help my odds of reading it. Little arrows with +'s on the silkscreen might be a reasonable idea...

Turns out the instructions are somewhat useful and fairly comprehensive. I have the min and max voltage set about 1/8 turn away from ideal. 26" 5404, a little over 100A @ 24S LiCo. I set the two adjustments to the minimum an it appears to be quite responsive. I should be able to mess around...

Nevermind, my fault.

I have about 10 minutes of seat time with this installed. No adjustments were made aside from initial min/max throttle voltage. It's about 30ºF outside, so its not the best conditions to be going 50. I will be doing a more detailed review when I get everything dialed in, but this is just my...
