You don't need to worry about pushing too much current to your pack as it's very unlikely your motor would be able to generate anywhere above 20A.
Your generated current would be a function of your motor configuration, speed, bike weight, and incline. The most I have seen is 30A braking while going downhill from 50mph on a 150lbs bike on a QS205 motor (V3 extra copper fill and 50mm magnets). That's at the max regen force setting of 200.

For the most bikes (like those with MXSUS 3K and aluminum frame, i.e. with weight in the 80-90lbs range) the setting of 100 would be just right. But you can set it all up to 200 and then work it down to see which one is best for you. No harm doing that.

What's a good value to set for regen force?

I use 10 of these batteries which have a max charge rate of 5C. So my 20S 10Ah pack would have a max charge rate of 50A.

I've found the sweet spot of 70 for regen, just a nice speed reduce with no lock up in the wet, nice for shaving speed. Puts at 6a or 1c on my pack. More than this would put some solid tension through the torque plates

Real world KW , how high are people pushing this controller? I'm running 6.8kw max, things warm up a bit, but not too hot. 220 phase on 62 @ 110v inc sag. When does phase get the better of this controller ? 220 feels like I'm near limits ?

Larger size, more power. That's how it works.

I have a question around regen volts. Say I have a 100v pack and the regen voltage is 130v. The pack voltage will only ever lift 1-2 volts on regen, does damage occur ? Or are we just thinking about overcharging a pack on full charge down a huge hill. Is the battery packs shear size protection in itself ? The battery pack rips the voltage down to safe levels ?

I think this pretty much sums it up
ZOMGVTEK wrote:That setting is basically just an upper limit, and not terribly useful. As long as its set below the max voltage the MOSFET's can tolerate, its fine. You can run anything below that. The current going in, and resistance of the battery will dictate what the voltage rise is under regen. Those Turnigy cells have very low internal resistance, so it would take a MASSIVE amount of current to raise the battery voltage to dangerous levels. Typically not even possible, plus most controllers have a rather soft regen current limit of something like 10A. The only thing you need to be aware of, since it will 'allow' up to 72V or so, is you can theoretically overcharge the battery. In practice, this would mean you'd need a battery at 100% SOC, and then a HUGE steep hill, and ride regen the whole way down. Unlikely. Even at 4.2V/cell, you could ride regen down smaller hills fine as long as you have enough battery capacity so that the voltage rise isnt terribly significant. Some people like to avoid using regen right off the charger that run 24S LiPo, since that will create higher than pack voltage that could damage the 100V MOSFET's already near or beyond design spec. As long as you have 10-20% overhead, I wouldn't worry.

I only charge my cells to 4.10v/cell, so they have headroom even when 'fully' charged, and I don't worry about using regen RIGHT off the charger. But then again, I also have my HVC properly configured with XPD. It's still unlikely that would help much if for example, the battery connection was loose and I was riding REGEN at high speeds. Loosing the battery connection under load would likely create a voltage spike that can kill the MOSFET's before the controller even knows about it and has time to react.

I think the only way you would have a problem is if you went down a really big hill immediately after coming off the charger.
If your BMS tripped or pack disconnected while in regen mode, then you would want the maximum voltage to be less than what the controller can take.

I would normally set the regen voltage just a tad lower than HVC. Like one 24s, I would set it to 99v while the HVC is 100.8v.
That way I will always have regen functional (due to a voltage sag under acceleration) but will not push beyond the designed 4.2v per cell.
I see no reason setting it way below HVC as that will make regen unusable for the first few miles.

This question is for anyone using the Bluetooth programing on these controllers.
As I am an old school old timer and still use flip phone, I need some recommendations for your favorite Android Blue Tooth device that can handle the programming and is also a small tablet. I don't even care if it has cell capabilities unless that is a prerequisite for the Blue Tooth. Low cost is best. Thanks!

Wow thanks! That looks like a very good option and for a few bucks more I can get a 8". Can you vouch for the functionality of these for the programming on this controller or is that just an assumption because of its specs?

The programming Android App needs very little resources, any android tablet could run it.

Now I do not know if the Android App is available from the App Store, this would have to be confirmed by the Developer.
If the App is on the App store, then you download it directly from the App Store on the Tablet.

If it is not, then you need to download the App on the tablet using the download link and install it manually on the Tablet.

The thread below has the manual download link to the App towards the bottom of the page, under:

My new muxus v3 4t and A123 20ah battery have frozen up and shutter when on and will not go forward. Battery 82volt good no bms. Unplugged and plugged all connections. Voltage dropping at c.a. with throttle and or without.
Is this the alarm system with anti wheel lock shutter shutter without throttle mechanism. Have never hooked up GPS alarm system. I was rolling down the road notice I hadn't turned on my bike flip the switch try to give it throttle and with throttle dead so walked home turn on still sputtering lock up still sputtering feels dangerous. ??? Maybe reset alarm system ? Feels like phase wires I did wash my bike yesterday but Road it for 8 Miles afterwards no problems. I did keep most water off the controller Splish Splash it was a bath.
P.S. will do the other diagnosed tomorrow.

The alarm is very unlikely to be an issue. You can simply unplug it completely to verify.
If voltage is dropping under load, it can be a bad connection or a bad cell. A motor stuttering may also mean that halls are bad and/or, again, bad connections in halls and/or phases. The worst case is FETs are shot.

That sums it up. Thanks for the write up, Scrambler.
I'll just add that Bluetooth connectivity is pretty much the only requirement. I did find that Galaxy phones (any model) work very well, partly due to AMOLED screen which offers great picture in day light.

Working ! I have never hooked up alarm ect.
The thing just froze like touching phase wire and giving itself a short jerk of throttle pluses with locked rear end. There was with no throttle applied plus my c.a. was dropping voltage like the stock market. Freakie.
So my batties just burnt up might v1 5t last week and the controller was pissed about the new 4t and more amps. The controller took over and the C.A. being from Canada shut down the voltage the throttle was hiccuping on his own and the poor dump 24s A123 20ah has no brains (bms). Oh well. Let it rest over night and all is well.
Nobody's talking like a bunch of high school kids not ratting on each other.
P.s. the controller and throttle are female, the battery is all male, the C.A. is gender neutral.

I guess Justin has the last word, till we go to court. This could get Messi if we pop the covers after taking out all the screws.
Really why was my motor taking hiccups of throttle and why was my voltage dropping from 82 to 69 volts ? Then lock up ? But could walk it up hill 3 driveways down.
Will change out with C.A. v3 and throttle with brake, regen and 3 speed. And light ? Light hook up ? Best pickup spot?
Remember Canada gave up it's nukes ( USA's ) as soon they found out. I never wanted nukes either. Gave them up too.

My 18FET Controller in Phasor frame
I was able to figure out the correct hall and phase back in August and been riding her ever sense.

Its been working really good. I will post later some recommendations about how I set up the throttle using Cycle Analyst that I have found from experience riding from the last 3 months.

This thing is very Silent! The tires make more noise rolling than the motor.

Nicely done, Microbatman.
On this kind of a frame, I would even consider the possibility of taking the controller out of the shell and bolting the heat spreader directly to the frame using it as one big heatsink. That's only if you want to free up some space and really push a lot of kW.

Powervelocity:

I'm interested in thermal rollback that doesn't require a CA. Are temp sensors supported on your current controllers?
Thanks

Yes, on the the temp sensors. Can be added and programmed to trigger power rollbacks, etc.

Have you tried changing the settings and hitting that program button when you have the motor lifted and turning?

Any plans on working in the ability to add in temperature sensor data to the controller? Monitoring something like motor temperature might be a nice feature.
