Re: Grin Phase Runner / CA3 and BBSHD

For 74V, just set the Kp and Ki values to 1 and 10 (see image). You can use larger values for lower voltages. If by "judder" you mean where hitting throttle causes the motor to spin an full throttle and take up the slack in the drive train too fast, then user endrew's settings work great. You have ...

LiFePo4 A123 AHR32113 ultra B cells 4500mah each. These big cells are capable of 100 amp discharge over and over and 6c charge rate. The 30 amps we intermittently throw at them while riding is nothing and won’t even warm them up. Downside is one side is aluminum and that’s hard to spot weld to. The...

Re: Dave's 80:1 RC mid drive kit build log

Yes, 25R cells Are you sure? The 25r cells are rated as 2.5Ah. So the total capacity of the pack would have to be a multiple of 2.5. You wouldn't be able to get a 6Ah pack. I think Luna was making their mini cube batteries with either Panasonic GA cells or Samsung 30Q. Either way, just be careful n...

The batteries are Luna Cycle 52V, 6AH - 3 of them wired in parallel for both power and charge. Should be capable of feeding up to 150 amps to tap the full potential of the drive. The triangle is tight with only room for two so the third is under the seat. Wiring is all 10g silicone insulation flexi...

Can you actually attach files to posts here? I know you can attach images, but the PhaseRunner config file is of type .xml and the CAV3 config file is a HEX file.

Re: How to drive ebike using outrunner?

Several people have put a second drive chain on the left side of the bike, driving from the motor to a sprocket mounted to the 6 bolt holes for the disc brake. Obviously the sprocket has to be on a flange that moves it inward slightly, and the disc ends up moving outwards slightly, so it would depe...

Re: Building many smaller A123 packs (NO BMS) and add them together

2v Maybe the cliff that you already fell off of try 2 6v or zero. 3.50v -2 60v Typo sorry fixed. My bad, I misread the chart. Though if you were to pull 40 amps, the discharge curve sits pretty flat at 2.6 for most of your usage. Your alarm would be buzzing the whole time. I think 2.5 is right abou...

As for wasteful, the savings are still Al and worth is weight so it is not waste. As for engineering, hard core design often tend to be made from billet.

Re: Dave's 80:1 RC mid drive kit build log

But I think it's a pretty cool motor. I agree; but starting out with a 3.6kg solid billet of Al to form what is essentially a 400gm tube, rather than starting with (say) a ~1kg piece of tube , just seems wasteful. I can't see any good engineering reason for it. I'm guessing it's because you need an...

Re: Building many smaller A123 packs (NO BMS) and add them together

You would want the voltage alarms to be configurable. Those A123 cells cells are good until about 2 volts before they drop off a cliff. I would think most lipo voltage monitors would trigger much before 2 volts.

Re: HPC 1200w Bafang bbso2

Just a heads up, that is going to be a tough sale considering that a brand new BBSO2 kit is $400 from Luna. They will also "hot rod" program it to do 1200 watts for free. Anyways, best of luck. It's a great kit regardless.

Decided to convert my Phaserunner BBSHD bike to a single speed (28T front, 20T rear) for better chainline and simplicity. I've only had a chance for one test ride, but it seems like it can't take WOT off the line like it could before (36T front, 16T rear). That is really odd. So you have lowered th...

I'm curious how the stock BBSHD gets around this issue? Is it always slightly engaged or is the throttle programmed to engage at low torque prior to ramping up? Matt I hope we are talking about the same issue. My understanding is that because the Phaserunner is a current controller as opposed a vol...

Anyone here have a recommendation for dealing with motor "judder" or "stutter" that occurs with the BBSHD/Phaserunner combo when resuming throttle after coasting?
