I have used the bike for over a year now and the plugging and unplugging doesn't bother me, but I am sure it would be a pain to some folks. I still like the flexibility of being able to change the pack configuration. I can run 10s6p, 15s4p, 20s3p, 30s2p and it only takes a minute or two to...

I saw that diagram and can't remember if I tried that or not. Jonathan, Would you let me know if you have an analog or digital Clyte controller. Also, did you wire it the same way I have listed. I ran mine at 36V with a hard limit of 25A and it seemed fine until about mile 5 and that was...

Anyone have the definitive, "How to hook up a Clyte Analog Controller to the BMC motor". I used the pinout from Doug which is: Phase Wires: Controller Motor Yellow Blue Blue Green Green Yellow Hall...

Same thing happened to me on Friday. Worked on the bench and then went bad in the first hundred yards of test ride. I replaced the wires on the motor and it is working fine now. Steve

The equivalent MPG can change drastically according to your location. In Tallahassee, FL we pay 14 cents per KWh for residential power and there are no off peak rates. The 185 Wh/mile seems a bit optimistic to me considering my electric bicycle use 40 Wh/mile. There are also inefficiences in...

It works just like you drew it up. With the knob turned all the way CCW I get my normal 60A limit that I got by modifying the shunt. If I turn the knob all the CW, the current is limited to 20A. This is exactly what I wanted, thanks again. The black wire has 51K Ohms of resistance and...

Great, thanks again for your help. I couldn't find a 150K, so I was going to put a 100K in series with a 47K and hope that 147K was close enough. I will post my pictures when I am done, so if there are anymore schematic impaired members you shouldn't have to answer this one again. Steve

Thanks for the help. I looked at that diagram for hours last night and just could not get it to click in my mind. Anyway, after your help today I think I have it. Can I just get the following parts from a local electronics store: 10K Linear taper potentiometer – ½ Watt 100K ½ Watt...

I replaced my FETS with 4110’s and added solder to the shunt which increased the current limit to 60A. I am currently using a CA to limit the current, which works but it is difficult to get it to work smoothly. I would prefer adding the adjustable resistor network that Richard describes...

Sorry about the late reply, I haven't been on much lately. Anyway, I did make all the wires the same length to keep the resistance the same. I doubt it makes much difference, but my Dad had some real world experince with 12V batteries connected in parallel where batt1 connects batt2 connects...

It is a very comfortable bike for commuting. I thought having so many connectors would be annoying but it only takes a minute or two to unplug or plug everything in. I also like being able to get to each cell if needed. The only problem is that you can accidently plug them in the wrong way...

I second the power supply suggestion. I have been using three of the 20A - 100W models for about a month to charge 60 cells. Only takes about two hours to get the packs full after an 80% discharge. I updated my build thread to include pictures of my charging setup. Just go to the last...

Finally, here is the charging operation in progress. Works great. I did monitor the setup several times and found that if I watched one cell, it started at about 1.2 A and maintained this through most of the charge until it drops way off after about two hours. The power supply handles this...

I am charging the above setup with three of the 100W power supplies I mentioned above. Each power supply gets 20 cells in parallel. I adjust the power supply voltage to 3.60V and plug in the cells. It takes just over two hours for all cells to be fully charged from my normal 80% discharge...

Just wanted to update my configuration. One of the reasons I wired each cell individually with the APP connectors was so I could easily change configurations. I started with 60 cells in a 15s4p configuration, but have finally settled on the same sixty cells in a 20s3p arrangement. I can...
