I was going to epoxy my hub today, but after looking at it, I don't know if it will work. I forgot about the freewheel being in there an I just mistakenly remembered the gear press fitted to the hub, not the much smaller inner diameter of the freewheel being press fitted to the aluminum hub...

Yes, I am pleased. I pushed 3890 watts through mine today! At least according to my Turnigy 130A Meter. I think I heard my hub slip when I did a jack rabbit start(and unintentional wheelie!). The torque on this thing is incredible! Time to get that hub epoxied and get my other ebike(24v)...

Rode home from work last night, in the dark. This required that the headlight be on, which lights my way pretty well, but sucks power. Several times my controller went beep beep beep. Dunno what that means, but it stopped when I let off the throttle a little. 127.7Wh, 4.8miles 2.678Ah...

Just rode to work, but I forgot to reset the Turnigy power meter and odometer, so the tests below include the previous run above. Part way through the ride, I found the performance<->economy switch and switched it to p and things got better. Maintained 20mph with pedaling up a .75mile hill...

Just did a test run on my ebike, and it seems that the controller is the limiting factor. Even at 50V, the motor only assisted up to around 20mph. These measurements were taken with a Turnigy meter between the batteries and the controller. 77WattHours/1.9 miles with tough hills. 28mph max...

After looking at my ebike Heinzmann motor, I only found 2 conductors (red and black wires) coming out of my Heinzmann motor. I was hoping to find the thermal sensor wires that were mentioned, but I did not. Is there possible a thermal cutout circuit in the motor to protect it, or does my motor...

I see what you mean, but if you have the right charger, you can do up to 14S. Unfortunately, I did not get one of those. I got the turnigy quad 6s charger with the intention of making it do up to 24S like Doctorbass did. It isn't an easy mod though and you really have to know what you are...

Please tell me why. I am a noob, so I appreciate warnings BEFORE I do something stupid ;^) Thanks, hinv

I have an EVG 36V bike, and the stopping power is amazing. I was going to build a full suspension bike, but after getting LiPo's in this one, I am impressed enough with the stability and braking power that I may just just put a 5304 motor in front to get up to my 40mph top speed goal. The 36V...

I agree that it is probably not a good idea to parallel at the cell level while discharging because one cell would take down it's paralleled cell. What about at the pack level? I have some 4s hardpacks and was looking to run 12s2p for an EVG ebike that I have (hopefully it will take 44v). Is...

Thanks for the answers. I'm glad to se that I made a good choice for batteries. The cgarger will get me by too. Since I work on SGI computers, I have some 48v 1500watt non adjustable power supplies at the shop. Could I just use one of these and a battery medic while charging 12S3P? Will the...

I purchased a bunch(16) of these: http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=18631 because they were the cheapest way to build a powerful pack. My questions are: Should I expect quality problems from these Turnigy batteries? Was it wise to get the hardcase ones, or did I...

Hi, My son got a 250Watt scooter, but it came not working for $20. It appears that the last one in there mucked with the wiring on the controller. I took some pictures, but I'm not sure if it was right in the first place. Can anybody here tell me where things go on this, or translate for me...

Thanks to Doctor Bass for helping me not only finding this forum, but also giving me an idea on how to fix my EVG ebikes. I have the classic hub slip problem. I am hoping that the DP-420 epoxy will work in keeping it from slipping seing the kind of abuse Doc put it through. I tried JBWeld...

How about this? http://www.hobbyking.com/hobbycity/store/uh_viewitem.asp?idproduct=18631 Turnigy 5000mAh 4S1P 14.8v 20C hardcase pack (USA Warehouse) they are backordered, but at $23.65ea, and a special offer, these seem to be a good deal at $.319 per watt hour. Anybody know the number of life...
