It would appear that I was wrong about the 13S10P as it is only a 13S9P 18Ah pack: It would appear that cheap packing pieces produce more profit for the seller than fitting another 13 non-genuine cells! Alan

They appear to be using YG INR18650E 2000mAh cells, probably in a 13S10P configuration: Check out this thread on the Golden Motor forum for further details. Alan

The 20" Magic Pie can be fitted with 16" motorbike tyres which should be heavier and also harder wearing. The USB cable can be used to slow the acceleration down to prevent/reduce wheel-spin on take off. Getting the software to communicate with the controller can be very difficult if you don't...

I totally agree with Drunkskunk, if you have a direct short on the battery lead it will be very obvious: A direct short works just like a pacemaker - it instantly starts your heart pumping again. :shock: Alan

PD_282 is the wrong program for the Vector controller. I have uploaded the driver and programming software that I used with both Windows 7 and XP to a Dropbox folder that can be accessed here. First you’ll need to install the correct driver for the USB lead (download and run CH341SER.EXE in...

Although 40mA may seem insignificant, it's still more than enough to kill a fully charged 16Ah pack if you should accidentally leave it connected and turned on for three weeks. 16Ah/0.040A = 400hrs or 16 days and 16 hours. Alan

Kevin, A bent axle is extremely unlikely, but if it was bent, it could not cause the hub housing to wobble because the axle does not rotate! Alan

I wouldn't be so sure about that. I did some rough calculations on my motor and worked out that the force from the axle trying to spread the gap would be at least 500Kg (1100lbs)! (That was with a measured force of just 15Kg (33lbs) at the tyre.) Rear drop-outs are more vulnerable to damage...

My thoughts exactly. Just need to sort out a 20" Magic Pie. Or modify the front forks to take a disc brake and this high rpm 16" Magic Pie: Alan

Just a suggestion, but have you considered using a pair of identical cables in parallel and just put the clamp on one of them? You should be able to measure up to 800 Amps by simply doubling the reading on your current clamp. Alan

I think it's just an unfortunate mistake during assembly in the factory and they've somehow used a rear housing to build the front hub. They've used the correct end cover plate, and axle assembly, but got one rather important piece wrong! As these parts are assembled by hand, the occasional...

So long as the rollers and springs were refitted to take the drive load it should work fine, but don't think about using regen with it, or you will definitely be asking for trouble! Alan

Thanks for the reassuring response Fechter, and also the constant current suggestion, but I'm probably going to stick with the constant voltage set-up, as I think it will be easier if I want to include a switched or variable resistance for High or Low headlamp power without altering the...

It's a bit of a pain having to do in blocks, but if you can copy and paste, it can be done here: http://freetranslation.imtranslator.com/English-language_Finnish-Translation Alan
