    Hi Guys, I have been researching building a pack from the panasonic range of 18650 cells so this thread has been a good read. I have come across panasonic (claimed) NCRB cells with internal protection. See below links...

    Testing Xlyte HS2440 Motor Wiring

    Having no luck in working out the issue with a crystalyte HS2440 motor (See Thread http://endless-sphere.com/forums/viewtopic.php?f=30&t=39530) I have since purchased a Bafang BPM 350w motor to use instead and although I have had some issues with the Bafang motor (Internal slipping) when the...

    Bafang BPM Motor internal slipping

    My understanding of how geared motors operate was not correct when I diagnosed the problem being a slipping sun gear. After sitting spinning and watching the various parts of the motor for a good period of time and getting my head around it, I have come back to the original conclusion that the...

    Bafang BPM Motor internal slipping

    Good to hear from a local. I don't see to many ebikes around newcastle but hopefully things will change. After marking various internal parts with marker, reassembling motor and powering it to slip I found it to be the sun gear rotating on the axle. I have now brought two different motors...

    Bafang BPM Motor internal slipping

    Opened up motor today and everything looks intact. No chewed gears so i think a slipping one way bearing is the problem. I'm going to mark the sun gear as suggested by Knoxie and power the motor just to check. I have contacted BMS battery to see what there input is also. Where can I buy a...

    Bafang BPM Motor internal slipping

    Clutch/freewheel/oneway bearing. Whatever you want to refer to it as. The mechanism that engages the motor to the gearing in fwd but allows the hub to freewheel with no power applied. Motor is running in fwd (correct) direction. It is a disc motor so you can't get it wrong. The motor/gearing...

    Bafang BPM Motor internal slipping

    Hi Guys, After receiving a dud crystalyte H series motor from crystalyte I decided to go back to the geared option as I have had no issues with my BMC and like the light weight and small size of the geared motors. Not requiring a high power output I decided to go for a Bafang BPM front motor...

    Bafang Bpm, how many RPM?

    Hi Guys, I just recieved my BPM motor from BMS Battery. I ordered the 36v 393 front motor. My motor code is 16(9). Having read this post prior to order I was expecting a code 8 motor. I emailed Bafang directly about the unloaded RPM of a code 16(9) motor and they responded with the following...

    Crystalyte HS2440 Disappointing performance/noise

    Thanks for the input. The battery pack is sound with no problems with output. Yeah I went for the 2440 as I did not require a high power motor but wanted good torque and the price was much lower than the BMC. The 2440 in a 20" suited my application as the specs indicated it would give me the...

    Crystalyte HS2440 Disappointing performance/noise

    A CA was hooked up with the infineon controller only. More Volts? Will this change the motor characteristics at slow speed? Noise etc. I know these motors like more voltage but the intended use for the bike does not require a high speed (30kph). Cheers Toby

    Crystalyte HS2440 Disappointing performance/noise

    Hi Guys, Recently fitted a HS2440 to a project bike. The motor is laced into a 20" rim/tyre and I'm running a 36V headway pack. I have tested the motor using two different controllers: crystallite sensor less 25 Amp and an infineon 35amp 12 FET(motor has halls fitted). The performance is very...
