    Sanyo 18650GA low voltage cutoff

    Guys, I know the recommended LVC here is 3,5V, so batt will bump up to 3,65V resting voltage. Could it be that this just doesn't hold through for this particular cell? I did a discharge from full to 3,5V on a brand new genuine 18650GA, only got 2292mAh out of it, instead of the rated 3450mAh...

    Legalize kit?

    Couple of weeks ago I came upon this old thread (I think), which had pics of a small kit which would take input from the throttle and pas, and output that as a single throttle signal. With a switch you could change the behavior from pas required to not required, and set max speeds. Something...

    18650 testing

    18650 cell matching

    I've ordered 140 cells - sanyo 18650GA. I plan to measure their capacity and internal resistance before doing anything with them. Should I match them on ir or cap? And should they be matched for series or parallel connection?

    AMC-600 - 4-30V source?

    I've bought an EMC-600 charger, and would like to add a V-A display. For this I need a 4-30V source, and would prefer this source to be internal in the charger. The fan runs at 12V I presume, so where could I tap into that 12V source?

    EMC1000 - 12V failure

    Hi all, I recently bought a second hand EMC1000 Charger. Label on the case actually says ELB110606001, but internally it looks exactly the same as the EMC1000. Anyhow, I wanted a little more feedback than the leds could provide, so wanted to install a volt-ampere meter. This needs anywhere...

    Common ground for handlebar controls

    I'm gonna run internal wiring through the frame for my handlebar controls (cruise button, 3 speed switch, throttle and CA) Can I use a common ground wire for these? Would mean less cable to run :D

    Waterproofing controller (possibly ideal product found)

    Hey ES, I've now officially read every thread there is about waterproofing electronics. Two things I've noticed: there seem to be a lot of people against potting the controller, for two main reasons: 1) Heat dispersion 2) Impossible to replace components when something breaks First of all...

    5v out for usb charging

    Our controllers all supply a 5v line for throttle and whatnot. Would these be strong enough to put a usb port on to charge mobile phone on the go?

    Torque arm installation

    I purchased a mac motor from cellman, with the ebikes.ca torque arms. Do I need the torque washers that came with the hub? (with the lip bent) If so, where do I put them, and lip in or out? I was thinking of putting them like this: Hub - Torque washer - dropout - round washer - torquearm -...

    Use BMS as on off switch

    Is it possible to use a bms to cut power to the controller with a keyswitch? EG: on key off, power to controller is cut, meaning zero drain, but bms is still capable of balancing the cells while charging. Possible?

    hidden system

    Hi, I want my commuter system to be hard to spot (theft reasons and other). Have a MAC 8T ready, which will be covered mostly by panniers. Would like to control via Lyens 6fet mini controller. 12S 2P lipo, with bms. Now, having a throttle or display would make it rather obvious. Was hoping to...

    Splitting a lifepo4 pack

    Hi, for my first build, a bought a lifepo4 pack 48V 20AH. This went reasonably well for some time, but the big lump of battery had nowhere to go except on the rear rack. This handled like crap, and actually broke the rear rack twice. Getting fed up with this, I bought a falconEV bag for in...

    Nuvinci N360 ratio?

    Trolling the web, but can't find the exact ratios for the N360 Hub. I know it's stepless, but need the correct min and max ratio to calculate the sprocket and chainring I would need. Also, what is the biggest sprocket you can fit on the nuvinci itself? Would use a cyclone 1200W to drive this...

    Sprocket choice for cyclone 1200W motor?

    Standard sprocket is a freewheeling 14T. Would like to replace this with a 10T, freewheeling is not necessary. Are there any options that fit the output shaft? If I'm not mistaken, it's a 20mm shaft with a keyway machined in. Sprocket should be 1/8 x 1/2, so I can run a 1/8 bicycle chain...
