    Nucular electronics - complete kit for ev!

    I think he means that it does not work like those shitty 18fet infineons which overshoots phase amps way over limit on start. :D

    Brushless motor efficiency

    IS there some point to peak 3kw motor with 25kw. It saturates propably in 10kw. So anything after that is just pushing more amps that generates only heat with no added torque / performance?

    Toyota Prius A/C Compressor Motorbike: The Bike of IPM Motor Science

    We are making E-Kart prototype with IPM motor. We need the best available acceleration from 40 to 60kmh, top speed would be 80kmh. Is it better to gear it to 80kmh without Flux weakening or gear it to 40-50kmh and apply field weakening to go up to 80kmh. Which scenario has the best acceleration...

    Do you have controllers in stock and any estimate when you release 18 or 24f versions? Before next summer?

    Nucular electronics - complete kit for ev!

    This can't be run with those LMX/Denzel motors? Like these: http://www.eastgem.net/d4500.html Is it cause high impedance or rough signal in these motors? EDIT: Oh I saw this :"Hall filter programmed in my controllers." So it could work now? Even with 10kw peak power? I could test it on my...

    QS 3000w midmotor

    I would need to pair 428 sprocket with this. QS does not supply the anymore. Does anyone have a source?

    Lipo Wiring Parallel and Series Simultaneously

    Yeah I think the bulk charger could be the best option. BMS-Battery has some options for 20s but I'm not 100% guaranteed of their quality. Would rather take 2x meanwell in series if someone could do the wiring for me. :)

    Lipo Wiring Parallel and Series Simultaneously

    Paralling balance leads works amazing. I have 6 pieces of 25c 5s 5000mah turnigys that are 3 years old now with over 200 cycles. We have used them on my son's Electric Motocross bike and on ATV. I have every time charged them on 6P paralled on balance and main wires with iCharger. The cells are...

    Lipo Wiring Parallel and Series Simultaneously

    I'm using currently iCharger to balance charge my 20s16ah battery pack. But its a bit pain on the ass to disconnect 5 wires and connect 10 wires to iCharger (5 main and 5 balance leads). Would there be some way to balance charge this pack without BMS without disconnecting any wires? I do not...

    Cycle Analyst V3 preview and first beta release

    I had disaster day in our garage today. I connected the three speed switch to CA instead of potentiometer. Aux Digital and switch are original Grin technologies and are connected to y-plug. After setting up the correct values to analog output to switch between 25kmh, 40kmh and 80kmh speed limit...

    Cycle Analyst V3 preview and first beta release

    Is it possible to enable the option to choose AuxD input function based on preset? That would be nice too. I could switch presets by 3-button switch and use AuxD for levels? Would this help for "bizarre effects on operation because of the interpretation of the other releated settings"?

    Cycle Analyst V3 preview and first beta release

    Thanks. I get it working but I think I like 2 button digital Aux more paired with 3-speed switch. Would this feature be hard to apply to CA software: When holding aux up or down it would cycle through AuxD->Functions instead of going lowest or highest parameter of current function. When driving...

    Cycle Analyst V3 preview and first beta release

    I have weird problem with self wired Aux potentiometer. When turning the pot display brightness goes bright and beyond (text disappears). It does the same even I disconnect Digital Aux Button. I tried dozen of deadbnd-settings but display does adjust every time so bright that text disappears...

    A minimal Q76 offroad build

    Those 4s and 6s packs with 16ah handles twice the amps compared to 20ah packs (icecube57 tested 5c peak ability to them). They actually have two pairs of 8ah packs in parallel inside the pack instead of 1 pack like on 20ah. I have run 20s 16ah pack with heavy use on 100A peaks and they perform...

    A minimal Q76 offroad build

    I made very similar build on Q76 with exact same Multistar setup than you and Sabvoton 72150, Cycle analyst etc. My build weight exactly 40.0kg (88 lbs). I have Mxus v3 3000w on 24" 46mm wide DH rim with 12g spokes and Maxxis Holy Roller 24x2.4" weighting 11,5 kg (25lbs). That is about 4kg...

    MXUS 3000 Hub Motor - V1 V2 V3

    In other league. Kelly is worth about $50 (unit price when ordering 15 pieces). My 5 year old son has KLS7230s on this modified Oset and it gets warm on his usage. I could not imagine using it myself.

    MXUS 3000 Hub Motor - V1 V2 V3

    Infineon sinewave and Sabvoton 72150 has been quiet on me. At 50kph chain noise is 10x the motor noise.

    Any experiences of the E-Kross company?

    Even it would be safe I would never pay with those options to anyone outside of borders.
