Re: KT motor controllers -- Flexible OpenSource firmware for BMSBattery S/Kunteng KT motor controllers (0.25kW up to 5kW

Looking for a small controller compatible with this wonderful firmware. It is for 750w motor, replacing stock controller of Size L113 x W67x H56mm. It must be very close to this size as there is not much more room in the frame. It seems all the KT36 one's are too big or too underpowered. Something t...

Re: RV: DC Power Distribution

At such a low voltage, you're amperage will be quite high if you are trying to move any decent amount of power. That's going to take some large cable to pull off if you try to do it at your DC voltages. If possible, tieing everything together with 120v AC would be much cheaper for cable, but it does...

Re: jonescg's NEW electric racebike BUILD thread!

Love this build, and I'm extra excited to see how it goes because I have a CRX to electrify as well :D

Monitoring cell temp + bulge?

Ive been playing with the idea lately of droppign a thermistor between each cell and on the ends of teh pack to measure cell temperature, which seems like a decent idea. The other idea is to use a felx sensor on each side of a LiPo pouch cell to try and detect a bulged pouch, though I'm not sure how...

Brushless DC without permanent magnets

I was reading a tesla motors blog post about brushless DC versus induction motors ( http://www.teslamotors.com/blog/induction-versus-dc-brushless-motors ) and remembered that the powerplants I use at work have a somewhat similar setup to the AC induction motors. Granted, they are high voltage AC alt...

Re: Thinking about electrifying my old freeride bike

Do bear in mind, Isn't the cromotor a 150mm motor? Bet that bike is 135mm wide. I agree with the others, unless it's got wide dropouts, looks good for a 135mm motor with some balls, and the 40 mph club. Just how steep is that steep bit? 10% is doable by ordinary cheap stuff, like a typical dd kit o...

Re: Thinking about electrifying my old freeride bike

It is not a Freeride bike, it is a DJ. The frame is stiff enough to build high power. It will lack the rear suspension if the streets are less than perfect. Nice triangle space to neatly fit 20s 2p of Lipo, enough to do your 17 miles target range very fast with a cromotor in a 24in wheel. I believe...

Yes it will be. Looking forward to it as I hope to apply what I learn to converting my CRX to electric with more of a DIY approach versus droppign in a warp9 like most do.

Thinking about electrifying my old freeride bike

After doing some pondering, I think my old freeride bike would make a great starting point for my first ebike build, especially since I haven't (ab)used it properly since 2004. it's got super thick horizontal dropouts with built in chain tensioners. the rear chainstays are nice and wide and the fron...
