Re: Replacement Hall sensors in BLDC hub motors

This post comes up a lot when searching for hall sensors. So bump this up to the top for shitsngiggles. Question is, how much out of spec is doable when it comes to Hall Sensors? I try to get as close as I can to the SS41, so even though the first one, on the left is cheapest, I dont think it would ...

Re: Cheapest Active Cell Balancer Project

For a 10S5P at a cost of say $3 which is the cost of the MPZ307 alone its going to be $150, judging from Digikey.CA's website, more like $5 for each balancer. Easier for me to just buy a BMS from Besttech. It is a very interesting circuit you made there and I am quite impressed by it actually.

Re: Soldering novice: charger wire to BMS board

Maybe you have a 25W iron and you need a 60W iron. Once the iron is up to temp, any solder should change color and flow easily enough. If the hole in the pcb is not melting by sticking the hot irons tip in it then I am not sure what else there is to do without pictures I guess. What I'd do is get a ...

Re: Another bicycle rim almost toast

Another bicycle rim almost toast

Noticed today while guerilla charging a spoke busted the the Crystalyte rim (a tad towards the hub) I got two used motorcycle rims in front of me 16 x 1.60 steel - I have a tube and Shinko tire for it. 18 x 1.85 alum - Ordered spokes from Greentime so perhaps a month wait. Local spot can cut and rol...

Re: Statorade vs generic Ferrofluid?

You can only buy that Ferrotec APG1110 in mass quantities is my guess. Just buy from Grintech at www.ebikes.ca so you know its the real deal, been tested and wont harm your motor.

The only generic mxus motors I see is that seller that uses the C&D graphic and mxus label. Never really paid attention to their prices, compared to mxus themselves. Thats where I bought my 3kw v2. Time to buy some samples.

What about compartment safety?

I would buy that because its so light, but I'd worry about safety with other vehicles on the road, plus I wouldnt want a vehicle that looked too odd, rather have something that blended in nicely.

Your battery is going to be too large for 40-50mph and 75miles.

Good DH frames are made to ride that speed, down wild mountain trails. Don’t worry, the bike is capable. The rider is the only concern.
