Re: QS 3000w midmotor

CSC introduces its first electric motorcycle, the City Slicker, at $1,995 That is a great price, depending on battery capacity and power. The City Slicker has two operating modes, Power mode features a top speed of around 45 mph and Eco mode maxes out around 35 mph but gets better range. According ...

Re: Sabvaton & QS

I am setting up my QS205 with my Sabvaton 72150. I am using a 72v li-ion 18650 battery. Wondering if anyone has any experience and can offer advice before i start making all the connections and running the hall tests. Not really as it's pretty close to plug and play with the QS205. The only thing I...

Re: EM3EV battery doesn't discharge?

I'm just metering it from the discharge points (with the pack disconnected from the base/holder thingy). So just from the prongs that would connect to the base. The motor I am running is a gen 1 magic pie. I know the controller is designed for 24, 36, and 48v inputs. As far a a the battery voltage ...

Re: EM3EV battery doesn't discharge?

If your picking up that voltage, I doubt its the battery. What setup are you running on your bike? I know it seems silly, but is there any chance you have a 48v bike? I only ask because a lot of 48v controllers tend to cut out power at or around 42v. (your lithium battery is full at 41.7v and 3 SLA'...

Re: Help! Picking motor for my first touring build

@SirLongAss That bike looks great! What kind of trips do you get up to on that? Also... I didn't realize the BBSHD had a torque sensor... I thought it was just cadence! I get like maybe 50-70km on that bike with a 72v 20ah battery(1440 wh). It's really crap for rolling resistance. I'm pretty sure I...

Re: Help! Picking motor for my first touring build

Hey All, So, I finally decided to build an ebike. I've never owned one, so I think some of my questions come from a fundamental lack of knowledge. That being said, I'm very excited to learn and have already read so much about everything! Anyway, I want to build a bike that is _mainly_ for long dist...

Ive got $3000 in this build. I tuned the controller down so it only does a max speed of around 45 mph..which is plenty for me....I weigh 230 lbs and am 6ft 5 inchs tall.

Re: Cyclone vs bbshd

What exactly is good about Bafangs PAS system? I suppose it's more on par with ebikes that come with a mid drive from the factory. It makes you feel like you and the motor are 1:1. I think it's just software. It has a few features that are better implemented then you're run of the mill cadence sens...

Re: Cyclone vs bbshd

Hi, I own two bafang's and zero cyclone's (althought I will probably buy one at one point). From what I've seen by researching the cyclone for a while is that people seem to always struggle getting the one side of the mounting braket bent to fit their bottom bracket. Same bracket for all (I think It...

Re: Another Stealth bomber (clone) build

Dude you nailed it. So the issue was the hall test. When I wired up the bike the motor spun fine so I never did the hall test. As a result I think the although the motor ran it ran very inefficiently causing lots of heat. One I ran the hall test I hit the throttle and the wheel spun backwards, so I...

Holy shiz... Yesterday I the guy added that he got to cut off while the controller's cut off is 40V! meaning that they settled at 2.6V but the sag to get to 40V means 1.9V Just worry about the idle voltage.

Re: New Lipo accidentally discharged to 2.6V

I recommend putting somewhere outside and away from anything you don't wish to part with if you plan on charging it. 2.6v is salvageable if you can set a lipo charger to trickle charge it at 0.1A until it gets to 3.2v.

I perfer just to overcharge it until it explodes 8)

Re: running battery without BMS given incomplete charge/discharge

RC lipo has strict rules of management. You don’t need a BMS, you must be constant with the rules. The first rule: Never let RC lipo charging out of your immediate presence, unless they are in a 100% fireproof enclosed area. The 2nd rule: RC lipo must sleep about storage voltage and unplugged off a...
