    Help Picking a Sensorless Controller (Non-programmable)

    Ok I need a controller that doesn't require hall sensors (mine are fried, or wiring is shorted - don't want to mess with either way, hard to access). Also need something fairly cheap, and that will ideally accommodate both the stock 24V10ah and an upgraded 36V10ah battery (doesn't have to do it...

    Mystery Electric Bicycle / Moped / Scooter

    Some more impressions after riding it a little while: - Frame is just a little too cramped... Esp. if you're tall. I don't feel it much on short rides, but its noticeable if going more than 5mi.. if I could do it over I would upgrade one model and get the Voltage 500GT 3, which has a roomier...

    Two Stupid Questions re Lithium Ion Battery

    Thx everyone for responses. For those curious, the scooter is a little "schwinn 650" with 650 Watt Currie motor (got on craigslist for $200). It has a 24V 30 Amp Currie controller (http://www.monsterscooterparts.com/s500controller.html). The stock battery is an SLA pack made of two 12v12Ah...

    Two Stupid Questions re Lithium Ion Battery

    Hi guys, I have this Lithium Ion battery: http://www.bmsbattery.com/36v/17-36v-lithium-ion-little-frog-abs-shell-ebike-battery-pack.html It works great but I wasn't sure about the battery indicator (seems like it should read "low" more often than it does...). I tested it fully charged with my...

    Mystery Electric Bicycle / Moped / Scooter

    For folks who were curious... I got this bike/scooter, came yesterday... I rode it once for about 5 miles... Here are some first impressions: Good: - Neat looking and nicely sized frame, a bit thinner and lighter than a standard scooter but not miniature by any means - Good suspension. Ride...

    Another Possible Hall Problem?

    I don't know if the hall sensors work or not. It's that or wiring. I was doing the test wrong at first, but the halls failed to toggle as expected even when I did it right. I am going to move on to the continuity tests outlined above (thx NeilP) - - - Does anyone have any thoughts about...

    Another Possible Hall Problem?

    Thx for bearing with me... can you please read what I did, and if I screwed up, rephrase how to do the continuity test? I set it in continuity mode and tested between the different hall wires (not hooked up to anything except the motor, no power source etc.)... Everything read "0.F" except...

    Another Possible Hall Problem?

    Hi itchynackers thx for the advice, I do have a multimeter with continuity mode... Can you please rephrase where to place the probes? I think I follow that the basic idea is to test between the plug-end (easily accessible) and the motor-end... There is only one thick wire coming out of the...

    Another Possible Hall Problem?

    I redid the test just as above (thanks NeilP!). I was giving it about 4.5V with three AA batteries. None of the colored hall wires performed as expected when I turned the wheel. They were all at 0 or just a little over when stationary, and at most went up to maybe .2V. So it's either the...

    Another Possible Hall Problem?

    Here's what I just tried: I plugged the throttle in. Unplugged the hall connection entirerly. Then I tried doing the following with all 6 possible ways of connecting the three phase wires (yellow to yellow, blue to blue, green to green; Y to B, G to G, B to Y, etc...): 1) I turned the power...

    Another Possible Hall Problem?

    Hi guys, Here's the history: motor stopped responding, first intermittently, then permanently. I thought the most likely culprit was the stock controller, so I tried putting in a programmable Lyen: 6 FET 3077 Mark II Mini Monster LYEN Edition Controller. Problem is, still couldn't get it to...

    Possible Hall problem on MAC. Connectors, wires or sensors?

    Howdy. I'm dealing with a very similar situation right now, except its less intermittent at this stage... One thing that has been very helpful are the following directions to do a Hall Sensor test (you don't have to tear things apart really, but you do need a voltmeter)...

    Mystery Electric Bicycle / Moped / Scooter

    Yah it sounds high... The battery type is "Gel Cell Sealed" - that's basically just SLA right? They do say "Battery Life: 1000 Full Charges" ... From what I gather about SLAs, it usually ranges from 300 cycles to 800 cycles depending on whether or not you baby them...

    geeeyejo1 Thanks man! That was the best advice I've heard yet. I'll look out for what you mentioned and see if they have a used one. In other news, I finally found some videos of not quite this model but a similar one by the same manufacturer. eAAGs2EDyf8 gIXO94lo27I These guys sell them on...

    Mystery Electric Bicycle / Moped / Scooter

    Thx dogman - exactly right and good advice... same rules apply as all electric bikes... all eBikes are legal here in FL wherever normal bikes are found, as long as they go under 20mph... I definitely get the sense that ranges tend to be overstated... I would hope for a bit more than 10 miles at...

    Thanks guys for your thoughts. This forum is cool. Any suggestions for how I can gauge quality (besides the price) would be appreciated. Anything I can ask the dealer or manufacturer that you can think of? Dauntless: it's not an XB clone... that page has a typo in the text. If you look at the...

    Hi guys, I'm sorry for a bit of a double post here... this thing is in a weird class between bicycle and scooter (technically an electric bicycle) so I'm posting in both boards... Here's the link: http://voltageelectricvehicles.com/vehicles.html It's the one on the bottom, the VM-500GT2 by...

    Reviews and Modifications of ebike model: XB-310Li

    Here's something interesting about this bike: X-Treme Scooters have apparently switched to a 24V LiFePO4 battery. Not sure what the current rating on it is. Sticking with the 24V is a little underwhelming, but then again its nice that their stock/replacement batteries will have the longer cycle...

    Reviews and Modifications of ebike model: XB-310Li

    EugeneM has been kind enough to look at my various options. He's found some "red flags" in the stats from the evlithium.com battery above (http://evlithium.com/html/Lithium_Battery_Pack/154.html)- some things don't quite make sense, and the cycle life is too good to be true. Here's part of his...

    Reviews and Modifications of ebike model: XB-310Li

    FYI, evlithium also have a LiFePO4 option: 36V8Ah little frog battery. Price is $228, so the total cost with shipping is $348. They don't have this listed on their website for some reason (evlithium.com), and the person I'm in touch with actually advised me to go with the non-LiFePO4 option. Not...

    Reviews and Modifications of ebike model: XB-310Li

    So, here is my question: I am trying to decide on a replacement 36v10a battery, and I'm considering LiFePO4, even though SergeTruth got one of those from BMS (in 24v10a) and it didn't work, "probably because of too little current." BTW - I'd probably want to use these w/the stock controller...

    Reviews and Modifications of ebike model: XB-310Li

    Have a few things to report and maybe a question... First the report: 1) I just killed an almost new 36v10a Little Frog battery by accidentally discharging it completely... like 101% completely. They aren't kidding around when they suggest against this in the manuals. It died in the middle of...
