    24 FET Infenion Hall Problem?

    I purchased a 24 FET from Cell-Man probably about a year or so ago. I had problems with it, shelved it, and never used it. I contacted him when I first got it, he said the hall/phase combo is wrong and left it at that. It acts EXACTLY like a hall is out, but the motor test fine, the hall wire...

    HP ESP120 48V (51.4V) 57A 3KW Server Supply Thread

    Here's a place to discuss the HP ESP120 server power supply. Modifications, uses, sources, etc... Throw it in here! I got only one to mess around with. These claim to require 200-240V input, at 20A! I will see if I can get it to power on at all off 120, but it would take at least a 30-40A...

    iCharger 106B+ 'Connection Break Down' (Over Voltage Repair)

    I just received a used iCharger 106B+ from a forum member, and its saying 'Connection Break Down' on anything you plug in. It's reading the cell voltages, and WILL go into discharge modes, but the current stays very low and it never does anything. Any ideas whats going on? Its reading the...

    1/8th Mile Times For Higher Power Bikes?

    I know Doc was at the track a few times, but who else has taken an e-bike to a track and has some real numbers? I did two runs on the iOS Dynolicious App, since one was slightly uphill, and one was downhill. Starting and stopping in the same area, roughly a constant grade the duration...

    E-Bikes and Suspended Licenses in NY.. (DWI)

    A fellow co-worker happened to get a DWI fairly recently, and its looking like he will no longer have a license for 1 year. His lawyer claims e-bikes, or any form of assistance of any kind on a bike, is illegal. The law really isn't terribly clear anywhere, and most things I read contradict each...

    Modifying A 48V Controller For 24S...

    I got a cheap, small controller, thats rated at 48V 20A, '350W', 6 FET... I would like to carry a small controller that will limp me back home at something like 2KW. It takes about 2KW to cruse at 40+, so it would be nice if it could handle that, which at its stock 20A rating, I wouldn't even...

    Help Me Adjust The LVC On This Controller...

    Does anyone know how to lower the LVC on this controller? Its a 250W 36V 6FET BMS Battery KU63.... It was supposed to be a 24V version, but this is what was received. BMS Battery is doing nothing about it. LVC is supposedly 27.5V, it needs to be around 20-21V... Excuse the mediocre images. All...

    Are My Halls Bad?

    I was messing around in dirt on my bike, lugging up some steep hills. The motor wasn't really very hot, and I was taking it easy for the most part. I was only out maybe 10 minutes before I turned around and headed back home. About 1/2 mile away from my house, the motor cut out at full throttle...

    System Efficiency Vs. Speed

    I'm currently running 24S2P of 5AH Turnigy cells, with a Lyen 12 Fet and 1000W GM rear hub. I've been taking my bike to work most of the time when its nice outside, set the cruise to WOT with the speed switch on 30% throttle. Average speed is around 13 MPH, and I used 146.4Wh going to work...

    How Hot Can A GM Hub Get?

    Running 70A @ 88V into my rear Gm hub makes it quite toasty after a few miles of WOT, into regen, back into WOT. About how hot can the external casing be before I should be worried? When I got home, it was too hot to touch, probably 180ºF... After I found a battery for my meter, I measured it...

    Best CHEAP Hub Motor Kit?

    I'm looking for a low end e-bike kit for a co-worker. Only really needs to go 10-15 MPH, power isnt a big deal. 500W is fine. He probably wants to run it off 2 or 4 6S 5AH Turnigy Packs... 22.2V or 44.4V. What about the cheap kits from BMS Battery? Something like this...

    Are ZIPPY Flightmax packs the way to go?

    Im finally getting around to getting new batts for my e-bike... And two of my friends have essentially exactly the same setup, and need new batts as well. What it looks like were going with is 2S4P of the 5000mAh 6S ZIPPY Flightmax LiPO. I would like to run at least 60A into my rear hub, so...

    Single Speed Cruise Switch?

    What would be the easiest way to make a switch that would override the throttle and go a preset speed, say 8MPH, or about 1/4 - 1/3 throttle on a hall effect throttle? It would need to be very precise and reliable, as it would be placed on 3 bikes to go the same speed without using the throttle...

    How Bad Is WLA For E-Bikes?

    I happen to have a week old U1P-7 Everstart Lead Acid battery from Wal-Mart that I dont need for anything else. Me and my two friends are in need of new batteries, and cant find anything 48-60V in the 15+AH range for under $500... These are $25 each (+ a $5 core charge) and readily available at...

    Currently me and two friends are running 4x 17Ah 1/2U1 SLA cells, and we only got about 8-9 Ah out of them new, averaged about 6-7 Ah after a few cycles, and we get about 4Ah now... So, were looking to hopefully replace our 62lbs of SLA that gives us 48V @ 7Ah with something a bit lighter and...

    I couldn't find any burnout videos on YouTube!

    There really is no even decent electric bike burnout videos on youtube, so heres a semi-decent one. I can get more smoke out of it if I try and run it fresh off the charger. It smokes more on the center of the tire back when it had tread. Theres lots of weight over the rear tire with those SLA's...

    Hybrid Electric Combo?

    Its very possible and somewhat likely that im going to at least try to make a small generator that can power my bike at lower speeds, say 10mph or so. Im looking into a small hobby motor of sorts that can run on 87 octane pump gas and can turn a 48v motor at the appropriate speed to generate say...

    Ecrazyman controller issues?

    I purchased a 25A 600W 48V ecrazyman controller off ebay about 2-3 weeks ago, and just got it in today. Its was supposed to replace the stock 1000W 48v golden motor controller that my friend cooked. I replaced the throttle 3 pin connector with a female one to work with my throttle, it had a...

    I purchased 3 GM 1000W 48V rear hub kits about two weeks ago. Last week, my friend cooked his controller. He had a poor install, and one of the phase wires was falling out all the time as the controller knocked around. Well on about the 3rd time it did this, he reconnected the wire and the...

    What can be done to this 15 FET controller?

    I got this controller with my 48V 1000W GM rear hub kit. Is there anything that can be done to this controller to increase top speed? I already modded the shunt, and beefed up the traces to the FET's. Any help would be appreciated.
