    Best ebike Battery for Consumer not Hobbyist/tinkerer?

    As long as the motor and controller are rated at the same voltage as the battery, a larger capacity or higher discharge battery will only put less stress on the battery or give more power over time. This will help the battery last longer given the same discharge profile.

    Advice on full e-bike build for someone new to the field

    Trigger, I have a bbs-02 750W in a 29er Fuji frame. One main problem I see is going to come from your brakes. When you are negotiating any off road terrain you will need motor cut offs. I noticed that earlier in you stated that you have hydro brakes. You will not be able to add the manual...

    putting 26" hub motor on 700c frame.

    It would depend on the winding of the Hub Motor. With a larger diameter wheel you will have more top end speed but less torque and greater demand from the battery. There is a great spoke size calculator on ebikes.ca.

    LiPo charing is a PITA

    It been covered many times but anyway here it is again. You have to be extremely careful that the charging harness cell voltages are very close in value before connecting in parallel so that they don't try to equalize cells when connect them together. Never parallel the charging harnesses of...

    Calibike 48V 15ah battery

    I wrote Rafe an email about a week ago and I did not get a response back. I went back to his website today and tried again and he emailed me a phone number to contact him. He explained that the BMS has a known issue with being turned on with a load attached. He is going to email me with some...

    Calibike 48V 15ah battery

    I am having some trouble with a battery pack from Calibike. I just purchased a 48V 15ah pack. This battery has two connectors, one charge port and a pack power, and a switch on it. I assume that the switch goes to the PCM. The pack shows 54.2V fully charged with the switch on and 49V with...

    Overdrive 36V 500W yescom kit

    Thank you all for the input. I have no desire to do 40mph and I always pedal up to at least 5mph before applying any power. At 25mph I average 500-700 watts depending on wind and my desire to pedal, which I do all the time. I was just looking to get up to speed faster and improve short hill...

    Overdrive 36V 500W yescom kit

    I have been running this kit at 48V 20amps on a HK Lipo pack of (12S2P) for a couple of years now and I would like to up the ante. I was thinking about changing out the controller which I am almost certain is a 6 fet for a more powerful controller. I am thinking about a infineon 9 or 12 fet...

    Buying my first kit

    I believe that your wanting to try a cheap first kit to build has been shared by all at one point and time. I would suggest that you get a current limiting system like the Cycle Analyst V2 or V3 or other manufacturer that will allow you to restrict the power automatically. You simply set the...

    Thinking about building a Fat-Tire E-bike.... need some help

    I agree with dogman. I ride the Boris X9 fat bike and it is a pleasure at 12-25mph on trails but it is not built for speed on those low pressure tires. It is not electrified, just stock, (lighter). If you want a bike that will go 35+mph get a good downhill bike with superior brakes and...

    need battery help

    You have to consider a lot of factors prior to sizing you battery. If you want the standard 36V using Lipo you should use 10s which would give you 37V nominal, 42Vpeak and a Low Voltage cut off around 32-30V. Lipo can be dangerous and takes special precautions like a battery monitor during...

    help trouble shooting em3ev kit

    I agree 3.7v is way too high for a cut off. Voltage sag will cause you to cut off prematurely all the time. 3V would be much better. I have a similar setup and my controller had no 5V on the throttle. Justin has some good troubleshooting tips on his site. ebikes.ca . Check to see if you have...

    Hello, I have a EM3EV mac kit that has the typical bulky connectors and a nice connector for a cycle analyst ad a PAS. I would like to rewire the kit to a more unified design and move the wheel connections closer to the wheel for easier tire repair and removal. Does anyone know where the best...

    What tire can cope the ebike punishment?

    I have had many of the slime tubes and different tire combos, Kenda, Maxxis, Continental and still had plenty of flats. I have never had a slime tube save me, just adds mess to the tire change. The longest running combination for me has been a Walmart Hutchinson lowrider tire 26x2.35 and a...

    The Cycle Satiator, universal charger for the enthusiasts

    I am charging to 49.8V at 7A and the charger reports 342 watts and 60-63 Celsius. This seems pretty hot. The ambient temperature is approximately 75 Fahrenheit I am not certain where the temperature probe is taking its measurement from but won't this have a degradation effect on the...
