    How to put 2 batteries in series?

    What about increasing the amperage on my Lyen controller instead of changing the voltage? Would that give me a faster top speed, or would it just accelerate faster?

    How to put 2 batteries in series?

    I have a Lyen Mini Monster programmable controller but I don't think it is rated for 96 volts. I bought the batteries about a month ago and they are great. I have them in parallel currently and I've never pushed them too hard. Besides the cutoff voltage for the controller that came with the...

    How to put 2 batteries in series?

    I have two 48 volt 20 amp hour Calibike batteries and was wondering how I could put them in series, but also limit the voltage going to the controller. I know fully charged they reach about 108 volts, but I would like to figure out how to limit them to a 72 volt setup without bypassing the BMS...

    Would this motor work with my sensorless Lyen controller?

    My small 250 w hub sensorless hub motor just grinded itself to a halt on Sunday, so now I'm looking for a replacement for my fat tire ebike. I have a Lyen sensorless controller and this motor seems to have a lot of wires coming off of it. Can someone help me decide if this motor would work...

    Putting a Car Horn on my bike?

    I bought a new frame bag from FalconEV which BTW is an awesome bag, but I put an additional 12 volt battery to run the car horns and motorbike horn in addition to the LED's on the frame, with 3 seperate motorcycle momentary push button switches. https://www.youtube.com/watch?v=PBu9S3C1H2s Skip...

    Is it possible to connect a BMS to 2 batteries?

    I used my Calibike battery for the first time today. Had to say pretty impressed so far. I did 25 miles in the wind today and it was still at 47 volts when we were done. Not bad for my Fat Tire Ebike. I reprogrammed my Lyen controller for a lower cutoff voltage, since these cells can be...

    Is it possible to connect a BMS to 2 batteries?

    Thanks for the help. I purchased another of the Calibike batteries and plan to sell my used battery on Ebay. Rafe told me to put the batteries in parallel to make sure they are charged and have the same voltage before putting them in parallel. Now I will have a 48 volt 40 amp hour battery...

    Is it possible to connect a BMS to 2 batteries?

    I Thought calibike was using LifePo4? That is what my other cells are made of, and to answer the question about my other BMS it was damaged making a wooden frame box and the company that sold me the battery sent me the wrong BMS and told me how to hook it up which ended up killing one of the...

    Is it possible to connect a BMS to 2 batteries?

    I just recently bought a triangle shaped battery from Calibike.com that came with a BMS installed. It is a 48 volt 13 series 9 parallel made of 18650 cells. My other battery is a 48 volt 15 series 10 parallel also 18650 cells. Is there a way of connecting these two batteries using the 14 pin...

    Putting a Car Horn on my bike?

    Yes. I even noticed a spike in voltage on my auxillary volt meter when I use the motorcyle horn. I guess if I want a louder horn I'd have to be comfortable with adding more weight. (Second Battery) :( And all it says on the horns are each are 60db 12 volts one high and one low.

    Putting a Car Horn on my bike?

    I have been toying around with a dual tone car horn rated at 12 volts. It works great when I hook it up directly to a 12 volt battery, but when I use my DC-DC converter from Edward Lyen the horn will not function. I have tried running fuses from 10-30 amps, but there is no difference. Other...

    Help I accidentally broke my BMS!

    Sorry all the cells except for 10 in parallel were reading 4.3 volts, the others were 0.0 volts. So I contacted the manufacturer and since I purchased a new BMS and charger they are sending me 10 of the same cells for free. In the time being I have removed the 10 cells and created a jumper...

    Will my motor work on this wheel?

    My hub motor came with a hub brake. That is what I am using for now. You have to be pretty careful though.

    Halloween Critical Mass Costume Ideas?

    Hey I was pleased with last month's turnout for Critical Mass and I'm even more excited for the upcoming one since it falls on Halloween. We are doing a costume party as well as decorating our bikes for the ride. Any suggestions of a cool costume are welcome.

    Help I accidentally broke my BMS!

    Well my charger blew up the other day when charging so I contacted the manufacturer and they're selling a new BMS and charger identical to the original, so I guess problem will be solved in two weeks. If anyone is interested in buying the New 12s BMS I have it up on ebay for $35...

    Help I accidentally broke my BMS!

    Alsmith wrote "You can always charge using that old BMS and take power directly from the battery bypassing the BMS- BUT you need to watch your voltage doesn't drop too far to avoid battery damage. This would at the very least get you mobile while the incorrect bms is exchanged." :D This is...

    Help I accidentally broke my BMS!

    I figured I would open up the vinyl casing to get a better look. I plan on wrapping it with a nicer fabric anyway. Hope this can help.

    Help I accidentally broke my BMS!

    I believe the battery is ballanced, but it is sealed in two layers of plastic wrap, so I can't tell for sure. There is one main negative and one main positive. I inlcuded a close up pic of the battery cable and the new BMS connection point.

    Help I accidentally broke my BMS!

    The old one is damaged. I could charge the battery, but if I tried to ride with the bms attached it would kill the power, so I'm not sure why. So I purchased the one but it has a 14 pin connector instead of 15. Does that mean it is made for a certain number of cells in the battery? I know...

    Help I accidentally broke my BMS!

    Here is the conversation I had with the seller when the BMS arrived. It was different than the one I had previously. Dear imotorbattery,I received the BMS today, but it is not the same as the one that came with my battery. Including the red and black wires it has 14. My battery has a 15 pin...

    Electric Bicycle Fan

    I was thinking about adding a DC fan to my electric bicycle for LSU football season, but am limited in knowledge about DC motors and what would be the best for cooling and not too heavy. Something that would run at 12 volts would be nice. I want the most powerful thing I can find because...

    Help I accidentally broke my BMS!

    I just bought a new one from the guy that sold me the battery on ebay. Thanks anyway. If anyone is interested in my old one I'll give it away for free!

    Help I accidentally broke my BMS!

    Yeah it is a very small scratch. I'm not sure exactly what it damaged, because it would not power anything on the bike. I peeled off some of the silicone to see what got scratched.
