    Need advice on battery pack build

    Hello everyone I have decided to come back to the e-bike world after getting continually harassed by police on my gas powered bike. I was just wondering if anyone had any experience with the chinese lipo cells that they advertise on sites like Alibaba etc. My idea was to buy some lipo pouch...

    RELIABLE e-bike setup

    I have been into e-bikes for over 4 years now and I think that the longest stretch of problem free riding has been like 1 month! I realize that when you run 72V and higher the bikes become a little bit unreliable. I went out and bought one of those Gio 800W scooters because I wanted something...

    BRING BACK THE CRYSTALYTE X5300'S!!!

    Hey everyone I think that we should all send e-mails to Crystalyte asking them to bring back the 5300 series of motors! I think they are so much better for people that like to run high watts through their motors and they should never have stopped production! Maybe they could even offer the...

    Hub motor recommendations

    I recently purchased a Gio 800W scooter because I want to build a sleeper scooter. I am going to install a Lyen 12fet programmable controller and most likely re-configure my 72V LiFePo4 pack so it will fit in the compartments. I want to run this thing at around 65A continuous or maybe more...

    BMS balance leads

    I have started on a new project and I have a question regarding the BMS. My battery is going to be split into 2 parts and it is going to go in 2 separate locations. I will need to extend half of my balance leads to reach the front pack. Is it important that my leads be all the same length...

    18fet Lyen problem

    I recently took my Tidalforce bike with a 72V Headway pack, a HS-3540 motor and an 18fet Lyen controller for its first ride. It topped out at 75km/h and was pretty fun. It could use a little more power I thought so I tried to re-program it. First I used the Lyen software and I put something...

    Magura throttle with current limiting

    Hello I am going to get a Magura throttle because I am sick of replacing the cheap plastic twist ones! I read that you need to add a resistor to get proper throttle modulation but what about if I am running the current limiting throttle? (the one that goes through the cycle analyst) Do I still...

    Controller programming help

    I have never tried to program a controller and I think I will make an attempt on my new 18fet Lyen (if it ever gets here). My battery pack is a Headway 24S2P pack. I will be running a modded HS-3540 and was wondering what settings you guys would recommend. I will be using the 3 speed switch...

    Dirt cheap inductance meter

    I just thought I would pass on a link to this dirt cheap inductance meter I just bought on ebay. It ended up costing me 6 bucks plus 11 shipping! It is useful for testing the windings on hubmotors and many other things. I cant believe that they can sell them this cheap!! :mrgreen: :mrgreen...

    Lipo Charger Question

    I was just curious if anyone has any experience with this charger. It says that it is able to charge 4 Lipo packs separately all at once but I remember that there was an issue with a charger like this where it required some major modifications to charge 4 batteries at same time. I believe that...
