    General failure issue

    Hi, I'm having trouble with my LiFEPO4 setup. Can you help me about diagnostic? I have 2x pack of LiFEPO4 48v/20A. Each pack have "pouch" cell of 20A each. These packs were purchased at eCity. Packs are connected together to give a total of 48v/40A. This summer, both chargers stopped...

    PING OR ECITY that's the question !

    Maybe I can share my life experience with ECITY. Mr. Xie has been very mannerly. I had good price and no problem with shipping. The LIFEPO4 48V/20Ah shows 53.9 volts on the Cycle Analyst. Inside the shrink you have a BMS, and many soft layers. When in use the pack becomes colder (chemical...

    Toronto asked to keep e-bikes off sidewalks and bike lanes!

    I got your point.. but wait?!? What about lycra-carbon cyclist runners who travel at nearly 45 kph (and more) on the cycle lane or on the road? They don’t have any power assisted hub and they go above the theorical speed limits. And what happen if they hit someone or something...

    Toronto asked to keep e-bikes off sidewalks and bike lanes!

    :!: Speed limit should be respected by the “ebikist”, not technologically restricted. Courtesy, respect of security and common sense is needed when cycling on a crowded bike lane. Ebikist and other cyclists have the duty to respect each other’s for their own safety. On an...

    Interface between LiFePO4 and Ezee controller

    **UPDATE** Hi folks, ‘Have plugged the LiFePO4 48V 20Ah on the Ezee kit (front hub + Ezee controller). Everything seems to work well for at least 1 month, and then I ride the bike under rain… To protect the controller I placed a waterproof hood on top of the Ezee controller; bad...

    Interface between LiFePO4 and Ezee controller

    Update. I got an interface plug with 1 XLR at one end and 1 Anderson at the other end. I connected the XLR on the battery, and after I connected the Anderson to the controller's... but when the 2 Andersons make contact, it just spark with a flash of light.. and the 2 connectors got welded...

    Interface between LiFePO4 and Ezee controller

    Thanks YPedal.. But I wonder.. My LiFePO4 pack have a single wire with 3-pin connector. The same wire is used for charging and discharging the pack. From your reply, you seems to refer to a different wire for charging than discharging using Anderson.. Do you mean I can't use a single wired...

    Interface between LiFePO4 and Ezee controller

    LiFePO4 have cylindrical cells packed together. Here's what I'll do: 1) Replace the 3-pin connector from battery pack with a Anderson connector; 2) Replace the 3-pin connector from "XLR to 3-pin" cable with Anderson to get a "XLR to Anderson" setup; This way, I'll be able to connect the...

    Interface between LiFePO4 and Ezee controller

    I bought directly from M. Xie's Company. 2 LiFePO4 58.4v/6A chargers + 2 LiFePO4 48v/20Ah + taxes + air shipping + customs = 1650.00$ CAD (~1200.00$ USD). Straight from Hong Kong. Each 48v/20Ah LiFePO4 cost me 502.00$ USD. Each charger at 29.00$ USD. All new. Both LiFePO4 have a BMS. I...

    Need advice on mixing chemistries

    Thanks dogman, this is very interesting. From what I see, my Ezee geared hub doesn’t heat at all after a 1 hour full speed ride using 48v/8Ah NiCad, BUT the controller and the battery pack did: becomes very hot. This winter, I had a controller shutdown after a climb in snow due to...

    Need advice on mixing chemistries

    Burning the hub huh? That sound bad. But if I use only 1 20Ah pack, then switch to the other pack if needed, do you think Ezee motor should work witht he 20Ah?

    Need advice on mixing chemistries

    Thanks folks, I purchased 2 new battery packs, 48V/20Ah LiFePO4. Probably I won't use NiCAD anymore, depending on the performance of LiFePO4. Any experience with LiFePO4? To swbluto: I work with object recognition, data compression, and several image descriptors for scientific purposes. I own...

    Need advice on mixing chemistries

    Hi, I have a front hub Ezee kit with a 48V NiCad pack. I need to extend the range of my eBike 3x from what I have now. I’m a neophyte with battery pack but I’m willing to learn. I need 1) advices on which battery pack I can connect with my NiCad using a schottky diode parallel "Y"...

    eZee motor + fork with a through axle ?

    Ok, first update. Instead of drawing some sketches, I think you can build your own from the following pictures. The first sleeve is the C-shaped one used to be on the side of your wires. Make this one longer so it should protect your wires if you fall. Locking bolt prevent the sleeve...

    eZee motor + fork with a through axle ?

    In fact, I have no photos of each interface separately. But I will try to draw some diagrams for you to be able to do it yourself. I will post the schems soon.. Some details on the adaptation of a hub motor on a suspension fork: 1. You need to change your springs for the sturdiest since the...

    eZee motor + fork with a through axle ?

    I think drilling through Ezee axle could weak its structural integrity. The wired axle’s interface is a “C” sleeve (allowing the sleeve to setup around wires without having to cut connections); maybe I can work something around the “C” shape, like inserting a...

    eZee motor + fork with a through axle ?

    Hi Almasi, Actually, I have to patch the tire. If the tire is done, then I must unscrew everything and build it back in place after tire replacement. The real problem is if the front tire can't be patched and I'm on the road, then I have a big problem :shock:

    eZee motor + fork with a through axle ?

    Actually, I ride this setting each day this winter on a distance of 30km (going at work), in the snow. I'm 275 pounds and my tires are inflated to only 5 psi for better traction and bump controls. The Ezee is powered by a 48v NiCad battery pack. On weekend, I pull my 2 daughters with a...

    eZee motor + fork with a through axle ?

    Hi rguy56, First I used a bolt, and then I put the machined sleeve on the hub original axle. The bolt is then used to lock the sleeve. If you look at the photo, notice the bolt at the base of the hub axle. The sleeve has a small hole drilled in it and a small flat allen bolt is...

    eZee motor + fork with a through axle ?

    Hi Recumbent, Tires are from Surly, more precisely Surly Large Marge rims (in front a standard Large Marge and rear with Pugsley Large Marge), and I use Endomorph 3.7'' tires. This setup is perfect for snow 'cause it let you "float" above iced rot and it let you ride on top of snow. It give...
