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 working during ...

Re: 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 reaction?)...

Re: 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? What’s ...

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 pack usin...

Re: 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 battery pack...

Re: 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 don't have wr...

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 controller ...

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?

Ok, first update. Instead of drawing some sketches, I think you can build your own from the following pictures. http://bayimg.com/image/lanfjaabl.jpg 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. http://ba...

Re: 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 “lo...

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:

Re: 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. http://www.vmqca.qc.ca/chroniquesdegilles/2008/11/20081126/photo10.jpg http://www.vmqca.qc.ca/...

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.
