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...

Hi pwbset, Actually I'm not knowledgeable enought to give you this kind of info, but DocBass should help me out soon with a new ebike setup, using these packs.. maybe he can test them and post the results after. Here's the basic infos about the pack: Normal Voltage:48V; Capacity:20 Ampere...

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...

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...

:!: 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...

**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...

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...

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...

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...

Oh, I forgot.. M. Xie is the owner of Ecity Power.. Check out his website at: http://www.ecitypower.com/index.php?page=1

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...

Ok.. I’m a nearly perfect newbie in electronics and electricity setup and I purchased 2 LiFePO4 packs that I must rewire... DOH!! The good news is that I just receive them today! Straight from Hong Kong! And the other good news is that YOU can help me out with the wires issue. Let me...

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...

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?
