Hallo. I have a problem with installing and connecting a BMS in my 72V Ebike with 24pcs. Headways cells type 40160. I spend already 2 pcs. of the capacitor type http://www.evassemble.com/index.php?main_page=product_info&cPath=6&products_id=46 The 1st one was fried because of misconnection and...

Good day to all. I requested Ecitypower for a wiring diagram for use of their BMS type 3-24S (50A-100A), because it was not possible to download it from their website. After they requested me for a photo, they send me the wiring diagram. A few days later and much to my surprise, a person named...

Were's that video from LPF and what does it mean "... you don't want the cell drying out." Thanks

Thanks for your replies. Those "nifty little pliers" are a good idea. So far I am a bit assured as Scoot did not note any los af performance. Does anyone know a picture, photo or exploded view of the construction of the inside of a Headway cell ? That will make it more understandable of what...

Hallo to all. When I was firmly (I think too firmly) screwing 40160 Headway cells to each other head to tail (I used threaded M6 bars), it appeared that at the end, when the negative terminal became fixed to the positive terminal of the other cell, it was still possible to rotate the cell body...

I want to built a 72V16Ah Lifepo4 24S battery pack and want to use it with a 40A ebike.ca controller on my EV. I now have to make a choice between cylindrical or prismatic cells with soft, or with hard shell. So far I have seen that price, weight and compactness is a little in the disadvantage...

I don't know what cells they have replaced. I will not open up the pack again until the BMS cuts off at 7Ah. (It now cuts off at 11Ah.) 7Ah is what I need for my single home-work ride. Each single cell is 16Ah. (see photo)

I don't know. Here's a photo. Rgds

I want to close out this with a recap of what happened in the past year: I came into contact with Ecitypower (Jack Du) and send my battery back to him in October 2009 for a warranty repair. Their diagnostics revealed failing cells, also as a result of transport damage they stated. They replaced...

Thanks all for your replies. I did already do the test and I have attached the results in a photo. Pay attention to cell 14. I also have attached a photo of the dismantled batterij and the Trice it is used for for your info. Results are already mailed to Ecity power and I am waiting for their...

Hallo everyone, I am new to this forum as a writer, but as a reader I am a frequent visitor. Thanks for all the information and pleasure that I have had when visiting it. The reason for starting this topic is that my 48V16Ah. battery (16 x cell EP1181245, Vcharge=3.65V, Vcut off.=2,4V...
