Here you go.

If anyone happens to be in the Cleveland (or Detroit) area...I have 4 of the Ego 56V 2AH batteries that I'd like to turn into a battery for my scooter. Unfortunately I don't have the electronics knowledge to do so myself. But if anyone in the area is interested, I'd be happy to compensate you...

Ok I soldered the sense wires back in the new order (leaving the number 15 sense wire free), and attached a 12 gauge wire between cells 6 and the old number 8. I also have it in compression. It looks like the weakest cell is the old number 11, the puffy one, it measures 3.0 V. Should I...

Ok, I had the pack in compression for 5 days, unfortunately it didn't really change much in size. I cut out that dead cell #7 flush with the top of the cell, like you mentioned. I also cut off the sense wires from cells 8-15. I'm confused now on how to reattach the sense wires. I feel like I...

Thanks for all of your help. I think I'll give a go at rewiring it to 13 cells. I'll let you know the results when I'm done!

Ahh, the confusion was my doing. That 3.656 I measured was off of cell number 1, which I didn't include in my initial list. I only measured 14 cells initially, but now I've measured all 15. Cell number 7 has always been dead. Is this the right replacement to buy? This was one of the only...

I guess I'm a little confused....I was assuming that I can't get a reading because that cell is dead. Even when I try and measure the voltage at the cell (where the blue and purple wires are soldered to the strips of metal) I still don't get a reading. I can't check the voltage at the BMS...

I took apart the battery a little more. I measured that cell I was missing...it's at 3.656. The pen is touching cell number 7, the one that's dead. It's between the blue and purple wires, neither of which look loose. Is that what you meant by sense wire? Cell 11 is the only one that looks...

The entire battery is dead, or just the one cell?

Yes I have the same charger that Milou described. I'll take apart the battery further to try and expose the sense wires. Does it have to stay in compression the entire time that I'm trying to take it apart and examine it? And what's the best way to compress it...duct tape or something similar?

Yes I'll take it apart as soon as I get home from work. Unfortunately I'm not sure of the chemistry. Regarding the BMS...it's completely sealed and can't be opened. The battery and BMS are identical to the one Milou describes in this thread...

Alright I just checked individual voltages between each of the 15 pins: 0-1 3.656 1-2 3.351 2-3 3.719 3-4 3.469 4-5 3.431 5-6 3.349 6-7 14mV 7-8 3.319 8-9 3.556 9-10 3.698 10-11 3.135 11-12 3.454 12-13 3.705 13-14 3.356 14-15 3.428 I think I somehow didn't measure a cell...since I only ended...

Here's a video I just shot: https://www.youtube.com/watch?v=yatFOoS2cq4 Everything died before I was able to run the throttle. Sometimes the throttle does actually work, but the wheel turns really slowly. I'll try and catch it on another video. Again, the dashboard lights up like this only...

Ok I'll check the continuity. One other thought: When I have the charger plugged in and the ignition turned on, the DC/DC converter makes a ticking noise. Is that normal? Even if the DC/DC converter is broken, would that cause the motor to lose power as well, or just the lights, etc? Edit: It...

Just to clarify, the problem isn't just the motor not turning, I don't get any power at all...(no headlights, dashboard lights, etc). The picture I posted with the headlights on is something that just happens spontaneously when I leave the charger plugged in. Everything then shuts down after a...
