    taking one or two cells out of a pack

    Actually I posted a picture of the cell in another post but no one recognized it because I didn`t get any replies from anyone familiar with it .I will put up the photos again here. Thanks so much for your consideration.

    taking one or two cells out of a pack

    Thanks again for a very informative reply Neptronics, I may have to just give up on this, much as I hate to. I found the name of the original manufacterer in china printed on the bad cell. I did try to contact them twice to see if I could get just one cell and also asked for the name of one of...

    taking one or two cells out of a pack

    Thanks heathyoung,of course that makes sense .So I`am back to trying to figure out how to replace the bad cell. Could someone tell me what I need to look for when trying to match a new cell to a battery pack.

    taking one or two cells out of a pack

    I have a li-mn 36v 10ah battery that consists of 10 cells . One of the cells is bad but I can`t find a replacement. Would my bms be ok if I just soldered 8 cells together? thanks

    need li-mn 36v cell

    thanks floatingdog in answer to your question when fully charged it records 42-43 volts.You mentioned something interesting, I would be happy to use this battery as a back-up battery with just 9 cells.I just didn`t know that I could do that.I wonder if my bms will be happy with that?

    need li-mn 36v cell

    After 38 views I have not heard from anyone who knows where I could find this cell. I guess I will have to take a different approach. Could anyone tell me wow I could find (or build) any 36v 10ah cell that would work with the other 9 cells in the battery pack. I would sure hate to throw it all...

    need li-mn 36v cell

    I just recieved a new battery from Ping and am very happy. I thought now I would try to repair my old limn battery and need to replace a cell. The battery consisted of 10 cells and I found the name of the original manufacterer in china printed on them. I tried to contact them twice to see if I...

    test for faulty bms

    Thanks for the response dnmun, sorry I didn`t get back sooner but I was out of town for the weekend. All of a sudden my battery isn`t cutting out any more.One of three things I did corrected the problem but I don`t know which one it was. I took off what I considered to be the bad cell and then...

    test for faulty bms

    I have done some searching but can not find out how one would test to see if a bms is faulty. If someone could direct me to someplace where I can read about this or just tell me what the proceedure is I would very much appreciate it . thanks 350 watt 36v 10ah li-mn

    intermittently cutting out

    I`m real new to this but If I bypass the bms what would cause the battery to cut out at all ? Doesn`t the bms control the lvc level ? meaning No bms = no lvc = no cutting out ? Please tell me what I am missing here. thanks

    intermittently cutting out

    Sorry dogman I didn`t make myself clear.when fully charged the cells are 41 all accross.After I ride the bike for ten minutes it cuts out, When I turn the switch off and back on it starts again but only lasts about 15 seconds before cutting out again. Whe I went to test the individual cells I...

    intermittently cutting out

    So true dnmun and I really appreciate all the help I recieve here from you and the others. I have quite enjoyed learning the bit I know and look forward to learning more. I don`t know if you have read my post about the volt readings on my idividual cells but I have a cell that shuts the battery...

    intermittently cutting out

    Oh yea it`s wonderfull to buy here so that you can count on being gouged to death by your North American dealer if something goes wrong. One of the reasons I didn`t just take my bike back to the original dealer is because I am scaired to death about what they would charge me. I needed a charger...

    intermittently cutting out

    I hooked up my battery to my bike with the back wheel off the ground. I couldn`t really put it under load this way but I ran it for an hour and a half before it cut out I turned it on again and measured my cells, eight of them were 33-34 volts, one was 32 volts and one was 27 volts. I don`t know...

    intermittently cutting out

    I have 10 cells and I measured each one by putting the multimeter probes on the pos and neg posts of each one. I got 3.6 per cell and I did it 3 times with the same results. even reversed the multimeter probes and got -3.6 all the way. It appears that the cells are an even 3.6 accross the board...

    intermittently cutting out

    thanks dnmun but I`m really dense with this stuff and am scared of a shorting something so I have to ask.If I put the red (positive probe on the blue weld where would I put the black probe ?. :oops: As far as the type of cells ..I am only going by what they told me at the shop where it was...

    intermittently cutting out

    Actually I got thinking and reasoned that if I`m going to get a new battery anyway I may as well experiment a little on this one and it also occured to me that if I`m too chicken to try I`ll never get to know this stuff. Which would be dumb because I really do enjoy ebikes. I was wondering if...

    intermittently cutting out

    Thanks jonathanm that was a great suggestion, I spliced into the wires and using my multimeter I was able to watch the voltage under load. I started with 37 volts, It cut out 3 times, and I reset it each time . It dropped to 27v the first time it cut out after 5 mins, the second time after just...

    intermittently cutting out

    Just prior to ordering a new battery I have one more question. I did another test run and as expected after going uphill for a few moments It cut out. This time I did a test without turning it off and back on (reseting it), I just pulled the power connector off and tested the battery prongs with...
