    BBS02 just died, any pointers?

    Hmm so should I worry now about the BMS? Matbe it was a bad sensor? I measured 4.2v from each cell package from the sensor cords going into the bms. Bit I dont want to risk anything here. Maybe the battery will explode or something? :) My guess is that I had a cell that would not charge before...

    BBS02 just died, any pointers?

    It works again! I was able to charge it at work before and measured 54v after charging.(which it hasnt showed before) So maybe if Im lucky the BMS did something and has repaired itself? Maybe some cells that recharged now, that did not recharge before? I have only tried to start it and used...

    BBS02 just died, any pointers?

    Thanks, so if the BMS is tripped, then the battery is not able to fix? It could still be a battery fault then? I will try to figure out how to put the battery on a load while still measuring it. Now the XT60 connection is hardwired to the cords. Im guessing I have to remove that connection to...

    Its 54v with the charger connected. So wouldnt I be able to start the bike then with the charger connected? I´m guessing its not the battery after all?

    BBS02 just died, any pointers?

    I have the charger with me today. When removing that bms Contacts last time the cord to the right got loose, but it could snap in but maybe something got broken when it was loose also? I hope they know how to measure with charger in. I just measure the xt60 contact while its charging? I havent...

    BBS02 just died, any pointers?

    EDIT! NO LUCK WITH THE NEW WIRING :( Nothing at all happend when plugging it into the bike like that. Ah, sweet! So I cannot measure in that BMS instead of trying to dismantle the batteries? Yes, I have had it in the charger yesterday and some whole days in the charger without use. But it has...

    BBS02 just died, any pointers?

    Thanks, my colleague here told me that the battery should give me 48v out and not 40.8v? He told me that maybe some cells in the battery may be dead? And that it is not working because of that? Hovewer, the display should maybe go on even with 40.8v?

    BBS02 just died, any pointers?

    I have just detatched the pins and metal clasps now. I will try to solder the cords together to see if this works. I have today measured again the battery. Giving 41v. I have drilled a hole in the case for the cords as well I noticed this red cord was loose. Is this just to the...

    BBS02 just died, any pointers?

    Also if buying a new battery, will this work? Is the same connection? Can I put them in my yellow one? (Doesnt look so). Maybe some adapter needed? Also Im thinking if its better to install the battery on the opposite side where the water bottle is mounted...

    BBS02 just died, any pointers?

    Thanks, I will take that picture to work tomorrow. However I cannot get the bike to work now :confused: But maybe I can borrow a multimeter and measure myself somehow? Im thinking that its not the display? Because I got it working for about 30s a few days ago. Display looked as ususal. And...

    BBS02 just died, any pointers?

    Hmm, look at this, this does not look that great? Im thinking if I can bypass the pins? If so, do I need to buy something? It did broke even more now when I was trying to get that pin-plastic thing of the battery.

    BBS02 just died, any pointers?

    Got a small glitch from the display when coming home before, a second only. :( This is how it looks while plugged in now when testing. (I have removed the battery now and opened it up to be able to provide pictures on how it looks while the battery cord is mounted in with the pins in the...

    BBS02 just died, any pointers?

    Its not turning on again after the 20s when it works. Somehow maybe that says something about the battery. I will try it again now when its been charging the whole day. Can I put some copper paste or something maybe on the battery where the pins is inserted or maybe sandpaper the pins or...

    BBS02 just died, any pointers?

    This is my guess also, can this be fixed? I can bring it to my work and probably I can ask for help here. They do work with electrics and soldering stuff here. But I dont want to waste their time to much so I want to limit down the possibilities first :) Can I try to put this (see picture)...

    BBS02 just died, any pointers?

    The battery is taken off. Sorry for not being able to sort that out. I did measure the battery at my work. (Not me, but a guy there helped me). He did however not noticed anything wrong with the battery or charger. So I have mounted the battery again on the bike if that was unclear. I do remove...

    BBS02 just died, any pointers?

    I have the very same behaviour now. Yesterday it was a bit cold here, and slippery. So on the way to work I fell with my bike. But it was just a scratch for me, so I biked the way to work. Then after work I went home with the bike. No problem at all. The bike is standing inside during night...
