    battery with one cell down => cell or BMS problem ?

    for sure I'll give the reason of the problem here - when and if I find it ;-) Do you think I can invert the BMS wire 8 to another one to see if problems moves to another cells? This will tell if it's the fault of BMS right ? I don't remember if they need to be in specific order or not.

    battery with one cell down => cell or BMS problem ?

    Hello! I have a problem on my ebike: one cells seems not working correctly. It gets quickly discharged to 0v and does not charge to full 4.2V. When the other cells are charging this one charge lower. I have a bluetooth BMS so I can have a good idea of it real time. It can makes my battery...

    electrical question: horn cuts my engine

    Guys, thanks a lot for that brainstorming here concerning this electrical noise from my horn :-) I was currently moving house, new job, so didn't have time to see what was going on here and reply. I will see what I have and make some test, probably try resistor and capacitor if I find correct...

    electrical question: horn cuts my engine

    i can try that, where is it located in a car? I know on alternator you have like a 15vvoltage limiter, but I don't think that's it

    electrical question: horn cuts my engine

    Hey guys! I have a specific question on my bafang 750w. It runs well but I installed this horn: https://fr.aliexpress.com/item/4000218317520.html?spm=a2g0s.9042311.0.0.27426c37MTynRr it's directly connected to the output of battery, with a switch inbetween. It works good except it cuts my...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Yes, the torque sensor of TSDZ2 appeals me, especially that I want to do a bit of workout as riding ;-) but I also wants to go long distance, do like 100Km rides, do you think the TSDZ2 would handle that well without overheating ? I read that bafang is much more powerfull but the TSDZ2 have more...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Hi Guys, I am building my electric mountainbike and really hesitate between an TSDZ2 with cfw or a BBS02. I understand TSDZ2 is maybe a bit less reliable, especially blue gear, and less powerful, but the feeling is better, as the power given by motor is really synchronized with the effort on...

    Building my first ebike - advice needed ;-)

    Hey guys thanks for the answer FarmerFpv I actually decided ordered a full GA pack in 13s6p from tumiche in this forum. Seemed to me the best price/quality option to me, even if I wanted to do the battery myself, seems it will not be the case. I ordered this BMS which has bluetooth, and seems...

    Hey Guys! I'm actually studying to make my first ebike, and decided to register and ask your advice here after reading a lot of topics ;-) the theory is a good first part, but I want to share with you my plans before ordering because the experience is also very interesting and I don't have any...
