    PAS not working with brand new controller

    Hm well... pedaling backwards does work! I flipped the magnet ring and now it works alright. That's a bit puzzling though... the PAS did work correctly with the previous controller and the magnet ring mounted the other way around.

    PAS not working with brand new controller

    788 spot welder

    Hi, A quick feedback about that line of spot welders... I bought a 709A a couple weeks ago which must not be very different from the 788. Product worked perfectly for my 18650 pack. I spot welded 0.15mm nickel tabs without a problem, I don't think 0.2mm strips would have been much more...

    Hey Riba, Thanks for the reply, much clearer now. One last thing troubling me... I am wondering whether I made a mistake or not by linking the 4p cells with a "square" nickel strip (picture 1) instead of a "straight" line where I would remove one of the link of the square strip (picture 2). I...

    Advice on homemade pack

    Hi Riba, Thanks a lot for the reply. Why weld nickel strip only on series connection and not parallel connections? I am probably mistaken but I thought that basically there would be about 25A through the whole "square" nickel strip welding the 4p cells together and 12,5A through each of the...

    Question about connector

    Hi all, Can anyone please tell me what type of battery connector is this? It is from a battery case bought from a 3rd party but which definitely comes from bmsbattery from the look of it (https://bmsbattery.com/ebike-parts/560-aluminium-03-battery-case-for-ebike-carrier-parts.html). I need...

    Using lifepo4 charger for li-ion battery

    Thanks a lot for the reply. I would like to keep using the charger for the lifepo4 battery pack as well so I will go with the first option: losing 5% of charge on the li-ion pack!
