    Bike cutting out when battery on 3 bars

    So I want to hold both probes to this bump on the below attached photo to take a reading? Anything specific I can do to be careful? The exposed end of the multimeter probes are about a fingernail long, I could put PVC tape on them to just expose a tiny bit? @Bikes4two the seller said he...

    Bike cutting out when battery on 3 bars

    Thanks! Here they are :) The white bit on the side is what a guy on youtube seemed to test, but it's glued to the rest and I don't want to break anything. Also I have used the bike from fully charged a couple times since and noticed it breaks down once the voltage drops below 44.0V (the voltage...

    Bike cutting out when battery on 3 bars

    Multimeter gave a reading of 52.9 when fully charged. I screwed open the battery case but now it seems that if I open the taping keeping the cells together to test them, it will be very difficult for a novice like myself to put it back together?

    Bike cutting out when battery on 3 bars

    Thanks for the quick response! Both the battery and controller were showing at least 3 of 4 bars before each shutdown though, so I imagine this would indicate the battery was not actually low enough to shut off? It was showing 49.1V without any power and was shutting off when it dropped to 46V...

    Bike cutting out when battery on 3 bars

    I bought this custom made bike 2 days ago https://www.adverts.ie/other-sports-...nches/25432673 Was close to fully charged, worked well day 1. Charged for a few hours and today after about 8km it cut out, just after a stop at a shop. The battery was showing 3 of 4 bars but the voltage started...
