Hey guys,
So i have been driving my first build for a few weeks now with no problems so far, but when I started riding this morning I noticed that the board was super weak, like if it had no battery left, but I had charged it to 98% last night. First thing I did was check the battery indicator which now said 45%, so it somehow lost half its charge, even though I was just lightly cruising on flat ground. Shortly after it barely helped at all and I started kicking. When i came back home I checked the Battery voltage in the bldc tool and it says 30.2 Volts. I have a 8S1P 8000mAh battery. When I plugged in my SkyRc e8 charger, it does not even want to charge my batteries anymore, no matter how often I replug it. I thought maybe the batteries are too low, so I went outside and did some regenerative breaking, which to my surprise brought up the battery indicator from 45% to 75% in about 2 minutes – Isn’t that odd?! But even then, the charger won’t charge my batteries anymore.
Is this a really bad voltage sag? What can I do to troubleshoot? I don’t have a voltage meter but I could get one from a store if needed.
Thanks guys!
