So, I just got my new charger in the mail today and I decided to test the scooter. No success but the battery keeps flashing red? There's a small led on the battery that just keeps flashing like once every second or so in red..?

if I remember correctly the red flashes when its flat otherwise there should be a blue light flashing. I couldn't get any of my battery's to charge with the ebay charger I got :/ it charges for like a sec then the light on the charger goes green again and this just repeats

Shows 8v when measuring it? Perhaps it's too low.
Edit: Just checked the control board, zero output on the battery port when plugging in the power...I'm guessing the control board is toast.

unscrew 4 screw's in corners [it's glued with silicone] and you get access to BMS with LED and RST button , but red flash is signaling some fault, try to check voltage of battery segments or each one

Hi. I have an ES1 and the same problem. It won't turn on, even if plugged in. Disassembled it. The battery led flashes 6 times when power is connected. Otherwise nothing. When measuring battery power level, it shows 8.5V. I'm not sure if it is the battery itself or the control board. I'll try to find screws and a reset button.
Cheers,

Internal battery ES1/ES2 flashing red

Ok, now I'm really puzzled...
My ES1 won't turn on.
Whenever I connect the power supply (or the 4-pin plug of the battery), the battery led will flash 6 times. No blue indicator.
I replaced the fuse on my old mainboard. Nothing. I figured, the mainboard might be roasted - because if the power supply is connected I thought it should turn on, regardless if a battery is connected or not. So I ordered a new control board (plus Bluetooth/Cockpit).
But it is still the same. The only original component is the battery. So I guess it is gone. I already unscrewed the top and pressed the reset button. No difference. I won't dare to open the battery itself (since that is probably risky).
Any recommendations? Or any idea where I could get a new internal battery (NEB1002-H) in Germany?
Thanks!
