my Koowheel board was send back for repair and they said that the batterij was the issue.
They offered me a 4400mah battery (samsung) in place of the 5500mah (LG). Apparently the LG batterij is not as good as the Samsung one. Quality issue they told me.
I waited for a month for a new battery and but they had none in stock. So i asked for a refund.
So i don't have a board right now.
I am waiting a bit for maybe a revision before i order a new one.
