Do not buy - extremely low quality battery packs
Do not buy - extremely low quality battery packs
Windgoo uses (or used) battery packs from unknown manufacturer called Shenzhen Longting Technology Co. Ltd. After a few years of very light use, the battery pack failed in our Windgoo M12. I doubt we even put it through 20 cycles. We never let the voltage drop too low. What would happen is the scooter would work for around 5 minutes and then just cut out completely. Since the scooter is essentially ewaste now as either buying a battery pack or replacing every individual cell manuall would cost more than a used M12, I took the battery pack apart to see if I could re-use the cells for something else. First off, the cells are not even matched - some cells have dark writing on them and some have light writing, which suggests the cells have at the very least come with different batches. Secondly, I have only tested 8 cells so far (out of 30). 4 of the cells have tested bad. We had 1 cell test at ~1900mah which is good, as these are advertised as 2000mah cells. 2 more tested around 1700-1800mah, which is bad enough as they are not wearing at the same rate. Another cell tested at 1200mah - horrible. 2 cells tested at 500mah!!! So we have some cells testing at 1900mah and others testing at 500mah. No wonder it was cutting out. The cells are low quality, not matched, meaning the battery packs made by Longting are cutting corners and will fail after not much use. I highly advise you do NOT buy a Windgoo and go for something more reputable.
