Buy the scooter and this came with a lead acid battery.
The batteries were old. They were in bad shape. They broke down after 15 days of use. I changed the battery for other peers. exposition of a scooter. They were also bad. They broke down in 12 days. I have changed to lithium battery.
By switching to lithium battery. The battery weight 35kg to 20kg step. The useful capacity of the battery multiplied by 4.
By switching to lithium battery modify the scooter.
Active regenerative braking. If braking with the mechanical brake. The controller detects and regenerates a part.
Modify the controller for more power. Change the maximum amperage of 30A to 45A. Adding tin in the shunt. For the scooter up the slopes faster.
Add back topcase.
Conclution:
With lead batteries consumption was 44Wh / km.
With lithium batteries consumption is 35wh / km.
That is 25% more consumption if lead acid batteries are used.
The scooter weighs less.
Higher speed up slopes. Same maximum speed on the flat.
100km autonomy in winter.
