Hello, I have a speedway smartgyro with 2 batteries in parallel. Both batteries are twins, the same, same cells, same bms.
With both batteries in parallel, the scooter travels 45 km in total. They are 48v 13s5p batteries with 2500mah Sanyo cells.
Do you know why it has so little autonomy? I checked to see if the cells were balanced (I have an active balancer but I have not connected it) and they were all at 4.17 with the scooter loaded. At 54v.
All the best.
