This is one of my bikes. Nothing special
Regular battery had ~10Ah but bike was bought in store without due to factory defect very cheap.
Motor 250W/24V 8FUN + PAS. Speed up to 25km/h.
After changed power supply now have 34,2Ah (84 cells LG 2850mAh/each capacity - config 7S12P). I upped the carrier throw distance bolt.
Cells are mounted vertically in holders very tightly, together with BMS. Discharge current are very low, because of amount of cells under 1A per cell.
On a one charge I can do distance up to 110-120km (not fully discharge) on full power mode. On eco mode ~180-210km.
