Large external battery from Ewheel with extra high range, the battery is made with 18650 cells. The battery can be installed on Xiaomi, Cecotec, or similar electric scooters and fits into our 2L and 3L bags. The battery supports parallel connection and the use of a switch.
The battery has a capacity of 10.4 Ah and a voltage of 42V.
18650 cells Discharge connector: XT 60 (male connector) -Charging connector: DC 8 mm (female connector) (Xiaomi-type).
Maximum charging: 42v (4.2v per cell): This is the maximum voltage allowed by the BMS when the battery is charged. The BMS will stop charging when this voltage is reached to protect the battery from overcharging.
Balance start: 4v: This is the voltage at which the BMS starts balancing the cells in the battery to ensure they have the same charge. This is important because unbalanced cells can cause damage to the battery.
Cut-off voltage: 30v (3v per cell): This is the voltage at which the BMS stops discharging the battery to protect it from over-discharging. If the voltage falls below this level, the BMS will cut off the power to prevent damage to the battery.
Maximum discharge (current spikes): 30A: This is the maximum current that the BMS allows to flow through the battery in short bursts when needed. It is important to stay within this limit to protect the battery from damage.
Recommended discharge (continuous discharge): 20A: This is the recommended current that the BMS allows to flow through the battery for a longer period. Staying within this limit will protect the battery and extend its life.
BMS with separate charging port: This means that charging the battery and using the scooter can happen separately. It is a convenient feature because you can charge the battery while using the scooter and vice versa.
Maximum charging: 4A: This is the maximum current that the BMS allows to be delivered to the battery during charging. It is important to stay within this limit to protect the battery from overcharging.
Increased range: The external battery significantly increases the range by 20-40 km. You can take much longer trips and enjoy many more experiences on your electric scooter without running out of battery. Compatibility: The external battery can be used on all Xiaomi models. High quality: The battery is reliable, safe, and has a long lifespan. The battery also has a built-in BMS that protects against overcharging, short circuit, and overheating. Therefore, this battery is completely safe to use.
