Frequently Asked Questions (FAQ)
Is this battery guaranteed to fit my Xiaomi Electric Scooter 4?
Yes, this battery with model number T2201-BA3A and a capacity of 7650mAh is the original battery for the Xiaomi Electric Scooter 4. It ensures full compatibility and restores the range specified by the manufacturer.
Can I replace the battery myself?
Replacement is possible for individuals with basic technical knowledge. Several screws on the scooter's bottom plate must be loosened to access the battery compartment. The old battery then needs to be disconnected from the electronics, and the new one connected. It is recommended to watch a video tutorial beforehand.
How far can I go with this new battery?
With a fully charged, new battery, the Xiaomi Electric Scooter 4 can achieve a maximum range of up to 35 kilometers. However, the actual range depends on factors such as rider weight, riding style, tire pressure, temperature, and terrain profile.
What does the 'Intelligent Battery Management System' (BMS) mean?
The BMS is an electronic circuit that protects the battery and optimizes its performance. It prevents critical conditions such as overcharging, deep discharge, overheating, or short circuits. This ensures safe operation and the longest possible lifespan for the battery cells.
Why does the title say 21.6V, but the scooter is a 36V model?
The nominal voltage of the entire battery pack that powers the scooter is 36V. The 21.6V specification is technically unusual for the overall system and could refer to an internal series connection of cell blocks. The crucial factors for compatibility are the 36V system voltage and the maximum charging voltage of 42V.
What is the best way to store the battery if I don't use the scooter for an extended period?
If you don't use the scooter for more than 30 days, charge the battery to approximately 80% and store it in a cool, dry place (ideally between -20°C and 45°C). To prevent deep discharge, the battery should be recharged every 1-2 months.
