This is a custom extended battery, which can be installed into the scooter instead of the original battery. This is useful if your original battery is exhausted after a few years of usage, or if you just want to improve your scooter characteristics.

This battery grants about 250% of extra range for Xiaomi M187, Essential: for example if your current range is 10 km, it will become about 35 km.

This battery grants about 140% of extra range for Xiaomi M365, 1S, Mi3: for example if your current range is 15 km, it will become about 35 km.

This battery does not affect the scooter top speed.

The battery is assembled of high quality branded 21700 cells, we normally use Samsug 50E, Samsung 48G, LG M50LT. The configuration is 10s4p.

The extended battery is bigger than the original battery, so a special extended cover is needed, or you can use the original cover with a 3d-printed spacer.
