To maximize battery life, use the following recommendations:
1. Fully charge the battery after each ride
2. Fully charge the battery every 3-4 weeks when you do not use it, e.g. winter break.
3. In the autumn and winter (temperature below +12*C), lithium-ion batteries have a lower capacity (by max. 30%) than in the summer, which results in a shorter range. This is normal. During this period, do not use the full power for the first 10-15 minutes of riding.
4. Do not charge the battery with a current higher than 3A.
