Welding lithium-ion cells 21700 into a package

Each cell and package in the nexun.pl online store is covered by a 24-month warranty for consumers and a 12-month warranty for companies.

The warranty covers:
- Cell damage
- Capacity decline (over 15% per year)

The warranty does not cover:
- Errors in assembly that do not comply with the manual or workmanship
- Improper maintenance
- Mechanical damage
- Changes in the product's operating characteristics depending on weather conditions (temperature)
- Water damage

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 powerf or the first 10-15 minutes of riding.
