Battery 48V Kirin DK-21700-5 – 16Ah
High-quality battery based on 21700 cells, built in a 13s4p configuration, with a nominal voltage of 48V and a capacity of 16Ah. It provides high energy density and stable operating parameters, making it an ideal power source for electric bikes. With solid construction and a protection system (BMS), the battery ensures safety, long service life, and reliability in everyday use.

Remember to connect the charger to the batteries in the correct order. ALWAYS first connect the charger to a 230V socket and then to the charging socket. DO NOT connect it the other way around. This may quickly damage both the charger and the BMS installed in your battery. Reverse connection causes sudden charging of the charger’s output capacitors through the BMS socket. This is accompanied by a huge current flow that can damage the plug, socket, BMS mosfets, or even charger transistors.
The actual capacity of the pack (usable capacity) is always lower than the nominal capacity of the pack (the nominal capacity of the cells it contains). It is assumed that the finished battery based on the pack will have about 10% less usable capacity than the theoretical nominal capacity. This is due to many factors such as cell capacity drop under load or the BMS leaving unused capacity (discharging to the minimum cell voltage of about 2.7V) to extend battery life.
If your BMS has a power-on circuit (two white wires) and it is disconnected (the wires are not shorted), you need to connect it (short the wires) to turn on the BMS.

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.
