BATTERY DOWN TUBE 48V 13S4P DP5
A solid lithium-ion battery in a bidon-type case, built in a 13s4p configuration with a nominal voltage of 48V. Thanks to its ergonomic bottle-shaped design, the battery is mounted in the bottle cage position, ensuring an aesthetic and convenient installation on the electric bike. The pack’s capacity provides sufficient range for everyday use, while the integrated BMS system protects against overcharging, deep discharge, and overheating. A practical and safe solution for those who value reliability and a discreet appearance.

Attention
Do not connect this battery model to the Mxus 3K Turbo 3000W MTB kit.
You don't know if the battery case will fit your bike frame? Download the templates and print in a 1:1 scale. After printing, check whether both marked dimensions of 50 mm are consistent with reality, otherwise the casing could have been printed in a different scale and the dimensions will not match..

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 upside down. This may quickly damage both the charger and the BMS installed in your battery. The reverse connection causes the effect of sudden charging of the charger's output capacitors through the BMS socket. This is accompanied by the flow of huge current that can damage the plug, socket, BMS mosfets or even charger transistors.
The real capacity of the pack (available capacity) is always smaller than the rated capacity of the pack (rated capacity of the cells it contains). It is assumed that the finished battery based on the package will have approximately 10% less real capacity than the theoretical rated capacity. This is caused by many factors, such as a decrease in cell capacity under load or the BMS leaving unused capacity (discharging to the minimum cell voltage of approximately 2.7V) in order to extend the battery life.
If your BMS has a turn-on circuit (two white wires) and it is disconnected (the wires are not short-circuited), it must be connected (short-circuit the wires) to turn on the BMS
Where are down tube batteries installed?
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.
