BATTERY FOR ELECTRIC BIKE 13S5P 48V KIRIN
An efficient lithium-ion battery built in a 13s5p configuration with a nominal voltage of 48V, based on modern cells that provide high power and stable performance. It is perfectly suited for electric bikes requiring a solid and reliable energy source, both for daily commuting and for longer recreational rides.
The battery’s design has been developed with durability and safety in mind. The integrated BMS system protects the battery from overcharging, deep discharge, and overheating, which extends its lifespan and ensures trouble-free operation. It is an excellent solution for users looking for a combination of high capacity, reliability, and long range in one product.

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 at a scale of 1:1, after printing, check whether both marked dimensions of 50mm 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 the 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. 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 actual capacity of the package (available capacity) is always smaller than the rated capacity of the package (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 shorted), it must be connected (short-circuited the wires) to turn on the BMS.
Each battery 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
- BMS damage
- Capacity decline (over 15% per year)
The warranty does not cover:
- Errors in assembly that do not comply with the instructions or workmanship
- Improper maintenance
- Mechanical damage (cracked/broken casing, melted connection terminals, etc.)
- 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 power for the first 10-15 minutes of riding.
4. Do not charge the battery with a current higher than 3A.
Opinions about E-bike battery Kirin - 48V 13s7p (13-17,5Ah)
5/5Opinion not confirmed by purchaseGreat kit, very fast delivery, battery pack already professionally prepared, I have the version with EVE INR18650-35V 17.5Ah, great video, understandable even without understanding Polish, I installed the BMS SP14S004 with Bluetooth instead of the supplied BMS ZP13S001, so that I can monitor the battery via APP.
