The set includes:
PACKAGE 10S 7P
Lithium-ion pack. It is the main element for the construction of the battery. After soldering the matching BMS, it is ready to work.
CHARGER 10S 3A 54,6V DC 2.1/5.5
Fast automatic charger for LiIon and LiPoly batteries (lithium-ion and lithium polymer). No configuration required, works immediately. After the battery is charged, the charger switches to standby mode.
CASE
The case is spacious enough to allow the use of all 70 cell baskets, and it can also fit a BMS inside.
BMS
Battery management system (BMS) - it is a device that automates the entire process of using batteries. After connecting the appropriate charger to the BMS, it supervises its proper charging and discharging. It is an integral part of a properly built electric bike.
Lithium batteries (lithium ion, lithium polymer and others) are serviceable and require care and attention. They cannot be charged above 4.2V per cell or discharged below 3V per cell. To monitor them in everyday use, a device called BMS was invented.

Attention:
Do not connect this battery model to the set MTB Mxus 3K Turbo 3000W.
You don't know if the 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 round. 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 (discharge 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 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.
