Self-assembly battery for rear rack 48V 24,5Ah

A product for beginner users.

The package has marked fields for BMS mounting, which will make it very easy to finish the battery construction and have video instructions. The kit also includes all the necessary components for assembly (wires, tapes, etc.)

Universal silicone to immobilize the package and seal the housing

You do not know if the battery case will fit into your bicycle frame? Download the templates and print it in a 1:1 scale, after printing, check that both marked dimensions of 50mm are consistent with reality, otherwise the housing could be printed in a different scale and the dimensions will not match.

The battery is compatible with the following sets:

City kit XP03 Mxus XF15
Trekking kit XP04 Mxus 30H

Note: Do not connect this battery model to the Mxus 3K Turbo 3000W MTB set.

Advantages of assembling the battery yourself:

You save up to PLN 400
1. You save up to PLN 400 on the cost of the battery. The assembly is easy, no specialist knowledge is required, we attach simple and convenient "Step by step" instructions. An ordinary soldering iron is enough for assembly (we recommend the cheapest soldering station for about PLN 100). We estimate the duration of the assembly at about 1 hour for an inexperienced user. Our service department is there to help and know if you run into any problems.
You gain unique knowledge
2. You gain new, unique knowledge. You know what you buy. You learn how the battery works and how it is built, so you know how to care for it better, and it will repay you with a longer failure-free operation.
You save in the future
3. If you are going to build another electric bike for your family or friends or you will be willing to buy a second battery to increase the range - the ability to build yourself will result in further, even greater savings and another portion of interesting knowledge in the new hobby of electric bikes.

The kit includes:



CHARGER 13S 3A 54,6V DC 2.1/5.5

Be sure to connect the charger to the batteries in the correct order. ALWAYS connect the charger to a 230V socket first and then to the charging socket. DO NOT connect upside down. This can quickly damage both the charger and the BMS installed in your battery. Reverse connection causes the effect of sudden charging of the output capacitors of the charger through the BMS socket. This is accompanied by the flow of huge current that can damage the plug, socket, BMS mosfets or even the charger transistors.

The real capacity of a package (available capacity) is always lower than the nominal capacity of a package (rated capacity of its cells). It is assumed that a ready battery based on a package will have about 10% lower real capacity than the theoretical rated capacity. It is caused by many factors, such as the decrease in the capacity of the cells under load, or leaving the unused capacity by the BMS (discharge to the minimum cell voltage to about 2.7V) in order to extend the life of the battery.

If your BMS has a turn-on circuit (two white wires) and it is disconnected (wires are not short-circuited) then it needs to be connected (short-circuited) to turn on the BMS.
