BMS 16s LiPo/LiIon - 50A (symetryczny)

Battery management system (BMS) - it is a device that automates the entire process of using batteries. After connecting a suitable charger to the BMS, it monitors its proper charging and discharging. It is an integral part of a properly constructed 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 and discharged below 3V per cell. In order to supervise them in everyday use, a device called BMS was invented.


Technical data:

Application: Battery16s, LiPo/LiIon
Maksymalny prąd ciągły rozładowania: 50A
Maximum continuous discharge current: 25A
Maximum charging current: above4.22V, ending 4.16V
Minimum voltage per section: 2.65V
Balancing current: 30mA
Dimensions: 95x90x12mm

Cabling is included with the BMS.

Connection description:

B- Connect the MINUS from the battery to this field

C- Connect the MINUS from the charger and MINUS from the controller to this field

Balancing Connector:

BC0- (from the right) is the first cell from the battery MINUS

BC1 (from the right) is the first PLUS cell and the second MINUS


BC5 (right) is the 5th PLUS cell and the 6th MINUS


BC9- ninth PLUS cell


BXX- (Last marking with the largest number) - Last battery cell (i.e. FIRST from plus)

Notes and Tips:

For proper operation, BMS requires an appropriate charger compatible with the battery operating voltage.

We recommend BMS assembly by people familiar with the subject of electronics / power. We suggest checking the correctness of connections 3x before the final start-up.

In an installation with a BMS, overcurrent circuit breakers, fuses and soft starters are not used. The BMS is not disconnected from the battery, it remains connected all the time.

The most common problems when connecting a BMS are confused and incorrectly soldered connectors to the cells: always check the connections 5x before connecting everything to the BMS. Draw everything on a piece of paper. Use a meter / multimeter. If in doubt, contact our technical department and study the connection diagram and descriptions available on the web.

The correct sequence of connecting the BMS:

1. Connect the battery cable (MINUS) to the appropriate field in the BMS -B

2. Connect the cable from the controller (MINUS) to the appropriate -C field

3. Connect the cable from the charger (MINUS) to the appropriate -C field

4. Connect the PLUS wires of the controller, battery and charger (it may spark slightly - this is normal)

5. Finally, connect the balancer cables to the balancer connector (make sure they are soldered in the correct order)

6. After completing the assembly, connect the charger for a while to activate and unlock the BMS at its first start-up.

You should avoid assembling the BMS cables in a different order, it may end up damaging them.

Obsługa na 5, tylko jeden z kompletów dystansów miał zadziory na końcach, które trzeba było zeszlifować. Po tym zabiegu pasują dobrze
Zamówienie zgodne z opisem, dobra jakość, szybka realizacja, mam ewentualną sugestię, aby były możliwe też rękawy o większych rozmiarach do jeszcze większych projektów
