48V15A 13S Master & Slave BMS

Model No: ZBH48V20ATCU-XDS.F (Slaves) /  ZBH48V20ATCU-XDS.Z (Master)

Battery packed series: 13S

Battery type: Li-ion Battery Cell

Rating voltage: 48V

Max discharging current: 45A

Max charging current: 25A


1) Safety

     This BMS is dual switch design. When one group of battery is loading, another group should be in shut down mode.

2) Emergency

     Both battery packed have individaul switch. Once a group of battery break down another group should be replaced immdeiatey

3) Durable:

    Two group of battery should be interchange automatically through the BMS controlled. Once the main unit is in low power status, 

      the successive power is provided by another unit

【Series】:Tailor Series


This series concerned signal BMS system controlled dual battery packed. Due to the scooter adopted two battery packed, the running time should be longer than the normal one. Through the dedicated fast charger, it allow the charging time shortly. This BMS widely used in the far distance electric scooter


Application Scope

Electric Scooter/ Electric Tricycle



1) The BMS designed based on 13 series which is the standard of electric scooter standard

2) UART interface can read the battery state and modified the BMS frameware

3) Two battery packed can be interchange the power automatically

4) Temperature sensor monitoring

5) Accurate SOC information

    Coulomb electricity calculation, provide the accurate figure about the battery SOC

6) Support Mosfet failure detection function

7) Fully protection function

     Once the main unit is in low power status, the successive power is provided by another unit
