If you want the exact model, you should ask the battery seller for the BMS. Otherwise, it is almost impossible to buy the same model. You will have to buy an equivalent BMS and reconnect all the wires, unless you are lucjky and they use the same balance connector with the same wire order, but they never do.

Look on aliexpress for a 13S BMS, 20A, on/off. I would get one with balance function too, Check the specs to make sure the balance data is in the chart. Sometimes they say balance, and leave the balance specifications blank, meaning there is no balance,

I am using a 48V 20A BMS from the Annpower seller on aliexpress. It works well.

thx for reply.
I tried it. but annpower have not bms with required size.

The JBD labs is the required size, but they sent me one that didn't shut off properly and then sent me one that blew up. I don't recommend them at all.

All you can do is keep looking.

We are using 13S 48V 20A BMS with on/off switch for battery with key controlling the battery output, or a switch button controlling the output.
The BMS is designed by Super Power, best ebike battery BMS manufacuter in China.
Model no. SP-R13-068-A02-M13SY
Dimension:60*32*15mm
Without balancing function (For Samsung or Panasonice cells come with good consistency , the balancing BMS is not necessary.)
The BMS spec data sheet is attached for info.

Balance wire sequence seems different.
