I'm sorry, but I am not familiar with a BSM Tennis Bat Pro-T20. This is because tennis is typically played with a racket, not a bat, and the T20 format is a type of cricket game, not tennis.
There are tennis rackets that are designed for players of different skill levels, playing styles, and preferences. The right tennis racket for you depends on your playing level, playing style, and physical characteristics. Some features that can vary between tennis rackets include head size, weight, balance, stiffness, grip size, string pattern, and materials used.
