Can anyone tell me the difference between these BMS, first one says no balance, but lists cell max & min voltages etc, seems to do all it should?

This one is balancing

Cannot work out the purpose of the first unless it uses shunts to bypass individual cells once they reach max safe volts, allowing others to catch up. Found on here affordable pouch cell to cure my problem, so more of academic interest. On Aliexpress I have not found a better deal on motors than BMSB inc shipping but worth looking at for cells
