This one worths a look.
Over volt
Under volt
Balance triggering volt
All adjustable 2.40V----4.40V
Balance method (2-3A): dumping / transferring .
WiFi monitor and remote control. Fuel gauge .
Product basic parameters
1. Integrated management system for lithium battery, BMS03B can monitor 3-8 lithium iron phosphate ternary and polymer, BMS03C can monitor 10-16 lithium iron phosphate 10-14 ternary and polymer, BMS02X can monitor 3-5 12V single cell 36-60V lead-acid battery pack (BMS02X only balanced without overvoltage and undervoltage protection)
2. Use the MODE button to switch parameters, and + and-to add or subtract parameters. 3. Single-cell voltage monitoring and management of the battery pack (overcharge and overdischarge voltage values can be set by themselves).
3. Two equalization modes: active energy transfer + passive resistance energy consumption, intelligent balancing and forced real-time energy transfer balancing
4. The monomer overvoltage monomer overvoltage range 2.40V-4.40V can be set freely
5. Support free setting of balanced starting voltage 2.40V-4.40V, and free adjustment of balancing precision pressure difference interval 6mv-108mv (color screen version)
6. With temperature protection function, collect the temperature of the whole machine and the equalization module to reach the over-temperature value, pause equalization and over-temperature, stop charging and discharging, and shut down the protection function
7. With a complete power off function to protect the battery safety.
8. Relay protection board (high and low voltage shutdown is to control the relay coil relay to control the overall positive on and off of the battery pack to achieve undervoltage and overvoltage protection) When the undervoltage protection is detected, the charging access automatically opens the relay to charge the battery pack, overvoltage After the protection, the return value of the overvoltage protection is automatically turned on by the monomer fall or the trigger relay discharge is triggered manually
9. The voltage display accuracy is 0.01V, and the charging and discharging parameters are set by the user.
10. Active energy transfer balanced current 2-3A peak 4A
11. Rich parameter display, battery pack voltage, total voltage, battery pack real-time charging and discharging power, current and capacity display
12. The full-platform Internet of Things remote monitoring supports Android/IOS smart phone tablets and various computers
13. Over-current and short-circuit protection methods: fuse blowing type and open circuit combination
14. The charging voltage of 3-8 strings does not exceed 30V, 10-16 strings does not exceed 60V, and the balance of 3-5 strings of batteries does not exceed 75V. Voltage overvoltage may bring certain risks.
Balance current via resistor dumping is 1.5A

It is better to move from the high cell to the low cell rather than dump into a resistor, is it not?
4. No balancing except when charging
I was writing a longer than usual post for me in reply to your very interesting post and got timed out and lost it
