No, I didn't put the TC Charger control circuit on the Master board. The reason was just that I made the Master board before I knew what charger I was going to use. I ended up making a small extra board for the charger PWM control. The circuit I used was straight out of the TC Charger user manual.

Yes, this BMS is cheap enough to use even on small batteries!
Having said that, it sounds like BMSs are less important on smaller batteries. The more cells you have in series the more likely they are to get out of balance. Can you measure the voltage on individual cells in your batteries? If so you can get an idea of how unbalanced they are now...
