Checking for a balancing circuit would require opening the battery. I doubt it has balancing circuit, when I check 2S packs they are always without.

I am working on the ZNTER.

Great!
If you do not open the ZENTER, I can add a (nice) photo of the circuit board with charger, protection and booster-IC’s. It was easy to open with 2 screws under the wrap.
