The generator will charge a 3s Li-Po, the std system without BMS just charges the ECU pack and it stops at 90% so balancing is not so important. I’m 10 months with my 220Rxi and I’m yet to charge the ECU pack and I check the balance periodically and the pack is still balanced.

The output is enough to fill the pack back to the starting point in a seven minute flight, before you shut the turbine down.
