Hello I dont know if this is in the correct place. I just got a 306b and have a question. I am charging 2x SMC 7200mah 2s batteries using a parallel board. I am using the balance charge setting with 14.4 amps and 2s(7.4v) When I start the charging the voltage goes up to 8.8volts!!!! I stop the charger at once, I have doubled checked all the setting multiple times now and it goes up to 8.8volts everytime and i promptly stop it. Is this normal and safe or am I gonna blow stuff up?

Thank You!
