So, Ihooked up my battery to my Dynam Erazor 450 and it didn't have enough power to spin the motor. I then hooked the battery to the balance charger and it charged like normal for about 10 min, then started making some buzzing sound... Why is it doin this?Do I have a bad charger?

a buzzing sound is an alert. So is there any error msg on the charger? which charge mode did you select? Please let me know more info so I can better help you and understand the situation.

I dont have an option for a mode nor a display..  It is the balance charger that came with the heli

ok do you have voltmeter so that you can measure the voltage of the battery and let me know? I want to isolate the problem and make sure your battery is ok and has no problems.

OK, this is what happened to me this week.

This bird is not for beginners. The manual is very difficult to understand, it's mostly Chinese. I wouldn't call it a RTF. I spent over 2 hours correctly setting it up. The gyro IS NOT a heading hold model. It is a "buffer" at best. The radio is not laid out like other Tx's. Without Youtube and experience, a person could get hurt during the start-up with this radio. Now for the downside. DO NOT buy from "xheli.com" or "nitroplanes.com"(they are the same company). Customer service hung up on me twice when I was unsatisfied with the included charger. Claims(both online and in the manual) are that the charger is rated for 1amp. I spent some time with it and got a maximum current of 350mah. The stock battery, 2200mah, takes 6.5 hours to charge. I spoke with customer service and they said that these figures are within there companies expectations of this charger. When I began reading the manual's details for the charger back to them, they hung up! If only based on the companies attitude, I cannot recomend them and if this is a first chopper stay away from the erazor, or get an experienced pilot to help.
