i have a hyperion 1210i charger with powersupply. I have a 2s maxamps 6000mah pack coming. Do i have to buy a balancer for it?

If your asking if it has an internal balancer, then the answer is no. If you want to balance your cells then you must use an external one. The Hyperion LBA10 balancer works well and can hook up to the Hyperion chargers to show the individual cell voltages on the chargers display.

Personally, I always balance my cells when I charge. At $40 an external balancer is a cheap safety measure.
