what cable/balance board do I need for the 1210 hyperion

It appears that charger doesnt have a built in balancer as such, and instead requires you to buy an LBA 10 and dataport cable, plus the balance adaptor for your lipo's cell count:

You will also require the correct balance adaptor board, but without knowing what brand of balance plugs your lipos use, I cant say which one you need- they are listed in the 2nd link, though heres the jst-xh (align style, used on hobby city lipos) as an example:
