What are the best batteries to buy for these? Ordering tonight PLEASE HELP >.<
That depends on which Legacy you are getting and if you plan to use the Kick or not...
Mini Legacy w/o Extention & w/o Kick - AW IMR 18350 700mah Li-Ion Battery
Mini Legacy with Extention and no Kick - AW IMR 18490 1100mah Li-Ion Battery
Mini Legacy with Extention & with Kick - AW IMR 18350 700mah Li-Ion Battery
Standard Legacy w/o Extention & w/o Kick - Tenergy 18650 2600mah Protected Li-Ion Battery or AW IMR 18650 2000mah Li-Ion Battery
Standard Legacy w/o Extention & with Kick - AW IMR 18490 1100mah Li-Ion Battery
Standard Legacy with Extention & with Kick - AW IMR 18650 2000mah Li-Ion Battery
So you have a lot of possible configurations and it depends on which one you select as to what may be best for you. If you plan to use the Kick at some point in the future... get the AM IMR types no matter what so you have something that can handle high drain output.
