These new Impulse cells are rather good. All (or many) are the same as the new Hyperion cells, but are less expensive. Believe it or not, the Impulse 2100mah cells are most likely the same thing as the TP Prolite 2100mah cells :eek:, but at a fraction of the cost! This means that you can get TP performance and low weight for much less:

The difference in size and weight comes from the pack construction; the Hyperion and Impulse have foam padding, and the TP don't. Internal construction may also be different. It is just incredible that you can get a TP 3s 2100mah (15C) pack for $10 from Hobby People (the Impulse pack), or $12 less from the other website!

David, you gotta start taking advantage of that employee discount :cool:.
