LiPo vs LiFe battery longevity
 

So ive done a little digging and from what ive read LiFe batteries "last longer" then their brothers the LiPo. However I'm uncertain if this is for same MaH rating or same physical dimension size battery. From the websites i looked at a LiPo has a higher MaH rating then a similarily sized LiFe battery.

so my question is wiether a LiFe of similar dimensions but lower Mah will put as many BB's downrange as a LiPo. Im guessing this is a dumb question so be nice :)
