Unless you have a very specific need there is really nothing to be gained and much to be lost... extremely short run times. Why would we need batteries that can handle 4+A discharge rates? A Joye 510 atty at 3.7V pulls about 1.7A (all other atties less). Something all 18650 li-ions can handle with about 80% longer runtimes.

A little harder to find this a very good battery with accurate mAh ratings.

DealExtreme: $9.78 TrustFire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries (2-Pack)

A better choice than the more common red UltraFire 3000mAh one.

Also there is no protection circuit because these are 'safer', but in the event of some sort of problem, a short or inadvertent switch activation the protected Li-ions should shut down at about 2.5V, the LiMN's will keep going till empty.
