If you want more durable batteries than LiPo's, the A123's are a very good choice. They are housed in a decent thick aluminum can, it looks like 1/32 inch. THese are very durable in every respect... charging=tough, physical abuse=tough, low voltage cut-off= don't need it, incombustible chemistry makes these the choice for someone who wants the ultimate in durability.
They are typically cheaper than LiPo. They are more 'bulky', so for a given mah rating, you can run out of room quick. The most you want to use with A123's is 4600mah, or 2 parallel cells, as they are 2300mah each/3.3v, 72 grams.
