If weight is a consideration, why not just use non-rechargeable batteries?
They have higher energy density, and since these are for "emergency" use
only, I don't see any need for these to be rechargeable. Plus, isn't it
easier to verify the health of throw away batteries? (i.e. would using
a second set of nicads just move the problem back a stage?)
