I was just wondering how the performance of these LiPos compare with a
more conventional rechargeable lithium 123 cell.

I thought CR123 were /not/ rechargeable?

I've been using rechargeables like these:
in cameras for years.

I'm not sure of the correct prefixes or suffixes for them so I
deliberately avoided that. They weigh about 14g and have a capacity of
about 1500mAh compared with the LiPos I have which seem to be just
over 10g and, as I said 200/350mAh


Apples and oranges - you have about 5 Wh there. (3.3 x 1.5)
And I am certain they don't weigh 14g

40g is more like it

This 5Wh LIPO pack

weighs in at 26g

I have an electronic balance which measures in 0.1g intervals and is
accurate to +/- 0.1g (according to reference weights). The 123 cells
each weigh something between 13.8-14.0 grammes, the little helicopter
LiPo about 10.2g.

These 123s say Li-ion and 3.7v on the sleeve.
