I was just wondering how the performance of these LiPos compare

more conventional rechargeable lithium 123 cell.

I thought CR123 were /not/ rechargeable?

At 70g vs the 14g of the ones I've been using, I wonder if we are
talking about the same thing?

Nick

I would weigh your cells. They are NOT 14g.
At that capacity they HAVE to be around 2 oz - 40g+


If these are rechargeable 'CR123 equivalents' they certainly weigh a lot
more than 14g - and they are not 3.3v LiFePo technology they are 3.7 v
Li-ion...


FURTHERMORE if they are 1500mAH they are almost certainly NOT
rechargeable viz:

"Non-rechargeable CR123A batteries have nominal voltage of 3.0 volts and
capacity around 1500 mAh. Shelf life of the best CR123A brands is
usually in the 7-10 years range, making these batteries excellent
choices for standby devices like EDC flashlights, security devices,
military applications and similar.

Non-rechargeable CR123A batteries also tolerate high drain currents,
which is very important for high-power devices and for devices that
require plenty of power for relatively short periods of time.

Rechargeable CR123A batteries (or RCR123A batteries) usually have
voltage in the 3.6-3.7 range and capacity in the 500-800 mAh range. Note
that rechargeable 3.0 and 3.3 volts batteries are also present on the
market."
