9118Re: [GPSL] The Old Battery Packs
- Jan 1, 2011Hi Joe,
Those were outdated LiSO2 primary cells, originally rated at 7 AH, but back
in the '90's, we ran a "typical EOSS payload" test on 'em (500 - 750 mA, IIRC)
and got 4AH out of a 5S pack before the loaded voltage dropped below 12.0V.
BTW, those easy-to-open surplus packs are extinct, so far as I was able to
figure a couple of years ago; that's why we switched over to Li-ion 18650's.
I think you can still find some of the newer plastic-cased packs with the
same cells, but they run over $100 apiece and they're a booger to harvest
I have a huge pile of partially discharged cells under my bench that I've got
to drain and dispose of. Any takers? :=)
