[PSUBS-MAILIST] Lithium batteries

[David Colombo via Personal_Submersibles]

Hi Scott,
Two years ago the cost was $7000 for a single battery when I attended the
UI convention. They might be cheaper this year. Want me to pick you up  a
couple, I know they are supposed to be at the the Ui event this year as
well. Wy and I will be attending. I will need a bigger suit case to bring
them home however.



Best Regards,
David Colombo
