[PSUBS-MAILIST] Lithium batteries

[Seaquestor via Personal_Submersibles]

Hi Alan, what voltage value are you us r in to build your array? I think I would would need 10 -12 batteries to achieve the 36 volts. Potential max thruster amp draw, 190a - 240a. , average draw 40a. Needed run time 8 hrs. What battery would you use?

Tired, forgot to post the link.

  Scott, I presume you are talking about keeping the weight down "under the water,"
in which case if you went with battery pods instead of compensating, there wouldn't 
be much difference, as you are putting square batteries in to round
battery pods & there would be a lot of air space that would counter the weight of the pod.

WOW that's expensive.
These Thundersky batteries are a good option.
I remember Herve Jaubert saying he was using them in his ambient's,
but in a battery pod, not compensated.

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.

Iam not sure about that battery Scott,
but these are pressure resistant & have a compensation module.
