I have been reading about LiFePO 4 (lithium iron phosphate) batteries being used in Amateur Radio Field Operations. These batteries seem to be very high capacity and can even start a car. One battery pack in particular is the Zippy 8400mAh pack that has been reported to maintain 5 hours of casual SSB operations at 100W. Again, these are just reports.
I have found on eBay some LiFePO4 batteries that can be used to make a battery pack. Most of these batteries are in the 2xxx to 3xxx mAh variety. There are also several pre-made packs that one can get.
I am wondering if such a pack could/should be aboard a boat for emergency use. I do not know the shelf life of these batteries. Their chemistry seem to be somewhat safe unlike some other Lithium type batteries.
Anyone use these? I am thinking of getting the Zippy 8400mAh pack. About $75. One can get a small wet cell for that price. But I think weigh would be a deterrent here.
Thoughts?
