Re: Grid El84, Dry Tortugas

Depending on what you call high power, and what your planned operating time would be, you might be surprised at what your power needs are (I’ll bet you won’t need anything like the 50AH that a 105 AH deep cycle LA battery would give you) and how heavy a battery sized to meet those needs would be.toggle quoted messageShow quoted text
In particular LiFePO3 batteries are far lighter and can be drawn down further than SLA batteries. So some careful measurement of how many watt hours you would need and some perusing of the websites of the various LiFePO3 battery purveyors might be useful.
That’s the good news. The bad news is that those LiFePO3 batteries are sort of expensive. But companies have been known to contribute/loan gear to DX expeditions, so maybe an email to Bioenno would get you a battery to use to activate EI84 at a power level higher than 5w.
