THE HOLY GRAIL

Lithium-ion batteries have several times the energy storage capacity of an equivalent volume and weight of lead-acid batteries, and can be charged at extraordinarily high rates of charge to very high states of charge. They can be discharged almost totally without damage anywhere from hundreds of times to thousands of times. They are immune to sulfation and as such can be operated permanently in a partial state of charge.

Whereas the most efficient lead-acid batteries (AGM) are only 85 percent efficient at converting electrical energy into chemical energy and vice versa, lithium-ion is better than 95 percent efficient, resulting in far less heat generation during high-rate discharges and recharges—an important consideration with my current high charge rate experiments. This is an amazing set of positive characteristics. There are, however, some potential negatives.

PREVENTING FIRES

Every lithium-ion battery currently in the marine marketplace contains a flammable electrolyte, and all lithium-ion batteries can be driven into

Home Is The Sailor
I am sailing with Robin Lee Graham, but there is no wind. It’s a hot day in July and Montana’s Flathead Lake is glass. The mountains around us are blurred by haze. A wildfire burns to our east. Robin’s blue eyes light up—he’s spotted catspaws ahead.

Hh44-sc
Good things come to those who wait, and sailing the HH44-SC confirmed the adage. Even under delivery sails—and only a main and genoa, at that—we fairly flew across the Chesapeake Bay on a breezy fall day after the U.S. Sailboat Show in Annapolis, whe
