Firefly’s award-winning technology improves upon lead-acid batteries with unmatched performance and lifespan in deep charge and discharge cycling. Carbon Foam shares most of Lithium-Ions benefits over traditional Lead-Acid batteries for less than half the price.
The patented Microcell carbon foam design solves the leading causes of failure in lead-acid batteries by resisting sulfation and corrosion, making it a more reliable and longer lasting battery than any other lead-acid battery on the market.
The battery’s cells produce less localized corrosion and wear while utilizing active materials more effectively overall compared to a traditional cell. The long lifespan and low cost of the Carbon Foam batteries means every dollar stretches for the most cost-effective power storage available.
These batteries are best in their class for Kilowatt-Hour capacity, and with 100% Depth of Discharge, this powerful battery can compete with batteries twice its size with an average 50% D.O.D.
Partial State of Charge Resilience
The Carbon Foam battery can recover from partial state of charge abuse and extended storage in a discharged state without any loss of capacity.
These batteries are able to charge to 100% of their rated Amp-hour capacity even after weeks of battery abuse. They are able to operate for long periods of time in Partial State of Charge (PSOC) while still enjoying the most of their long life and high capacity.
Their excellent recovery from storage makes them the ideal battery for occasional excursions off-grid or for powering cabins which are only used for part of the year. Carbon Foam is the perfect solution for adventurers who are always on the move or for those who experience especially shady or rainy conditions. Fill up the batteries whenever the occasion strikes without losing any capacity.
The Carbon Foam batteries are able to charge 30% faster than competing AGM batteries thanks to their improved technology. They can be charged at a boggling 250 Amps: ten times higher than average.
These remarkable batteries are also capable of a fast discharge, capable of cold cranking 720 Amps despite being deep cycle batteries.
These batteries are non-gassing and require no maintenance, which make them the safer choice for marine and high temperature applications. Firefly’s Carbon Foam batteries are the well-tested superstars of the marine battery world.
In testing done by Rodd Collins of Compass Marine for Practical Sailor, the Firefly Oasis was the only AGM battery able to return to more than full capacity after a month of abuse in partial state of charge cycling.
Another field test by Nigel Calder proved similar results after an even longer period of time.
“In preliminary testing I worked the Firefly batteries hard in a real-world (onboard, while cruising off the west coast of Scotland) partial state of charge operation. The goal was to minimize engine run times and optimize electrical system performance in an ‘off-the-grid’ situation with limited recharging opportunities. The kind of operating regime I followed spells death for most lead-acid batteries. In contrast, after two months of intensive cycling, the Firefly batteries tested out with 100% of the capacity with which they started. These are encouraging results which, if substantiated over longer periods of time, represent a ‘game changer’ in terms of lead-acid technology and boat electrical systems design. I look forward to collecting more data.”
Firefly Oasis batteries are suitable for uses with RVs and trailers, marine applications, defense, mining, transportation and vehicles, and off-grid housing.
