Upgrade your lead acid battery bank to lithium ion technology! With SeaPack LiFePO4 battery packs you will get 2000 to 3000 cycles versus the 300 to 500 cycles of a lead acid--at least 5 times the life of a lead acid bank. Lead acid recharges require 8 to 16 hours, SeaPacks can charge in less than an hour and still deliver more energy than lead acid.

ARC3, makers of lithium ion battery packs, presents a green way to power your watercraft. No more acid spills, no more fumes. Fully recyclable, our batteries will last longer. That means fewer throw aways. Faster charge times mean less time recharging from your gasoline onboard generator.
