Britmar Distributes New Super B Lithium Iron Phosphate Batteries

Super B’s new lithium iron phosphate battery packs power in a smaller footprint.

Britmar Marine Ltd., of North Vancouver, B.C., is the North American distributor for the Nomada 12V105Ah, a rechargeable 12-volt battery with the capacity for 105 amp hours.

Although it can be used for household electric power, the traction battery has proven to be especially popular for emergency power for vessels, said Jurek Makarewicz, who manages technical support and sales for Britmar. It works for both all-electric and hybrid diesel-electric power systems, he said.

Although many companies are already familiar with the advantages of lithium-powered batteries, the Nomada’s new, smaller, light-weight, high-density design offers additional benefits in contrast with 160 amp-hour batteries. “Four of the new ones fit into the footprint of one of the old ones, giving four times the power,” Makarewicz said.

The battery also uses safe lithium technology and includes an integrated battery management system, terminals for two M8 bolts, wired communication interface, battery monitoring/history usage and adaptive cell balancing and is configurable in a serial or parallel connection. Up to 60 batteries can be configured in a series.

“Super B batteries are based on lithium iron phosphate technology,” a data sheet for the new product announces. “This is the safest lithium technology available today. On top of that, our bespoke casing and electronics further increase safety and durability.”

Makarewicz further praised the battery’s lithium iron phosphate (LFP) technology, saying it has a much higher thermal runaway temperature than nickel manganese cobalt oxide and lithium cobalt oxide batteries and, as such, does not require an expensive cooling system. When burning, LFP can also be put out with water, where other types of batteries need special chemicals and can be difficult to extinguish as they produce oxygen when they burn.
