RELiON Lithium Batteries


RELiON Lithium Iron Phosphate (LiFePO4) Marine batteries offer lightweight, safe and high power energy solutions for your watercraft. These dual purpose, maintenance free batteries provide more power than traditional lead-acid batteries, are long-lasting, and designed to perform in harsh conditions–freezing cold, scorching heat or rough waters.

LiFePO4 Technology Benefits:

  • Significantly less weight
  • 10x longer life span than traditional lead acid batteries
  • Low resistance and fast recharge rate
  • Green energy source with zero emissions
  • Greater energy density, twice the battery capacity in the same amount of space
  • Operation under temperatures ranging from -40 to 158 degrees Fahrenheit

RELiON Advantages for Marine Applications:

  • Faster Recharging: Charging your marine battery is easier and more efficient when you choose lithium technology. Because lithium marine batteries only have two charging stages - as opposed to lead acid marine deep-cycle batteries three-stage charing - RELiON batteries charge in a fraction of the time. This means you’ll be able to get back on the water faster and spend less time waiting for a full battery indication.
  • Lighter Weight: Lithium marine batteries are one-third of the weight of lead acid alternatives, which makes a major difference in your boat’s top speed, fuel efficiency, and draft.
  • Long Life Span: RELiON batteries last 10x longer than a lead acid battery, cycling 5,000 times at 100% DOD compared to a typical lead acid battery that cycles 500 times at 80% DOD. Lithium marine batteries often outlast the boat they’re installed in. 
  • Consistent Power: Because LiFePO4 batteries have a higher voltage output than lead acid alternatives, they maintain a consistent delivery of power throughout discharge. Lithium marine batteries also offer a higher usable capacity, meaning you get more hours of use between charging.
  • Safety: RELiON lithium battery LiFePO4 cell design includes various safeguards including high temp thermal fuse, flame retardant additive and pressure relief valves.
