RELiON RB52 Deep Cycle Lithium Battery

The RB52 is a lithium iron phosphate battery versatile and compact enough to be used in many marine applications, including smaller boats with lower battery requirements, boats that require two of the same batteries and boats with electrical systems designed for just one battery.

Features:

• Lightweight:
  • RELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water
• More Usable Capacity:
  • Lead-acid batteries are typically sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. And, you can use it all and still get substantially longer cycle life
• Long Life:
  • RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of the rated capacity after 3,500 cycles
• Fast Charging:
  • RELiON lithium batteries charge much faster than traditional lead-acid batteries, and they're packed with more usable energy and up to 10 times longer life so you're always ready to go
• Partial State of Charge Tolerant (PSOC):
  • PSOC, which is a killer of lead-acid batteries, does not affect performance or battery life of a lithium battery. Sometimes batteries don't get fully charged, or they regularly operate in a partial state of charge. Either way, you can count on RELiON lithium batteries living a long and productive life
• Temperature Tolerant:
  • Lithium batteries can handle a wide variety of conditions and are even 2.5x more efficient at low temperatures than lead-acid while being able to safely operate up to 149°F (65°C)
• Eco-Friendly and Safe:
  • RELiON lithium batteries are the ultimate clean energy. No gassing, no fumes, and no pollution. Enjoy reliable power, while protecting the environment, using these non-hazardous batteries
