This Group 8D RELiON RB300 12V 300Ah LiFePO4 Lithium Battery fromNomadic Supply Company® is ready to replace your heavy lead-acid battery bank in your sailboat, RV or solar energy system. The RELiON RB300 12V 300Ah LiFePO4 Lithium Battery is only 82 lbs for a true 300 Amp Hour lithium battery that provides 100% of its rated capacity. The RB300 gives you the flexibility to replace several small, heavier lead-acid batteries in a single high-capacity unit.Group 31; 12 Volt; 300 AH Capacity; M8 Threaded Stud Top Terminals; Lithium Iron Phosphate; 20.6 Inch Length; 10-1/2 Inch Width; 8.7 Inch Height; Deep Cycle Battery; ABS Case Material

RELiON RB300 12V 300Ah LiFePO4 Lithium Battery Features:

  • Lighter Weight: 50-60% less weight than lead-acid equivalent
  • Longer Life: RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of rated capacity after 2,000 cycles
  • Constant Power: Full power available throughout discharge. Voltage does not drop like lead-acid
  • More Usable Capacity: Lithium batteries allow you to use 100% of their capacity, regardless of the rate of discharge
  • Maintenance-Free: Plug, play and charge. No watering

LightweightRELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.Temperature TolerantLithium 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).Fast ChargingRELiON 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!Long LifeRELiON 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.Maintenance FreeRELiON lithium batteries are maintenance-free – no watering, no corrosion. Low self-discharge means the batteries don’t lose capacity when they’re idle, assuring that you have the energy you need, every time you need it.Constant PowerFull power available throughout discharge. Voltage does not drop like lead-acid.Partial State of Charge TolerantPartial state of charge, known as 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.More Usable CapacityLead-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. Plus, you are typically cautioned to limit your use to 50% of the rated capacity, as using more can significantly reduce performance. 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.
