RELiON RB300 Deep Cycle Lithium Battery - Group 8D

Our RB300 is a lithium iron phosphate battery that's ready to replace your heavy lead-acid battery bank in your sailboat, RV, or solar energy system. It's only 76 lbs. for a true 300Ah lithium battery that provides 100% of its rated capacity.

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
• 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)
• 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
• 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
• Maintenance Free:
  • RELiON 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 Power:
  • Full power available throughout discharge. Voltage does not drop like lead-acid
• 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
• 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
