  • RELiON RB20 Sealed 20Ah 12.8V LiFePO4 Lithium Iron Phosphate Deep Cycle Battery
  • Features:
    • Maintenance Free: Plug, play, and charge. No watering, no corrosion.
    • Lightweight & Easy to Transport: Compared to other battery chemistries, RELiON LiFePO4 batteries provide the same or greater energy at less than half the weight and size. This means more flexibility and ease of use!
    • 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 so you’re always ready to go!
      Partial State of Charge Tolerant: Partial charging does not affect performance quality or battery life. A low self-discharge rate means worry-free storage so even occasional users can be assured of reliable performance.
    • Constant Power: Full power available throughout discharge. Voltage does not drop like lead-acid.
    • Eco-Friendly & 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.
