Lithium battery 12V 300 Ah 3.84 kW
Introducing our newest powerful battery. This thing is a beast! AIMS Power 300A 12V Lithium Iron Phosphate Battery (LiFePO4)
Engineered for versatility, safety, and reliability, this advanced battery is packed with innovative features:
- Built-in Heater & Wake-Up Functionality: Enables efficient charging in cold temperatures and simplifies recovery of over-discharged batteries—no need for external jumpering.
- Stable Performance: Maintains constant output voltage, delivering virtually full power until fully discharged, reducing the need for voltage regulation circuitry.
- Longer Cycle Life & Easy Maintenance: LiFePO4 technology offers better thermal and chemical stability, ensuring longer service life and enhanced safety.
- Compact Yet Powerful: Fits seamlessly into existing 12V battery spaces, replacing lead-acid, AGM, or gel batteries in applications like RVs, golf carts, boats, commercial vehicles, and off-grid systems.
- Reliability You Can Trust: Backed by a lifetime prorated warranty (<3500 cycles) for safe, reliable, and powerful performance.
Enjoy constant output voltage, superior thermal stability, and extended battery life in a lightweight, compact design. Perfect for replacing lead acid, AGM, or Gel batteries in RVs, boats, golf carts, off-grid systems, and more.
Why AIMS Power?
Transparency and accuracy define our commitment to quality. We ensure our lithium batteries deliver the amp-hour capacity and performance we promise. While lighter than traditional batteries, our products are meticulously designed to meet the lithium density threshold required for optimal performance. Discrepancies in weight can compromise capacity, so we encourage informed choices.
