AGA Lithium iron Phosphate 12V 50Ah LiFePO4 Deep Cycle Battery

The AGA 50Ah battery is made to replace your existing SLA with the same form factor and size, just half the weight and almost 3X the operating times! This 50Ah battery is LiFePO4 chemistry (Lithium Iron Phosphate). LiFePO4 are the safest, longest lasting Lithium Batteries available with 2000+ charge cycles. All batteries have built in BMS which gives you charging and discharging cutoff protection for your safety and increased longevity of our products. Our batteries run in various systems, including marine, RV, van, and off-grid! It’s time to upgrade your heavy lead-acid batteries to LiFePO4 batteries and upgrade your lifestyle and ability to adventure!

 LiFepo4 Battery Highlights

Compared with traditional AGM/GEL/VRLA/Lead acid batteries, LiFePO4(Lithium iron phosphate) batteries are:

  • Higher safety and stability:non-toxic, non-polluting, no rare earth metals, no explosion, no fire.
  • Super Long Cycle Life: 10 times of Lead acid battery’s cycle life – At least 2000 cycles at 100% Depth of Discharge
  • More usable capacity: up to 100% usable energy
  • 1/4 lighter than lead-acid batteries.
  • The LFP battery can work in a wide temperature range from -20 to +60°C
  • Built-in BMS ensuring battery safety and efficient operation
  • Environmentally Friendly: LiFePO4 battery is a green battery and it doesn't contain any heavy metals and rare metals, and are better environmental friendly.
  • No memory effect.
