Battle Born LiFePO4 Deep Cycle Battery - 50Ah 24v with Built-In BMS - 3000-5000 Deep Cycle Rechargeable Battery - Perfect for RV/Camper, Trolling Motor, Marine, and Off Grid Applications

  • BUILT-IN BMS: BMS stands for "Battery Management System" - the brain of our deep cycle lithium batteries. Our BMS protects your battery from most common causes of battery failure, such as temperature volatility or ground faults. The BMS regulates the amount of power taken out of the battery and acts as a shut-off system to protect the li-ion cells (and you) from unsafe operating conditions..
  • LITHIUM ION TECHNOLOGY: Unlike Lead Acid batteries, Battle Born's deep cycle lithium ion batteries have unlimited mounting capability, exceptional longevity, and are more cost effective. When factoring time and cost into your purchase, our lithium ion battery banks come out ahead every time. Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults..
  • GREEN ENERGY BATTERIES: Made from 100% safe, nontoxic, renewable energy, Battle Born Batteries last for more cycles and can be charged and discharged repeatedly (and charge faster than any other battery). We make our renewable, sustainable green energy batteries because they’re simply better than anything else out there, including other green batteries..
  • LIGHTWEIGHT AND VERSATILE: At a sleek 29 lbs, our 50Ah 24v battery weighs in at only 1/3 the weight of lead acid ba....
