DC-300H Benefits

Benefits of Lithium Deep Cycle Over Lead/Acid

  • Ultra Lightweight: Lithium Iron Phosphate (LiFePO4) is 60% lighter than Lead/Acid.
  • Longer Life: Lithium offers up to 4x the Lifespan of Lead/Acid Battery. 3000-5000 Cycles.
  • 4x Faster Charging than Lead/Acid: Our Lithium battery can charge up to 4x faster than Lead/Acid Batteries. (Use the proper Lithium Charger to achieve this.)
  • Low Self-Discharge: Lithium can hold a charge for much longer than Lead/Acid when no load is on the batteries. Just disconnect the batteries from a load for storage (check charge every 4 months if in storage; keep above 13v).
  • Power Handling Ability: The Antigravity Deep Cycle Battery has the ability to handle higher output Pulse or Rush Current than its competitors.
  • More Usable Energy: Lithium has almost twice the energy compared to Lead/Acid. Meaning 100 Ah in a Lithium Battery can offer almost as much energy as two Lead/Acid batteries because Lead/Acid cannot be fully discharged and Lithium can. For example, our 120 Amp Hour DC120H offers twice the Energy available from a 100 Amp Hour Lead/Acid Battery and 20 Amp Hours more than most Lithium competitors!
  • Space Savings: Being that Lithium has more Energy Density it can take up less space than Lead/Acid for the same Amp Hour Capacity, while reducing weight tremendously.
  • Durability: Much more resilient to vibration, heat and cold than Lead/Acid. Excellent shock and vibration resistance; no liquids or acid inside to spill or drain out. Will not release dangerous Hydrogen while Charging and will not leak liquids that are damaging to your finish or chassis such as acid.

Built-in Battery Management Benefits

  • Full Battery Management System: Our superior on-board BMS protects against accidental damage to the battery and offers automatic Cell Balancing, making for an extra long life.
  • Protection against Over-Discharge: This prevents the battery from being over-discharged which is the leading cause of damage to any battery be it Lead or Lithium.
  • Protection against Over-Charge: Overcharging of the battery can damage the battery rapidly. Our Battery has protection from the cells getting damaged by over-charge.
  • Protection against Overcurrent: This prevents the battery from putting out more than a safe current – excess current can overheat a battery.
  • Short-Circuit Protections: This prevents the battery from Short-Circuiting and causing damage to itself or the User.
  • Thermal Protections: Prevents charging if frozen or overheated.

Environmental Benefits

  • Non-Toxic: Lithium is less toxic, does not have Lead or Acid.
  • Always remember to Recycle your batteries responsibly!

Safety Benefits

  • Short-Circuit Protections built into the battery.
  • Protection Against Damage from over-charge and over-discharge.

  • Integrated Bluetooth Monitoring: Antigravity Lithium Deep Cycle Batteries have exclusive Bluetooth technology that allows you to track your battery status and condition using our free App (available on Apple or Android).

Cost Benefits

  • Long-Term Value: Lithium has a higher up-front cost but in the long run will have a much longer life than Lead/Acid therefore be more economical and save you money over the life of the product. Our batteries also offer several benefits such as the light weight, increased efficiency, built-in Battery Management Protection System, less maintenance, much faster charging and much better performance overall.
  • Extended Battery Life: Antigravity Lithium Deep Cycle Batteries offer the latest technology for the safest, longest life cycle possible – up to 4X the lifespan of lead/acid. Ours have a full BMS for protecting the battery from over-discharge and over-charge, and preventing it from being damaged.
