Features

  • 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 31 lbs, our 100Ah 12v battery weighs in at only 1/3 the weight of lead acid batteries! With no acid in the battery, you're able to safely mount in any position. This makes li-ion batteries perfect for marine, RV, campers, golf cart, off-road and off-grid applications!
  • BUY WITH CONFIDENCE: Proudly designed and assembled in the Reno, Nevada - the epicenter of the lithium ion battery world. We test (and re-test... and re-test again) literally every battery we ship and all of our batteries come with an industry-leading 10 year warranty. We believe you should be as confident in your battery as we are.

    There are some things you should consider when buying a marine deep cycle batteries. We spent 22 hours researching the most important things you should consider when buying a marine deep cycle batteries. So should we start with the list of things you should consider?

    1. Budget

    Make a list of the things you want in your marine deep cycle batteries and the price you are willing to pay for it. So try to look for a product in that price range and choose the one that appeals to you the most. One tip we would like to give you is: don’t settle for a cheaper product if it doesn’t even have a function you need.

    Most marine deep cycle batteriess fall within the price range of $ 299.99 to $ 949. Therefore, if budget is not a problem and you want the best product for your needs, we advise you to choose the Optima OPT8016-103 Batteries D34M BlueTop Starting and Deep Cycle Marine Battery.

    2. Does it have all the features you need?

    Most importantly, the marine deep cycle batteries you are purchasing should have all the features you are looking for. In case you don’t even have one, don’t buy! We are saying this because you will not be able to use it for that purpose. If you are a person without budget problems, I would suggest you to choose the best model which is Battle Born LiFePO4 Deep Cycle Battery – 100Ah 12v with Built-In BMS – 3000-5000 Deep Cycle Rechargeable Battery – Perfect for RV/Camper, Marine, Overland/Van, and Off Grid Applications
