    How a Lightweight Deep Cycle Battery Boosts Performance

    Ever seen a picture of the first computer? The ENIAC, built during World War II, was humongous. It weighed a whopping 30 tons! Imagine putting that on your desk…or lap. Thank goodness for the lightweight computers we have nowadays.

    Batteries have gone through a similar evolution from heavy to light. But so many folks are sticking with heavy lead acid batteries, because that’s what they’re used to. It’s time they knew what a lightweight deep cycle battery can do for their boat or RV’s performance!

    Curious to learn which deep cycle battery deserves the lightweight trophy? The one that weighs 75% lighter than lead acid but is also considered the safest among lithium batteries?

    Read on to discover the answer, plus the advantages it can have for your boat, RV, golf cart, or other application.

    The Lightest Deep Cycle Battery on the Market

    So, who deserves the title for ultra lightweight yet incredibly safe, when it comes to deep cycle batteries? Here’s the answer: Lithium LiFePO4.

    Why is it so light? It all comes down to chemistry. Lithium LiFePO4 batteries are made of lithium iron phosphate. You might recall from science class that lithium is one of the lightest elements. Lithium batteries are made of materials that are less dense. This allows them to store a lot of energy for their weight.

    That’s what makes lithium deep cycle batteries much lighter than other rechargeable batteries of the same size. Up to 75% lighter than lead acid, in fact. So if you want a lightweight deep cycle battery, Ionic lithium is among the best types you can find. But what would you want a lightweight battery for? We’re glad you asked! Keep reading for the answer.

    Lightweight Deep Cycle Battery Advantages for Your Boat

    A light deep cycle battery is great for many applications. But boats are one of the vehicles that benefit from a feather-light battery the most. Especially small ones, like fishing kayaks. For those, you’ll definitely want to use the lightest deep cycle battery you can find.

    Why do you need a lightweight deep cycle battery for a boat? Well, at the risk of stating the obvious, boats have to float. Hefty cargo makes them sink a bit in the water, dragging down speed. More weight also means more fuel consumption.

    So if you reduce the weight of your battery, drag is reduced. You’ll save on fuel and changing direction will be a cinch. You can maneuver your boat with greater ease. The change might be so dramatic that it will feel like you got a new boat!

    You might also feel like you got a new back, once you stop hauling around a bulky battery. Lithium marine batteries can be charged right on the boat with a smart onboard charger. But should you have to move it for any reason, a lightweight deep cycle battery is going to save you a few bucks on Bengay and ibuprofen.

    Advantages for Other Applications

    Of course, not everyone uses their lightweight deep cycle battery for a boat. They’re also great for RVs, UTVs, golf carts, solar setups, and more. For these applications, there are plenty of advantages to having a lighter battery. For example:

    • Save on fuel costs by making your vehicle lighter.
    • Easy to move around and install.
    • Compact enough to fit into small vehicles like UTVs and golf carts.
    • Makes vehicles easier to maneuver.
    • Saves weight and space for other gear you might need to carry.

    Other Benefits of A Lithium Lightweight Deep Cycle Battery

    Normally you’d call someone a lightweight if they can’t handle much. So does a lithium lightweight deep cycle battery skimp on other areas? No way. You’ll get just as much energy (or more) with a lithium battery as you would from a traditional battery of the same size. Being small and light doesn’t make a lithium battery flimsy. Quite the opposite.

    Lithium batteries can handle a lot more charging/discharging cycles than traditional batteries. This means they will last a lot longer–we’re talking around five times longer than lead acid batteries. Most traditional batteries will last around 2-3 years, but lithium batteries last around 10.

    When you choose Ionic LiFePO4 batteries, you’ll also get these “smart” functions:

    • Fast, efficient charging. (Up to 4x faster.) Lithium accepts energy faster than other batteries.
    • Low self-discharge rate (Only 2% per month). Lead acid batteries self-discharge at a rate of about 30%.
    • Bluetooth monitoring. See how much longer your battery will take to charge, how much charge it has left, and other stats on your smartphone.
    • BMS (Battery Management System). That’s BMS, not “BS”. Because this system makes sure you never have to deal with any “BS” like overcharging and short circuiting.
