We understand that it’s a bold statement to say that our Deep Cycle Battery is the best on the market… but we truly believe that it is! If you’re looking for a high-quality and reliable battery for your RV, boat, or solar setup, Antigravity Lithium Deep Cycle Batteries are the way to go. Our batteries are extremely lightweight and come with features that give you more usable energy and better performance.

They’re also built to last much longer than lead/acid batteries. Plus, our intelligent battery management system (BMS) is built-in for full protection and ultimate safety. When you combine all of these factors, you’ll see why we believe ours is the best Deep Cycle Battery ever!


Lithium-Ion batteries are significantly lighter than lead/acid versions – up to 75% lighter, in fact. This weight savings helps to make your vehicle more efficient, resulting in better mileage and a number of other performance benefits. Installation is also much easier with a lithium-ion battery, and if you need to move the battery around it’s a simpler process. Antigravity Deep Cycle Batteries only weigh ~26 pounds but they offer 30 to 40% more usable energy than lead/acid batteries of the same Amp Hour capacity – making them a great option for those looking for a powerful battery that won’t weigh them down.


Lithium batteries boast TWICE the energy of Lead/Acid batteries, because Lead cannot be fully discharged while Lithium can. Comparing a 100Ah Antigravity Lithium battery to a 100Ah Lead/AcidDeep Cycle Battery, our Lithium version will supply anywhere from 30 to 40% more useable energy. Although both batteries are rated at 100 Amp Hours, this is possible because a Lead/Acid battery can only be safely discharged to 50%-80% of its rated capacity (depending on the quality and age of your battery), or in other words – you’re only getting half the power out of a Lead/Acid battery that you could be getting out of a Lithium battery.

Lithium batteries also have a shorter discharge time than lead/acid batteries – meaning that they can provide a higher current for a shorter period of time without losing as much capacity. Lead/acid batteries, on the other hand, have a lower voltage when they’re almost depleted whereas lithium batteries maintain a steadier voltage until they’re completely discharged.


Once you’ve used up your battery power, you’ll need to recharge it. And our Lithium Battery can recharge up to four times faster than a Lead/Acid Battery using the same charging current. This is because lithium is more efficient at accepting the energy coming into it, and a Lithium Battery doesn’t require the Absorption Phase that’s necessary to get a Lead/Acid battery to 100% charged.


Our Antigravity Deep Cycle Batteries have a longer lifespan than most batteries on the market. Antigravity Batteries uses only the highest quality Lithium Ion cells that are UL and IEC Listed and are rated at 4000-5000 cycles; whereas, a Lead/Acid battery only averages from 500 to 1000 cycles at best. Please note that a cycle is defined as a full discharge and recharge of the battery. With our Antigravity Deep Cycle Battery, you can rest assured knowing that you’re getting a quality product that will last longer than other batteries.


Lithium batteries are the best choice for applications that require a durable battery because they are much more resistant to vibration than lead/acid batteries. They are also less prone to heat damage.
