Choosing between marine electrical batteries lighting options often comes down to how you plan to use the battery on the water. The two 12V choices here take different paths: the 12V 60Ah LiFePO4 Lithium Battery is lower-priced and much lighter, while the Interstate Batteries Marine/RV Group Size 24 Dual Purpose AGM Battery brings serious cranking power and a dual-purpose design. If you need one battery to run sustained deep-cycle loads, or one that can start a motor and still power trolling, this head-to-head will help you pick.
Quick Verdict
- Choose the 12V 60Ah LiFePO4 Lithium Battery for sustained marine/RV accessory power, a $109.99 listed price, and roughly 12 lb of weight.
- Choose the Interstate Batteries Marine/RV Group Size 24 Dual Purpose AGM Battery when motor starting and trolling power have to come from the same 12V battery.

A Closer Look at Each Battery
12V 60Ah LiFePO4 Lithium Battery, Deep Cycle, Perfect for RV, Marine
If your priority is hours of deep-cycle use without hauling a heavy battery around, this LiFePO4 option is a strong fit. It costs USD 109.99, weighs roughly 12 lb, and measures 7.70 x 5.10 x 6.30 inches, so it can fit in tighter spaces. The 60 Ah rating and 768Wh of energy support sustained discharge for marine and RV accessories through a 50A BMS. Plan to use a 12V lithium iron phosphate charger, and keep series and parallel connections at four batteries or fewer as outlined. The battery can also accept charge from solar with a charge controller, a battery charger, or a generator paired with a LiFePO4 charger. If your boat relies mostly on deep-cycle power rather than engine starting, this lithium battery gives you a lighter way to get it.
Interstate Batteries Marine/RV Group Size 24 Dual Purpose AGM Battery 12V 70Ah
The Interstate battery is the choice when one unit has to do two jobs. It is a dual-purpose AGM built as both a cranking battery and a trolling battery, so the motor can start and accessories can run whether the motor is on or off. It delivers 70 Ah, 750 CCA, 940 MCA, and 140 minutes of reserve capacity. At USD 259.95, it is the higher-priced option, and it is heavier and larger at 44.6 lb with dimensions of 6.81D x 11W x 8.98H, so it is less convenient to move around. It also includes a 24-month free replacement warranty and a claimed service life longer than conventional alloy AGM and flooded batteries. For boaters who want starting confidence and trolling power from the same battery, this AGM is the practical pick.
Final Choice by Use Case
Choose the 12V 60Ah LiFePO4 Lithium Battery if you want a lower listed price, lighter weight, and a deep-cycle battery for RV or marine accessory loads. Choose the Interstate Batteries Marine/RV Group Size 24 Dual Purpose AGM Battery if you need one battery that can start the motor, run a trolling motor, and support accessories without adding a second battery.
