Get Starting Power and Deep Cycle Energy in One Battery This 1500 CCA lithium battery combines starting capability with 300Ah of deep-cycle capacity, giving you one dual-purpose marine battery for cranking and onboard power. Fish finders, pumps, lighting, navigation, and other onboard loads can keep running from the same battery after the engine starts. Charge From Shore Solar or Generator At the dock, use a LiFePO4 charger. Off-grid, charge through solar and an MPPT controller, or use a generator with a DC-to-DC charger. These options let the dual purpose lithium battery work across marine, RV, and off-grid charging setups without tying you to one charging source. Keep 3840Wh Ready for Long Days on the Water This Vatrer 12V 300Ah lithium battery gives you the capacity to keep fish finders, refrigeration, pumps, lighting, and inverter-powered equipment running while you fish, cruise, or stay anchored. You can cover both starting and extended onboard use without building your system around several smaller batteries. Protect Your Battery When Conditions Change On cold mornings or under demanding electrical loads, the built-in 200A BMS manages overcharge, over-discharge, over-current, short-circuit, and temperature conditions automatically. Charging stops below 32°F and resumes automatically as the battery returns to a safe charging temperature. This protection helps a LiFePO4 starting battery handle changing conditions without manual temperature management. Cut Weight and Simplify Your Battery Compartment A crowded battery compartment gets harder to work with once multiple heavy lead-acid batteries and extra connections are involved. This battery weighs 55.23 lbs and measures 15.16 × 7.56 × 9.76 inches, giving you high capacity in a more manageable enclosure. Fewer batteries also mean fewer terminals and cable connections to organize, which is especially useful when space and weight matter on a boat or RV. See Battery Status Right From Your Phone Connect through the Vatrer app to view state of charge, voltage, current, temperature, operating status, and cell information from your phone. You can check your lithium marine starting battery before heading back to the dock or while onboard equipment is still running. 5000+ Cycles for Fewer Battery Replacements Because this lithium cranking battery also handles regular deep-cycle use, Grade A LiFePO4 cells support more than 5,000 cycles, helping reduce replacement frequency over years of repeated use. Fewer replacements can also reduce the long-term cost and maintenance involved in battery ownership. Expand Your System When Your Power Needs Grow Your current setup may only need one battery, while a future RV, solar, or off-grid system may need more stored energy. This 12V 300Ah LiFePO4 battery can be combined in series and parallel as your system grows, with a full configuration reaching up to 61.44kWh. You can add capacity later without changing to a different battery. Make One Upgrade Do More Choose Vatrer when you want to simplify a starting and deep-cycle setup without giving up either function. Upgrade to the Vatrer 12V 300Ah lithium battery now so your next drive, fishing morning, or off-grid stay begins with dependable power already in place.
