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.
Tech Specs
Perfect for the space I had available. Great size for 300ah.
Have only been using on my boat for about a month but am completely satisfied with the battery and the blue tooth bms. I can run my fridge via 1000watt inverter as well as all 12v lights and accessories for roughly 3 days without any use of my solar panels.
This battery was an additional one to the two I purchased back in September to add to my 5 wheel for my solar system, the bluetooth is a plus on this one, so they have been great, I would highly recommend
Excited to build out my boondocking setup and these batteries are spec’d well and very affordable. We are full time RVers and hoping this unit works well so I we can puchase 3 more to complete the setup.
Battery fit in boat with little room to spare after moving the started battery, listed dimensions are accurate. Appears to be well built and good reviews from YouTube videos that disassembled and commented on built. Fast shipping and well packaged. Charging now and headed to the lake soon, excited to lengthen fishing time. Minus one star for bolts becoming difficult to tighten down at the end.
We replaced 2 old large marine batteries in our 46' Catamaran with 4 of these new ones and we an add one more if needed. They are powering everything we need and hold charges really well.
I am happy with my purchase. I do like using the app to check the battery status. So far so good.
Impressed with the build quality after watching several videos. They are a good value for the AH provided. Shipping was quicker than expected. They are a big upgrade for our van and seem to work well so far.
Light weight with high power density, and at a price and performance that beats most competitors.
these batteries are fantastic! So far they have performed well and the 300AH in parallel have remained in balance.
FAQs
Yes. We designed this dual purpose marine battery to crank a compatible 12V marine engine and continue supplying deep-cycle power to onboard electronics and accessories. Use the Vatrer app to watch SOC during long days on the water and preserve enough charge for the return start.
Our 1500 CCA lithium battery is built for compatible 12V marine engines with starting requirements within its 1500 CCA rating and support for LiFePO4 starting batteries. A starter draws the current it needs, so having available cranking capacity above the engine's minimum requirement does not force excess current into the starter.
For engine-driven charging, we recommend a LiFePO4-compatible DC-to-DC charger or a properly regulated lithium charging system between the engine charging source and battery. This controls the charging voltage and current instead of treating the 12V 300Ah LiFePO4 battery like an AGM battery on an older or unregulated charging system.
Use your existing charger only when it has a LiFePO4 charging mode compatible with a 14.6V battery. Otherwise, switch to a dedicated LiFePO4 charger and avoid lead-acid equalization or desulfation modes.
No. This battery uses low-temperature protection rather than self-heating. Charging stops below 32°F and resumes at 41°F, so warm the battery in an insulated or heated compartment before charging when temperatures remain below freezing.
Yes, as long as the combined continuous current stays within the battery's 200A output limit. Run the trolling motor and sensitive electronics on separate fused circuits, keep motor wiring away from sonar cables, and use Bluetooth monitoring to track remaining capacity during the day.
Start with the battery's 3840Wh energy capacity and divide it by your average load in watts. A 300W average load gives about 12.8 hours before wiring or inverter losses, so subtract some runtime for conversion losses and keep additional energy available when the battery is also handling engine starting.
The built-in BMS supports up to 200A continuous discharge, so keep the inverter's battery-side continuous draw below that limit and leave headroom for startup surges. This makes the 12V 300Ah lithium battery suitable for substantial inverter loads without sizing the inverter beyond what the battery can continuously supply.
Yes. You can charge this dual-purpose lithium battery from solar through an MPPT controller set for LiFePO4 charging. This is especially useful for replenishing energy used by fish finders, lighting, refrigeration, and other onboard loads while the boat is anchored or stored between trips.
The battery measures 15.16 × 7.56 × 9.76 inches, so plan the compartment around that enclosure plus clearance for terminals and cable bends. Secure the battery against movement and keep the connections accessible for installation and service.
