12V 300Ah Battery More Energy, Less Weight
This Vatrer 300Ah lithium battery features a compact design, a 300Ah capacity, a 12.8V nominal voltage, and offers up to 3840Wh of usable energy. It delivers up to 200A of continuous discharge current, allowing you to confidently power high-load devices such as RVs, yachts, camping or off-grid equipment without worrying about “will it cut out?”
200A BMS Protection. Safer Power Every Trip
You do not want your battery guessing under load. This 300Ah lithium battery uses a built-in 200A BMS to protect against overcharge, overdischarge, overcurrent, short circuits, high temperature, and low temperature, while auto-cell balancing helps keep performance stable over time.
Low-Temp Cut-Off. Ready for Cold Mornings
Cold weather can be rough on batteries, especially during winter RV camping or early-morning fishing trips. This 300Ah LiFePO4 battery automatically stops charging below 32°F, stops discharging below -4°F, and resumes charging at 41°F, giving your system smarter protection when temperatures drop.
Bluetooth Control. Check Power in Seconds
No more guessing from a dim battery meter. This 300Ah lithium battery with Bluetooth connects to the Vatrer app, so you can check voltage, temperature, charging status, and battery health right from your phone while sitting inside your RV, boat cabin, or off-grid shed.
More Power, Less Space
When your RV fridge, lights, water pump, inverter, and small kitchen appliances all need steady power, this 12V 300Ah LiFePO4 battery at only 55.23 lbs and 15.16 × 7.56 × 9.76 inches, it is easier to lift, mount, and wire in a Class C RV battery bay, fishing boat compartment, or compact off-grid cabin setup. One Vatrer 12V 300Ah battery can replace multiple bulky lead-acid batteries.
Expandable Power. Grow Your System
You can build more than a simple 12V setup. This 300Ah lithium battery supports up to 4 batteries in series or 4 in parallel, allowing a maximum 4P4S system up to 61.44kWh, ideal for larger RV solar systems, off-grid cabins, mobile workshops, or backup power setups.
Flexible Charging. Power Your Way
Charge at the campground, in the driveway, or off-grid. With a 14.6V 70A LiFePO4 charger, this 12V 300Ah LiFePO4 battery can recharge in about 4.5 hours, and it also works with solar charging through an MPPT controller or generator charging through a proper DC-DC setup.
Deep Cycle Lithium Battery. Better Value
This deep cycle lithium battery is built for repeated charging and discharging, not just short backup use. If you are looking for the best lithium battery for RV trips, trolling motor power, camping energy, cabin lighting, or home backup, the Vatrer 300Ah lithium battery gives you real usable runtime: about 38.4 hours for a 100W fan, 12.8 hours for a 300W refrigerator, 7.5 hours for a 500W cooker, or 2.5 hours for a 1500W air conditioner. And when you compare the 300Ah battery price, you are not only paying for capacity, you are getting lower maintenance, lighter handling, Bluetooth monitoring, low-temp protection, and a built-in 200A BMS for stronger long-term value.
Upgrade with Vatrer. Power Feels Easier
Choose the Vatrer 300Ah lithium battery when you want serious 12V power without the bulk, maintenance, and voltage sag of old lead-acid systems. You get 3840Wh usable energy, 200A discharge, Bluetooth monitoring, low-temp cut-off, expandable wiring, and 55.23 lbs lightweight handling in one clean upgrade for RVs, boats, camping, off-grid cabins, and home backup power.
TECH SPECS
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.
Haven't used it yet. Package arrived on time and well sealed and protected
So far so good- just installed camper and ready to try it out
I like the battery, it comes with hardware to install, the bluetooth app is good, gives lots of understanding as to how much power is coming in and out. The only negative is mine is mounted on the trailer tongue and almost no battery box can be used, the battery is bigger than anything else out there. I ended up using a dual battery box and it fits nicely.
Haven’t used them a lot yet, but I like them so far
Online ordering went smoothly. Tracking delivery was good and arrived in a timely manner. So far, the battery is working great, is a perfect size, the Bluetooth Android App is working fine also.
Excellent packaging and delivery shipped at 50 percent and charged right up. Left fridge on while using some lights and vacuum occasionally for seven days still had 47 percent charge.
Very usable app. I figured out that it switches from one battery to the other. Now, I am going to set them up in parallel to better suit my needs.
So far so good. First trip is this week, yet all systems seem to be operating perfectly!
FAQs
Yes, but runtime depends on the air conditioner size and inverter efficiency. The Vatrer 12V 300Ah LiFePO4 battery provides 3840Wh of energy, so it can run a 1500W RV air conditioner for about 2.5 hours under ideal conditions. For a Class C RV or travel trailer, it is better suited for short A/C use, overnight essentials, or pairing with solar and additional batteries.
Yes, a 300Ah lithium battery is enough for many travel trailers running daily essentials like a 12V fridge, LED lights, water pump, roof vent fan, phone chargers, and a small inverter. The Vatrer 300Ah lithium battery gives you 3840Wh, which is a strong single-battery setup for weekend camping or short off-grid stays. If you run high-draw appliances like a microwave, induction cooktop, or air conditioner often, adding solar or expanding the battery bank is recommended.
Because this battery has a 200A BMS, the practical continuous output is about 2560W at 12.8V. A 2000W pure sine wave inverter is usually a good match for RV use, covering devices like a coffee maker, laptop charger, TV, small microwave, or portable fridge. For a 3000W inverter, you need to check surge demand carefully because heavy loads may exceed the battery’s continuous discharge limit.
Only if your RV converter supports LiFePO4 charging voltage. This Vatrer 12V 300Ah LiFePO4 battery charges best with a 14.6V LiFePO4 charger, and a 70A charger can recharge it in about 4.5 hours from low power. If your Class A, Class C, or fifth-wheel RV still uses an older lead-acid converter, upgrading to a lithium-compatible charger or DC-DC charger is safer and more efficient.
For this 3840Wh battery, a 400W solar array can recover useful daily power for light RV use, while 600W–800W is better for faster charging during boondocking. You also need a properly sized MPPT solar charge controller that supports LiFePO4 charging. For example, a travel trailer with a roof fridge vent fan, 12V compressor fridge, and lights will benefit more from 600W+ solar if you camp off-grid for multiple days.
Yes. This Vatrer 300Ah lithium battery supports up to 4 batteries in series or 4 batteries in parallel, allowing a maximum 4P4S system up to 61.44kWh. That gives you flexibility for larger RV solar systems, off-grid cabins, fishing cabins, or home backup setups. Always use batteries of the same model, same capacity, same age, and similar state of charge before connecting them.
Yes, it can work well for many 12V marine power setups, especially for fish finders, lights, pumps, onboard electronics, and small trolling motor systems. At 55.23 lbs, it is much easier to handle than heavy lead-acid batteries in a bass boat, jon boat, or small fishing boat storage compartment. Before using it with a trolling motor, confirm that the motor voltage is 12V and the current draw stays within the battery’s 200A continuous discharge rating.
Yes, especially when the battery is installed in a hard-to-reach RV battery bay, boat compartment, or off-grid storage box. This 300Ah lithium battery with Bluetooth lets you check voltage, temperature, charge status, and battery health through the Vatrer app download without opening the compartment. That makes it easier to catch charging issues, cold-weather limits, or unexpected power drain before your fridge, lights, or inverter suddenly stop working.
