Power of Vatrer 12V 300Ah Lithium Battery
If you're looking for a reliable energy solution for your RV, solar setup, or home storage, the Vatrer 12V 300Ah lithium battery with a 200A BMS is a practical option.
Built with LiFePO4 technology, it offers over 5,000 cycles and a lifespan exceeding 10 years, ensuring long-term value without frequent replacements. Whether you're powering appliances on a RV camping trip or storing energy from solar panels.
High Capacity and Powerful Output
With a 300Ah capacity and 12.8V nominal voltage, this battery packs 3840Wh of usable energy, ideal for applications like RV air conditioners or solar pumps. It supports a maximum continuous discharge of 200A, giving you the flexibility to run larger devices. At just 55.23 lbs, it's lighter than many traditional options, making it easier to install in tight spaces like an RV or boat.
Built-in 200A BMS for Enhanced Safety
12V 300Ah built-in 200A battery management system (BMS), designed to keep your power source secure. Using upgraded Grade A cells, it protects against overcharge, over-discharge, overcurrent, short circuits, and extreme temperatures. This system also features auto-cell balancing, ensuring each cell works in harmony for optimal performance. Whether you're using it in a hot climate or a demanding setup, the 200A BMS provides real-time monitoring to prevent potential issues, making it a reliable choice for your energy needs.
Low-Temp Cut-Off for Reliable Protection
Its low-temp protection feature adds an extra layer of reliability, intelligently cutting off charging below 32°F (0°C) and discharging below -4°F (-20°C) to safeguard the battery. It also supports charge voltage adjustments and resumes charging at 41°F (5°C), ensuring safe operation during cold weather. This is especially useful for winter RV trips or off-grid homes, keeping your 12V 300Ah battery protected and ready to perform when temperatures drop.
Compact Size Compared to AGM Batteries
With dimensions of 15.16 x 7.56 x 9.76 inches(Overall dimensions include the housing cover and protruding parts:15.1*7.6*9.8 inch), this battery’s compact design stands out, especially when compared to traditional options. It can replace three 300Ah AGM batteries, significantly reducing the space required and simplifying installation with M8 terminal bolts for secure, straightforward connections. Weighing just 55.23 lbs—far less than the 165.69 lbs of equivalent lead-acid batteries—it’s easier to handle and install in tight spaces like RVs or boats, offering a practical upgrade for your energy setup.
Flexible Expansion for Larger Systems
The Vatrer 12V 300Ah lithium battery offers versatile expansion options, allowing you to connect up to four batteries in series or 4 in parallel. This setup can scale your energy storage to a maximum of 61.44kWh with a 4P4S configuration, making it a great fit for larger systems like off-grid cabins or extensive RV setups. The ability to customize your power capacity ensures you can adapt the battery to meet growing energy demands.
Versatile Charging Options for Convenience
The Vatrer 12V 300Ah lithium battery offers three practical charging methods to suit different needs. You can use a LiFePO4 charger (14.6V 70A) to fully charge it in about 4.5 hours, ideal for quick top-ups at home. For solar setups, a solar panel with an MPPT controller (850W) can recharge it in about 4.5 hours per day, making it a great match for off-grid living. Additionally, pairing a generator with a 40A DC-to-DC charger gets the job done in around 7.5 hours, offering flexibility for camping or remote locations. These options ensure you can keep your battery ready no matter where you are.
Perfect for Your Energy Needs
This Vatrer 12V battery fits various scenarios. For off-grid living, it maximizes savings by storing solar energy efficiently. RV enthusiasts can go further with reliable power for longer trips, while campers can explore deeper with a portable energy source. At home, it provides longer energy storage for devices, supporting a fan (100W) for 38.4 hours, a refrigerator (300W) for 12.8 hours, a cooker (500W) for 7.5 hours, or an air conditioner (1500W) for 2.5 hours. So, it's a versatile option tailored to your lifestyle.

They have been great, so far. Well constructed and they definitely put out some power! When I purchased these, I was under the assumption they were blue tooth, but these are not. Not a deal breaker, I purchased a remote monitor for them instead, but it was an expense I wasn't planning on.
S
300 ah battery, great so far, charged up no problem, I load tested it heavily and it held up really well
N
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.

I DID NOT GET IT YEAH IN MEXICO. SO SOONEST I GET IT AND CONECTES LETYOU KNOW.
Yes, the low-temp cut-off feature ensures safe operation by stopping charging below 32°F and discharging below -4°F, with recovery at 41°F. This protection, combined with charge voltage adjustments, makes it suitable for cold climates like winter RV trips, though it’s wise to monitor usage during prolonged freezes to maintain optimal performance.
The built-in 200A BMS includes safeguards against improper connections, such as overcurrent and short-circuit protection. However, to avoid issues, follow the manual’s guidelines for series or parallel setups (up to 4P4S for 61.44kWh). If unsure, consult the Vatrer support team for assistance to ensure a safe and efficient expansion.
Without solar, you can fully charge the 12V 300Ah battery in about 4.5 hours using a LiFePO4 charger (14.6V 70A), or around 7.5 hours with a generator and a 40A DC-to-DC charger. These options provide flexibility for home or remote use, ensuring you can recharge conveniently based on your setup.
Yes, the IP65 waterproof rating protects against dust and water exposure, making it suitable for RV use in rainy conditions. However, avoid submerging it and ensure proper ventilation to maintain the battery management system BMS efficiency, especially in humid environments.
The 3% self-discharge rate means it can sit for a month with minimal loss, but for longer storage, keep it fully charged and store it in a cool, dry place. If it loses charge, use a compatible charger to recharge it. If issues persist, contact Vatrer support, as the 200A BMS may need a check for optimal performance.
No, this 12V 300Ah lithium battery is designed for energy storage, not engine starting. Its 200A continuous discharge are tailored for devices like refrigerators or air conditioners, not the high cranking power needed for car engines. Check the manual for alternative uses.
