Combined with smart BMS protection, the system maintains safe operation while supporting consistent, long-lasting performance for RV and off-grid applications.
Built with EVE Grade A Cells and EGBATT In-House BMS for Matched Safety and Performance
Our 5kWh 12.8V 400Ah RV lithium battery is built with brand-new EVE Grade A LiFePO4 cells, selected for their proven consistency, low internal resistance, and long cycle stability. By using only new, matched cells, the battery delivers reliable capacity, stable voltage output, and predictable performance throughout its service life—critical factors for RV and mobile power systems.
To ensure optimal compatibility, this battery is paired with an EGBATT in-house developed BMS, engineered specifically around the electrical characteristics of the 400Ah cell configuration. The BMS continuously manages charge and discharge behavior, balances cells precisely, and responds accurately to temperature and current changes, allowing the battery to operate within safe and efficient parameters under real driving and load conditions.
By combining EVE Grade A cells with a purpose-built BMS, the system achieves a balanced focus on safety, performance, and longevity rather than theoretical specifications alone. This design approach reduces system stress, improves overall efficiency, and provides a dependable power solution suitable for long-term RV use, off-grid travel, and demanding energy applications.
5kWh 12V 400Ah Lithium RV Battery Powers Your RV Efficiently
the 5kWh 12V 400Ah lithium RV battery can support both high-power equipment and everyday onboard devices at the same time. Under a typical combined load—such as a parking air conditioner, refrigerator, laptop, lighting, and small appliances—the system can deliver power for about 4 hours of continuous use. This makes it well suited for short periods of concentrated high-load demand. In real RV living conditions where devices cycle on and off rather than running continuously, the actual usable time is usually longer.
If you exclude the high-power parking air conditioner (around 1000W) and operate only daily essentials such as the refrigerator, laptop, lighting, and small electronics (about 290W total), the RV 5kWh lithium battery can provide approximately 17+ hours of runtime (5000Wh ÷ 290W). This usage pattern better reflects overnight and routine living power needs.
For this reason, 5kWh-class lithium battery systems are widely considered a practical capacity level for RV and light off-grid setups—they can handle peak loads when needed while still delivering long operating duration under normal daily consumption.
Ideal for Replacing Bulky AGM Systems
- This 5KWh 12.8V 400Ah lithium RV battery combines reliable performance with a 10-year lifespan, three times longer than standard AGM batteries, which typically last only 3 years.
- One unit 400Ah 12V RV lithium battery can replace up to nine 12V 100Ah AGM batteries, freeing over 70% of space in your RV, boat, or off-grid setup.
- Downsizing your battery bank without compromising energy capacity not only simplifies installation but also reduces weight and improves system efficiency.
- Make the smart upgrade to a compact, long-lasting lithium solution and leave bulky AGM batteries behind.
Smart Bluetooth 5.0 App Monitoring
With built-in Bluetooth 5.0, the RV 12v 400ah LiFePO4 battery delivers faster, more stable, and lower-power wireless communication compared with older Bluetooth versions. It ensures a reliable connection between the battery and your smartphone, even in complex RV or off-grid environments.
The system supports automatic connection, so once paired for the first time, the battery reconnects to your mobile App instantly whenever you are within range — no repeated setup required. This makes daily use simple and seamless.
Through the smart mobile App, users can monitor and manage the battery in real time, including:
- Real-time State of Charge (SOC)
- Voltage and current data
- Charge / discharge status
- Remaining capacity and runtime
- Temperature and protection status
- Historical performance data
This smart control and monitoring system helps users prevent over-discharge, optimize charging behavior, and extend battery lifespan. It is especially useful for RV, marine, solar, and backup power systems where visibility and remote monitoring are critical.

Frequently Asked Questions(FAQ)
Q1: What maintenance is required for this 12V 400Ah LiFePO4 RV battery?
LiFePO4 RV batteries require much less maintenance than lead-acid batteries, but proper use and simple care will help extend service life and reduce potential issues:
- Avoid long-term overcharging or deep discharging
- Use a dedicated LiFePO4-compatible charger — do not use old lead-acid chargers
- If stored unused for a long period, recharge every 3–4 months
Q2: What are the common ways to charge RV batteries?
Most RV users have at least three — and sometimes four — ways to charge their battery bank. Experienced RV owners understand these options and can choose the most suitable charging method for different situations.
The four most common RV battery charging methods are:
- Shore power (grid connection)
- Generator
- Solar panels
- Alternator charging while driving
Q3: What is your factory price? Does it include shipping?
Please provide your correct email address and submit an inquiry. Our sales team will contact you by email and provide a quotation based on your required quantity.
Our factory price does not include shipping costs. Freight charges are calculated separately based on the order quantity and the specific delivery address, whether by sea or by air door-to-door
Q4: Can a battery store AC power?
No. RV batteries store DC (direct current) power, not AC power. DC power can be converted into AC power through an inverter to run AC appliances.
Q5: What is the factory lead time?
The typical production lead time is 7–15 working days, depending on the order quantity.
Q6: What does the 10-year warranty include?
The warranty covers defects in materials and workmanship under normal operating conditions. Support may include repair, replacement, or technical assistance according to the warranty terms.

EGbatt offers dealer customers a 10-year warranty and technical service for its energy storage battery products.
DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.
SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.
C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.
The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.
kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.
EGbatt home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.
This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.
The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.
Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.
No. EGbatt focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
