The BLUETTI B4810 is a 48 V LiFePO₄ battery with a 5.12 kWh capacity, designed for larger and more demanding power systems. It is ideal for motorhomes, camper vans, boats, off-grid setups and other applications where a standard 12 V battery is no longer enough. The B4810 is commonly used as the main battery alongside systems such as the BLUETTI RV5 Power Hub.

The B4810 is designed for powering more demanding appliances beyond basic 12 V systems. With 5.12 kWh of storage and around 5 kW continuous output, it can support loads such as air conditioning, induction cooking, boilers and power tools. Its 48 V design helps reduce cable size, lower current draw and improve efficiency, while the modular setup allows you to expand the system up to over 120 kWh as your power needs grow.

The B4810 uses long-life LiFePO₄ cells designed for thousands of charge cycles while maintaining strong performance over time. It supports a recommended charging current of around 50 A, with capacity for up to 100 A in suitable installations, allowing safe and efficient charging at higher power levels.

The B4810 features a durable IP65-rated housing with a flame-retardant UL5VA enclosure, making it suitable for vehicles, technical compartments and off-grid installations. It also includes a built-in self-heating function, allowing safe charging in colder temperatures by warming the battery before charging begins.

The B4810 performs best as part of a complete 48 V energy setup, working alongside the BLUETTI RV5 Power Hub. The battery stores energy as 48 V DC, while the RV5 manages charging and power distribution from sources such as shore power, solar panels and the vehicle alternator. It then converts the stored power into 230 V AC and 12/24 V DC, allowing appliances like air conditioning, fridges, lighting and pumps to run from one centralised system.

In addition to the 48 V power connection, the B4810 communicates with the RV5 via a CAN data connection. Its built-in BMS continuously shares battery status, power flow and safety limits, allowing the RV5 to optimise charging and discharging automatically. Through Bluetooth and the app, you can also monitor battery level, voltage and temperature in real time for easy system management.

Off-grid living, RV journeys, home backup, or life on the water, BLUETTI batteries provide reliable power to keep you connected, your devices charged, and everything running smoothly.

With 5,000 W of continuous power, the RV5 lets you run your A/C, microwave, coffee maker, and more all at once, just like at home. Powered by B4810 LiFePO₄ batteries, it gives you over 6,000 charge cycles for years of reliable energy. Even in the cold, the self-heating feature keeps things running smoothly. At only 7 W of standby power, each charge goes further. The RV5 lets you live fully, with peace of mind, and enjoy every moment of your journey without worrying about power.

Adventure doesn't stop for charging, and now you don't have to either. The RV5 keeps you powered with fast, versatile charging options. Recharge quickly with up to 5,000 W of shore power at the campsite, capture up to 1,800 W from the sun while boondocking, or harness up to 1,200 W from your vehicle's alternator while on the road. Focus on the journey, not the charge.
