The Bluetti B4810 is a 51.2V, 100Ah (5,120Wh) LiFePO4 battery for 48V RV, marine and off-grid systems, with 100A continuous discharge and self-heating for cold weather. It's the house battery for Bluetti's RV5 system and scales to about 122kWh with 24 units in parallel.

Real-world numbers: rated 5,120Wh, about 4,352Wh usable (rated Wh × 0.85). Through an inverter such as the RV5:

Load Runtime (RPC estimate)
Full-size refrigerator (60W average) about 72 hrs
12V compressor fridge (50W average) about 87 hrs
Wi-Fi router and modem (20W) about 217 hrs
Laptop and monitor (100W) about 43 hrs
Window AC, 5,000 BTU (500W running) about 8 hrs

Size it for your own setup: pick your appliances and days off-grid in the RPC Power Calculator, and it shows the in-stock stations and kits that fit.

It's rated for 6,000+ cycles to 80% capacity, and up to 24 units can run in parallel for about 122kWh. It pairs with Bluetti's RV5 power hub, Epad display and Epanel distribution panel in Bluetti's RVSolar system, and the Bluetti app provides monitoring.

Good to know: this is a fixed-install battery. Wire it to a 48V system with appropriately rated cable, fusing and a compatible charger or inverter; we recommend a qualified installer.

Best for: 48V RV and van electrical systems • Marine house banks • Off-grid cabins

Not the best fit if: you want a battery that plugs into a portable power station. The B4810 is a hardwired 48V battery. For Apex 300 expansion, look at the B300K or B500K.

Works with: RV5 Power Hub • Epanel smart distribution panel • Epad control screen • PV100FX flexible solar panels • Bluetti B4810 battery connection cables and RV5 battery wiring pack

Frequently Asked Questions

How long will one B4810 run an RV?
About 8 hours at a 500W load, or about 72 hours for a fridge averaging 60W, through an inverter like the RV5.

How many can I connect?
Up to 24 in parallel, for about 122kWh, per Bluetti.

Can it charge in freezing weather?
Yes. It self-heats in cold weather before charging.
