B1232 LiFePO₄ Battery | 12.8 V, 314 Ah

BLUETTI B1232 LiFePO₄ Battery | 12.8 V, 314 Ah

The BLUETTI B1232 is a 12.8V lithium iron phosphate battery built for off-grid sheds, mid to large caravans, and 12V marine setups that need serious reserve capacity. It pairs a 314Ah cell bank with built-in self-heating, a multi-stage BMS and Bluetooth app monitoring, so you get lead-acid-style voltage with none of the weight or maintenance. It is designed to sit on its own or link into a larger bank as your property or rig's power needs grow.

High-Capacity, Long-Life Power: Capacity is 4,019.2 Wh at 12.8V, 314Ah , and the cell is rated to 6,000 cycles at 70% capacity . In practical terms that is a battery you can cycle hard season after season, in a shed, caravan or boat, without the capacity fade you'd expect from a lead-acid bank of the same size.

Self-Heating for Cold Paddock Mornings: BLUETTI fits a self-heating film inside the case that switches on automatically in low temperatures to bring the cells back to an ideal working range before charging begins. The cells are rated to 6,000 cycles at 70% capacity, and each pack includes a built-in self-heating film that activates below 0°C and maintains cell temperature near 25°C to allow charging in cold conditions. That means a cold start on the farm or at the boat ramp doesn't knock the battery offline waiting for it to warm up on its own.

Fast, Flexible Charging: Charge current is 70A recommended with 140A max, discharge current is 140A max, and peak discharge runs to 310A for 8 seconds . That headroom covers a solar array, DC-DC charger and AC charger all working at once, plus the short, hard pulls that a winch, compressor fridge or bilge pump can demand.

Multi-Layer Protection and App Monitoring: The battery's BMS watches over-current, over-voltage, short-circuit and cell temperature at all times, and cell temperature protection cuts charging below -1°C or above 61°C, and discharging below -21°C or above 61°C . You can connect multiple units to form a larger bank — up to 24 B4810 units or 96 B1210 units for 122.88 kWh, or up to 96 B1232 units for a total of 385.8 kWh , and track state of charge, voltage and temperature from the BLUETTI app over Bluetooth at any point in that system.

Built for Rough Conditions: The unit carries an IP65 ingress rating , which suits a boat locker, trailer tub or an open-sided shed where dust and the odd splash are part of the job. It is rated for up to 4S (48V) in series and up to 24P in parallel , so you can start with a single 12V pack and build out as your system grows.
