320Ah MINI · BLUETOOTH · DUAL-MODE SELF-HEATING
More RV Energy. A Compact Fit. Ready for Cold-Weather Charging.
The TUORDE 12V 320Ah Mini Smart Self-Heating LiFePO4 RV Battery combines a 4.096kWh nominal energy bank with a 200A BMS and Bluetooth-controlled heating. Its compact enclosure gives RV builders a practical starting point for high-capacity house-power installations, while dual heating modes help prepare the cells for charging in freezing conditions.
For RV manufacturers, battery distributors, vehicle upfitters and private-label brands.
4.096kWh
Nominal energy for daily house loads.
Dual-Mode Heating
Select a heat source around your charging access.
Bluetooth Monitoring
Check battery status before planning your next stop.
Two Heating Modes for Different RV Charging Situations
Connected to Shore Power or a Charger
External-power mode uses the charger to warm the battery. This keeps stored energy available for your RV loads while the cells reach the charging threshold.
Preparing Before the Next Charge
Battery-powered preheating can be selected through the compatible Bluetooth app when SOC is above 20%. It uses stored energy, so include heating demand in your off-grid reserve plan.
Low ambient temperature does not mean frozen cells can accept charge. The BMS blocks cell charging below 0°C and resumes at 5°C. Use the specified charger and follow the heating instructions supplied with the battery.

Energy is nominal, not measured usable output. Heating times depend on the stated charge current and starting temperature. Cycle results depend on operating conditions and the capacity-retention criterion; request the applicable test report. Final OEM configuration, mechanical drawing and compliance-document scope form part of the order specification.
Plan Around Both Energy and Discharge Current
320Ah supports energy planning; the BMS current limit determines the power path. Select an inverter from the battery's continuous DC rating after accounting for conversion losses, operating voltage and appliance startup demand. A short peak rating is not permission to run a larger load continuously.
Use a compatible LiFePO4 charger, solar controller or alternator-fed DC-DC charger. A generator must feed an appropriate battery charger. Disable lead-acid equalization and desulfation modes, and check cable ampacity, fuse selection and charger activation support.
House power only: this deep-cycle battery is not an engine-starting battery. IP65 also does not permit immersion or remove the need for protected electrical connections.
Bluetooth Visibility, with an OEM Path for Advanced Monitoring
Use Bluetooth 5.0 with the matched app to review battery status and manage heating. Confirm app access and setup with the supplied configuration before installing the battery in an enclosed compartment.
For branded battery programs, discuss runtime prediction, abnormal drain alerts, battery health insights and guided troubleshooting separately. CAN, RS485, gateways and advanced software functions require the relevant hardware, protocol and firmware; they are not implied by this model's Bluetooth specification. Guided diagnostics do not physically repair battery cells.

Check the Complete Installation Envelope
Compare the enclosure drawing with your battery tray, hold-down system and access opening. Allow additional space for terminal covers, cable bends and maintenance. Do not identify this Mini enclosure as a Group 24, Group 27, Group 31 or DIN replacement from capacity alone.
Expansion uses matched batteries with the same capacity, BMS and brand. Follow the approved balancing and connection procedure; do not combine different-age, mixed-capacity or incompatible batteries. A fully populated 4S4P bank has calculated nominal ratings of 51.2V, 1,280Ah and 65.536kWh; installation design and protection must be reviewed for the complete bank.
An OEM Battery Brief That Starts with the RV Installation
Send your compartment drawing, appliance list, charging sources, winter operating requirements, estimated quantity and destination market. TUORDE can review branding, labels, packaging and monitoring requirements around the selected battery platform.
Request a model-specific datasheet, installation instructions and applicable compliance documents with your quotation. Sample terms, warranty coverage and production lead time are agreed for the TUORDE order rather than copied from another brand's retail policy.

320Ah Mini Self-Heating Battery FAQ
Can this battery charge in freezing weather?
The heating system prepares the cells before charging. Follow the operating range, heating-current requirement and temperature thresholds in the specification table; do not bypass low-temperature protection.
Can heating operate without a connected charger?
The battery-powered mode can preheat using stored energy when its SOC condition is met. Select the mode through the compatible app and retain enough energy for the planned house loads.
Does the peak current make it suitable for engine starting?
No. This is an energy-storage battery for deep-cycle house loads. Its brief surge allowance does not establish cranking performance or vehicle-starting compatibility.
How should I estimate RV runtime?
Start with nominal energy, then allow for the approved discharge window, inverter losses, heating, temperature and battery condition. Divide the resulting usable-energy estimate by average load power. Request an application review instead of treating nominal capacity as a runtime guarantee.
Are CAN, RS485 and AI diagnostics standard on this version?
Bluetooth monitoring and heating control are part of the selected configuration. Additional communication interfaces and advanced analysis functions require a separate OEM configuration review.
Can TUORDE supply this battery under my brand?
Discuss your labels, packaging, app requirements, target market and purchase volume with TUORDE. The quotation should identify the exact battery configuration and documents supplied.
