LiTime 320 Ah LiFePO₄ Battery Announcement: Capacity, Compatibility, and Limits
Direct answer: LiTime sells a 12V 320Ah (12.8V nominal) lithium-iron-phosphate battery with a 200A BMS, Bluetooth monitoring, and a 5-year warranty.[1] The specification figures below come from the manufacturer's product page; NerdVolt has not independently tested the battery, and buyers should confirm the exact model's datasheet, warranty text, and compatibility list before purchasing.
Exact model identity and what was announced
The product page describes the LiTime 12V 320Ah Mini Bluetooth Lithium Battery for RV, off-grid, and marine use, with a separate self-heating variant also listed. This article records what the official page states as of August 15, 2026; it is an announcement record, not an independent product test.
Manufacturer-stated specifications
| Specification | Manufacturer statement | Verification status |
|---|---|---|
| Nominal voltage | 12.8V[1] | Manufacturer-stated; not independently measured |
| Rated capacity | 320Ah[1] | Manufacturer-stated; usable energy depends on discharge rate and cutoff |
| Energy | 4096Wh[1] | Manufacturer-stated |
| BMS | 200A continuous[1] | Manufacturer-stated |
| Max continuous output power | 2560W | Manufacturer-stated |
| Max continuous charge / discharge current | 200A / 200A[1] | Manufacturer-stated |
| Peak discharge current (1 second) | 1000A[1] | Manufacturer-stated |
| Charge method / voltage | CC/CV, 14.4V ± 0.2V[1] | Manufacturer-stated |
| Recommended charge current | 64A[1] | Manufacturer-stated |
| Low-temperature charging | Charge off below 0°C; recovery at 5°C[1] | Manufacturer-stated |
| Certifications | FCC, CE, RoHS, UN38.3; IEC 62619 compliance claimed | Certificates not independently reviewed here |
| Warranty | 5 years; 30-day price guarantee[1] | Warranty text not independently reviewed here |
| Expansion | Series to 4 batteries (51.2V), parallel to 4 (1280Ah), series-parallel to 16[1] | Manufacturer-stated; verify with the manual |
The table repeats manufacturer-stated values only. Capacity and current ratings in practice depend on temperature, connection resistance, BMS settings, and the exact load or charger.
Cycle-life claims and what they mean
The page states 4,000 cycles at 100% depth of discharge, 6,000 cycles at 80% DoD, and 15,000 cycles at 60% DoD.[1] Cycle counts are only meaningful with their test conditions — temperature, charge/discharge rate, and the capacity-retention threshold used to define end of life — which the product page does not fully specify. Treat these as marketing figures to be checked against the detailed datasheet, not as a guarantee of a service life in your exact use pattern.
Announced versus independently verified
Confirmed from the official page (August 15, 2026): the model identity, nominal voltage, rated capacity, energy figure, BMS rating, charge and discharge current figures, charge voltage, recommended charge current, low-temperature cutoff behavior, certification list as claimed, warranty term, and expansion configuration as listed above.
Not independently verified by NerdVolt: measured capacity on a test bench, real-world cycle life, BMS behavior under fault conditions, certification validity, warranty enforcement, and compatibility with any specific inverter, charger, or solar charge controller.
What buyers should check before purchasing
- Request the exact model's datasheet and user manual, and confirm the charge voltage (14.4V ± 0.2V) matches your charger's lithium profile.[1]
- Confirm the charge controller or inverter-charger can deliver the recommended 64A charge current and is configured for LFP voltage ranges.[1]
- Check low-temperature charging behavior: charging is stated to turn off below 0°C with recovery at 5°C — confirm how your system prevents charging in freezing conditions.[1]
- Review the warranty text (5-year term, exclusions) and the return/price-guarantee terms before purchase.
- If you plan series or parallel expansion, confirm the exact model allows it and follow the manual's connection and bus requirements.
- Compare the 200A BMS continuous rating against your inverter's surge and continuous demand; the battery is not a substitute for correctly sized conductors, fuses, and installation per code.[1]
