The 12V 280Ah LiFePO4 Bluetooth Battery combines high energy density, 4,000+ cycle lifespan, and real-time Bluetooth monitoring. Its LiFePO4 chemistry ensures thermal stability and safety, while the 280Ah capacity delivers 3,584Wh for extended off-grid applications. Bluetooth connectivity enables voltage/temperature tracking via smartphone apps, distinguishing it from traditional lead-acid batteries.
How to Prevent Lithium-Ion Battery Fires and Explosions
How Does the 280Ah Capacity Benefit Energy Systems?
With 3,584Wh storage capacity, this battery powers RV refrigerators for 5-7 days continuously or runs 500W solar systems for 7+ hours. Its 1C discharge rate (280A peak) supports high-demand appliances like inverters, outperforming AGM batteries that typically degrade at 50% depth of discharge compared to LiFePO4’s 80-100% usable capacity.
For marine applications, the 280Ah capacity enables extended navigation system operation without requiring frequent shore power connections. When paired with a 3000W inverter, it can power microwave ovens (1500W) for 2.3 hours continuously or LED lighting systems (100W) for 35+ hours. The flat discharge curve maintains 13.2V-12.8V through 90% of capacity, unlike lead-acid batteries that experience voltage sag below 50% state of charge.

What Bluetooth Features Enhance User Experience?
The integrated BMS with Bluetooth 5.0 transmits real-time data including cell voltages (±0.01V accuracy), temperature (-20°C to 60°C range), and state of charge (SOC) with 2% precision. Users can configure low-voltage disconnect (8V-12.8V adjustable) and receive push notifications for abnormal conditions through dedicated iOS/Android apps like Sinowealth or JK BMS.
Advanced Bluetooth features include historical data logging with 30-day cycle records and capacity fade tracking through Coulomb counting algorithms. The app interface displays individual cell resistance measurements, enabling early detection of underperforming cells. Users can schedule automated system reports via email and integrate with smart home platforms using JSON API outputs. Firmware updates are delivered over-the-air, with version control tracking to maintain compatibility across battery banks.
Which Safety Mechanisms Prevent Thermal Runaway?
- CID (Current Interrupt Device) for overcurrent (＞300A)
- PTC resettable fuses per cell
- Gas venting valves at 25-30psi
- BMS-controlled temperature cutoff at 65°C±3°C
- Cell balancing with ±20mV tolerance
Can This Battery Integrate With Solar Systems?
Yes, it accepts 14.2V-14.6V solar charging via MPPT controllers with 0.2C-0.5C rates (56A-140A). The built-in self-consumption mode prioritizes solar input over grid power, reducing energy costs by 30-40% in hybrid setups. Compatibility with Victron Energy and Renogy systems enables seamless integration through CAN bus communication protocols.
| Solar Array Size | Charging Time (0-100%) | Efficiency |
|---|---|---|
| 400W | 9.5 hours | 92% |
| 800W | 4.8 hours | 94% |
| 1200W | 3.2 hours | 95% |
Three-stage solar charging optimization automatically adjusts absorption voltage based on temperature readings, compensating for voltage drop in long cable runs. The system supports PV array voltages up to 150VDC through compatible charge controllers, making it suitable for both 12V and 24V solar configurations.

- Terminal options: M8 bolts or GB/T lugs
- Low-temperature charging modules (-30°C operation)
How Does Recycling Compare to Lead-Acid Batteries?
LiFePO4 batteries contain non-toxic iron-phosphate cathodes, achieving 96% recyclability vs. lead-acid’s 99%. However, their 8-10 year lifespan reduces replacement frequency by 300%. Specialized recyclers like Redwood Materials recover 95% of lithium through hydrometallurgical processes, though current recycling costs average $4-6/kg compared to $1-2/kg for lead.
“The 280Ah Bluetooth-enabled LiFePO4 represents a paradigm shift in mobile energy. We’re seeing 40% adoption growth annually in marine/RV markets. The real innovation isn’t just capacity – it’s the diagnostic granularity. Users can now predict cell aging patterns through voltage delta analysis in Bluetooth apps, potentially extending pack life by 18-24 months through proactive maintenance.”
