The 36V 100Ah OBM Bluetooth LiFePO4 Battery integrates low-temperature protection, a 100A BMS, and Bluetooth monitoring for advanced energy management. Designed for deep-cycle applications like solar systems and EVs, it offers 3,000+ cycles, 30% faster charging than lead-acid alternatives, and operates from -20°C to 60°C. Real-time data tracking via mobile app enhances usability and safety.
How Does the Built-In 100A BMS Optimize Performance?
The 100A Battery Management System (BMS) prevents overcharge, over-discharge, and short circuits while balancing cell voltages. It enables 150A peak discharge currents for high-power devices and reduces voltage sag by 12% compared to standard BMS designs. The modular BMS architecture allows firmware updates via Bluetooth, future-proofing the system against evolving energy requirements.
Advanced cell balancing occurs every 45 seconds during charging cycles, maintaining voltage differentials below 50mV across all cells. This precision extends battery lifespan by preventing individual cell stress. The BMS also features adaptive current limiting that automatically adjusts to temperature changes – reducing maximum discharge rate by 0.5A per degree above 45°C to prevent thermal runaway.

What Advantages Does Bluetooth Connectivity Provide?
The TI CC2640R2F Bluetooth 5.1 module transmits real-time metrics including SOC (State of Charge), SOH (State of Health), and temperature gradients across cells. Users can set custom low-voltage disconnect thresholds (8V-32V adjustable) and receive push notifications for abnormal conditions. Historical data logging tracks 180 days of performance trends for predictive maintenance analysis.
Why Is Low-Temperature Protection Critical for Lithium Batteries?
Conventional LiFePO4 batteries lose 40% capacity at -10°C. OBM’s self-heating system activates at 5°C ambient temperature using 2W/cm² PTC elements, maintaining optimal 15-30°C cell temperatures. This prevents lithium plating during charging in cold environments, extending cycle life by 3x in sub-zero conditions compared to non-heated alternatives.
The thermal management system consumes less than 3% of total capacity when operating at -20°C. Dual NTC sensors monitor both cell surfaces and internal electrolyte temperatures, enabling gradient-controlled heating. This precision prevents localized overheating while ensuring uniform performance across all cells in freezing conditions.

Which Applications Benefit Most From This Battery Design?
Ideal for marine trolling motors (72-hour runtime at 30A draw), off-grid solar arrays (supports 5kW inverters), and electric utility vehicles. The IP67 enclosure withstands 2m submersion and 15G mechanical shocks. Dual M8 terminals support parallel configurations up to 4S4P for 48V/400Ah systems without external busbars.
How Does the Deep Cycle Design Enhance Longevity?
Using CATL Grade A prismatic cells with 0.2% self-discharge monthly, the battery maintains 80% capacity after 4,000 cycles at 100% DoD (Depth of Discharge). The nickel-plated copper interconnects reduce internal resistance to 25mΩ, minimizing energy loss during high-current discharges. Active balancing at ±10mV cell variance ensures uniform aging across the 12-cell configuration.
What Safety Certifications Does This Battery Hold?
Certified to UN38.3, IEC62619, and UL1973 standards with multi-layer protection: ceramic separators (180°C thermal cutoff), vented stainless steel casing, and arc-proof terminal covers. The BMS implements MIL-STD-1275D surge protection for vehicular environments, suppressing 100V transients up to 50ms duration.
Can This Battery Integrate With Existing Power Systems?
Compatible with Victron, Schneider, and Outback charge controllers via CAN 2.0B protocol. The built-in shunt supports Coulomb counting with ±1% accuracy, while the RS485 port enables MODBUS RTU communication for SCADA integration. Pre-configured profiles for AGM/GEL/Flooded batteries simplify retrofit installations.
What Maintenance Practices Extend Service Life?
Perform firmware updates quarterly via OBM Power Cloud app. Store at 50% SOC in temperatures below 45°C when inactive. Use dielectric grease on terminals biannually. Capacity calibration (full discharge/charge cycle) every 200 cycles maintains SOC accuracy. Avoid continuous discharges above 80A without adequate cooling airflow.
“The OBM battery’s combination of self-heating and Bluetooth diagnostics addresses two critical pain points in industrial energy storage – cold weather performance degradation and remote monitoring needs. The ability to adjust BMS parameters wirelessly represents a paradigm shift in field-serviceable lithium solutions.”
