The 36V 100Ah OBM LiFePO4 Battery combines Bluetooth monitoring, low-temperature protection, and a 100A BMS for reliable deep-cycle performance. With 3,000-5,000 cycles at 80% DOD, it outperforms lead-acid batteries in energy density and lifespan. Its rugged design supports solar systems, marine applications, and off-grid power with real-time diagnostics through a dedicated mobile app.

How Does the Built-In 100A BMS Enhance Battery Performance?
The integrated 100A Battery Management System prevents overcharge, over-discharge, and short circuits while balancing cells. It enables continuous 100A discharge current with 200A surge capacity, making it suitable for high-power applications like electric vehicles. The BMS maintains optimal cell voltages (±0.05V variance) and operates in -20°C to 60°C environments.
The advanced BMS employs dynamic load balancing across all 12 prismatic cells, automatically redistributing energy during charge/discharge cycles. This precision monitoring extends cell lifespan by preventing voltage drift – a common failure point in multi-cell batteries. Field tests show the system maintains 98.6% energy efficiency even after 1,000 cycles, compared to 85% efficiency in standard BMS configurations. For industrial users, the 100A continuous rating allows simultaneous operation of multiple high-drain devices without voltage sag.

What Advantages Does Bluetooth Connectivity Offer Users?
The OBM Bluetooth module provides real-time monitoring of voltage (36V nominal), current flow, remaining capacity (Ah), and cell temperatures. Users receive push notifications for abnormal conditions through the dedicated app, which stores 12 months of historical data. The wireless interface eliminates manual checks and enables remote configuration of protection parameters.

How Effective Is the Low-Temperature Protection Feature?
The battery’s self-heating system activates at 0°C, maintaining chemical stability down to -20°C charging and -30°C discharging. This prevents lithium plating damage, with heating elements consuming <5% total capacity in extreme cold. Thermal sensors automatically adjust charge rates (0.2C max at -20°C) to preserve cycle life.
What Applications Benefit Most From This Battery Design?
Solar energy storage (compatible with 48V systems via series connection), marine trolling motors (8-10 hour runtime at 50A draw), and off-grid cabins. Industrial uses include floor cleaning machines (6-8 hour operation) and telecom backup systems. The IP65 enclosure withstands vibration (5-500Hz, 5G max) and 95% humidity environments.
Marine applications particularly benefit from the battery’s anti-corrosion terminals and saltwater-resistant casing. When powering a 55lb thrust trolling motor, users achieve 9.2 hours of continuous operation at medium speed – 40% longer runtime than equivalent AGM batteries. Solar installations see 22% faster ROI due to the battery’s 98% round-trip efficiency versus 80-85% in lead-acid systems. For off-grid homes, the built-in load terminals directly support 3,000W inverters without requiring additional bus bars.
“This battery represents a paradigm shift in mobile power solutions. The combination of 100A continuous discharge with active thermal management addresses the critical pain points in cold climate deployments. The Bluetooth diagnostics alone can reduce maintenance costs by 40% in commercial applications.” – Renewable Energy Systems Engineer with 15 years field experience
FAQs
- What’s the expected lifespan under daily cycling?
- 7-10 years with daily 80% DOD cycles, maintaining ≥80% capacity through 3,500 cycles. Calendar life extends beyond 12 years with proper storage.
- Can multiple units be connected in series/parallel?
- Series connection up to 48V (4 units) supported through BMS communication ports. Parallel configurations require external balancing modules.
- How does cold weather affect charging efficiency?
- At -20°C, charging efficiency maintains 92% versus 45% in standard LiFePO4 batteries, with heating system adding 18 minutes to full charge time.
