LiTime 36V 50Ah Trolling Motor Battery
The LiTime 36V 50Ah trolling motor battery is built with automotive-grade LiFePO4 cells and is designed for long life on the water. It supports up to 4 batteries in parallel to create a larger 36V system, enabling higher total capacity for extended trolling sessions. A 50A BMS provides safeguards against over-discharge and short circuits, while its Bluetooth 5.0 integration lets users monitor status, discharge control, and system checks remotely.
Key points include a claimed 4000+ cycle life and a service life up to 10 years, significantly outlasting traditional lead-acid options. The battery is suitable for trolling motors up to 120 pounds of thrust and is part of a broader ecosystem that includes ABYC and ASA endorsements, signaling a marine-grade design.
LOSSIGY 36V 100Ah Lithium Battery
The LOSSIGY 100Ah model emphasizes high capacity with a built-in 200A BMS and IP65 waterproof rating, making it well-suited for golf carts, trolling motors, and marine use. The system supports parallel connections to scale capacity and includes a robust safety feature set to protect against overcharging, overdischarging, overcurrent, and temperature extremes. Expect thousands of cycles, a lighter footprint compared to lead-acid, and strong peak current handling for demanding motor starts.
LiTime 36V 100Ah OBM Battery with Bluetooth
This LiTime OBM battery is ABYC-certified and optimized for electric outboard motors, supporting brands like Torqeedo, ePropulsion, Yamaha, and others. It offers a 500A surge capability and a 1.2C discharge rate, with an intelligent Bluetooth interface for real-time monitoring. The IP65 rating and a broad operating range (-20°C to 60°C) make it a strong choice for varied marine climates and weather conditions. The battery can deliver robust performance with fast response during startup and steady operation for ongoing trolling tasks.
LiTime 36V 100Ah OBM Battery (Second Model)
Another LiTime OBM option emphasizes low-temperature protection and a high-capacity design tailored for outboard use. It handles startup surges with a 500A/1s capability and supports a rapid 1.2C discharge for up to three minutes. An upgraded intelligent cut-off prevents charging below 0°C and discharging below -20°C, helping protect the battery in cold environments. Bluetooth 5.0 ensures ongoing visibility into voltage, SOC, and system health as part of a connected boating experience.
Mehrpow 36V 105Ah Battery
The Mehrpow 105Ah model combines a lightweight profile with a strong 200A intelligent BMS and an LCD display for real-time monitoring. IP65 sealing helps resist dust and water, while the 40-mile range on a typical golf cart use case demonstrates practical daily capability. It supports a peak current of up to 1000A, enabling confident handling of steep gradients and motor startup. The design aligns with modern marine and outdoor power needs, offering a balance of weight, range, and safety features.
Buying Guide
- Battery chemistry and cycle life: Most marine 36V batteries use LiFePO4 cells for long life and better thermal stability. Look for 4,000+ cycles and a service life of 8–15 years in ideal conditions.
- Battery Management System (BMS): A robust BMS protects against overcharge, overdischarge, short circuits, and temperature extremes. Higher continuous and peak discharge ratings support faster starts and better motor response.
- Temperature range and protection: Cold-weather protection and low-temperature cut-off help maintain performance in diverse climates. IP ratings (IP65) indicate water and dust resistance essential for boats.
- Monitoring and connectivity: Bluetooth or app-based monitoring enables real-time status, SOC, voltage, and health checks. Auto-recovery and smart discharge control reduce downtime and maintenance.
- Expansion capability: Parallel (not series) connections allow larger 36V systems by adding multiple packs. This is important for boats requiring more capacity for extended trolling sessions.
- Physical attributes: Weight, size, and mounting considerations matter for boat layouts and weight distribution. LiFePO4 cells are lighter than lead-acid for the same capacity, improving handling and efficiency.
- Brand and certifications: Look for ABYC and ASA alignment or certification, which signal adherence to marine industry safety and performance standards.
- Warranties and service: A strong warranty and accessible customer support help with installation, troubleshooting, and potential system upgrades.
