LiTime 36V 50Ah Marine Trolling Motor Lithium Bluetooth Battery

The LiTime 36V 50Ah Bluetooth Smart Marine Trolling Motor Battery is a compact, lightweight lithium power solution designed specifically for 36V trolling motors in the 100–120 lb thrust range. Built with EV-grade LiFePO4 cells, Smart Bluetooth monitoring, an advanced Battery Management System, and marine-ready protection, this battery is an excellent upgrade from a traditional three-battery lead-acid setup.

With approximately 1.92 kWh of usable energy in a single battery, the LiTime 36V 50Ah provides dependable power while greatly reducing onboard weight and the amount of battery space required.

Smart Bluetooth 5.0 Monitoring

Built-in Bluetooth 5.0 allows you to connect directly to the LiTime mobile app and monitor your battery in real time.

Through the app you can view:

• Battery State of Charge (SOC)
• Voltage
• Current
• Power
• Remaining capacity
• Charge and discharge status
• Battery temperature
• Cycle information
• Battery operating status

The app also allows you to control battery discharge and power the battery off remotely.

Designed for 36V Trolling Motors

This battery is designed for 100–120 lb thrust trolling motors, making it a great option for fishing boats, bass boats, pontoons, kayaks, and other marine applications requiring a dependable 36V power source.

Instead of carrying three separate 12V batteries to create a 36V bank, the LiTime provides the complete 36V system in a single compact battery.

Advanced Smart BMS Protection

LiTime equips the battery with an advanced Smart Battery Management System (BMS) providing more than 20 protections and warnings.

Protection features include:

• Over-voltage protection
• Low-voltage protection
• Over-current protection
• Short-circuit protection
• Overload protection
• High-temperature protection
• Low-temperature protection
• Low-temperature charging cutoff
• Automatic over-current recovery
• Pre-charging protection
• Moisture resistance
• Salt-spray resistance

These protections help provide reliable operation in demanding marine environments.

Low-Temperature Protection

The built-in low-temperature protection helps protect the LiFePO4 cells during cold-weather operation.

The battery automatically stops:

• Charging below 32°F / 0°C
• Discharging below -4°F / -20°C

This helps prevent cell damage and supports longer battery life.

High-Power LiFePO4 Performance

The EV-grade LiFePO4 cells provide excellent energy density, long cycle life, and consistent power output.

Power capability includes:

• Up to 50A continuous discharge
• Up to 60A discharge for approximately 30 minutes
• Up to 250A peak discharge for 1 second

This gives the battery the ability to handle demanding trolling motor loads while maintaining stable performance.

Long Service Life

LiTime rates the battery for 4,000+ deep cycles at 100% depth of discharge, with potential cycle life reaching significantly higher levels under lighter cycling conditions.

Expected battery service life can reach approximately 10 years, making LiFePO4 a major long-term upgrade compared with conventional lead-acid marine batteries.

Lightweight Alternative to Lead-Acid

At approximately 33.14 lb, this battery dramatically reduces the weight of a traditional 36V lead-acid battery bank.

According to LiTime, it is approximately:

• 65% lighter than three comparable 12V 50Ah lead-acid batteries
• Capable of delivering approximately 2.1× the energy
• Designed to provide substantially longer cycle life

The reduced weight can improve boat handling while freeing up valuable battery compartment space.

IP65 Marine Protection

The battery carries an IP65 protection rating, providing resistance to water and dust encountered in normal boating and fishing environments.

Combined with moisture-resistant and salt-spray-resistant construction, the battery is designed specifically with marine applications in mind.

Expandable Battery Capacity

Need additional runtime?

Multiple LiTime 36V 50Ah batteries can be connected in parallel, allowing the system to expand up to approximately:

38.4V 200Ah / 7.68 kWh

This makes it possible to increase available energy while maintaining a 36V-class system.
