Hot LiTime 12 Volt 100Ah TM Lithium Marine Trolling Motor Battery with Bluetooth

Normally, it's not recommended to use a battery designed for a trolling motor in an electric outboard motor since the surge discharge current might not be sufficient. Outboard motors often require higher power for acceleration and sustained operation, which can lead to higher surge currents that trolling motor batteries may not handle well.

If you’re planning to use an electric outboard motor, it’s best to invest in a battery specifically designed for such applications like LiTime Outboard Motor Batteries. These batteries are built to handle the high power requirements and ensure optimal performance and safety.

Read on Electric Outboad Motor VS Trolling Motor for more detailed information.

Use a 14.4V 10A LiFePO4 charger. For easier BMS recovery after deep discharge, a charger with activation support is recommended.

If the battery enters low-voltage protection, disconnect all loads first. Then connect a compatible LiFePO4 charger with activation function to wake and recharge the battery. Once charging resumes and the voltage returns to normal, reconnect the system. If the battery still cannot be activated, contact LiTime Support for assistance.

This 12V lithium battery, equipped with an integrated Bluetooth module, enables convenient monitoring of the battery status using your smartphone through the LiTime App.

Please charge the Bluetooth battery first after receiving it. This will ensure that the battery can be turned on and the Bluetooth connection is established.  

Our Bluetooth batteries are delivered in the off state, the virtual voltage of the battery terminal is 3V-5V, this is a normal phenomenon, just use the AC-DC lithium battery charger or MPPT solar charge controller to charge the battery and turn on the battery, it can be used normally.

If you intend to store the battery for an extended period without use, we recommend charging it to a SOC 50% and conducting maintenance every three months. These measures will help preserve its functionality and performance in the long run.

For versatile system configurations, you can connect multiple LiTime 12V 100Ah Trolling Motor Bluetooth LiFePO4 batteries.

You can expand your battery bank's voltage and capacity by connecting identical batteries:

• Series: Connect up to four batteries in series to create a higher voltage system (e.g., 24V, 36V, or 48V).
• Parallel: Connect up to four batteries in parallel to increase the total capacity (Ah) to 400Ah.
• Series-Parallel: Build a larger bank of up to 16 batteries in a 4S4P configuration (4 in series and 4 in parallel) for maximum power and capacity.

⚠️ Critical Connection Requirements

To ensure safety, performance, and longevity, all batteries in a connected bank must meet these conditions:

• Identical Model: Use the exact same battery model (e.g., LiTime 12V 100Ah TM Bluetooth) with the same capacity (Ah) and BMS rating (A).
• Same Brand: Never mix batteries from different brands. Each brand uses a unique Battery Management System (BMS) that is not compatible with others.
• Recent Purchase: The batteries should be purchased close together, ideally within one month, to ensure they are from the same manufacturing batch for balanced performance.
• Voltage Matched: Before connecting, ensure all batteries are fully charged and their voltages are balanced to within 0.1V of each other. This prevents large inrush currents that can damage the batteries.

No. LiTime Trolling Motor lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices. If you need the marine starting batteries, visit LiTime Marine Cranking Batteries to choose.

The answer depends entirely on your charging routine.

For many boaters, a standard charger is all that's needed. If you typically remove your battery from the boat to charge it indoors—in a garage, shed, or at home—a standard charger is a perfectly safe and cost-effective solution.

However, if you want the convenience of an onboard charging system, then a waterproof charger is essential. If you plan to permanently install the charger inside a boat compartment to plug into shore power at the dock, a waterproof model is necessary to protect against moisture, splashes, and humidity, ensuring both safety and the charger's longevity.

Here's a simple guide to help you decide:

• Choose a Standard Charger if: You always charge your battery off the boat (e.g., at home or in the garage).
• Upgrade to a Waterproof Charger if: You plan to permanently install the charger on your boat.

Some of our packages include a standard charger to provide the best value for the most common use cases. If an onboard setup fits your needs, we highly recommend purchasing one of our IP65 Waterproof Marine Chargers for 12V Batteries.

A LiTime 12V 100Ah battery provides about 1,280Wh of usable energy.At low speed (20–30A draw), a trolling motor can run 4–6 hours. At medium speed (40–50A), expect 2–3 hours, while full throttle may reduce runtime to 1–1.5 hours.Learn more about how Long Will 4 Parallel 12V 100Ah Lithium Batteries Last?
