Designed as a faster, further and smarter LiFePO4 battery, its mini BCI Group 24 size (L260 x W168 x H209mm) and light weight (11.1kg) can help you to save more boat weight and spare space, letting you have more space to catch more fish.
Connecting your smart 12V 100Ah Trolling Motor Battery takes just 3 simple steps: Download the WattCycle App, Search for your Bluetooth battery, and Select the battery on the App. You can not only check the battery's SOC, voltage, current and the power, but also control charging or discharging.
WattCycle has now released a new feature to bind your battery and your account, which means only you can control the battery. This is specially designed to protect your battery from unauthorized operation.
Compared to lead-acid batteries that can only discharge 50%, WattCycle 12V 100Ah Trolling Motor LiFePO4 batteries can be discharged 100% and cycled 5.000 times @ 100% DoD. The 12V 100Ah Trolling Motor battery is IP67 waterproof, which is safer than lead-acid batteries when used at sea and has a longer service life. Its lightweight design also reduces the weight of your boat.
There are three ways to charge the 12V 100Ah Trolling Motor LiFePO4 battery. You can charge it with an AC-DC LiFePO4 battery charger, a generator, or the solar panel and MPPT when sailing at sea.

Yes. Two identical 12V LiFePO4 batteries can be connected in series to create a 24V battery system.
With integrated Bluetooth 5.0 connectivity and real-time status monitoring, you can easily track voltage, charge levels, and overall health via our dedicated mobile app. Please read the WattCycle detailed Bluetooth Guide.
We recommend charging the battery fully with a compatible LiFePO4 charger before its initial use and maintaining a 30%–50% charge for long-term storage to ensure optimal performance.
Yes. The battery features an IP67 waterproof rating and rugged construction designed for harsh marine environments.
Our advanced BMS continuously monitors the current flow and instantly disconnects power if it detects an overload, ensuring that neither the battery nor your devices are exposed to harmful currents.
This proactive overcurrent protection automatically resets once safe conditions resume, maintaining optimal performance and extending the battery’s lifespan.
In most trolling motor applications LiFePO4 lithium batteries offer clear advantages over lead acid. They are lighter, deliver a higher usable energy percentage, charge faster, and provide a much longer cycle life with less maintenance. The trade offs are higher upfront cost and the need to use LiFePO4 compatible chargers or charging profiles.
Yes, a 12.8V 100Ah LiFePO4 battery can run a 55lb trolling motor, provided the battery and wiring can handle the motor's continuous current draw. Example calculation: 12.8V × 100Ah = 1,280 Wh. A 55lb motor drawing about 40 A uses roughly 12V × 40A = 480 W, so estimated runtime = 1,280 Wh ÷ 480 W ≈ 2.8 hours. Real runtime depends on propeller, boat load, speed setting, and environmental conditions.
"Marine battery" is a broad term that can include starting batteries, deep cycle batteries, and dual purpose batteries used in boats. A "trolling battery" specifically refers to a deep cycle battery built to supply steady current for electric trolling motors over long durations. Key differences include design for cranking versus deep-cycle discharge, plate construction and thermal management, and typical use cases such as starting a gasoline outboard or powering electronics and electric propulsion.
