12V 100Ah Group 31 LiFePO4 Battery for Trolling Motors
$169.00
This 12V 100Ah LiFePO4 battery combines 1,280Wh of deep-cycle energy with CAN and RS485 communication for compatible Victron-based power systems. It is designed for RV house power, marine electrical systems and off-grid installations that require reliable battery data and coordinated system control.
Bluetooth monitoring provides convenient access to state of charge, voltage, current and temperature. A 100A Smart BMS manages charging, discharging and cell protection, while the Group 31 enclosure supports compatible lead-acid and AGM battery replacement projects.

The battery uses CAN communication to exchange operating information with a compatible Victron-based system. When the correct communication protocol, cable, firmware and system settings are used, connected equipment can receive battery data and respond to the permitted charging and discharging limits.
Available system information may include:
Compatibility must be confirmed against the Victron GX device, inverter-charger, firmware version, battery protocol and communication-cable pinout used in the project.
This is an independently manufactured LiFePO4 battery designed for compatible Victron-based systems. It is not manufactured, supplied or endorsed by Victron Energy.
Do not use an ordinary Ethernet cable unless its pinout and communication standard have been confirmed for both the battery and connected equipment.
Bluetooth monitoring gives RV owners, marine installers and service engineers direct access to battery information during system checks and routine maintenance.
Depending on the confirmed BMS and application version, the mobile interface may display:
Bluetooth range, mobile operating-system requirements and remote-control functions depend on the BMS hardware, firmware and application version supplied with the battery.
The integrated 100A Smart BMS monitors the battery during charging, discharging and storage. It protects the cells when voltage, current or temperature moves outside the configured operating limits.
The battery supports up to 100A continuous discharge and 1,280W of continuous output at nominal voltage. Inverters, fuses, cables, busbars and disconnect devices must remain within the battery and BMS ratings.
This model includes low-temperature protection but does not include self-heating.
When the cell temperature falls below 0°C, the BMS stops charging to help prevent cold-temperature cell damage. Charging becomes available again when the cell temperature reaches approximately 5°C.
Install the battery inside a dry, ventilated and securely mounted compartment. Low-temperature charging protection should not be described as self-heating.
The Group 31 enclosure makes this 12V 100Ah lithium battery suitable for selected lead-acid and AGM replacement projects. Before installing it in an existing system, confirm:
Changing from lead-acid to LiFePO4 may require a compatible charging profile, DC-to-DC charger or changes to the battery-monitoring configuration.
This 12V 100Ah deep-cycle battery can provide house power for compatible RVs, camper vans and mobile electrical systems. A safe installation should include correctly sized cables, a main fuse, battery disconnect switch and separate positive and negative busbars.
Positive circuit:
Battery Positive → Main Fuse → Battery Disconnect Switch → Positive Busbar → Inverter / DC Distribution
Negative circuit:
Battery Negative → Battery Monitor Shunt, when required → Negative Busbar → Inverter / DC Loads
If battery data is sent directly to a compatible Victron GX system through CAN communication, confirm whether the installation still requires a separate battery-monitor shunt.
The battery can supply compatible marine house-power and trolling-motor systems when installed inside a dry internal battery compartment. Use a corrosion-resistant tray, secure mounting system, protected terminals and marine-grade cables.
This is a deep-cycle battery. Do not use it as an engine-starting battery unless the required starting-current performance has been tested and approved for the engine.
When active communication is not being used, the reference configuration supports up to four batteries in series and four batteries in parallel, subject to the battery manual and confirmed BMS configuration.
Only connect batteries of the same model, capacity, BMS version, firmware revision and state of charge. Parallel branches should use equal-length cables and appropriate branch protection.
The battery uses a CC/CV charging profile with a reference charging voltage of 14.4V ± 0.2V and a recommended charging current of 20A.
Do not connect an alternator, generator or solar panel directly to the battery without appropriate charging equipment.
