12V 100Ah Group 31 LiFePO4 Battery for Trolling Motors
$169.00
This 12V 100Ah Group 27 LiFePO4 battery provides 1,280Wh of deep-cycle energy for compatible RV house-power systems, camper vans, marine auxiliary loads, trolling motors and off-grid applications. Built-in Bluetooth monitoring provides convenient battery status access, while the integrated 100A Smart BMS manages charging, discharging and cell protection.
Its Group 27 case also makes it a practical lithium replacement option for selected AGM and flooded lead-acid deep-cycle batteries after battery-compartment dimensions, terminal position, charger compatibility, cable size, fuse protection and maximum system load are confirmed.
The battery measures approximately 12.09 × 6.81 × 8.86 inches and weighs approximately 22.85 lb. Its Group 27 case format is intended for installations where the available battery compartment is designed around a similar footprint.
Group size alone does not guarantee a direct physical fit. Before replacing an AGM or lead-acid battery, confirm compartment dimensions, terminal clearance, cable routing, mounting space and battery orientation.

For compatible deep-cycle systems, this Group 27 LiFePO4 battery can be considered as a lithium replacement option for selected Group 27 AGM and flooded lead-acid batteries. The conversion should be based on electrical requirements rather than case size alone.
Before replacing a lead-acid battery with lithium, check the system voltage, charger profile, maximum charge current, expected discharge current, cable size, fuse protection, battery compartment dimensions and operating temperature.
Existing chargers with lithium-compatible CC/CV settings may be suitable when their voltage and current limits match the battery specification. Equalization and uncontrolled desulfation modes intended for flooded lead-acid batteries should not be used.
Review the Lead-Acid to LiFePO4 Battery Replacement Guide before changing the original charger, wiring or battery bank.
Bluetooth monitoring provides convenient access to battery status from a compatible mobile device. This is particularly useful when the battery is installed inside an RV electrical compartment, camper battery box or protected marine battery compartment.
Depending on the final battery monitoring configuration, available information may include:
The integrated 100A battery management system manages the battery during charging and discharging. It monitors electrical and temperature conditions and provides protection when operating conditions move outside programmed limits.
The battery supports up to 100A continuous charge current and 100A continuous discharge current, with maximum continuous output of approximately 1,280W. Peak-current requirements must be checked against the approved production specification before the battery is paired with a motor or inverter.
System design should still include correctly sized cables, fusing, disconnect protection and suitable charging equipment. The internal BMS should not be treated as a replacement for proper external circuit protection.
This battery includes low-temperature protection but does not include an internal self-heating system.
Charging is protected when cell temperature falls below approximately 0°C / 32°F. Charging can resume after cell temperature reaches approximately 5°C / 41°F, subject to the programmed BMS operating logic.
Discharge operation is specified down to approximately −20°C / −4°F. The battery should still be installed in a dry, protected compartment and operated within the specified temperature range.
The combination of a Group 27 case, 100Ah capacity, Bluetooth monitoring and a 100A Smart BMS makes this battery suitable for a range of compatible 12V deep-cycle applications.
In RV and camper systems, the battery can supply compatible 12V house loads such as lighting, control electronics, pumps, ventilation and inverter-supported appliances within the electrical limits of the installation.
The battery can be used in compatible marine house-power and auxiliary systems when installed in a dry, protected battery compartment with appropriate fusing, disconnect protection, cable sizing and terminal protection.
For a 12V trolling motor system, battery selection should be based on the trolling motor's rated voltage, continuous current demand, peak current and required runtime. Confirm the motor manufacturer's electrical requirements before installation.
The specified charging method is CC/CV, with a charge voltage of approximately 14.4V ± 0.2V. The recommended standard charge current is approximately 20A.
Use the LiFePO4 battery system compatibility guide to check charger, inverter, solar controller, alternator charging, cable size and fuse protection as one complete system.
The battery platform supports approved series and parallel configurations up to the limits specified for the product. When building a multi-battery bank, use batteries of the same voltage, capacity, BMS configuration and similar production age.
Before connecting batteries in series or parallel, confirm final system voltage, cable size, fuse rating, busbar capacity, charger configuration and inverter requirements.
Do not mix batteries with different capacities, chemistries, BMS ratings or significantly different states of charge in the same battery bank.
