$169.00
This 36V 100Ah LiFePO4 battery provides 3,840Wh of energy for compatible trolling motors, electric outboard motors and other 36V marine power systems. Bluetooth monitoring, a 100A BMS and low-temperature protection support practical battery management for demanding marine applications.
With a nominal voltage of 38.4V, the battery provides a single-battery solution for compatible 36V systems where the electrical, charging and installation requirements are suitable.
The 100A continuous discharge rating supports up to 3,840W of continuous output, while a short-duration 500A discharge rating is available for compatible surge loads.
38.4V | 100Ah | 3,840Wh | 100A BMS | 3,840W Continuous Output | 500A / 1s Peak | Bluetooth Monitoring | Low-Temperature Protection | IP65 | M8 Terminals
The battery measures approximately 20.47 × 10.55 × 8.66 inches. Before installation, confirm the available battery compartment, terminal clearance, cable routing and mounting space.
The battery uses M8 terminals. Allow sufficient clearance around the positive and negative terminals for cable lugs, protective covers and service access.
A single 38.4V 100Ah LiFePO4 battery can simplify compatible 36V marine installations by reducing the number of individual batteries, inter-battery cables and connection points required in the system.
This can make installation and routine service more straightforward in applications where a single 36V battery is electrically compatible with the trolling motor or electric propulsion system.
Compatibility should be confirmed using the motor voltage, continuous current, peak current, charger profile, cable size, circuit protection, available installation space and required operating time.
Bluetooth monitoring provides convenient access to battery operating information without opening the battery compartment for routine checks.
Depending on the compatible monitoring interface, battery information can include:
The integrated 100A battery management system monitors the battery during charging and discharging and provides protection when operating conditions move outside the programmed limits.
The battery supports up to 100A continuous charge current and 100A continuous discharge current, providing up to 3,840W continuous output.
A 500A one-second peak discharge rating supports compatible short-duration current demands.
Proper external circuit protection is still required. Fuse or circuit-breaker rating, battery disconnect, cable size and charging equipment should be selected for the actual system.
This battery includes low-temperature protection and 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.
Low-temperature discharge protection operates below approximately −20°C / −4°F.
The battery should remain installed in a dry, protected compartment and operated within the specified temperature range.
For compatible 36V trolling motors, the battery provides one 38.4V power source with 100Ah capacity and 3,840Wh of stored energy.
Battery selection should be based on the trolling motor's rated voltage, maximum current demand and required operating time rather than boat size alone.
The battery should be installed inside a dry, protected battery compartment with correctly sized positive and negative cables, suitable over-current protection and a battery disconnect.
The 100A continuous discharge rating and 500A one-second peak rating allow this battery to be evaluated for compatible 36V electric outboard motor applications.
Electric outboard motors can place different continuous and transient loads on a battery compared with conventional trolling motors.
Always confirm the electric motor manufacturer's rated voltage, maximum input power and maximum current before installation.
This battery is intended for compatible electric propulsion systems. It is not intended as a cranking or starting battery for gasoline or diesel outboard engines.
The specified charging method is CC/CV with a charge voltage of approximately 43.2V ± 0.6V.
The recommended standard charging current is approximately 20A. Charging equipment should be designed for the required battery voltage and LiFePO4 charging profile.
Use a compatible lithium battery charger with the correct CC/CV charging voltage and current limits.
Solar panels should connect through a compatible MPPT charge controller configured for the battery voltage and LiFePO4 charging requirements.
Generator output should pass through a compatible charger or inverter-charger rather than being connected directly to the battery.
Charger voltage, current and operating temperature limits should match the confirmed battery specification.
