Designed for compatible fish finder and sonar installations, this 16V 100Ah LiFePO4 battery provides a dedicated 1,600Wh power source for marine electronics.
A separate electronics battery can help isolate sensitive sonar and display equipment from other onboard electrical loads. Always confirm the permitted input-voltage range of each connected device before installation.
Fish finders and forward-facing sonar systems can place continuous demand on a boat's electronics power supply. A dedicated 16V LiFePO4 battery provides a separate source of power for compatible displays, sonar modules and related marine electronics.
The 100Ah capacity provides 1,600Wh of stored energy for installations where multiple electronics may operate for extended periods. Actual runtime depends on the number of connected devices and their combined power consumption.
Compatibility should always be confirmed from the electronics manufacturer's permitted input-voltage range. Do not connect equipment designed only for lower input voltages directly to a 16V battery.
Bluetooth monitoring provides convenient access to battery information without opening the battery compartment for routine checks. A compatible monitoring interface can display operating data before, during and after a day on the water.
Built-in self-heating supports charging in cold-weather conditions. When cell temperature is below the permitted charging range, the heating system raises battery temperature before normal charging begins.
The self-heating function is designed to prepare the battery for charging in low-temperature environments. Heating and normal charging are separate stages: the cells are warmed first, and charging proceeds after the required temperature condition is reached.
Self-heating and low-temperature BMS protection perform different functions. The heating system raises cell temperature before cold-weather charging, while BMS protection helps prevent charging or discharging outside the permitted temperature limits.
In cold-weather operation, the self-heating function should complete the required warming stage before normal charging begins.
The integrated 100A Battery Management System monitors voltage, current and temperature during battery operation and provides protection against operating conditions outside programmed limits.
Maximum continuous charge and discharge current are rated at 100A. At the 16V nominal voltage, maximum continuous output is 1,600W. Peak discharge current is rated at 500A for one second.
The battery uses a BCI Group 27-size enclosure measuring approximately 12.13 × 6.69 × 8.31 inches and weighs approximately 26.48 lb.
Before installation, measure the available battery compartment and allow sufficient clearance for terminals, cable routing, battery restraint and service access.
Use charging equipment configured for a compatible 16V LiFePO4 CC/CV charging profile. The reference charging voltage is 18V ± 0.25V, with a recommended charging current of approximately 20A.
Do not connect an AC source, generator or solar panel directly to the battery. Charging equipment must regulate voltage and current within the specified battery limits.
This 16V 100Ah LiFePO4 battery is intended primarily for compatible marine electronics that require a stable, dedicated deep-cycle power source.
Compatibility with specific fish finder and sonar models should be confirmed from the equipment manufacturer's permitted input-voltage specifications before installation.
The reference configuration supports up to four identical batteries connected in parallel while maintaining the same 16V nominal system voltage.
Use batteries of the same model, capacity, BMS configuration and state of charge. Parallel branches should use correctly sized cables and suitable overcurrent protection.
Series connection is not supported in the reference 4P1S configuration.
