Electric Outboard Battery 51.2V 100Ah 5120Wh Bluetooth IP54 M8 Terminals
Purpose Built for Marine Applications
This 51.2V 100Ah LiFePO4 battery is specifically designed for
electric outboard motors, trolling motors, and marine house banks.
Storing 5120 watt hours of energy, it provides long runtime on the
water without the weight or maintenance of lead acid batteries. The
low profile 133mm height allows installation under decks or in
tight compartments. IP54 rated SPCC housing resists splashes and
dust, while Bluetooth connectivity enables remote monitoring from a
smartphone.
Core Electrical Specifications
Nominal voltage is 51.2V with 100Ah rated capacity and total energy
of 5120Wh. Internal resistance is ≤30 milliohms. Efficiency reaches
98 percent. Self discharge is less than 5 percent per month. The
battery uses 16 cells in series with 1 parallel string (16S1P).
Dimensions are 460mm width, 480mm depth, and 133mm height. Weight
is 48 kilograms. Terminal type is M8. Housing is SPCC steel with
IP54 splash protection. Bluetooth communication is built in for
real time monitoring.

Discharge Performance
Continuous discharge current is 150 amps, enough to power a large
trolling motor or multiple marine electronics simultaneously. Pulse
discharge current reaches 500 amps for less than 500 milliseconds,
providing surge current for outboard motor starting or sudden load
spikes. BMS discharge cut off voltage is 40V with reconnect at
43.2V. Recommended voltage disconnect is also 40V. Short circuit
protection activates within 300 to 800 microseconds.

Charge Parameters
Charging uses the CC CV method with charge voltage range of 56.8V
to 58.4V. Recommended float voltage at full charge is 53.2V to
53.6V. The recommended charge current is 25 amps (and also listed
as maximum charge current). BMS charge cut off voltage is set to
59.2V, providing a small buffer above the standard 58.4V to
accommodate charger variations.

Cycle Life and Reliability
Rated for over 4000 cycles at 1C charge/discharge rate and 80
percent depth of discharge while retaining over 80 percent of
original capacity. For a boater who cycles the battery once per day
during fishing season, this translates to over 10 years of service.
The low self discharge means the battery holds its charge between
trips.
Temperature Range
Discharge temperature range is -20°C to 60°C, suitable for cold
spring mornings and hot summer days on the water. Charge
temperature range is 0°C to 55°C. Storage temperature range is 0°C
to 35°C. BMS high temperature cut off is 65°C.

| Charge Temperature | 0℃ to 55℃ | |
| Storage Temperature | 20℃ to 60℃ | |
| BMS High Temperature Cut-off | 65℃ | |
Bluetooth Monitoring
Built in Bluetooth allows connection to a smartphone app. Monitor
battery voltage, current, state of charge, temperature, and cycle
count in real time. Receive alerts for low voltage or high
temperature. No additional monitoring hardware is needed.
Marine Specific Benefits
Compared to lead acid marine batteries, this LiFePO4 battery offers
significant advantages. Weight is approximately half of lead acid
(48kg vs 90kg+ for equivalent usable capacity). Usable capacity is
100 percent compared to 50 percent for lead acid. Cycle life is
4000+ vs 300-500 for lead acid. No watering, no terminal corrosion,
no acid spills, and no explosive hydrogen gas during charging. The
battery is sealed and can be mounted in any orientation.
