Compact 48V Lithium Battery for Electric Outboards
This compact 48V marine lithium battery is designed for compatible 48V electric outboards and small-boat power setups. With 1536Wh of energy, it supports light trips and short-distance cruising while keeping the battery footprint smaller for easier installation in tight onboard spaces. It is a practical choice for boaters who want a simpler 48V setup today with the flexibility to expand capacity later.
Power Your Marine with Confidence
Upgrade your 48V marine setup with the LiTime 48V 30Ah marine lithium battery. With 60A max continuous discharge and 300A peak discharge for 1 second, it supports high-current output for acceleration, starting demands, and demanding onboard power use.
Optimized BMS for Stable Marine Power
Equipped with a custom 60A BMS, this marine battery helps protect against abnormal conditions such as overcurrent, short circuit, overcharge, and over-discharge. Combined with EV-grade high C-rate cells, it helps manage surge demands safely, reduce heat buildup, and support dependable performance on the water.
Bluetooth Battery Monitoring for Small Boat Power
With Bluetooth 5.0, this compact 48V LiFePO4 marine battery lets boaters check SOC, voltage, current, and other key data through the LiTime app. Real-time battery data makes it easier to plan power use before leaving the dock and manage remaining energy during time on the water. With clearer battery visibility, boaters can plan each trip and manage power use with more confidence.
Space-Saving 48V Battery with 12.28kWh Expansion
Although compact in size, this 48V electric outboard battery supports 8P1S expansion up to 12.28kWh, giving users room to scale when longer runtime is needed. A single battery can work well for lighter trips, while multiple batteries can be connected to increase total capacity for longer use. This makes it a flexible choice for boaters who want a space-saving 48V power solution now, with the option to expand their battery bank later as their boating needs grow.
Lightweight and Performance-Driven Battery
Compared with traditional lead-acid batteries, LiFePO4 batteries offer higher energy density in a lighter and more compact design. This helps reduce onboard weight, simplify installation and handling, and support better energy efficiency. With nearly 3.3 times the lifespan and lower maintenance needs, this battery provides reliable, long-lasting power for marine use.
Lower Total Cost of Ownership (TCO)
Compared with traditional lead-acid batteries, the LiTime 51.2V 30Ah marine LiFePO4 battery offers a longer service life with fewer replacements and lower maintenance needs. With over 4,000 cycles and a lifespan of up to 10 years, it delivers reliable long-term power with only basic preventive care.

What type of boat setup is this 48V 30Ah battery best for?
This battery is best for boaters who need a compact 48V power source for compatible electric outboards and small-boat setups. It is a practical choice for light trips, short-distance cruising, and installations where battery space is limited.
Why is this called a 48V battery if the nominal voltage is 51.2V?
51.2V is the nominal voltage of a 16-series LiFePO4 battery pack. It is commonly used as a lithium replacement for traditional 48V nominal battery systems.Before purchase, please confirm that your electric outboard, charger, or onboard equipment is compatible with a 48V LiFePO4 battery system.
How long can this 48V 30Ah marine battery run an electric outboard?
Runtime depends on motor power, speed setting, boat weight, water conditions, and how the boat is used. A simple estimate is to divide the battery’s energy by your motor’s power consumption. Lower speed settings usually provide longer runtime, while full-throttle use will consume power faster.
Read more on how long do marine batteries last?
Can I start with one battery and expand later?
Yes. One battery can be used for lighter trips or compact 48V setups. If more runtime is needed later, the battery supports parallel expansion up to 8P1S, allowing users to build a larger capacity system over time.
What charger should I use for this 48V marine battery?
Use a charger designed for 48V (51.2V)LiFePO4 batteries. The recommended charging voltage is 57.6V ± 0.8V, and the recommended charge current is 6A. Using the correct charger helps support proper charging and long-term battery performance.
What can I check through Bluetooth monitoring?
Bluetooth monitoring lets users view key battery data through the LiTime app, such as SOC, voltage, current, and battery status. It helps boaters understand remaining power more clearly and plan power use before or during each trip.
