48V 100Ah Marine House Battery for Onboard Power
Designed for onboard living power, this 48V 100Ah marine house battery delivers 5120Wh of energy to support lights, fridge, small appliances. Instead of focusing on propulsion, this battery is better positioned for boaters who need stable stored energy for leisure boating, overnight stays. Its LiFePO4 chemistry supports repeated deep-cycle use, making it a practical power source for marine house systems where long-lasting energy storage and easier power management are both important.
Built for Marine House Power
Designed for daily onboard power needs, this 48V 100Ah LiFePO4 battery delivers 5.12kWh usable energy and supports up to 5.12kW continuous load power for boat essentials such as lights, refrigerators, electronics, pumps, and small appliances. With a 100A BMS, EV-grade cells, Bluetooth 5.0 visibility, and up to 15,000 cycles, it provides reliable long-term power for marine use.
Bluetooth 5.0 Monitoring for Marine House Power
Bluetooth 5.0 gives this marine LiFePO4 battery clearer power visibility during daily onboard use. Through the LiTime App, users can check SOC, voltage, current, and other data from their phone, making it easier to understand whether the battery bank can support lights, fridge, appliances before the next trip. For marine house power systems, this wireless monitoring feature helps users plan energy consumption more confidently instead of guessing how much usable capacity is still available.
Shunt-Based Battery Monitor for Onboard Power Status
Paired with a compatible shunt and LiTime Battery Monitor, the battery system can display key power data such as voltage, current, power, SOC, and remaining capacity. This dedicated onboard screen helps boat owners check battery status from the helm without relying only on a phone.
Expandable 20.48kWh Onboard Power
For boaters who need more than a single battery, this 48V marine house battery supports 4P1S expansion up to 20.48kWh. The expandable design makes it easier to build a larger lithium battery bank for longer onboard energy needs, from daily low-power loads such as lights and electronics to higher-power loads for extended marine use.

Is this battery designed for marine house power or boat propulsion?
This 48V 100Ah marine battery provides 5120Wh of energy for onboard power needs such as lights, fridge, and small appliances. It is designed for marine house power, leisure boat energy storage, and compatible 48V propulsion systems.
Can I use just one 48V 100Ah battery on my boat?
Yes. One battery can be used as a 5.12kWh power source for compatible 48V onboard power setups. If your energy needs grow later, the system can also be expanded in parallel, giving boaters flexibility to start with one battery and build a larger battery bank over time.
How do I know if this battery can support my inverter?
Before use, please confirm that your inverter supports 48V input and that its rated power matches the battery’s output capability. The total connected load should not exceed the maximum output limits of both the battery and the inverter.
What charger should I use for this 48V 100Ah LiFePO4 battery?
Use a charger designed for 48V LiFePO4 batteries. The recommended charging voltage is 57.6V ± 0.8V, and the recommended charge current is 20A. 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, including SOC, voltage, current, and battery status. It helps boaters understand remaining battery power more clearly and plan onboard energy use before or during each trip.
What warranty and support does this battery include?
This LiTime battery comes with a 5-year warranty. If you need help with product selection, installation questions, charging compatibility, or after-sales support, you can contact LiTime customer service with your order information.
