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.
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.
Unleash Reliable Power for Your Marine Adventures
Experience steady power on the water with the LiTime 48V 30Ah Lithium Battery. Featuring a robust 100A BMS, it delivers stable output with a maximum continuous discharge current of 80A and a 300A peak discharge for 1 second. Whether cruising, accelerating, or powering a 48V marine motor system, it provides dependable performance for smoother and more confident boating.
Power Through Your Round with Championship Battery Cells
The LiTime 48V (51.2V) 30Ah marine battery has 4000+ deep cycles at 100% DOD. Their robust cylindrical construction dissipates heat efficiently for durable rounds in any conditions. With a fast 2.67C discharge, these cells are rated for a full 100% discharge depth, more than double the capacity of lead-acid batteries which can only manage 50-60% at 1C.
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. This expandable design gives users the flexibility to build a larger lithium battery bank for extended leisure use, off-grid boat power, and longer onboard energy needs. Whether powering daily appliances or supporting compatible inverter loads, the system can grow with the boat owner’s setup instead of being limited to one fixed capacity.
3 Charging Ways, 10X Fast Charging
LiTime lithium battery can be charged via a LiFePO4 charger, solar panel or generator, making it easy and convenient to use. Its 1C charging efficiency makes it fully charged in about 1 hour at the fastest (10X of the lead-acid battery). Without the memory effect, you can charge it partially or fully anytime.
Low Energy Consumption, Free Maintenance, Extremely Low TCO
LiTime 51.2V 30Ah marine smart LiFePO4 Battery only consumes an average of 71.68Wh/km and serves you over 10 years. It has better performance in shock resistance, durability and lightweight, making it flexible in installation. Not requiring intermediate replacement and regular maintenance, it is almost maintenance-free.
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.
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.
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.
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.
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.
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.
