Vatrer 51.2V 100Ah LiFePO4 Lithium Solar Battery, Built-In 100A BMS, Max. 5120W Load Power, Bluetooth Version EU - 1 PACK

Server Rack Battery Design Saves Space When you’re building power for an off-grid cabin, RV electrical system, home solar backup, or small business energy setup, you need a battery that can store enough energy without making the whole system bulky. This Vatrer 51.2V 100Ah LiFePO4 battery provides 5120Wh of usable energy in a compact server rack format, giving you steady power for lights, appliances, communication devices, backup loads, and solar storage equipment. Instead of spreading multiple smaller batteries across your space, you can keep your power system cleaner, easier to manage, and ready for future expansion.

Built-In 100A BMS Protects the Battery Inside this 48V 100Ah LiFePO4 battery, the built-in 100A BMS continuously monitors voltage, current, charging, discharging, short circuits, and temperature conditions. When you’re using the battery in an RV, garage, cabin, or solar storage room, this protection helps reduce the risk of damage caused by overcharge, over-discharge, overload, or abnormal operating conditions. In cold weather, the system stops charging below 32°F and stops discharging below -4°F, helping protect the LiFePO4 cells during seasonal or low-temperature use.

LCD and Bluetooth Show Battery Status You should not have to guess how much energy is left in your storage system. This Vatrer battery includes a built-in LCD touchscreen and Bluetooth App monitoring, allowing you to check battery level, voltage, current, and temperature in real time. The LCD display gives you quick on-site access when you are near the battery cabinet, while the app makes it easier to monitor the system from your phone when the battery is installed in an RV compartment, equipment room, or home solar setup.

Lightweight Rack Battery for Easier Installation Compared with traditional lead-acid batteries, this lithium rack battery is built with an SPCC steel shell and is roughly 70% lighter than comparable lead-acid alternatives, making installation and handling more manageable. That difference matters when you’re placing the battery in an RV, wall-mounted cabinet, storage rack, or solar power room where weight support and installation space both need to be considered. The compact rack-mounted structure also helps reduce clutter and makes future system maintenance easier.

Parallel Expansion, Up to 51.2kWh If your current energy needs are modest but your system may grow later, starting with one 51.2V 100Ah LiFePO4 battery keeps the setup modular. Up to 10 units can be connected in parallel, expanding total storage to 51.2kWh with up to 51.2kW system output when properly configured. This matters for off-grid homes, farms, small workshops, and business backup systems where energy demand can increase as more appliances, tools, or solar panels are added.

Rather than replacing the whole battery bank, you can build your storage capacity in stages as your usage becomes clearer. Flexible Charging, Better for Real Setups This 48V 100Ah LiFePO4 battery can recharge in about 5 hours with a 58.4V 20A LiFePO4 charger, about 3.3 hours through a 30A DC-to-DC charging setup, or through a 48V MPPT solar input above 1500W. For RV travel, that means your battery can work with shore charging, alternator-based charging, or solar recovery depending on where you are parked.

For off-grid homes, multiple charging paths also make it easier to balance daily solar production with backup charging needs. Clean Energy Storage Without Acid Maintenance Lead-acid batteries require more attention over time, including checking for corrosion, managing acid-related risks, and dealing with heavier battery banks. This Vatrer battery uses LiFePO4 chemistry, so it does not produce acid leaks and does not require watering like flooded lead-acid batteries.

With a 5.12kWh capacity and long-cycle lithium design, it supports solar energy storage, home backup, RV travel, and other renewable power applications where lower maintenance and cleaner operation matter in day-to-day use. Built for RV, Solar, Marine, and Backup Power A single 48V 100Ah LiFePO4 battery can support a wide range of energy storage needs when matched with the right inverter, charger, and system design. In an RV, the compact rack format helps save space while providing 5120Wh of usable energy storage for daily electrical loads.

In an off-grid home or cabin, it can store solar power for lighting, communication, refrigeration, and other essential equipment. In marine or business backup applications, the stable 48V-class lithium platform helps reduce reliance on fuel-powered backup sources when the system is properly configured. Build Your Energy System with Vatrer Battery If you are planning a solar lithium battery bank, RV power upgrade, or home backup system, the Vatrer 51.2V 100Ah LiFePO4 battery gives you a clear starting point: 5.12kWh capacity, built-in 100A BMS protection, LCD and Bluetooth monitoring, and expansion up to 10 parallel units.
