Off-Grid, Backup, and Solar Batteries

Shop LiFePO4 Batteries for Solar, Off-Grid, and Home Backup

Whether you're building a whole-home backup system, designing an off-grid cabin, or expanding a mobile setup, you’ll need a battery bank for energy storage. Current Connected stocks LiFePO4 batteries (Lithium Iron Phosphate) from trusted brands like EG4, Pytes, Epoch, Victron, Fortress Power, BigBattery, and more. We carry batteries with UL 1973, UL 9540, and UL 9540A certifications, and we provide US-based technical support for all your alternative energy needs.

Modern LiFePO4 chemistry delivers thousands of charge cycles, improved safety, and advanced features not found in traditional lead-acid alternatives. You can use them for up to two decades as whole home backup during outages or for daily use when connected to a solar array.

Our off-grid, backup, and solar batteries include 12V, 24V, or 48V options. Battery capacity ranges from 30Ah to 600Ah with 100Ah, 200Ah, 280Ah, or 314Ah as our most popular choices. If you need help deciding, feel free to contact us. Our friendly and knowledgeable support staff looks forward to chatting with you.

Choose by Voltage and Capacity

System voltage must match across components.
12V LiFePO4 Batteries: Best for RVs, vans, boats, and small mobile systems.
24V LiFePO4 Batteries: Ideal for mid-size cabins and modest off-grid loads.
48V LiFePO4 Batteries: The standard for whole-home backup, residential solar, and sometimes used in commercial energy storage.
HVDC LiFePO4 Batteries: Used in commercial energy storage.

Find the Right Form Factor

48V Server Rack Batteries: This is our most popular category as it provides modular 19" rack-mount LiFePO4 batteries with 5.12kWh of energy storage. Our rack mount batteries include options from EG4, Pytes, Eneramp, Rich Solar, and ECO-WORTHY.

This size allows you to purchase one or two batteries for a small battery bank or purchase many batteries for commercial energy storage up to 150+ kWh. If you need a high voltage system, we also sell Sol-Ark’s HVDC (300V+) energy storage bank.

Wall Mount Lithium Batteries: 48V wall mount batteries save valuable floor space in your garage or utility room and provide 9.98kWh, 10.24kWh, 14.34kWh, or 16kWh of renewable energy storage. Many models include internal heating for use in cold climates and an ingress protection rating of IP65, making them both dustproof and water resistant.

Mobile and RV Batteries: We sell 12V, 24V, and 48V LiFePO4 batteries designed for RVS, boats, and other mobile off-grid alternative energy systems. Options include heated, Bluetooth-enabled, and Victron-communication-ready batteries.

High-Capacity Stackable Systems: Stackable LiFePO4 battery systems can grow with your needs. They’re designed for simple installation and often click together so you don’t need to run wires between batteries or from the battery bank to the stackable inverter.

Built for Real-World Conditions

Need a battery that survives a Northern Idaho winter or a coastal saltwater environment? We carry internally heated batteries for cold-weather operation, IP65 and IP66 rated outdoor batteries for exterior installation, and rapid-shutdown-equipped models that meet residential code requirements. Most batteries include an advanced Battery Management System (BMS) with cell balancing, temperature compensation, and protection against overcharge, over-discharge, and thermal events.
