Batteries

Learn more about batteries

Fuel your energy independence with high-performance batteries engineered for solar, off-grid, RV, and emergency power systems. Whether you're storing energy from solar panels or building a backup power solution, EcoGridSupply batteries deliver long-lasting reliability, deep cycling capability, and scalable performance for every application.

How EcoGridSupply Batteries Work

Batteries are the heart of any off-grid or hybrid power system—storing energy for use when the sun isn’t shining or the grid goes down. At EcoGridSupply, we offer deep-cycle lithium and AGM batteries designed to provide consistent, stable power over thousands of cycles. These batteries integrate seamlessly with solar charge controllers, inverters, and generators, creating a balanced system built to last.

Choosing the Right Battery Capacity for Your System

Selecting the right battery setup is essential for maximizing uptime and minimizing maintenance.

  • 100Ah–200Ah Batteries: Great for RVs, vans, boats, and mobile setups.
  • 300Ah–600Ah Batteries: Ideal for cabins, tiny homes, or medium-scale solar systems.
  • 1000Ah+ Banks: Built for whole-home systems, off-grid living, and commercial-grade backup power.

Use our system specs or reach out to our expert support team for help sizing your bank based on your daily energy consumption, inverter wattage, and autonomy needs (how long you want to run without sun or grid).

  • Expert-curated brands tested for real-world performance
  • Industry-leading warranties and technical support
