Frequently Asked Questions

What is the difference between Lithium-ion and LiFePO4 batteries?

Lithium-ion batteries offer high energy density and are common in consumer electronics. LiFePO4 (Lithium Iron Phosphate) batteries are safer, have longer cycle life (up to 3000+ cycles), and better thermal stability, making them ideal for energy storage and outdoor use.

Can I use these generators for solar charging?

Yes, many of our models, such as the 600W LiFePO4 Solar Generator, are designed to be charged via solar panels. They support efficient solar input for off-grid and eco-friendly energy solutions.

Do you offer OEM/ODM services?

Yes, we provide full OEM and ODM services. We can customize battery capacity, output, casing, branding, and packaging based on your requirements.

What is the warranty on your battery generators?

We offer a standard 2-year warranty on all battery generators. Extended warranty options are available upon request.
