Renogy Rego Series 12V 400A Lithium Iron Phosphate Battery

Renogy REGO Series 12V 400Ah LiFePO₄ Battery

5.12kWh of uncompromising power. Built for the toughest demands.

The Renogy REGO Series 12V 400Ah Lithium Iron Phosphate Battery is a high-capacity, professional-grade energy solution designed for users who need maximum runtime, extreme durability, and long-term reliability. With a massive 5.12kWh energy capacity, this battery is engineered for off-grid homes, marine systems, RVs, and high-draw applications where performance cannot be compromised.

Built around premium LiFePO₄ chemistry and housed in a rugged die-cast and extruded aluminium enclosure, the REGO Series delivers industrial-level strength with intelligent energy management — ready for years of demanding use.

 Massive capacity. Serious output.

With 400Ah at 12.8V, this battery provides exceptional energy density in a single unit. High continuous charge and discharge currents allow it to support powerful inverters, heavy appliances, and demanding electrical loads with ease — eliminating the need for complex multi-battery setups.

Designed exclusively for parallel connections (up to 8 batteries), the system scales cleanly and safely to deliver over 40kWh of total capacity for large off-grid installations or extended runtime requirements.

Automatic self-heating for cold-weather reliability

Integrated automatic self-heating ensures safe and reliable charging in low-temperature environments. When conditions drop, the battery intelligently warms itself to maintain optimal performance — keeping your system running when other batteries fail.

 Built like industrial equipment

The REGO Series isn’t just powerful — it’s engineered to last:

• Die-cast & extruded aluminum housing for superior structural strength
• IP65 protection against dust and water ingress
• Advanced internal protections to handle vibration, high loads, and harsh environments

This is a battery built for real-world conditions, not controlled lab setups.

 Exceptional longevity

Delivering 6,000 cycles at 80% depth of discharge, the REGO Series dramatically outlasts traditional lead-acid and standard lithium batteries — reducing replacement costs and long-term ownership expenses while ensuring dependable power year after year.
