Renogy Rego 12.8V 104Ah is an ultra slim solid State LiFePO4 battery.

The Renogy Rego 12.8V 104Ah Solid State LiFePO4 battery offers a compact, ultra-slim design—just 61 mm deep—making it ideal for tight installations such as behind seats, under floors, or on canopy walls. 

Built for versatility and durability, it comes with vibration-resistant mounting brackets that ensure a secure fit even in demanding mobile environments.

Leveraging solid-state cell technology
This next-generation lithium battery leverages solid-state cell technology, reducing liquid electrolytes by 70%. The result is a major leap in safety and lifespan, with a thermal profile that rises up to nine times slower than conventional lithium batteries—minimizing the risk of thermal runaway and enhancing system stability.

Despite its compact footprint, the Rego 104Ah battery delivers serious performance. It supports a continuous 200A output, powerful enough to run a 2000W inverter from a single unit. It also features reliable 10A charging capability even in freezing temperatures down to -10°C, making it suitable for year-round, off-grid use.

Safety is built into every layer of this battery
The integrated Smart Active Safety Design includes a high-performance BMS with over 60 protections against voltage spikes, short circuits, and extreme environmental conditions. A self-controlled fuse in the Active Backup Protection system adds an extra level of overcurrent response, ensuring your power system stays secure under load.

With its IP67-rated enclosure, the battery is fully protected from dust, moisture, and the elements, while the UL94 V-0 fire-resistant housing ensures it meets stringent safety standards. Whether you’re outfitting an RV, commercial vehicle, or custom off-grid system, this battery is engineered to perform—reliably, efficiently, and safely.
