Solid Power in an Ultra-Thin Design

Extended Battery Life
Inherent Safety
Enhanced Protection

The Next-Gen LiFePO4 Cells

Renogy takes a step forward to introduce the solid state cells with 90% electrolytes in RV batteries (so far there is no solid state battery with 100% electrolytes on the market), bringing safety and lifespan to the next level.

Inherently Safe & Stable

The new Renogy slimline LiFePO4 battery introduces revolutionary solid electrolytes, ensuring that the battery does not swell or burn– even if punctured or crushed.

Safety At Its Heart

The Smart Active Safety Design helps this super slim lithium battery take a huge leap in sustained performance. The built-in battery management system (BMS) offers more than 60 protections against overvoltage, short circuits, extreme temperatures, and more. And with the self-control fuse in the Active Backup Protection, your battery will get an extra, more responsive protection when faced with overcurrent.

Sizing Guide

Before installing the battery, please note that you need to leave 1.97-3.94 in (50-100 mm) for the top of the battery; the side with busbars needs to be left at least 7.87 in (200 mm).

Super-Slim Design. Effortless Installation.

At just 2.4 inches (61 mm) thin, this battery fits behind seats, under floors, and in tight spaces—perfect for overlanding setups.

Travel Light with Confidence

Stop overloading your 4x4 pickup trucks with lead-acid batteries and AC generators. This 12V 104Ah Solid-State LFP Battery frees up space so you can carry what really matters.

Flexible Installation
Low-Temp Charging
UL94 V-0 & IP67 Protection

Easy to Mount in Any Setup

With versatile mounting kits, you can install this battery under seats, on canopy sides, or beneath the floor – secure and stable, no matter the terrain.

All-Season Performance

Whether in freezing cold or extreme heat, a single battery delivers 200A (2C) output while charging at temperatures as low as 14°F (-10°C)—keeping power steady through shifting temperatures.

Built Tough for the Wild

Built to handle the toughest conditions, this battery features an IP67-rated enclosure that shields against dust, water, and the elements. The UL94 V-0 fire-resistant rating adds an extra layer of safety, giving you the confidence to push further, no matter where the road takes you.
