Redodo 12V 100Ah RV LiFePO4 Battery - Compact High-Capacity Power

In this review of the Redodo 12V 100Ah RV LiFePO4 Battery, the bottom line is simple: this is a compact, long-life replacement battery for RVs, trailers, boats and off-grid systems where space and weight matter. The reviewer found the Group 24 mini size and 25% reduced footprint made installation into existing battery boxes straightforward, while the 1280Wh capacity and built-in 100A BMS delivered reliable runtime and protection. For anyone upgrading from heavy lead acid cells who wants longer cycle life and easier handling, this battery shines.

Key Features

• Compact Group 24 Fit: Downsized housing matches BCI Group 24/27/31 boxes so it installs without modifying wiring or mounts.
• High Energy Density: 1280Wh capacity in a smaller case gives more usable energy per pound compared with similar-size lead acid options.
• Lightweight Design: At roughly 21.6 to 22.0 lbs it is dramatically lighter than comparable AGM batteries, simplifying swaps and reducing vehicle load.
• Durable Cycle Life: Grade A LiFePO4 cells and stated cycle life up to 15,000 cycles at 60% DOD promise many years of use before replacement.
• Integrated 100A BMS: Built-in battery management protects against overcharge, overdischarge, short circuit, high temperature and overcurrent for safer operation.
• Expandable Bank Options: Supports series-parallel connections up to 4S4P for larger 51.2V systems or expanded capacity for home or marine use.

Who It's For

This battery is ideal for RV owners, travel trailer and motor home users, and boaters who need a lighter, higher-density replacement for traditional lead acid Group 24 batteries. It suits those who want easy drop-in installation, multi-day power for appliances or reliable trolling motor support, and homeowners building compact UPS or small off-grid banks.

Those looking for a dedicated engine starter battery or a golf cart starter solution should look elsewhere for batteries designed specifically for starter cranking or high continuous discharge use beyond the listed applications. Also, installers who need OEM starter compatibility should confirm fit and terminal orientation before buying.

Pros & Cons

Pros

• Very good energy-to-weight ratio, making it simple to move and install.
• Long expected lifespan and high cycle ratings reduce replacement frequency and long-term cost.
• Built-in 100A BMS gives comprehensive safety protections out of the box.
• Fits standard Group 24/27/31 battery boxes for straightforward swaps from lead acid.

Cons

• Not intended as a starter battery for engines; intended for deep-cycle and accessory power applications.
• Maximum recommended charging sources and exact charge profiles should be followed to reach stated cycle life, which may require a compatible LiFePO4 charger or solar controller.

Frequently Asked Questions

Can this replace a Group 24 lead acid battery?
Yes. It is designed to fit Group 24 battery boxes and replaces lead acid batteries without extra wiring changes for accessory power.

What charging methods work with this battery?
Charge with a 14.6V LiFePO4 AC charger, a solar system (panels >400W recommended), or a generator; full charge in about five hours at 0.2C.

Can multiple units be connected for higher voltage or capacity?
Yes. The battery supports series-parallel expansion up to 4S4P for larger 51.2V systems or greater amp-hour banks.
