12V 100Ah LiFePO4 Battery Group 24 - Lightweight Deep Cycle Power

In this review the CHITOLI 12V 100Ah Group 24 LiFePO4 battery is examined for owners who want a direct, lighter replacement for lead-acid house batteries. The bottom line: it is a purpose-built deep cycle battery for energy storage and accessories, not engine starting, and its main advantage is a dramatic reduction in weight and size while delivering long cycle life and stable performance thanks to automotive grade LiFePO4 cells and a built-in smart BMS.

Key Features

• Lightweight, compact design: At about 22.57 lbs and Group 24 dimensions, it is roughly 60% lighter and 35% smaller than comparable lead-acid batteries, making installation and handling much easier.
• Long cycle life: The battery is rated for thousands of cycles (4000+ at 100% DOD, rising to 15000 cycles at 60% DOD), offering multi-year service for repeat deep-discharge use.
• Built-in smart BMS: The integrated 100A BMS protects against overcharge, over-discharge, over-current and short circuit, improving safety and reliability in varied conditions.
• Group 24 compatibility: Sized to the common BCI Group 24 standard so it fits many boxes and mounts as a drop-in replacement for lead-acid and AGM battery banks.
• Fast recommended charging: The manufacturer recommends a 14.6V and 20A charge profile for a full charge in about 5 hours, helping return the battery quickly to service.

Who It's For

This battery is best for RV owners, campers, anglers using trolling motors, and small off-grid systems that need reliable, lightweight deep cycle power for appliances, electronics and motors. It excels where weight and space matter and where repeated deep discharge cycles are expected.

It is not intended as a starter battery for internal combustion engines, so anyone needing high cold-cranking amps to start a vehicle should look for a dedicated starting battery. Also, users who cannot match the recommended charging profile on their existing charger should verify compatibility before switching.

Pros & Cons

Pros

• Significantly lighter and more compact than comparable lead-acid batteries, easing installation and transport.
• Exceptional cycle life based on automotive grade LiFePO4 cells, translating into lower lifetime replacement cost.
• Built-in smart 100A BMS adds protections that increase safety and battery longevity.

Cons

• Designed for energy storage and accessories rather than engine starting, so it cannot replace a starter battery.
• Proper lifespan and performance depend on using the recommended charge voltage and current, which may require charger adjustment.
