REYTRIC 2-Pack 2500mAh X4 Replacement Batteries - Extended Run Time

In this review of the REYTRIC 2-Pack 2500mAh X4 Replacement Batteries, the bottom line is simple: this kit is aimed at active Insta360 X4 users who need significantly longer recording time and a safe way to charge and carry spare power. The package includes two 2500mAh cells and a palm-sized USB-C fast charging case that also stores two micro SD cards, making it a practical travel companion. The single biggest reason to buy is the doubled runtime for long shoots: the batteries support up to 135 minutes at 5.7K 30fps, which noticeably reduces interruptions during a day of action filming.

Key Features

• Capacity: Each battery is 2500mAh 3.85V (9.63Wh), offering extended continuous recording for longer sessions without swapping often.
• Extended runtime: Two batteries double on-camera time, supporting up to 135 minutes of recording at 5.7K 30fps for fewer interruptions during shoots.
• Fast charger case: The included palm-sized USB-C charging case charges batteries on the go and can fully recharge a battery in about 78 minutes with the specified input/output.
• Safe charging: An integrated intelligent control chip provides over-charge, over-discharge, over-voltage, over-current and over-heating protections for safer use.
• Micro SD storage: The charger case stores two micro SD cards so replacement media and spare power travel together neatly.

Who It's For

This kit is best for action camera users who shoot long sessions, travel, or capture events where access to mains power is limited; vloggers, adventure photographers, and travelers will appreciate the doubled battery supply and portable charger case. The storage for micro SD cards makes it a practical carry solution so media swaps and battery swaps happen in one place.

Users who prioritize factory-branded batteries for warranty reasons or who require guaranteed waterproof battery packs for submerged use should consider official manufacturer options, since customer reports show mixed experiences with water resistance for spare batteries.

Pros & Cons

Pros

• High capacity 2500mAh cells that extend shooting time and reduce downtime between charges.
• Convenient USB-C fast charging case that recharges batteries quickly and holds two micro SD cards for tidy storage.
• Multiple circuit protections and intelligent charging behavior protect battery health and safety.

Cons

• Water resistance is mixed in customer reports, so these batteries should not be assumed waterproof for underwater use.
