Battery Kit for Xiaomi Yi 2 4K by Cameron Sino — 2× Replacement Batteries + Charger (MPN SB7529)

This Battery Kit for Xiaomi Yi 2 4K by Cameron Sino includes two replacement lithium-ion batteries and a dedicated charger designed to extend recording time and simplify battery management for the Xiaomi Yi 2 4K action camera. The kit provides extra capacity for extended shoots, quicker battery swaps on location and a compact charger suitable for travel. It is intended as a power accessory to maintain continuous operation during sports, travel and other prolonged recording scenarios.

Advantages

The kit supplies two identical replacement batteries that increase available run time without relying on the camera’s internal battery alone. A separate charger allows you to charge batteries outside the camera, enabling uninterrupted filming by swapping charged cells. The charger is compact and designed for easy transport, and the batteries are lightweight to avoid adding bulk to your camera bag.

Suitable for

• Extended action-sports recording sessions
• Travel and outdoor shoots where access to power is limited
• Time-lapse sequences and long continuous recordings
• On-location battery swaps to minimise downtime

Key specifications

• Battery type: rechargeable lithium-ion cells compatible with Xiaomi Yi 2 4K
• Number of batteries: 2 replacement batteries included
• Charger type: dedicated external charger for the included batteries
• Charger input/output: designed for standard USB power sources (USB cable required or included depending on package)

How to use

Before first use, charge both replacement batteries fully in the dedicated charger using a compatible USB power source. Power off the Xiaomi Yi 2 4K camera, open the battery compartment and replace the existing battery with a charged replacement by inserting it with correct polarity until it seats securely. Use the external charger to charge spare batteries while the camera is in use so you can swap cells as needed for continuous recording. Follow the camera manufacturer’s instructions for battery handling and contact points to ensure reliable connection.

Usage recommendations

Store batteries at moderate temperature and avoid prolonged exposure to high heat or direct sunlight. Charge batteries using the provided charger and a suitable USB power source; avoid using damaged cables or adapters. For long-term storage, keep batteries at around 40–60% charge and check them periodically. Dispose of worn batteries according to local electronic waste regulations.
