Safety Recommendations

• Lithium-ion batteries can be dangerous if used incorrectly — follow the instructions.
• Avoid short-circuiting the terminals; this can lead to fire or explosion.
• Do not insert the battery into a device or charger with incorrectly connected terminals.
• Keep away from water, high temperatures, and mechanical damage.
• Store out of reach of children.
• Do not use modified or damaged chargers.
• Do not leave the battery in the charger for more than 12 hours.
• Dispose of in accordance with local legislation.

Please note that the absence of built-in protection means the need to use external protection boards (PCM/PCB) or controllers with appropriate protective functions in your device. Before installation, check compatibility in terms of dimensions and electrical parameters: height 71 mm, diameter 21.3 mm, weight 73.2 g. Product type: Drones and Quadcopters > Drone Batteries. Product name: LG INR21700-M58T 5570mAh Battery - 12.5A - Clear Wrap.

This cell is ideal for applications where maximum capacity in a compact size is a priority: long power supply for active electronic modules, autonomous systems, as well as hobby applications in modeling and drones. If you need a battery with built-in protection, choose a model with protection or install external protection boards.
