Li-Ion battery INR18650 Akyga AKY2455 3.7V / 2900mAh with protection

The Akyga® AKY2455 is a modern INR18650 lithium-ion battery, combining a compact design, a 2900 mAh capacity, and built-in PCM protection. This solution is dedicated to users who expect not only performance but also reliable battery protection under all operating conditions.

PCM circuit ensures safety

Powering portable devices often exposes batteries to intensive use and, at times, user errors. That's why the AKY2455 Li-Ion 18650 battery is equipped with a PCM (Protection Circuit Module) circuit, which plays a crucial role in protecting both the battery and the connected devices. It provides protection against:

• overcharge,
• excessive discharge,
• short-circuit,
• and current overload.

This allows the AKY2455 18650 Li-Ion battery to be used without additional external protection, significantly simplifying installation and increasing the safety of the entire power system.

Who is the Li-Ion 18650 battery with PCM recommended for?

This 18650 cell is suitable for both commercial and private applications – especially in projects where reliability is essential, but there is no time or space to implement external protection systems.

Cells with built-in protection are an ideal choice for:

hobbyists and DIY enthusiasts who want to avoid the complexities of designing their own protection circuits,

manufacturers of small electronic devices where space and assembly time are limited,

service technicians and installers who need ready-made, safe cells for quick replacement,

and anyone using batteries in power banks, flashlights, sensors, IoT systems, RC devices, and many other mobile applications.

A protected 18650 cell designed to work

The 18650 Li-Ion battery is based on proven INR technology, which ensures high energy density while maintaining high current efficiency. As a result, the AKY2455 cell provides efficient power for devices with moderate or temporarily increased current consumption, while maintaining thermal resistance and voltage stability even during intensive use.

Technical specifications – what you need to know

The Akyga® AKY2455 18650 battery has a standard cylindrical housing with a diameter of 18.5 mm and a height of approximately 70 mm (including built-in PCM protection). Its nominal voltage is 3.7 V, and its actual capacity is 2900 mAh, which means a solid energy reserve while maintaining a small size. The battery operates in the typical operating temperature range (-20 °C to 60 °C), and the INR (LiNiMnCoO₂) technology used allows for a continuous discharge current of 1.5 A without the risk of overheating or performance degradation. The built-in PCM system actively protects the battery by shutting it down when thresholds are exceeded – all without additional external electronics.
