Li-Ion Baterija INR18650 Akyga AKY2457 3.7V / 2000mAh with Protection

Akyga® AKY2457 is a compact and reliable INR18650 lithium-ion battery with a capacity of 2000 mAh , equipped with integrated PCM protection. It is a practical solution for those who need a cell ready for safe use — without the need for additional protective electronics. With an optimal balance between size, capacity and safety, the AKY2457 cell is ideal for powering everyday portable devices and DIY projects.

18650 battery with PCM protection

The integrated PCM (Protection Circuit Module) protects the battery against four critical risks:

• overcharging ,
• over-discharging ,
• short-circuiting ,
• and overcurrent .

This allows the 18650 cell to be used safely in devices that do not have their own protection systems, such as powerbank enclosures. It is the ideal solution for simple electronic circuits, prototypes and portable devices where reliability and ease of integration are key.

What is the 18650 cell suitable for?

The AKY2457 18650 battery is a versatile cell with a voltage of 3.7 V and a capacity of 2000 mAh — great for applications such as:

• flashlights,
• sensors and wireless devices,
• electronic toys,
• IoT devices,
• remote controls and controllers,
• as well as mobile DIY systems.

Its lightweight design and standard 18650 format make the cell easy to integrate into a wide range of builds — both commercial and hobbyist.

INR technology – stability and performance

The 18650 battery is manufactured using INR (LiNiMnCoO₂) technology , which ensures good current performance, safe operation in variable temperatures and a longer service life than traditional cells. Thanks to its stable operating voltage and low self-discharge, the battery remains fully operational even after prolonged storage.
