LiitoKala Lii-25R 18650 2500mAh Battery

Liitokala Lii-25R 18650 2500mAh is a high-current 18650 form-factor lithium-ion battery from the Liitokala brand, combining significant real capacity and stable current output. This power cell belongs to the category Power Independence > Rechargeable Batteries and is designed for applications with increased power consumption.

Lii-25R batteries are positioned as analogs to popular LG HE4 and Samsung 25R cells: they are similar in characteristics but have their nuances. In comparative tests between Samsung 25R and Liitokala Lii-25R, a slight difference was found: in some measurements, the real capacity of Liitokala not only matches the declared capacity but even exceeds expectations in certain tests. Specifically, test results showed a real capacity within 2550–2650 mAh, and some comparisons noted values of 2600–2650 mAh. Due to slightly higher internal resistance, these batteries demonstrate a somewhat lower continuous current output compared to some competitors — up to 15 A under constant load.

Thanks to the combination of high capacity and decent current output, Liitokala Lii-25R 2500mAh batteries are excellent for repacking power tool batteries (drills, grinders, screwdrivers), as well as for assembling battery packs in electric vehicles, robot vacuum cleaners, powerful flashlights, and other energy-intensive devices.

Please note: 18650 Lii-25R 2500mAh batteries are supplied without a built-in protection board (without PCM/PCB). It is recommended to use them in devices or assemblies that have their own protection against overcharge and deep discharge.
