The LiitoKala Lii-S12 is a high-capacity universal charger that combines advanced functionality with unparalleled convenience for users who demand efficiency and safety. This 12-slot charger stands out for its ability to independently manage and charge multiple types of rechargeable batteries, making it an ideal solution for a wide range of applications, from high-capacity lithium-ion cells to everyday NiMH and NiCd batteries.

The Lii-S12 is equipped with an intelligent microcomputer management system that ensures each slot operates independently. This means you can charge a variety of battery types and sizes simultaneously without any risk of interference. The charger supports a broad spectrum of batteries, including large formats like 32650 and 26650 cells, mid-sized options like 18650 and 21700 batteries, and smaller NiMH batteries such as AA and AAA. This versatility is a major advantage for users who rely on a mix of devices, from flashlights and cameras to household electronics and power tools.

One of the defining features of the Lii-S12 is its auto-polarity detection capability. This smart function eliminates the need for manual orientation of batteries, simplifying the charging process and reducing the risk of errors. Coupled with an impressive input power of 12V/3.5A and a total output of 48W, the charger efficiently handles demanding power needs. Whether charging a single battery or utilizing all 12 slots, the Lii-S12 ensures a consistent and reliable performance.

The Lii-S12 features an intuitive LCD display that provides real-time information about the charging process. Users can monitor essential parameters such as battery type, charging current, voltage, and progress percentage. Each slot is equipped with its own indicator light, with red signaling active charging and green indicating completion. If a problem arises, such as a short circuit or reverse polarity, the charger displays an error code (Err) on the LCD and flashes the corresponding red light, ensuring users are promptly alerted to any issues.

With its ability to automatically identify battery chemistries, the Lii-S12 is incredibly user-friendly. It recognizes lithium-ion batteries (3.7V and 3.8V), lithium iron phosphate (LiFePO4) batteries (3.2V), and NiMH/NiCd cells (1.2V). For users who require additional flexibility, the charger allows manual selection of specific battery types via the MODE button, enabling precision charging for specialized batteries.

The charging current is intelligently managed based on the number of batteries inserted. When all 12 slots are in use, the charger delivers 0.5A per slot. With fewer batteries, the current is adjusted to 1.0A for faster charging. This adaptability ensures optimal performance without compromising the longevity of the batteries.

The Lii-S12 also includes a range of safety features designed to protect both the charger and the batteries. These include overcharge protection, over-discharge protection, short circuit prevention, and reverse polarity safeguards. Additionally, the charger features a temperature protection system that automatically adjusts the output current if the device exceeds 55°C, maintaining an optimal operating temperature and enhancing the user experience.

The 0V activation function is another standout capability of the Lii-S12. This feature revives deeply discharged batteries, a common issue with older or improperly stored cells. The charger provides a small trickle current to safely restore these batteries, ensuring they can be reused and extending their lifespan.

Constructed from durable materials, the Lii-S12 is built to withstand regular use while maintaining high performance. Its sleek design and compact footprint make it easy to integrate into any workspace or charging station. The ergonomic layout of the slots and buttons ensures seamless operation, even for users new to multi-slot chargers.

In addition to its technical capabilities, the Lii-S12 is compatible with an extensive range of battery formats. From lithium-ion batteries like 26650, 18650, and 14500 to NiMH and NiCd cells in AA, AAA, and SC sizes, this charger meets the needs of both hobbyists and professionals. The support for 9V rechargeable batteries further broadens its application, making it a versatile tool for various devices.

Overall, the LiitoKala Lii-S12 combines cutting-edge technology with ease of use, making it a top choice for anyone requiring a reliable and versatile charger. Its ability to handle multiple battery types, coupled with robust safety features and an informative display, ensures a seamless charging experience. Whether for personal use or professional applications, the Lii-S12 offers exceptional value, delivering efficient and safe charging for all your battery needs.
