LiitoKala Lii-S12 12-Slot LCD Charger for 26650 18650 NiMH NiCd LiFePO4 9V Batteries

The Lii-S12 from LiitoKala is a dedicated 12-slot battery charger designed to handle multiple chemistries and sizes simultaneously. Whether you manage a collection of 18650 cells for vapes or flashlights, need to charge NiMH AA batteries for household devices, or use 9V rechargeables for professional equipment, this charger consolidates your charging tasks into one efficient unit. Each slot features its own LCD screen, so you can check charging status at a glance without guessing. The included DC 12V/3.5A power adapter supports either EU or US plug standards, making it suitable for home or workshop use.

Charging Capabilities and Compatibility

The Lii-S12 accepts a wide range of rechargeable battery sizes and chemistries, reducing the need for multiple single-format chargers.

Battery Chemistries Supported

It charges Li-ion (output 4.2V), NiMH/NiCd (1.48V), LiFePO4 (3.65V), and 9V NiMH (9V). This covers most common rechargeable battery types used in consumer electronics, power tools, and portable devices.

Battery Sizes Accepted

Compatible sizes include 26650, 21700, 20700, 18650, 18490, 17700, 17500, 16340 (RCR123), 14500, 10440 for cylindrical lithium cells, plus NiMH/NiCd sizes AA, AAA, A, SC, C, and 9V. This range covers everything from small 10440 cells to large 26650 batteries.

Charging Current Details

For lithium batteries, the charging current is 1000mA per channel on channels 1, 3, 5, 7, 9, and 11 (six channels total). NiMH batteries charge at 500mA across eight slots. The 9V battery slots provide 85mA each for two batteries. This segmentation allows mixed charging of different chemistries within the same charger.

Design and Build

The charger is built to be both functional and space-efficient for regular use.

Physical Dimensions and Layout

The unit measures approximately 28.7 cm by 14.3 cm by 3.5 cm, with a black finish that suits a workbench or shelf. The 12 slots are arranged in two rows, each with its own LCD panel for independent status monitoring.

Included Accessories

Each purchase includes the Lii-S12 charger, a 12V/3.5A power adapter (available in EU or US plug standard), and a user manual written in English, Chinese, and Russian. The manual provides clear instructions for connecting the power adapter and inserting batteries correctly.

Safety and Convenience Features

Individual slot control means you can charge batteries of different types and capacities at the same time without affecting each other. The LCD displays show charging status per slot, helping you quickly identify which batteries are ready.

Practical Usage Scenarios

The Lii-S12 suits both regular home users and professionals who maintain multiple rechargeable batteries.

Home and Hobbyist Use

For photo enthusiasts, this charger can handle 18650 or 14500 cells for camera flashes or torches. For families, it can charge AA and AAA NiMH batteries for remote controls and toys in one batch.

Professional and Workshop Use

Anyone working with 26650 or 20700 cells for high-drain devices can benefit from the dedicated lithium charging channels. The 9V charging capability also supports professional microphones or measuring instruments.

Mixed Chemistries Simultaneously

Because each slot is independent, you can charge Li-ion, NiMH, and 9V batteries all at the same time, making it a versatile tool for any battery management setup.

Buying Considerations

When choosing a multi-slot charger, reliability and clear status indication matter.

Why Choose the Lii-S12

Its 12-slot capacity with individual LCDs and support for four chemistries covers a broad range of battery types without needing separate chargers. The included 12V adapter and multilingual manual make setup straightforward.

Low Maintenance Benefits

Using a dedicated charger helps maintain battery performance by applying the correct charging profile for each chemistry. The separate current settings for lithium and NiMH prevent overcharging issues when mixing batteries.

Summary

For anyone needing to charge multiple rechargeable batteries of different sizes and chemistries, the LiitoKala Lii-S12 provides a practical, all-in-one solution with individual slot control and clear LCD feedback.
