Stop charging multi-cell packs two or four slots at a time. The LiitoKala Lii-S12 12+2 Bay Smart Universal Charger provides a massive 48W powerhouse designed to safely manage, test, and charge up to 14 individual cells simultaneously. Equipped with a central microcomputer processing system, every single one of the 12 cylindrical slots operates on an entirely independent railallowing you to mix and match lithium-ion, NiMH, and LiFePO4 chemistries in the same session without cross-interference. Plus, it features two dedicated 9V square battery ports, making it the ultimate command station for robotics developers, drone operators, and field technicians.
Patented Auto-Polarity Detection: Never worry about dropping a cell in backward again. The 12 primary cylindrical slots automatically detect positive and negative orientation instantly, protecting your gear while streamlining rapid swap outs.
14-Channel Hybrid Architecture: Houses 12 high-clearance multi-diameter bays alongside 2 integrated 9V NiMH charging terminals (85mA * 2) right on a single compact footprint.
Intelligent Dynamic Amperage Scaling: Automatically scales charge rates based on load context. Drops down to a safe, temperature-controlled 0.5A when loaded across all 12 bays, or ramps up to a fast 1.0A charging rate on odd slots (1, 3, 5, 7, 9, 11) for quick turnarounds.
Smart Backlit LCD Display: Cycles through vital performance logs per channel, displaying real-time battery chemistry type, current capacity percentage, precise voltage curve (V), and internal charging current (A).
Hardware-Level 0V Cell Activation: Built-in rescue circuitry safely applies a delicate trickle current to wake up over-discharged or sleeping Lithium cells that standard protective chargers flag as dead or broken.
