7.4 11.1V LiPO Lithium Battery Charger

The LK-1008A Intelligent LiPo Balance Charger is a compact and user-friendly charging solution designed specifically for 2-cell (2S, 7.4V) and 3-cell (3S, 11.1V) lithium polymer (LiPo) and lithium-ion (Li-ion) batteries commonly used in RC hobbies, drones, and DIY electronics. Unlike basic battery chargers, this unit features a balance charging function, which is critical for the longevity and safety of multi-cell lithium batteries. Balance charging ensures that each individual cell within the battery pack is charged to the same voltage level, preventing cell imbalance that can lead to reduced battery life, damage, or even dangerous thermal events. The charger includes intelligent automatic voltage detection with an impressive accuracy of 0.01V, and an automatic cut-off function that stops charging as soon as the battery is fully charged, preventing overcharging. Multiple LED indicator lights provide clear visual feedback about the battery's current charge status during the charging process. Safety is paramount in any lithium battery charger, and the LK-1008A comes equipped with essential protections including over-charge protection and short-circuit protection, giving users peace of mind during unattended charging sessions. The charger accepts a DC input voltage between 11V and 15V (making it compatible with standard 12V power supplies and car batteries via the detachable crocodile clips), and delivers a balanced output current of 800mA to the connected battery. Its compact dimensions (75 × 50 × 25mm) and lightweight design (only 39 grams) make it highly portable—perfect for charging batteries at the field, in the workshop, or at home.
