Specially Designed for Lithium Batteries: The 12V 20A battery charger is engineered for 12V lithium batteries, featuring a 3-stage charging mode (pre-charge phase, constant current phase, and constant voltage phase). Compact Size & Lightweight Design: Utilizing advanced LLC resonance technology with optimized structure and thermal management, this charger boasts an ultra-compact profile (L205 x W100 x H550mm) and lightweight build (1.10kg), ensuring easy portability. Lithium Reactivation: When protected by a BMS, this LiFePO4 charger can reactivate over-discharged LiFePO4 batteries and restore them to normal voltage levels. Multi-Layered Protection: Equipped with 3 built-in safety mechanisms—overheat protection, output short-circuit protection, and output overvoltage protection. A blinking red LED indicates the activation of protection mode due to charging errors. Effortless Operation: Achieve instant connectivity via plug-and-play Anderson connectors, seamlessly linking your lithium battery to the WattCycle 12V 20A smart battery charger.
