WATTNINE 16.8V 2A Wall Mount 4S Li-ion / LiPo Battery Charger with CC/CV

The WATTNINE 16.8V 2A Wall Mount 4S Li-ion / LiPo Battery Charger with CC/CV is a reliable and efficient charger for 4-cell (4S) Li-ion and LiPo battery packs. It uses Constant Current / Constant Voltage charging, which first charges at a fixed current and then maintains a stable voltage to safely complete charging. This ensures fast, balanced charging, extends battery life, and protects against overcharge and overcurrent.
