18650 4-Channel Standard Charger: Efficient Charging for 18650 Lithium Batteries
Product Introduction
The 18650 4-Channel Standard Charger is a specialized charging solution engineered for single 18650 ternary lithium batteries. Designed to deliver 4.2V precision charging with dual – current modes (0.5A standard, 1.0A fast), this charger integrates a microprocessor for multi – stage charging (pre – charge, constant current, constant voltage, stop charge) and advanced battery maintenance. Built with a rugged aluminum alloy shell (brown – green GY05) for natural heat dissipation, the 4-Channel 18650 Standard Charger meets military – grade standards (GJB151B – 2013/GJB150A – 2009) and operates reliably in extreme temperatures (-40℃~+55℃).
