High-Performance Lithium Ion (Li-ion) & Polymer Battery Chargers
Lithium-Ion and Lithium-Polymer cells are the premier power chemistry for modern electronic systems, prized for their superior energy density, light weight, and long cycle life. To unlock maximum operational longevity while eliminating safety hazards, Li-ion chemistry requires precise charging control engineered to strict voltage and thermal thresholds.
Every Cell-Con Lithium Ion battery charger incorporates a sophisticated Constant Current / Constant Voltage (CC/CV) charge algorithm. Final charge termination automatically triggers when the charging current drops below a designated threshold (current detection mode) or upon the completion of a safety timer. The optimal charge termination method is selected based on your OEM battery pack specifications, cell chemistry, and mission-critical operating requirements.
