Nitecore Intellicharger i4 2014 Version Lithium Ion IMR Smart Charger

This 4 Cell charger from Nitecore is an incredible value for someone with lots of batteries but not lots of cash!  The i4 Automatic Intelligent charger features four individual channels which each have their own three-color LED charge status display and automatic sensors to detect if the battery is Nickel Metal Hydride, Nickle Cadmium, Standard Lithium-Ion, or IMR Lithium.  Designed with vaporizers in mind, if an IMR High Rate cell is detected it optimizes the charge rate automatically.  Any battery detected automatically receives a three-stage charge with an automatic cutoff.  All of the features you expect from a smart charger are built-in, including:

• Auto-stop when battery charging is complete
• Over-charge protection
• Battery Cell Temperature Monitoring
• Fire Retardant / Flame Resistant ABS construction
• Reverse Polarity Protection
• Insured Worldwide by Ping An Insurance Group
