The Nitecore i2 is able to automatically identify Li-ion, LiFePO4, Ni-MH and Ni-Cd rechargeable batteries and apply the appropriate charging mode: Constant Current (CC), Constant Voltage (CV), or Trickle Charge.
Each battery bay has its own micro processor that is capable of monitoring and charging batteries independently.

As with the original i2, all you have to do is insert the 18650 battery into the slot and the new i2 will automatically detect and charge.
Compact and Compatible
The New Nitecore Intellicharger i2 is a compact device that can charge batteries that are 30mm to 69.3mm long, including flat top types. Super long batteries like some protected 26650 cells might not fit into the i2 bay.
The Nitecore Intellicharger i2 is compatible with IMR, Li-ion, LiFePO4, Ni-MH, and Ni-Cd batteries. It is capable of charging two batteries simultaneously.
