Nitecore's Q4 Quick Charger is capable of charging up to 4 Li-ion batteries independantly (such as the LG HG2 / Samsung 25R *sold separately). Appropriate charging current and modes are automatically detected and adopted and has an optimized IMR charging system that ensure the end voltage is within safe limits. Nitecore has made the Q4 safe with overcharge prevention (light will turn green), as well as reverse polarity and short circuit preventions (red light will flash to make the user aware). Recharge depleted Li-ion batteries, the Q4 will test and activate the battery before charging. Top that all off with flame retardant and fire resistant material.
