Features: There are three levels of charging current: 0.5A/1.0A/2.0A, the default charging is 0.5A, you can long press the corresponding button to select the charging current. There are multiple safety for protection functions such as overcharge, overdischarge, short circuit, etc. At the same for time, it can intelligently and automatically identify bad batteries. It can automatically identify lithium battery (Li-Ion 3.70V) battery and nickel-metal hydride (Ni-MH) battery, and manually select lithium iron phosphate battery (3.20V) and Li-Ion 3.85V battery. Adopt DC12V1A (nominal) input, two-slot independent charging and microcomputer management system; the biggest highlight of this charger is that it can charge the battery regardless of polarities! When charging, the LCD can display channel and the charging current, voltage, for time, capacity and battery type Li-Fe 3.20V /Li-ion 3.70V /Li-ion 3.85V (IMR); the total charging current of the two slot No more than 2A, that is, when one of slot is charge with 2A current, and then the battery is charge in another slot, the front 2A current will fall back to 1A current for charging; when the battery is fully charge, the LCD will display FULL.
