A Battery Charger performs the voltage equalizing and state of charge among the cells when they are at a full charge. The IMAX B3-AC Lipoly Battery Charger is a simple and compact advanced charger, able to charge, balance, and discharge LiPoly batteries. These can balance individual cells up to 3 lithium cells. IMAX B3-AC Lipoly Battery Charger is a simple to use charger for 2S and 3S battery packs. In this charger, there is no need for any additional power supplies or 12v batteries as it consists of its own built-in power supply that can be powered with 100-240v.
The IMAX B3-AC is a very easy to use battery charger. IMAX B3-AC Charger consists of built-in JST-XH balance plug ports and 3 LEDs to indicate charge status. When we simply plug it into the mains power, the 3 LEDs in the charger will light green. As soon as the charger is ready, the Red LED flashes. Now connect the balance lead of your battery to the balance port of the charger, and after 2 secs the charger detects the voltage of the battery and starts charging. The LEDs will glow to constant red when the charger starts charging.
The cell LED indicators 1 and 2 will glow constantly if the battery is two-cell, if it is a 3 cell then the cell 3 LED indicator will also glow. When a cell is completely charged the corresponding LED will turn green, when all cells turn green indicates that the battery is fully charged. The battery should be disconnected before switching off the charger. The high precision balance circuit in the charger is capable of supplying a larger current up to 850mA.
