A Battery Charger performs the voltage equalizing and state of charge among the cells when they are at a full charge. The 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.B3-AC Lipoly Battery Charger is a simple to use charger for 2S and 3S battery packs. There is no need for extra power sources or 12v batteries with this charger because it has its own built-in power supply that can be supplied by 100-240v.
The B3-AC is a user-friendly battery charger. Built-in JST-XH balance plug connectors and three LEDs show charge status on the IMAX B3-AC Charger. The three LEDs in the charger will turn green when we just connect it into the wall outlet. The Red LED flashes when the charger is ready. Connect the battery’s balance lead to the charger’s balance port, and the charger will identify the battery’s voltage and begin charging after 2 seconds. When the LEDs are turned on, they will shine a steady red.
If the battery is two-cell, the cell LED indications 1 and 2 will shine continuously; if the battery is three-cell, the cell 3 LED indicator will also glow. When a cell is entirely charged, the associated LED turns green, indicating that the battery is fully charged. When all cells light green, the battery is fully charged. Before turning off the charger, be sure the battery is disconnected. The charger’s high-precision balancing circuit can deliver a higher current of up to 850mA.
