B3AC: Smart Balance Charger for 2S (7.4 volt) and 3S (11.1 volt) Li-PO (lithium Polymer) R/C batteries. The B3AC can be operated from a common wall outlet. Plug your battery's bala nce connector (the one with 3 or 4 wires) into the B3AC; the charger does a quick analysis of the battery, and then starts the smart balance-charging regimen. The charging rate averages to about 800mA per hour, per cell. The LED lights on the charger keep you appraised of how each individual battery in the pack is progressing. The B3AC is fully automatic, and shuts off when battery is full. Charge time depends on inherent battery capacity. The B3AC applies a separate individual charge to each cell in your battery pack. The B3AC is recommended for battery capacities ranging from 800mAh to 3600mAh. For smaller batteries, we can recommend the CoolCharger A3.For larger 2S & 3S batteries, we recommend the B3-20W.
