I have a 4S2P Lithium-ion battery for my quadcopter. I'm charging it with the Imax B6. I would like to ask what would be the suggested charging current for the battery pack with the 4S2P setup? Thanks!

This question appears to be off-topic. The users who voted to close gave this specific reason:

The Imax B6 has maximum charging power of 50W. A 4S Li-ion/Lipoly battery charges to 16.8V (4.2V/cell), so the maximum current the charger can do is 50W/16.8V = 3A.
A battery rated to handle the current drawn by a quadcopter of a size suitable to carry it will almost certainly be rated for at least a 1C charge rate. Maximum charge rate = charge 'C' rating x battery capacity in Ah. At 1C charge current = battery capacity.
So the only question remaining is - what is the capacity of your battery? If it is greater than 3000mAh then set the charger to 3A. If it is less than 3000mAh then set the charger to the battery's capacity eg. 2.6A for a 2600mAh battery.
