Now I am sure that it would charge a 4S pack two cells at a time if you made an adapter however it is really one of those areas where if you have to ask then the answer is no.

Hey ive got a dumb question. where do yall plug these chargers in? do you hook it up to a car battery or does it come with an adapter with a wall plug. im about to get one and im not seeing a standard 115V plug.[sm=confused_smile.gif]

Very few chargers come with AC power capabilities built in ,most especially higher output ones.

You will need a AC to DC 12-15 volts power supply and it should be at least 12 amps. and more is always better.

A automotive battery will work however be advised that based on my rather extensive experience these batteries take approx. 2/3 (0.66) Ah per cell per charge, so a 3S pack takes 2Ah from a 12V deep cycle per charge.
Due to the way many 12v batteries are rated a 7Ah sealed type would do well to last two charges.
