Guys:

Recently purchased two 2 cell 3.000 mah and one 4cell 4,000 mah batteries for two new projects, both without any experience with the intended systems. The two cell batteries simply do not have the voltage to do the job, so I would like to have them re-configured into one 3 cell 3,000. The 4 cell is simply too heavy for the airframe. Can it be re-configured into one 3 cell pack? Would not normally bother, but these are new packs, the 4,000 never charged and I see no future use for them. Can I send them in and get them fixed ? Thanks
