you could probably use the wall charger, but once again, you would have to rig some sort of device to know when the battery was at capacity. there are a couple of people that frequent my store that have made such devices from parts from radioshack. but use at your own risk if your not sure what you are doing. and maybe try it on a cheap lipo, and not an expensive one. the way a lipo charges is buy charging one cell fully and then moving on to the next one and so forth until all cells in the packs are charged. but on the new generation of TP lipos they give you the extra wires to charge each cell independently, just like on some Tanic packs and other higher end lipos. I spoke of constant current being used to charge the lipos, lipos also discharge in this manner, that is why they have no memory like other batterys. and on that same note, that is why they are the favorite batteries for brushless motors. the constant current is a good match for the way that a brushless motor is actuated by the brushless speedcontrol. because unlike a brushed motor the speed is not varied by how many volts you put into it.
