LiPo batteries don''t like staying at top voltage (4.2V rated, typically) "trickle charging," because this will metalize the lithium, which will kill the battery. However, it is safe to "float" a lithium polymer cell at a lower voltage -- typically somewhere between 3.9V and 4.05V, depending on the manufacturer and cell specifics.
