Have used the Jungee 1.5V LiPo rechargeable AA batteries on my Hubsan H501S transmitter. But be cautioned that unlike normal 1.2V Ni-Mh rechargeable batteries, the drop of voltage on these 1.5V Li-Po is substantial and thus you may not be given much warning before the battery is depleted and unusable by your transmitter. In my case, it took <30s from the battery gauge on my transmitter drop a knob to completely turn off due to low voltage.
