QUOTE(zeroglyph @ Oct 25 2016, 12:58 PM) li-ion is 3.7v nominal. alkaline is 1.5v nominal. they are not the same. depends on what the transmitter required. general rule, more voltage than required = boom!. the reason i got this idea is because the controller got 1 usb port which able to charge up the helicopter.. im thinking if im using bigger mah battery on the controller, then im able to charge the helicopter more... but, dono isit workable..  |
