Can you suggest a rechargeable AA battery to use in Shure wireless devices?
Posted June 2016: iPower US has introduced a new AA rechargeable cell. It is a lithium-polymer design. This cell provides 1.5 Vdc through the entire operational time. There is no drop-off of the voltage.
Two iPowerUS AA cells last for 9 hours in a Shure QLXD1 bodypack.
