My 2700 T&B receiver had been draining batteries constantly, but this one holds a charge through a full day of use without dropping. The 7.4V output feels solid and the connection to my headset is rock steady. Exactly what I needed for the expandable setup.
Fits perfectly into my 2300NCP expandable receiver—no fiddling with wires, just clicked in and powered right up. The 7.4V output feels stable so far, and it’s holding a charge well through multiple sessions.
I was a little worried about compatibility, but it paired perfectly with my 2300NCP EXPANDABLE after I checked the list. The 7.4V 500mA rating gives me a full day of use without any drop-off, which is exactly what I needed for my setup.
