This battery adaptor is specially designed for providing DC power for Panasonic monitors BT-3DL2550 and BT-LH2550 using ENDURA batteries. IDX strongly recommends using models ELITE, E-HL9 or E-HL9S for this application. The A-E2BT24V installs easily onto either monitor's VESA100 mount area using supplied screw set and attaching the hardwired XLR connector to the monitor. This mount can be installed either vertically or horizontally. For additional flexibility, add the optional A-E241E onto the A-E2BT24V and double the battery capacity for longer run times.
