Questions about this item

How long will the 1400 mAh capacity actually run a Lectrosonics SSM transmitter?

Run time depends on the transmitter's power draw; the 5.18 Wh rating gives a baseline for comparing against the device's stated consumption.

Does the 3.7 V output match the original Lectrosonics LB-50 specification?

Yes, these cells are rated at 3.7 V, the same nominal voltage as the Lectrosonics LB-50 and 40117 packs they replace.

Will the 3 × 2 × 3 inch dimensions fit the IFBR1B bodypack receiver's battery compartment?

The pack is built to the LB-50 form factor, so it fits the SSM transmitter, IFBR1B receiver and IFBR1B bodypack receiver.
