Replacement Battery & Charger for Lectrosonics LB-50

This pack supplies a Kastar lithium-ion cell and a matching AC wall charger built for Lectrosonics LB-50, SSM Transmitter, IFBR1B Receiver, IFBR1B Bodypack Receiver and 40117 devices. It is aimed at audio professionals who need a direct replacement power source for those specific units.

AC Wall Charger Input Range and Output

The included charger accepts AC 100 to 240 volts at 50 to 60 hertz and delivers DC 4.2 volts at 600 milliamps. A foldable flat plug aids storage, while a red LED shows charging and a green LED shows standby or full charge. Buyers needing a multi-bay charger or a different voltage output must look elsewhere.

1400 mAh Lithium-Ion Cell Capacity

The battery provides 3.7 volts and 1400 milliampere-hours, equating to 5.18 watt-hours of energy. That single figure determines whether the runtime meets the demands of a Lectrosonics SSM Transmitter or IFBR1B Receiver during a session.

Questions about this item

Is the 1400 mAh LB-50 the only capacity option in this pack?

Yes, the pack contains a single 3.7 V 1400 mAh lithium-ion cell rated at 5.18 Wh.

What does the 5.18 Wh rating mean for runtime in a Lectrosonics SSM transmitter?

It indicates the total energy the battery can deliver; actual operating time depends on the transmitter’s power draw.

How does the AC 100–240 V input and DC 4.2 V 600 mA output affect charging speed?

The charger supplies up to 600 mA at 4.2 V, so a full charge from empty takes roughly two to three hours.
