Two-pack Li-Ion replacement for Lectrosonics LB-50

This pack contains two Kastar LB-50 lithium-ion batteries rated at 3.7 V and 1400 mAh each, delivering 5.18 Wh per cell. They are built as direct replacements for the original Lectrosonics LB-50 power source used in SSM transmitters and IFBR1B receivers.

Verify your device uses the LB-50

Confirm that your transmitter or bodypack receiver lists the LB-50 battery or Lectrosonics part number 40117 in its specification. The cells measure 3 by 2 by 2 inches, so check the battery compartment dimensions against that footprint. Ensure the equipment accepts a 3.7 V lithium-ion pack with built-in protection circuitry.

Suits audio professionals needing spare packs

Ideal for sound crews who run SSM transmitters or IFBR1B bodypack receivers and want extra runtime between charges. Not suited for users whose equipment requires a different voltage, chemistry or form factor, or for anyone needing a charger included in the package.

Questions about this item

Does the 2-pack include a charger or only the two LB-50 batteries?

The pack contains two 3.7 V 1400 mAh lithium-ion LB-50 batteries; no charger is included.

Should I choose the single LB-50 or the 2-pack for my Lectrosonics SSM transmitter?

The 2-pack gives you a spare 5.18 Wh cell so the transmitter can keep running while one battery recharges.

What does the 5.18 Wh rating mean for real-world run time in an IFBR1B receiver?

At 3.7 V and 1400 mAh the cell stores 5.18 Wh, typically powering the receiver for several hours before needing a recharge.
