Four-pack Li-ion replacement for Lectrosonics gear

This set contains four Kastar LB-50 lithium-ion batteries rated at 3.7V and 1400mAh each. They are designed to replace the original Lectrosonics LB-50 cells used in SSM transmitters and IFBR1B bodypack receivers.

Direct swap with built-in protection circuits

Each cell delivers 5.18 Wh and includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards. The pack fits the existing battery compartment without modification and meets UL1642 and CE safety standards.

Suits sound crews needing multiple spares

Ideal for production teams running several Lectrosonics 40117-compatible units who want a ready supply of tested replacements. Not suited for devices requiring a different voltage, form factor or proprietary communication protocol.

Questions about this item

How long will one 1400 mAh pack run a Lectrosonics SSM transmitter before it needs recharging?

Run-time varies with the transmitter's current draw; the pack stores 5.18 Wh at 3.7 V so divide that by the device's watts to estimate hours.

Do the cells stay cool and quiet during all-day use in an IFBR1B bodypack?

Lithium-ion chemistry produces no fan noise and the built-in protection circuit limits over-heating, so temperature rise stays modest in normal operation.

What charger do I need for these LB-50 packs?

They require a charger made for 3.7 V lithium-ion cells; the original Lectrosonics charger or a compatible third-party unit with the same voltage will work.
