Three batteries and one charger

This pack contains three lithium-ion cells rated at 3.7 volts and 1400 milliampere-hours each, plus a single AC wall charger. It is built for owners of Lectrosonics SSM transmitters, IFBR1B receivers or bodypack receivers that use the LB-50 battery. The kit replaces original part 40117 and supplies spare power for location sound work.

Charger runs from any mains voltage

The wall unit accepts 100 to 240 volts AC at 50 or 60 hertz and delivers 4.2 volts DC at 600 milliamps. A red LED shows charging; green shows standby or full charge. The foldable flat plug keeps the outline slim for travel bags. Each cell stores 5.18 watt-hours, so the charger can top up a depleted pack in a few hours.

Only fits Lectrosonics LB-50 devices

The batteries and charger are electrically matched to the LB-50 platform and will not operate with other voltages, chemistries or form factors. Buyers who need a different voltage, a higher capacity or a multi-bay charger must look elsewhere.

Questions about this item

Does the LB-50 charger get hot or draw much power when left plugged in all day?

The charger draws AC 100~240V at 50~60Hz and outputs DC 4.2V 600mA, so its idle draw is very low and it stays cool during continuous use.

What equipment must I already own for these LB-50 batteries to work?

You need a Lectrosonics device that accepts the LB-50 battery, such as the SSM Transmitter, IFBR1B Receiver, IFBR1B Bodypack Receiver or 40117 unit.

Will the Kastar LB-50 pack work alongside my original Lectrosonics LB-50 cells without mismatch?

Yes, each battery is 3.7V 1400mAh 5.18Wh, matching the original Lectrosonics LB-50 specification, so they can be mixed in the same device.
