Replacement power for Lectrosonics gear

The Kastar LB-50 kit supplies two lithium-ion batteries and an AC wall charger compatible with Lectrosonics LB-50, SSM Transmitter, IFBR1B Receiver, IFBR1B Bodypack Receiver and part 40117. Each cell delivers 3.7 V, 1400 mAh and 5.18 Wh. The charger accepts 100–240 V input and provides 4.2 V at 600 mA with red and green LED status lights. A foldable flat plug keeps the unit compact for travel.

Upgrade from single OEM cells or dead packs

Swapping a single factory battery for this twin-pack doubles available runtime and adds a dedicated wall charger so you no longer need the original docking station. The jump is worth it when a shoot day exceeds one battery cycle or when the original charger is lost, damaged or tied up in another kit. The universal AC input also removes the need for a separate travel adapter on international jobs.

Suits location sound teams and multi-day shoots

Audio engineers running Lectrosonics SSM transmitters or IFBR1B receivers on consecutive days will appreciate the ready spare and standalone charger. Users who only need a single replacement cell or who prefer charging inside the transmitter via USB should look elsewhere, as this kit is built around a two-battery, wall-powered workflow.

Questions about this item

Will the charger plug into a standard UK socket?

The charger accepts AC 100~240V 50~60Hz input, so it works on UK mains voltage with a suitable travel adapter.

How do I know when each LB-50 battery is fully charged?

Insert a battery into the charger; a red LED means charging, and a green LED means the 1400mAh cell is full.

When should I replace the two LB-50 batteries?

Replace them when run-time in your Lectrosonics SSM transmitter or IFBR1B receiver drops noticeably below the rated 5.18 Wh capacity.
