Compatible power kit for Lectrosonics gear

This set supplies a 1400mAh lithium-ion cell rated at 3.7V and 5.18Wh together with an LTD2 dual-slot USB charger. It replaces the Lectrosonics LB-50 battery and works with 40117, SSM transmitter, IFBR1B and IFBR1B Bodypack receiver units.

Check device model and USB power source

Verify that your equipment accepts the LB-50 form factor before ordering. The charger requires a 5V 2-3A 15W USB supply via Micro-USB or Type-C input; a Micro-USB cable is included. Each slot delivers 4.2V at 800mA whether one or two cells are inserted.

Suits audio pros needing spare cells on location

Ideal for sound mixers and boom operators who want a lightweight backup that charges from common USB power banks. Not for users who need higher-capacity packs for all-day shoots without recharging, or teams requiring a multi-bay dock for more than two cells at once.

Questions about this item

What comes in the box and do I need to buy a power adapter separately?

The package includes one LB-50 1400 mAh lithium-ion battery, the LTD2 dual-bay USB charger and a Micro-USB cable. A 5 V 2-3 A USB power adapter is not included and must be purchased separately.

Should I choose the single-battery pack or a multi-pack for the Lectrosonics LB-50?

This listing is a single pack containing one battery and one charger that can charge two batteries simultaneously. If you need a spare, you can buy additional LB-50 batteries separately and charge both in the same LTD2 unit.

What does the 5.18 Wh rating mean for runtime in my Lectrosonics 40117 or SSM transmitter?

At 3.7 V and 1400 mAh the cell stores 5.18 Wh. The charger delivers 4.2 V at 800 mA per bay, so a full charge takes roughly two hours and typical transmitter run-time matches the original Lectrosonics LB-50 specification.
