Compatible Power Kit

This kit includes four lithium-ion batteries and one dual-slot USB charger built for Lectrosonics LB-50 cells. Each battery delivers 3.7 V and 1400 mAh for a total of 5.18 Wh. The charger accepts Micro-USB or Type-C input at 5 V 2-3 A and can charge two packs simultaneously at 4.2 V 800 mA per slot.

Audio Field Professionals

Sound mixers and boom operators who run Lectrosonics 40117, SSM transmitters or IFBR1B bodypack receivers will appreciate the hot-swap convenience and LCD charge readout. The bundle is not suited for users of other battery formats or for productions that require higher-capacity cells.

Dual-Slot USB Charging

The decisive spec is the charger’s ability to replenish two LB-50 batteries at once from any 5 V USB source. If your workflow demands single-bay charging only, a simpler adapter would suffice.
