Compatible LB-50 Power Kit

This set includes two 1400 mAh 3.7 V lithium-ion batteries and an LTD2 dual USB charger. It replaces the Lectrosonics LB-50 and part 40117 for SSM transmitters and IFBR1B receivers. The charger powers both cells simultaneously from a 5 V 15 W source.

Who This Suits and Who It Does Not

Audio professionals using Lectrosonics bodypack gear who need spare cells and a compact charging solution will benefit. Buyers who require higher capacity cells or a charger with more than two bays should look elsewhere.

Deciding Specification: 1400 mAh Capacity

Each battery stores 1400 mAh at 3.7 V for 5.18 Wh total energy. The dual charger delivers 4.2 V at 800 mA per slot. Match these figures to your device's runtime and charging needs before purchasing.

Questions about this item

How do I install the batteries in the LTD2 charger and what step is often missed?

Slide each LB-50 pack into a slot until it clicks, then connect the charger via Micro-USB or Type-C to a 5 V 2–3 A source; the LCD will only show status after power is applied.

What maintenance or replacement will the LB-50 packs need over time?

Lithium-ion cells lose capacity with age; when run-time drops noticeably, replace both 1400 mAh packs together for balanced performance.

What limit appears first during sustained charging of both batteries?

The charger outputs 800 mA per slot, so two flat 1400 mAh packs need about two hours before the 4.2 V cutoff stops the current.
