Kastar 3-Pack LB-50 Battery Kit

This kit supplies three lithium-ion batteries and a dual-bay USB charger for Lectrosonics LB-50 compatible devices. It targets audio professionals using Lectrosonics 40117, SSM transmitters, or IFBR1B bodypack receivers who need reliable spare power on location.

Thermals, Noise and Power Draw

The charger operates from a 5 V 2–3 A USB source with a maximum 15 W input and delivers 4.2 V at 800 mA per bay when charging two cells simultaneously. No active cooling is present, so the unit runs silently and generates minimal heat during normal charging cycles.

5.18 Wh Capacity Per Cell

Each battery provides 3.7 V and 1400 mAh for a total of 5.18 Wh, which determines runtime for compatible Lectrosonics gear. Buyers who need higher capacity per cell or a different voltage platform should look elsewhere.

Questions about this item

How do I install the LB-50 batteries into the LTD2 charger and what step do people often miss?

Align each battery with the charge plate contacts, slide it in until it clicks, then connect the charger via Micro-USB or Type-C to a 5 V 2–3 A source; the step users miss is confirming the LCD shows the charging icon for each slot before walking away.

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

Lithium-ion cells degrade with cycles; expect to replace the 3.7 V 1400 mAh packs when run-time drops below roughly 80 % of the original 5.18 Wh capacity, typically after several hundred full charges.

What limit appears first during sustained charging of two LB-50 batteries on the LTD2 charger?

The charger’s 800 mA per-slot output caps the charge current, so two batteries draw the maximum 15 W input simultaneously; thermal throttling or the 4.2 V termination voltage will be the first limit you hit under continuous use.
