Questions about this item

What comes in the Kastar LB-50 pack and do I need a separate cable?

The pack includes one AC wall charger with a foldable flat plug and four 3.7V 1400mAh lithium-ion batteries. No extra cable is required because the plug folds directly into a wall outlet.

Should I choose a different capacity or voltage for my Lectrosonics gear?

These batteries are 3.7V 1400mAh (5.18Wh) and are built as direct replacements for the Lectrosonics LB-50, SSM Transmitter, IFBR1B Receiver, IFBR1B Bodypack Receiver and part 40117. No other capacity or voltage is offered in this listing.

How long will a 1400mAh charge run my SSM transmitter in practice?

Each battery delivers 5.18Wh at 3.7V. The charger supplies 4.2V at 600mA, so a full charge takes roughly two to three hours. Actual transmitter run-time depends on the device's current draw, which varies by settings and RF conditions.
