Power Kit for Lumix S5 Shooters

This set delivers four lithium-ion cells and a dual-slot USB charger built for the Panasonic Lumix DC-S5 and DC-S5KK mirrorless cameras. It replaces the OEM DMW-BLK22 battery and DMW-BTC15 charger, giving video creators and event photographers enough capacity to keep shooting through long sessions without hunting for wall outlets.

Cool, Quiet Charging from Any USB Source

The LTD2 charger draws 5 V at up to 3 A through either Micro-USB or USB-C, then feeds each cell 4.2 V at 800 mA while an LCD panel shows real-time capacity. Two batteries charge side-by-side with no fan noise, and the 15 W input ceiling means a standard power bank or laptop port is sufficient for overnight top-ups.

Step Up From a Single Stock Battery

One bundled cell forces frequent swaps on the S5; this kit quadruples that reserve and adds simultaneous charging so depleted packs rotate back into service faster. The jump is worth it when a day’s work exceeds roughly 15.8 Wh per battery or when travel limits access to AC power for hours at a time.

Questions about this item

How do I install the Kastar BLK22 batteries into the LTD2 charger, and what step do people often miss?

Insert each battery into a slot until it clicks; the LCD then shows capacity. People forget to use a 5V 2-3A power source, so charging stalls at 800mA.

What maintenance or replacement will the Kastar BLK22 batteries need later?

Lithium-ion cells degrade after hundreds of cycles; expect shorter run-time from the 2200mAh capacity and replace the pack when it no longer holds a full 15.8 Wh charge.

What limit appears first during sustained charging of the Kastar BLK22 pack?

The charger outputs 4.2V at 800mA per slot, so two batteries charge simultaneously at that rate; total input is capped at 15W, making charger throughput the bottleneck.
