Battery and dual charger kit

The Kastar LP-EL pack pairs a 7.2V 2600mAh lithium-ion cell with an LTD2 charger that can handle two batteries at once. It replaces the Canon LP-EL and 4307C002 packs for Speedlite EL-1 and EL-5 units. Photographers who need a ready spare for long shoots get a matched set in one box.

Thermals, noise and power draw

The charger draws up to 15W from a 5V 2-3A source and delivers 8.4V at 800mA per slot whether one or two cells are inserted. No fan is present so operation is silent. Typical warmth stays low during a full charge cycle.

Bundled accessories and software

A Micro-USB cable is included and the charger accepts both Micro-USB and Type-C inputs. Swappable plates let the same dock charge other battery types. An intelligent LED display shows real-time capacity and charging status for each slot.

Questions about this item

How do I install the LP-EL battery into my Canon Speedlite EL-1 and what step do people often miss?

Slide the LP-EL pack into the flash until it clicks, then attach the flash to the camera hot shoe; the step often missed is ensuring the battery latch fully engages before mounting.

What maintenance or replacement will the LP-EL 2600mAh battery need over time?

The lithium-ion cell will gradually lose capacity after hundreds of charge cycles; plan to replace the pack when runtime drops below your shooting needs.

What limit appears first when using the LTD2 charger continuously for multiple batteries?

The charger outputs 800mA per slot, so charging two 2600mAh packs together takes longer than a single pack and the 15W input becomes the bottleneck.
