Ready-to-shoot kit

This set includes four LP-EL lithium-ion batteries and a dual-slot USB charger, giving Canon Speedlite EL-1 and EL-5 users enough spare power for extended sessions. Each cell delivers 7.2 V and 2600 mAh for a total of 18.72 Wh. The charger handles two batteries at once so downtime stays short.

Flexible charging anywhere

The LTD2 charger accepts Micro-USB or USB-C input at 5 V 2-3 A up to 15 W and outputs 8.4 V at 800 mA per slot. An LCD panel shows real-time capacity for both bays. Interchangeable plates let the same unit charge other battery types when needed. A Micro-USB cable is included in the box.

Cool quiet operation

Li-ion chemistry and the modest 800 mA charge current keep heat low during typical top-ups. No fan is present so the unit runs silently on a desk or in a bag. The 15 W input ceiling means it draws little power from standard USB ports or compact adapters.
