Three-Battery Kit for Canon EOS and PowerShot

This set includes three lithium-ion BP-511/BP-511A replacements and a compact LTD2 dual charger. Each cell delivers 7.4 V and 2600 mAh for 19.24 Wh capacity. The pack suits owners of EOS 5D, 10D, 20D, 30D, 40D, 50D, 300D, D30, D60, Kiss and Kiss Digital bodies plus PowerShot G1–G6, Pro 1, Pro 90 and Optura camcorders.

Dual-Slot USB Charger with LCD Status

The LTD2 unit accepts 5 V 2–3 A input through Micro-USB or Type-C and charges two batteries simultaneously at 8.4 V 800 mA each. An integrated LCD panel shows real-time capacity and charging progress for both slots. Interchangeable plates allow the same charger to handle other compatible BP-series cells.

Steady Output During Extended Shooting

Each 2600 mAh cell maintains the rated 7.4 V through long sessions without the voltage sag seen in lower-capacity packs. The charger’s 800 mA per channel replenishes a depleted pair in a predictable cycle, so spare batteries are ready for the next day of continuous capture.

Questions about this item

How do I install the BP-511A batteries into the LTD2 charger without inserting them backwards?

Align the battery contacts with the charger pins; the LCD shows a charging icon only when polarity is correct, so insert each pack until it clicks and verify the display lights up.

When will the 2600 mAh Li-Ion cells need replacement under normal use?

Expect roughly 300 to 500 full charge cycles before capacity drops below 80 % of the rated 19.24 Wh, at which point run-time noticeably shortens and a new pack is advisable.

What thermal limit appears first during prolonged dual-battery charging at 800 mA each?

The charger’s 15 W input rating is reached first; sustained dual output at 8.4 V 800 mA per slot pushes the 5 V 2-3 A supply to its ceiling, so the unit throttles or pauses if the source cannot maintain 15 W.
