Three-pack Li-ion batteries and dual USB charger

This set includes three 7.4 V 2600 mAh lithium-ion cells and an LTD2 charger that powers two batteries at once. It replaces Canon BP-511 and BP-511A packs for a long list of EOS, PowerShot, Optura and ZR cameras. The bundle suits photographers who need several spares for a full day of shooting.

Passive cooling and USB power input

The charger draws 5 V at up to 3 A through Micro-USB or Type-C and delivers 8.4 V at 800 mA per slot. No fan is fitted, so operation stays silent while the LCD shows charge level and status for each cell. Total input power is rated at 15 W.

Compact charger with swappable plates

The unit measures 5 by 3 by 3 inches and weighs little, making it easy to pack in a camera bag. Interchangeable plates let the same charger handle other Canon BP-series batteries beyond the three supplied. A Micro-USB cable is included for immediate use.

Questions about this item

How do I install the BP-511A battery and which step do people get wrong?

Insert each battery into the LTD2 charger with the contacts facing the pins, then plug the Micro-USB or Type-C cable into a 5 V 2–3 A source; the common mistake is using a 1 A phone charger, which lights the LCD but cannot deliver the 8.4 V 800 mA output needed for a full charge.

What maintenance or replacement will the BP-511A pack need later?

Lithium-ion cells lose capacity after roughly 300–500 full cycles; when run-time drops below half of the original 2600 mAh rating, replace the affected cell rather than the whole three-pack.

What limit shows up first under sustained use with the LTD2 charger?

The charger’s 8.4 V 800 mA output per slot is the bottleneck; charging two 19.24 Wh batteries together takes longer than a single cell, and the 15 W input ceiling prevents any faster rate.
