Two-Battery Kit for Older Canon Bodies

This pack supplies two lithium-ion BP-511/BP-511A replacements rated at 7.4V and 2600mAh each, plus a dual-slot USB charger. It targets owners of EOS 5D, 10D, 20D, 30D, 40D, 50D, 300D, D30 and D60 bodies who need spare power for long shoots.

USB Charging Limited to 5 V Input

The LTD2 charger draws 5 V at 2-3 A (15 W) via Micro-USB or Type-C and outputs 8.4 V at 800 mA per slot. It cannot operate from a higher-voltage PD source and provides no AC cable, so users must supply a suitable USB power adapter.

19.24 Wh Per Cell Covers Typical Day Trips

Each 19.24 Wh battery comfortably handles several hundred frames on the listed DSLRs. Extended video sessions or cold-weather work will exhaust the pair before evening, and the 800 mA charge rate means a full replenish takes multiple hours.

Questions about this item

Should I choose the BP-511 or BP-511A version for my EOS 20D?

Both BP-511 and BP-511A are listed as compatible; each battery in this pack is rated at 7.4V, 2600mAh, and 19.24 Wh, so either model fits the same cameras.

What does the 2600mAh rating mean when the battery is inside my EOS 30D?

At 7.4V the cell stores 19.24 Wh, giving roughly the same shooting time as an original Canon BP-511A in the EOS 30D.

How does the USB charger’s 8.4V 800mA output affect charge speed?

The charger delivers 8.4V at 800mA per slot, so two batteries charge simultaneously at that rate from a 5V 2-3A USB source.
