Four BP-511A batteries with dual-slot USB charger

The pack contains four lithium-ion batteries rated at 7.4 V and 2600 mAh each, together delivering 19.24 Wh per cell. A single LTD2 charger with both Micro-USB and Type-C inputs powers two batteries simultaneously at 8.4 V and 800 mA per slot. An integrated LCD shows real-time charging status and remaining capacity for each bay. The kit targets photographers using compatible Canon EOS, PowerShot, Optura, ZR, DM and IXY models that accept BP-508, BP-511, BP-511A, BP-512, BP-512A, BP-514, BP-522 or BP-535 cells.

Sustained charging at 800 mA per bay

When both slots are occupied the charger maintains a steady 800 mA output to each battery without dropping to a lower trickle rate. The 5 V 2-3 A input requirement means a standard 15 W USB power adapter can sustain the dual charge continuously. Heat stays low enough that the compact 5 by 3 by 3 inch unit does not need active cooling during extended sessions. Users who need faster single-bay charging or higher simultaneous current will not find it here.

USB power delivery limited to 5 V input

The charger draws only from 5 V USB sources — Micro-USB or Type-C — so it cannot exploit higher-voltage USB Power Delivery profiles such as 9 V or 12 V. Maximum input power is capped at 15 W, which matches the 8.4 V 800 mA dual output but leaves no headroom for quicker charging. A Micro-USB cable is included; Type-C cables are not. Photographers relying on laptop ports rated below 2 A may see slower charge times or incomplete cycles.

Questions about this item

Does the charger get hot or draw much power when charging two BP-511A batteries all day?

The LTD2 charger runs from a 5 V 2–3 A USB source with a 15 W input limit and delivers 8.4 V at 800 mA per slot, so heat and power draw stay modest during extended dual-battery charging.

What power source and cable must I already have to run the LTD2 charger?

You need any USB power adapter or port that can supply 5 V at 2–3 A; a Micro-USB cable is included, and the charger also accepts a Type-C plug for the same input.

Will the BP-511A batteries and LTD2 charger work with my older Canon EOS 10D and PowerShot G2?

Yes — the BP-511A cells replace the original BP-511/BP-511A packs used in the EOS 10D, and the charger is listed as compatible with the CB-5L and CG-580 chargers that shipped with the PowerShot G2.
