Questions about this item

What is included in the pack and do I need any extra cables?

The pack contains one AC wall charger with a foldable flat plug and four BP-915G lithium-ion batteries; the charger plugs directly into a wall socket so no separate cable is required.

Should I choose the 25.9 Wh version or a different capacity?

Each battery is rated at 25.9 Wh (3500 mAh at 7.4 V); this is the only capacity offered in the pack, so there is no alternative to select.

What does the 600 mA charger output mean for actual charge time?

The charger delivers 4.2 V at 600 mA, so a fully depleted 3500 mAh battery will take roughly six hours to reach the green-light full-charge indication.
