The Kastar BP-820 is a lithium-ion replacement battery rated at 7.4V and 2050mAh with 15.2 Wh capacity. It fits a wide range of Canon XA, XF and VIXIA camcorders including the XA10, XA11, XA15, XA20, XA25, XA30, XA35, XA40, XA45, XA50, XA55, XF400 and XF405 models. The pack contains one battery.

Thermal Safety and Run Time

Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating during normal operation. Cells meet UL1642 and CE safety standards for reliable use. The high capacity design extends recording sessions compared with lower-rated packs.

Charger Compatibility

The battery works with the Canon CG-800 charger already used for original BP-820 and BP-828 packs. No additional cables or software are included in the single-battery package. Buyers who need a charger or multi-bay charging station must source those separately.

Questions about this item

How do I install the BP-820 battery in my Canon XA30, and what step do people often miss?

Slide the battery into the compartment until the latch clicks; the step users miss is confirming the charge-indicator lights activate, proving the contacts are fully seated.

What maintenance or replacement will the BP-820 need later?

The 7.4V 2050mAh Li-Ion pack loses capacity over cycles; plan to replace it when run time drops below your shoot requirements, as the protection circuit cannot restore lost capacity.

What limit appears first during sustained use of the BP-820?

The 15.2 Wh capacity sets the hard runtime ceiling; the built-in over-heating protection will cut power before the cells exceed safe temperature during continuous high-draw recording.
