Two-pack BP-820 replacement for Canon camcorders

This pack supplies two lithium-ion BP-820 batteries rated at 7.4 volts and 2050 milliampere-hours each. They replace the Canon BP-820 and BP-828 cells used across the XA, XF, VIXIA HF G and GX series listed in the compatibility data. Video professionals and event shooters who need spare power for long recording sessions are the intended users.

Sustained discharge and built-in protection

Each cell delivers 15.2 watt-hours and includes over-charge, over-discharge, over-voltage, over-current and over-heating circuits that meet UL1642 and CE safety standards. The protection logic maintains stable output during continuous 4K recording rather than only during short bursts, and the chemistry is rated for a long cycle life so capacity loss stays gradual over repeated full discharges.

Check your charger and camera model before ordering

Verify that your charger is the Canon CG-800 or another unit explicitly rated for BP-820 and BP-828 packs. Confirm the camcorder appears in the supported list — XA10, XA11, XA15, XA20, XA25, XA30, XA35, XA40, XA45, XA50, XA55, VIXIA HF G21, G30, G40, G50, G60, GX10, XF400 or XF405 — because other Canon models use different battery interfaces.

Questions about this item

Does the Kastar BP-820 2-pack generate noticeable heat or noise during all-day shoots?

The lithium-ion cells include over-heating protection and have no moving parts, so they run silently and stay cool under normal use.

What charger do I already need to power these BP-820 batteries?

They are compatible with the Canon CG-800 charger, so you must own or buy that model to recharge the pack.

Will the 7.4 V 2050 mAh cells work in my older Canon XA10 or VIXIA HF G30?

Yes, the pack replaces Canon BP-820 and BP-828 batteries and fits every listed camera from XA10 through XF405.
