Four-battery kit for Canon XA and VIXIA users

This pack includes four lithium-ion BP-828 batteries and a single quadruple charger. Each cell delivers 7.4 V and 3300 mAh for a total of 24.42 Wh. The set suits videographers who need extended run-time across compatible Canon XA and VIXIA camcorders.

Quad charger replaces single-bay units

The supplied charger powers up to four batteries simultaneously through Micro-USB or Type-C input. It swaps charging plates to fit other Canon packs and shows real-time capacity on its built-in display. The upgrade makes sense when a shoot demands more batteries than a single-bay charger can cycle overnight.

Sustained charging splits current across bays

With one or two batteries inserted the charger outputs 8.4 V at 800 mA per bay. Adding a third or fourth battery drops each bay to 500 mA to keep thermals in check. This behaviour means full top-ups take longer when all four slots are occupied, but the charger remains stable during continuous use.

Questions about this item

What are the dimensions of each BP-828 battery so I can confirm they fit my Canon XA10?

Each battery measures 3.5 by 2 by 2.5 inches, matching the Canon BP-828 form factor used in the XA10 and listed camcorders.

How do I power the quad charger and what common mistake should I avoid?

Connect the charger via Micro-USB or USB Type-C using a 5 V 2–3 A 15 W adapter; the frequent error is using a 1 A phone charger which limits output to 500 mA per bay.

When should I replace the four 3300 mAh 7.4 V Li-Ion packs?

Replace them when run-time drops noticeably below the rated 24.42 Wh or the charger’s capacity indicator shows degraded health after repeated cycles.
