BM Premium BG-C18 Battery Grip Replacement for Canon EOS RP - Longer

In this review the BM Premium BG-C18 Battery Grip Replacement for Canon EOS RP is assessed for photographers who need extended runtime and improved handling. The bottom line: this pack effectively doubles shooting time by accepting one or two LP-E17 batteries and adds a vertical shutter release for more stable portrait shooting. The review focuses on practical performance, comfort, and battery details so a buyer can decide whether the grip and included BM Premium LP-E17 battery are the right upgrade for their EOS RP kit.

Key Features

• Dual battery power: Accepts one or two LP-E17 batteries to roughly double usable shooting time for long sessions away from chargers.
• Vertical shutter release: A dedicated vertical shutter button and scroll wheel let users shoot portrait orientation with the same ergonomic controls as landscape mode.
• Included battery: Ships with one BM Premium LP-E17 battery so the grip is ready to use out of the box for immediate extended runtime.
• Comfortable grip design: The textured handle provides a more secure hold and improves stability for both handheld and vertical compositions.
• Battery specs: Uses a 1040mAh, 7.2V Li-ion cell (7.5Wh) which balances capacity and weight for extended recording and stills work.
• Warranty coverage: The battery includes a one-year warranty, offering reassurance for regular use.

Who It's For

The BG-C18 is ideal for enthusiasts and hybrid shooters using the Canon EOS RP who want longer continuous shooting for events, travel, or extended video recording without swapping batteries frequently. Portrait and wedding photographers will appreciate the vertical shutter release and improved balance when using longer lenses.

Casual users who only shoot short sessions or those who prefer the smallest, lightest kit might find the grip unnecessary. Also, photographers who require manufacturer-specific features beyond basic grip controls should confirm compatibility with their accessories before purchasing.
