Compare the Canon BG-R20 and BG-E18 battery grips to find which fits your camera and shooting style. Key differences in compatibility, battery type, and ergonomics explained.
Quick answer
Choose the Canon BG-R20 if you shoot with an EOS R5, R5 II, R6, or R6 II and need extended runtime with LP-E6NH batteries. Pick the Canon BG-E18 if you use a 750D or 760D and want a cost-effective way to double your shooting time with LP-E17 cells.
Compatibility is the first hard stop
The BG-R20 is built exclusively for Canon’s full-frame mirrorless R-series bodies (R5, R5 II, R6, R6 II). The BG-E18 is designed for the older DSLR EOS 750D and 760D. There is no cross-compatibility between these two grip families, so your camera model dictates your choice.
Battery type and runtime trade-offs
The BG-R20 accepts two LP-E6NH batteries, which are high-capacity cells used by Canon’s pro mirrorless line. The BG-E18 holds two smaller LP-E17 batteries. While both grips effectively double your battery life, the LP-E6NH pack offers higher total watt-hours, meaning longer continuous shooting for power-hungry R-series cameras. However, LP-E17 batteries are lighter and less expensive to replace.
Ergonomics and handling differences
Both grips improve vertical shooting comfort and add a secure handhold. The BG-R20 includes a more robust, sculpted grip surface that matches the larger R-series body. The BG-E18 is more compact, keeping the 750D/760D setup relatively light. If you shoot with heavy telephoto lenses, the BG-R20’s deeper grip may feel more balanced; for casual walkaround use, the BG-E18 adds less bulk.
Decision rules
- Check your camera mount: If you own an EOS R5, R5 II, R6, or R6 II, the BG-R20 is your only compatible grip. For a 750D or 760D, the BG-E18 is the correct match. Compatibility is non-negotiable; confirm your camera model before buying.
- Consider your battery ecosystem: If you already have LP-E6NH batteries, the BG-R20 leverages your existing spares. If you use LP-E17 cells, the BG-E18 keeps your system consistent.
- Evaluate shooting demands: For all-day event or video work on an R-series body, the BG-R20’s higher total capacity matters. For casual DSLR use on a 750D, the BG-E18 provides ample extra runtime at a lower cost. Match the grip’s power capacity to your typical shooting duration.
