\n

The Canon EOS R6 Mark II is a powerhouse, but its high-speed burst rates and 4K video capabilities can drain the standard LP-E6NH battery faster than you might expect. While official Canon batteries are reliable, their premium price tag often pushes photographers toward third-party alternatives. I\u2019ve tested dozens of power solutions in the field, and I\u2019ve found that the right third-party option can offer comparable performance for a fraction of the cost. My top pick, the SmallRig USB-C rechargeable, is a total game-changer for modern workflows.<\/p>\n<\/div>\n\n

SmallRig LP-E6NH USB-C Rechargeable View on Amazon<\/a> View on B&H<\/a><\/h3>\n

Best For:<\/span> Travel and hybrid shooters<\/div>\n

Rating:<\/span> \u2605\u2605\u2605\u2605\u2605<\/span><\/div>\n <\/div>\n

The SmallRig LP-E6NH is arguably the most innovative battery I\u2019ve used in years. Featuring a 2400mAh capacity, it matches the R6 Mark II\u2019s power requirements perfectly, ensuring you get that vital “H+” high-speed mechanical shutter icon. What sets it apart is the built-in USB-C port. You can charge this battery directly from a power bank or car charger without needing a bulky external cradle. In my testing, the charging speed via USB-C is surprisingly snappy, taking about 2.5 hours from empty to full. The shell is made of high-quality fire-retardant ABS, giving it a premium feel that doesn’t swell like cheaper alternatives. The only minor drawback is that the USB-C circuitry takes up a tiny bit of internal space, but the efficiency of the cells compensates for it. If you hate carrying extra chargers, this is the definitive choice for your kit.<\/p>\n

Wasabi Power LP-E6NH (2-Pack) View on Amazon<\/a> View on B&H<\/a><\/h3>\n

Best For:<\/span> Event photographers<\/div>\n
Key Feature:<\/span> Grade A cells with 3-year warranty<\/div>\n
Rating:<\/span> \u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n <\/div>\n

Wasabi Power has been a staple in my camera bag for over a decade. This 2-pack of LP-E6NH batteries offers a massive 2250mAh per cell, which provides nearly identical shot counts to the OEM Canon version. When shooting a wedding with the R6 Mark II, I found these batteries reliably supported the 40fps electronic shutter without any voltage drops. The kit usually includes a dual USB charger, which is much more portable than Canon\u2019s wall-plug version. One thing I appreciate is their 3-year US-based warranty; it shows a level of confidence you rarely see in third-party brands. While they might show a “communication error” on very rare occasions if the firmware isn’t updated, a simple restart fixes it. For those who need multiple backups for a long day of shooting, the price-to-performance ratio here is unbeatable.<\/p>\n

BM Premium LP-E6NH View on Amazon<\/a> View on B&H<\/a><\/h3>\n

Best For:<\/span> Hobbyists on a tight budget<\/div>\n

If you have spent all your savings on the R6 Mark II body and a nice RF lens, the BM Premium batteries are a lifesaver. Marketed with a 2600mAh capacity, they actually perform closer to about 2100mAh in real-world use, but that’s still plenty for a casual afternoon of street photography. They are fully decoded, meaning you\u2019ll see the accurate battery percentage on your LCD screen, and they work perfectly with the original Canon LC-E6 charger. I\u2019ve noticed they lose their charge slightly faster when sitting in the bag compared to the SmallRig or Watson options, so I\u2019d recommend topping them off the night before a shoot. They might not always trigger the “Green” high-speed display mode on the R6 II during low temperatures, but as a “just in case” backup in your bag, they are worth every penny.<\/p>\n

Watson Pro LP-E6NH View on Amazon<\/a> View on B&H<\/a><\/h3>\n

Watson Pro is often the “professional’s third-party choice,” and for good reason. They prioritize safety and heat management, which is critical for the R6 Mark II when recording 4K\/60p video. In my experience, Watson batteries have the most consistent discharge curve; you won’t see the battery drop from 20% to 0% suddenly like cheaper clones. They feel physically robust, with tolerances that fit into the camera battery door just as smoothly as the Canon originals. While they are more expensive than Wasabi or BM Premium, you are paying for peace of mind. They consistently support the maximum frame rates on the R6 II and don’t trigger any “non-genuine” warnings. If you are doing paid client work and can’t afford a battery failure, but still want to save $30 over the Canon branded ones, Watson Pro is the way to go.<\/p>\n

Neewer LP-E6NH with LCD Charger View on Amazon<\/a> View on B&H<\/a><\/h3>\n
\n
Best For:<\/span> Organization-focused shooters<\/div>\n
Key Feature:<\/span> Smart LCD dual-charger<\/div>\n
Rating:<\/span> \u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n <\/div>\n

Neewer has stepped up their game recently, and this LP-E6NH kit is a perfect example. The batteries are solid 2250mAh performers, but the real star is the included dual-slot charger. It features a bright LCD screen that shows the exact percentage of charge for each battery, which is infinitely more useful than a blinking light. I find this incredibly helpful when I’m in a rush and need to know which battery has 90% versus 40%. The batteries themselves are fully compatible with the R6 II’s high-speed modes. I\u2019ve noticed the Neewer batteries run a tiny bit warmer than the SmallRig ones during intense video sessions, but they remain well within safe limits. It’s a fantastic all-in-one starter kit for anyone new to the Canon mirrorless ecosystem who needs to build up their power reserves quickly.<\/p>\n

Buying Guide: How to Choose a Third Party Battery<\/h2>\n
\n

When selecting a battery for your R6 Mark II, you aren’t just looking for “something that fits.” The R6 II is a high-performance machine that requires a specific voltage and amperage to unlock its full potential, particularly the 12fps mechanical burst rate. You will know a battery is performing correctly if the drive mode icon on your screen is green. If it’s white or blinking, the battery isn’t providing enough juice. I always prioritize “fully decoded” batteries, which ensure the camera can communicate with the chip to provide accurate timing and health data. Expect to pay between $20 and $45 for a quality third-party option; anything cheaper often compromises on safety circuits, which isn’t worth the risk to your $2,500 camera body.<\/p>\n
