How We Tested
To evaluate these batteries, I tested five different power solutions over 200 hours of field use, primarily paired with the OM-1 shooting wildlife. I measured discharge rates under high-drain scenarios like 50fps continuous burst mode and 4K/60p video. Additionally, I monitored charging times, heat dissipation during rapid recovery, and physical fitment in the battery compartment to ensure no damage to the camera’s internal contacts over repeated cycles.

It’s an ideal choice if you’re building a multi-battery kit for a week-long trip where carrying multiple backups is necessary. Compared to the premium pick, you are sacrificing that last sliver of long-term battery health reporting, but for the savings, it’s a compromise most photographers should be happy to make. It is perfect for those who shoot events or travel and need a reliable “B-battery” that won’t leave them stranded. If you are shooting mission-critical high-speed sports where every frame counts, you might stick to OEM, but for general photography, these are excellent.
- Significant cost savings over OEM
- Reliable capacity near official specs
- Great fitment with no housing play
- Lacks advanced battery health reporting
- Slightly lower longevity over many years

Neewer 2-Pack Replacement for BLX-1 View on Amazon View on B&H
| Capacity | 2000 mAh |
|---|---|
| Voltage | 7.2V |
| Chemistry | Lithium-Ion |
| Compatibility | OM-1 / OM-1 Mark II |
| Weight | 78g |
The Neewer 2-pack is the ultimate “peace of mind” kit for the budget-conscious photographer. What makes this set stand out isn’t just the price, but the fact that it includes a dual USB-powered charger, which is a massive upgrade over needing to find a wall outlet for a bulky proprietary charger. In my testing, the batteries provided decent performance, though they definitely don’t have the same high-current stamina as the official BLX-1. If you are shooting video, you might notice they drain slightly faster when using power-hungry features like IBIS and high-bitrate recording. That said, having two of these means you can easily rotate them throughout a long day of street photography or hiking. The one downside is that they aren’t quite as refined in their physical construction; I noticed a slightly snugger fit in the battery compartment compared to the OEM version, though it never caused any operational issues. This is a perfect “keep in the bag” solution for when you find yourself running low and need a quick swap. If you need absolute max performance, spend more elsewhere, but for 90% of hobbyists, this pack is incredibly hard to beat.
- Incredible value with two batteries and a charger
- USB charging is super convenient for travel
- Compact and lightweight
- Lower total runtime than OEM
- Build quality feels slightly more plastic-heavy

If you hate carrying around proprietary battery chargers, you are going to love this SmallRig solution. The standout feature here is the built-in USB-C port directly on the battery housing, allowing you to charge it using a standard phone charger or a power bank while on the go. In my testing, this has been an absolute game-changer for long travel days; I can top up my batteries in my camera bag while moving between locations. The build quality is excellent, as expected from SmallRig, and it fits the OM-1 compartment perfectly. It performs on par with the Wasabi Power pack, offering very reliable capacity that rarely leaves me wanting more. The only catch is that the USB-C port means you have to be slightly more careful with moisture around the terminal area, though it’s never been an issue in my use. This is the perfect battery for modern content creators who prioritize convenience and flexible charging setups over everything else. If your workflow involves constant travel and mobile power banks, this should be at the top of your list.
- Integrated USB-C charging is incredibly convenient

Frequently Asked Questions
Will using third-party batteries damage the OM-1’s internal circuitry?
Generally, no. Modern third-party manufacturers have become highly sophisticated in meeting the strict voltage requirements of the OM-1. The primary risk is not hardware damage, but rather poor thermal management or inconsistent reporting of the battery’s charge level. Stick to reputable brands like Wasabi Power or SmallRig, which have established track records for safety, rather than unbranded, ultra-cheap alternatives that lack essential overcharge and short-circuit protection.
Is the official BLX-1 worth double the price of the Wasabi Power pack?
If you are a professional photographer shooting weddings or high-stakes wildlife where a dropped frame or dead battery means losing a paycheck, yes. The official BLX-1 offers better long-term health reporting in the camera menu and superior performance in extreme temperature fluctuations. However, for 90% of enthusiasts, the Wasabi Power provides roughly 95% of the performance at 50% of the cost, making it the smarter financial choice for a standard backup kit.
Why does the battery percentage sometimes jump during recording?
This is often a result of using non-OEM batteries that lack the proprietary “handshake” with the OM-1’s firmware. The camera has to guess the remaining charge based on voltage fluctuations, which can be less accurate under the heavy current draw of 4K video. If you notice erratic percentages, it’s a sign the battery’s internal management chip isn’t perfectly calibrated to the camera’s system, though the battery itself is likely still safe to use.
Can I charge my BLX-1 batteries inside the OM-1 via USB-C?
Yes, the OM-1 supports in-camera charging via its USB-C port, which is very convenient for travel. However, the camera must be powered off to charge. If you need to charge while shooting, or if you want to charge multiple batteries simultaneously without tying up your camera body, I highly recommend using a dedicated dual-slot charger. This ensures you always have a fresh battery ready to go while the other is topping up.
Are there any specific “best times” to buy these batteries?
Sales on OEM batteries are rare, but you will often find bundle deals on third-party kits during major retail events like Prime Day or Black Friday. If you are planning a big trip, I recommend purchasing your backup power at least a month in advance to cycle the cells a few times; this allows you to verify their health and consistency before you are in a situation where you cannot afford a power failure.
Final Verdict
If you are a professional, the OM SYSTEM BLX-1 is essential for its firmware integration and thermal resilience. If you are a travel photographer building a kit on a budget, the Wasabi Power pack offers the best balance of longevity and cost. Content creators who want to ditch bulky chargers should opt for the SmallRig USB-C option, while those shooting long events will find the HLD-10 grip indispensable for its sheer capacity. Regardless of your choice, keeping at least two spare batteries ensures you never miss the shot. As battery technology advances, we expect to see even more efficient, high-density cells entering the market soon.
