Able to power my Teradek while powering the camera streamlines the need for multiple packs.

Love this battery. I've been using it for 3 years and it always lasts a long time and having the D-Tap to power accessories on my EVA1 is great. It's a great alternative to larger V-Mount setups when you are looking to keep things light.

I wish Core would make an L series battery just like this one with a D-Tap.

Well, let me tell you a tale.

I purchased this battery several years ago and liked its reliability and ability to allow for me to run my camera for very long recording sessions. Therefore, I felt the need to purchase a second one for my second camera. The first one that came from B&H was DOA (Dead on Arrival). I tried several times to get the new battery to begin a charge cycle with no positive results. I quickly called B&H for a RMA and spoke with Lee (sp?). He was very helpful in resolving my issue. I asked if there was a possibility of checking the replacement battery prior to shipping; he could not do this. So, with a bit of trepidation, I acquiesced to the swap. The replacement battery came in roughly a week later. Again, the battery was DOA. More than a little concerned, I began a series of placing the battery onto the charger (Panasonic Model Charger), removing the battery when the charger indicated an error, then placing the battery on the charger again. After about the eighth attempt, the battery began to take a charge. A few hours later, it was full!

Fast forward to about a week later, I had a chance to use it during a long recording session. Not only did I run the camera with the battery, but the battery supplied power to my Accsoon transmitter. I ran that battery for several hours without issue.

Final Word: If you need a high capacity battery, this one is great. However, the caveat is that you may have an issue with a unit that may have been on the shelf for a while.

It works.

This battery allows me to shoot for a long time. Definitely recommend it.

Core SWX Nano VBR98 will love you long time. Plus it can power your camera and an external monitor recorder via D Tap simultaneously. Repurpose your V mount batteries to power your lights. What more could you ask for?

This new Core SWX battery is working great on my Panasonic UX-180. It’s survived one major shoot so far, and powers my on-camera monitor from the 12v D-tap. Plenty of power at a fraction of the cost of a comparable OEM battery. We’ll see how long it lasts.
Also, unlike some reviewers, I had no problem charging it out-of-box on a standard Panasonic charger. The new battery was recognized right away and triggered fast-charge mode after a few minutes. Maybe some units have QC issues, and I just got lucky? So charge the battery on arrival (and keep the receipt)!

1st NANO-VBR98 I bought for my Panasonic AG-CX350 camcorder was back in 2021. I love it! Still works great. 2nd one I bought last month would not charge. Sent it back to B&H for a replacement. Got the replacement and IT would not charger either. Anxiety set in. Contacted B&H customer service for help. They communicated a few times with Core SWX Tech support about the problem and finally got a good answer from them that these batteries need what Core calls a "Jump Start" procedure when initiating the 1st charge. This trick is putting it on and off the charger, back and forth numerous times before the charger "sees" it and starts charging it. Once the charge light stays a solid orange and is not blinking, the "Jump Start" is successful and the bottom green battery level indicator light on the actual battery will blink and that's a good comforting sign that the battery will be successfully charged completely from that point on with the charge light turning the normal solid green when full charge is achieved.
