Finding reliable power sources for my equipment has always been a bit hit or miss, but these K&F Concept NP-F970 compatible batteries have been a solid choice. I needed dependable batteries for my video light panels and my field monitor while working from home and for outdoor shoots. Both batteries offer an excellent capacity, running my gear for hours without interruptions. One time, I used a battery to power my 20-watt video light for over three hours, which was quite surprising.

The inclusion of a dual USB charger is a nice touch, even though it charges a bit slowly. Overnight charging sorts that out for me since I can just plug them in before bed. I do wish the batteries had an onboard power indicator for ease of use, but that’s a minor issue considering their performance. Also, the charger’s imbalance when both batteries are inserted is noticeable but not a major problem for me.

In terms of design, they fit my devices without any hassle and performed on par with more expensive, branded options. I was initially sceptical given K&F’s primary reputation for other types of accessories, but these batteries have proved to be reliable, cost-effective additions to my kit. Whether I’m in my home studio or enjoying a scenic hike while capturing footage, these batteries ensure my gear stays powered.
