DMK Power NP-F970 F960 Rechargeable Li-ion Battery fit for Sony Cameras LED Video Lights & Monitors Style & Size Available (Non-Camera (For Lights/Monitors Only),9800mAh 2 Pack)

it does the job, I used it to power LED video Light, The build quality is not the best, but it's ok. I received a damaged unit, but the supplier was very helpful and replaced it. also has 1-year warranty so nothing to worry about for a while I would buy from this supplier again.

Ok

Takes forever to charge and discharges in less than 2 hours

good quality and durability

Good battery, works well with Ninja 5 recorder. 4k@25 can record for 2 hours on full battery. Keep in mind, the capacity of battery is 5500 mAh instead of 9800 mAh. I've charge from 3 to 100% and it shows only 5500 mAh. Charging time is more than 4-6 hours!

One of the batteries were damaged, the battery enclosure was opening up so had to tape it down with electric tape

Good

I bought four batteries. When i plugged them on my Godox LED light, they last 30 min and the battery voltage remains at 100% but switch off without showing battery drainage. i have similar older batteries that can run continuously for over 3 hrs. and use them again next day without charging. I trust these batteries here with me are faulty. Kindly advise as i want to return them
