I have some lights which I want to be able to use with batteries so I can use them outdoors or on location where there is no power.These NPF970 batteries are excellent value, they aren't the cheapest but they're also not the most expensive and I've read lots of positive articles about PowerExtra batteries and my experience mirrors that.I ran an Amaran 60D (LED COB) and an Amaran P60X (LED Panel) both at 80% brightness at 5600K and each light was powered constantly for over an hour before the battery discharged. (the 60D ran for 1hr 15 minutes, the P60X ran for 1 hr 24 minutes). These are quite power hungry lights so this is pretty impressive, I've known others use smaller batteries and not even get 30 minutes of power!The batteries take a while to charge (all 4 batteries in the charger takes about 8 -10 hours), the charger got very warm but more so than any other I've used and as soon as the batteries were charged it went cold. The charger has an LCD screen which shows the charging status of the batteries and it feels well built.These are large batteries but there's no way of getting around that, NPF970 batteries are indeed big batteries! These feel well constructed, they don't seem to get hot and they fit well on the charger and into the battery plates of my lights. I have no complaints at all and will definitely getting more PowerExtra batteries in future.The batteries come in 2 boxes of 2, I would recommend keeping the boxes as the batteries fit into them snuggly and it make it easy to carry them around in your kit bag.

Great set of batteries. And fast charger, all batteries 🔋 charge at the same time quite quickly too.Will grab another set of 4 for my lights.Great value for money

Excellent product for the money. Charges quickly and works according to stated parameters. I advise you to buy.

Great. Nice and heavy which makes them feel good quality. Batteries seemed to be as good as any others I have bought

A well made charger unit with a normal fiq 8 mains input with a good LED bar graph so you can see the state of charge on each battery - great price too for 4 x high capacity batteries

3 batteries and charger we can one time charge save time and money performance is too and life

These were ok at first but after a year they don’t last long at all

I think this is a great purchase.
