Lithium Marine Deep Cycle Batteries

I purchased several of these to run scientific equipment in a backcountry setting. We used to have to lug heavy deep-cycle lead acid batteries around which weighed three times as much and hold half the power. They also took a full 24 hours to charge, but the EcoFlow Delta charges in an hour or two. Such an improvement to our setup, can't imagine going back!

Very versatile, You can use lithium batteries to power it

Nothing beats these lithium batteries...they don’t die.

Purchased Watson batteries instead of Panasonic as a trial. They have had one cycle of use, and have functioned similar to the Panasonic.

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

I've been using PAG batteries almost since they came out. They are the best batteries I've used in my 40 years and more as a Marine Wildlife cinematographer, and I've use many over the years. They give me a minimum of one hour plus top side use and as much or more in my Nuaticam underwater housing. The stacking ability is a real plus. They are also a lot less hassle in traveling as they are airline approved. The compact package they come in is a real plus, because they are lighter, smaller and easy to travel with.

Like the ability to change 2 batteries at the same time and keep them together. Thinking about getting another for my other two Lithium Ion batteries.

I love the compact size of the charger, and it seemed to charge my lithium batteries quicker than my last charger.

These lithium batteries are very light and last a long time. Charger works well too.

Much superior to alkaline batteries for use in my portable flash. Last longer, cycle faster.
