Are All Lithium Batteries Deep Cycle

2/3 of a stop is a good value for my needs. the full stop was too much and 1/3 not enough at all.

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.

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.
