Are Chinese Lithium Batteries Any Good

Very versatile, You can use lithium batteries to power it

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

Wonder if Fittest (Chinese Copy) is as good or even the same?

It's good to have a battery testing on hand and this one does the lithium and alkaline batteries. One thing I would note is for rechargeable batteries that have been handled a lot; it a good practice to clean terminals with  isopropyl alcohol otherwise it could give inconsistent results. This is covered in the manual and in their FAQ on the website. It is not readily apparent as to why you would need to read the manual for such a straight forward device :).

Easy to use, good value, decent image. Use lithium ion AS batteries and it will change your experience. Lasted an entire season (thousands of pictures) with some left in the tank.

Put my 1st camera out a year ago, with 8 lithium batteries and they lasted 7 months wich I thought was pretty good.Was very reliable and took good pictures.I just set it out again and am getting pictures already. I got another one for Xmas and have activated it but not set it out yet.I am looking forward to the pictures I will get from this one.

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.

had cheap chinese batteries as backups for the camera but they failed, so now that the price has come done I'm using the sony 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.
