Default DBK brand of 18650 l-ion cell rating on cell 3350

It looks like I put this in the wrong forum if it is please move it to right one thanks

Most of the time the non brands of cells fall very short of what it says on the cells milliamperes

Not in this case useable milliamperes 2500 and that is where the amperage is still at about 1 amp load

The battery tester that I am using cuts off at 300 milliamperes
Cut off showing 2964

To me that pretty good

I got these battery packs at Walmart Black Friday sale on Thursday night $15.00

These batteries were in the device in the photo below

I was going to use these cells for my LED yard light project but I am having second thought on this

I have some other cells that I going to test that I might use instead with lower milliamperes rating some Chinese cells that I have because these cells are being used outside I really do not have real use for them I think if they show 1500 milliamperes I would be surprised

I have some pouch stile batteries that are rated at 4000 milliamperes which they do every bit of it four of these cells in parallel will take the place of six 18650 cells
