Built a 1S3P pack with these for camping, lasts 3 nights. EVE 33V is reliable, voltage stays above 3V under load.
At 5A draw, voltage holds nice and flat. 10A max is safe for most home electronics. Good for remote controls too.
I use these in a USB power bank kit, they provide over 6000mAh at 5V. 10A allows fast charging. Flat top works.
Cells arrived at 3.5V, well packaged. Used in a portable fan, runs 8 hours. I'm satisfied.
Replaced all my AA NiMH with these EVE 33V and a small boost converter. 3300mAh runs lights all night. 10A is more than enough.
