Hi,my name is Leonardo and I bought four batteries Shockli 26650 5500mAh top button for my diving flashlights, two flashlight 3600 Lumen each, in place of previous ones that weren't powerfull enought (not really high current cell). These batteries are very powerfull! the performance are on the top (like ijoy / Golisi) but with more capacity. I'm very happy for purchase and thank you to Simon (marketing Director) for the kindness and willingness shown.I recommend all these batteries.
Bye
