Images are deceptive
The media could not be loaded. I don't know what I was thinking seeing those product photos but, trust me now as you can see, these batteries are not very clean lookingLooks aside, the dimensions are precisely 2cmX3cmX0.6cmThe leads come pre insulated which is good to prevent short circuit during shipping.The battery also has circuit board but I don't trust it, you can use 5v USB from computer, don't use mobile charger as it can output a lot of current which can cause damageTo charge it care must be taken to never charge this beyond 4.2 volts of unplugged battery voltage. So use a suitable LIPO battery management circuit OR else fire 🔥 hazard ❌.I'll updated this review later when the cell naturally gets damaged due to normal usage.
