When received you need to charge these batteries and i use an xtar rocket which allows up to 2amp charging but i charge these at 1 amp as i am in no rush

The only little issue is they are not supplied in a battery case and they come individually boxed so for safety it’s best to seek out a case that holds this size battery

This battery comes as a set meaning you have 2 batteries and are perfect for fitting into vaping mods like the geekvape aegis

Ive had no issues so far and they seem perfect for my needs
