I'm new to mods and I've just been reading about rechargeable batteries and how to charge properly. I'm seeing that you shouldn't be charging above 4.2v however I notice that when I put a freshly charged 18650 battery (using Intellicharger i4) into my Vamo V5 it shows 4.3v. I want to get the most out of my batteries so I'm doing my homework. Is this a charger defect or is if my batteries? Or both? I'm pretty sure my first bought 18650 batteries are knockoffs but I'm getting good authentic ones soon. Any help is appreciated.
