Just to confirm if I did get that one I wouldn't need a charger right? And what specific battery would I need for it? mAh / V etc.
You can charge if from there but personally I would still get a charger, it's just a better option and I'd say, a little safer..and the i2 is pretty cheap. Also when money is a little better you can charge two at once and have a spare for when your out all day.. I've heard a few dodge stories about the kbox onboard charging port to be honest..
Great battery is the Sony VTC5 18650 2600MAH 30A, they are really good and that's what Id get, you can get the Samsung 25r which are cheaper but again, I'd spend the extra from the get go..
