Ok, so if it's the same threads, the same cartos, that means it has the same power connection system as well.. The only difference in the chargers would be charging amperage and voltage I think i can safely deduce.. That being said, I will have a kGo charger that is made to work with the kGo batteries I have.. Can one use the same charger for a small 510 slim battery and it just be more than enough?? or will it overwhelm the little battery and make it go boom?
