I currently have an X60vn that takes 6x18650s. Is there another charger out there that has the capability of charging them all at once and without splitting the charge rate between them? Right now I've been using the D4 and my Pila charger (4 in the D4 at 350mAH and 2 in the Pila at 600mAH) but since the D4 is so cheap I was thinking of just buying a second one and putting two in each charger, thus running three chargers at once. Does this make sense or is there another charger that will do all this?
