looking for a 4bay charger for my e-cig lithium batteries. i also use nimh batteries around the house in various devices. so, is the latest version of this D4 the best charger currently on the market? i don't care if it has more than 4 bays but i don't want to go below 4. is there anything that can do it all or would i be better getting one for my mod batteries and a seperate one for my household nimh batteries? i don't mind spending more fore a quality productbut there doesn't seem to be a high-end charger or am i missing something? any help/advice will be gratefully accepted- now what should i buy?
