I am fixing to buy some Sanyo Eneloop batteries for my Foxpro and also other items around the house that require batteries. I have read quite a bit on here about batteries and was about to go with Tenergy, but everyone seems to prefer the eneloops. Anyway, do I want the white eneloops or the ones in the Black package that say XX or something like that? Also, what charger should I get without dropping a lot of coin? Thanks.
