Dont come much faster than this

dont know about the budget tho :-\

Thats just what I was thinking... hmmm nice.
I use a "Pro Peak" charger I got for my airsoft batts a few years back. Sounds similar in operation to the one WW recommended. Trickel or hit the button and it'll fast charge a 3300mah batt in about 1hr, then reverts back to trickel. It'll even tell you if you've miss connected the batter and comes with the 12v car battery charging connectors. Cost btwn £30-£40 but best not to buy from an airsoft retailer as they usually up the price something cronic.
Word of warning though, dont fast charge late at night as the alarm that signals its finished is louder then my car alarm... My elderly neighbours think there's an air raid coming :-[
