i bought one battery and though hey i need a charger, but then i realized i can save the $40 that the charger cost and get one more battery, and use my bench top psu to charge the batteries.
I like harbor freight, i like this battery and the impact wrench i got the batteries for, i thought i would just be cheap and do it my way.
side note, they had some crazy sale at the time i bought this stuff. i think i paid $57 for the drill, got one battery free, and the second one for $27.
i also bought a set of metric deep well non impact sockets for like $14 that i plan to use on my vehicle repairs. i grown tired of the air hose being in the way.
