4/5 Battery & RuntimeValue

“I bought it at $134, no regrets (besides it dropping in price right afterwards; no, I don't care about going back in to ask for a price adjustment).”

“You got a good price with the battery and charger, but it's not what I would want if I did construction professionally.”
