Here's my "pro tip" for purchasing less-expensive 20V DeWalt batteries, although it only works at the end of autumn: around the first annual winter freeze, all the outdoor tools go on sale. Typically outdoor tools are paired with their largest AH battery available; sometimes the pair retail for less than just a single 4AH+ battery [sometimes "half off"]. Doesn't always work out, but I do this every other year (and have multiple weed whackers lol). My last 4AH 20V Dewalt battery cost me $49 this way.
