I feel like your mower is well covered by now but for weed eater and blower I use the Makita 36v line and love it. I do my house and my parents house (~.7 acres total) for both trimming and blowing on just two 5.0ah batteries. The kit I bought came with 4 for a little less than a gas trimmer would cost and I already had a bunch of Makita tools so it was a no brainer for me.

I believe they came out with the quick change head system for the trimmer similar to some gas powered alternatives so you can do trimming, edging, bush/tree trimming, etc all with one tool now as well.
