HaHa I just got home with a new Husky extended hedger with a 9.4Ah battery. Not sure what the RRP for that battery is but I think it's only about $50 more than the 5.2Ah. I got a nice discount on the complete unit.
When I demoed it earlier this year, I thought it was a bit heavy on the cutter bar end so I was hoping the bigger battery( 0.5kg heavier) might balance it better, but just holding it now, it still feels heavy at the end.
The loop handled line trimmer was very tempting too. I really think I need it too, just to get another battery
