My friend look on ebay. Just search ryobi one battery there is loads of aftermarket batterys and you can get upto a 9ah battery to fit the ryobi one ... there is 5 6 7 8 9 ah available it's generally best to buy a pair to get the best deal 😉
Does anyone know how the brushless equivalent performs compared to the brushed model shown in the video? I am specifically referring to the brushless model with a similar small nozzle, selling for about 200AUD in Bunnings.
