This product is described as 16 V. This is of course wrong, there is only the 18V. Unfortunately, the 4AH batteries are much cheaper than this offer. Also here on Galaxus... the 6 AH battery is available for less than 100, so why should you take this one? For just under 70.- there is exactly this one, so 50.- cheaper. For 75 even the Powerplus 4Ah,m with better cells and much smaller. Just because it says Husqvarna on it 122? It is and remains a Bosch PBA. No matter what it says on it.
