Yes, that I think is one of their more economical batteries. I, myself bypassed them completely. Here's the battery that I finally selected for my workshop. Performance has been excellent, and they have double the 50% discharge life as the one you referenced. Keep in mind though that they are F***ing heavy.By chance I found a small provider that has 5 of this in stock https://rollsbattery.com/battery/6-fs-gc/ but I am a little disappointed at the life cycle at 50% discharge of about 1500, he is asking 250€ each.
