I am extremely unimpressed with the latest battery stihl products. They are made cheap, with low quality parts. And frankly, I don't care for excuses, stihl is supposed to mean quality, and that means quality control as well! Specifically, the msa 160 c-bq chainsaw, and the bga 57 leaf blower. The chainsaw, while it worked great when it worked, constantly leaked bar oil when stored inside, in a temperature controlled environment, using stihl brand name bar oil. And after less than 3-4 hours of total usage, spread across ~2 years, the motor magnets have let go and now the saw requires a replacement motor, which costs about 350 dollars(I was just given this number by a stihl service dealer). I have never abused the saw, I cleaned it after every use, and it was always stored inside in the perfect conditions. Clearly, just a cheap tool. The leaf blower is really fairly decent, when it works, which seems to be very temperature dependent. I have had multiple occasions, where it simple stops working, especially as the temperature outside approaches 25 degrees celsius or more. I have been using it for light duty blowing off leaves from a walking path, and it will just stop working, and not turn back on. Battery fully charged, and different batteries, will not change this. A few hours later, and magically, the blower works again. And sometimes, shuts off again, sometimes works for awhile, but never reliably. And once again, this tool has been respected more than the average homeowner/tradesperson would. Their electric quick cut works pretty good, but the battery does not last anywhere near advertised, whether you use the ap300 or the ap300s. And that is with light pressure. I would really like to know their testing environment, because i don't think the tools are tested in proper conditions to show actual, true results. I have been using stihl products for over 20 years, and while their gasoline powered line really seems solid (i have rebuilt many ts400 and ts 410 saws), their electric line is not recommended. Unless you want to have constant headaches, and lose time/profit on a job, i would strongly recommend buying a different brand name. I won't be buying another stihl. Literally, never. What happened to you stihl?
