This parquet is not a replacement for a powerful network parquet, but an addition to it. For a quiet summer-autumn work on the frame, etc. fits great. We need two five-royed Akum. It is already difficult to dissolve a 40x100 board - a 5Ah akum is enough for 2-3 meters of cut, then the akum overheats and kirdyk, it is necessary to change the akum. I began to set the depth to 25 mm and cut from both sides - it's a little more fun, but not much. At a temperature of minus five, the autonomy of the batteries is reduced by half. I keep them in my bosom. I'm thinking about some kind of warm casing for them . Or, through LATR and an empty Akum, make 18 Volt power from the mains for the winter .
