A part of the review has been auto-translated.
It's been tested. Unpretentious assembly. I'm positive about balance and weight. The speed regulation is from position 1 to 6 in 11 positions. Although the battery has a button to signal the state of charge, the diodes show a full state without load even when the battery is almost discharged. Alarms indicate battery charge rather than charging status. At full power it has decent parameters, but after quite a short time the thermal protection worked and the device itself switched off. Stable performance showed for a long time when adjusted to 7 position of the controller marked with 4 position. This device does not fully replace network or gasoline devices, but finds its use, due to its weight, fast usability and the ability to interrupt blows, which is what the network does not know. A little disappointing can be the short full power functionality.
Product Lithium battery does not work and does not accept charging
