You should never charge your e-bike battery unattended! But with the right safety precautions, you can charge it indoors. Place the battery on a fireproof surface and away from flammable objects for charging. The VLITEX e-bike battery bag or the VLITEX fire protection blanket, for example, offer good heat resistance. They are also available in small formats that are suitable for rechargeable batteries or e-bikes. Silicone-coated glass fiber fabric can withstand temperatures of up to 1,000 °C for short periods. If you charge the battery in the VLITEX e-bike battery bag, make sure that the temperature does not get too high. The first thing you will notice if your battery is faulty is that it becomes unusually hot.
