The performance of your Inspire 1’s Intelligent Flight Battery is subject to environmental factors. Maintaining a suitable temperature (above 20˚C) ensures proper battery performance. Thus the insulation sticker is designed to keep the battery within the temperature range. Ideal scenario is to apply the insulation sticker to the Intelligent Flight Battery when environmental temperatures are lower than 5˚C and remove the sticker when environmental temperatures exceed 5 ˚C.
