There are several ways to hide batteries. The lightest and most common is using curtains. This is probably the best option, since the easier the fabric will be, the more it can pass warm. The second option is the hiding of the battery using the screen. They come in different types. One of the most inexpensive is a metal screen. But it is not very convenient, since firstly, it is suitable only for a certain type of batteries. During operation it can heat up and does not always pass warm air well. Especially if you want your batteries to be hidden by unique screens, then using metal screens you will not achieve this.
They are performed in mass, most often the same color and shape. Of course you can decorate them yourself, but this will need skills and free time. Wooden screens are more practical. Their choice is greater than metal. Such thermal panels are more expensive, since in manufacture it requires a more strict approach and better material. Not every type of tree is suitable for such a panel. The plastic screens are inexpensive, but they have lost their popularity, as there is a rumor about their harm to health. They say that when heated a plastic, some toxin that harms health is highlighted.
