celexon Battery Screen V2.0 Professional Plus 280 × 210 cm (138") Battery-Powered Motorised Screen

celexon Battery Screen V2.0 Professional Plus – motorised convenience without any fixed wiring

The celexon battery screen V2.0 Professional Plus is a motorised screen with a 280 × 210 cm viewable area (138", 4:3) that is powered by a built-in rechargeable battery: you don't need a power socket at the installation site or have to lay any cables. It combines the convenience of a motorised screen with the easy installation of a pull-down screen: charge the battery once, unplug it and use the screen wirelessly.

At the touch of a button on the radio remote control, the matte white fabric lowers from the closed housing and stops at exactly the same position every time. Unlike manually pulling down a pull-down screen, where you have to watch the height yourself, the image sits in the same place every time you use it – with no readjustment needed. The bottom bar closes flush with the housing and protects the fabric from dust and environmental influences when not in use.

Key benefits at a glance

• No fixed power connection needed: the integrated Li-ion battery (3,000 mAh) lasts for up to 500 extend and retract cycles per charge – charge it, unplug, project.
• Always the same image height: the motorised extension stops at exactly the same position every time, so the image sits right without readjustment.
• Radio remote control without line of sight to the screen, plus manual switch directly on the housing
• Fine, 4K/8K-ready matte white fabric (gain 1.1) with black back and black masking borders
• Sturdy, white powder-coated housing; the projection fabric is certified to fire rating B1

Is this screen the right choice?

• Yes, if there is no free power socket at the mounting location or you don't want to lay cables, for example in rented premises, in a conference room or above a whiteboard.
• Yes, if you want motorised convenience at the touch of a button with the same image height every time, without fixed wiring.
• A deliberate choice if your projector outputs 4:3 or you specifically want this image shape; with a pure 16:9 projector, a white strip would otherwise remain unused at the top and bottom.
• Not ideal if you use a laser TV or ultra short throw projector; for these you need a laser TV/CLR screen.
• Not ideal if very large viewing areas or consistently maximum flatness are the priority: in that case a tensioned screen with a lateral tensioning system ensures significantly better flatness.

Picture quality: fine matte white fabric for a clear, neutral image

The matte white projection fabric (diffusely reflecting, gain 1.1) reproduces colours neutrally and, with a sufficiently bright projector, delivers a sharp, bright image for Full HD, 4K and 8K content. Its wide dispersion ensures that the image looks evenly bright from side seats too. How punchy it looks with the lights on depends mainly on projector brightness and how well the room is darkened, as projector light and ambient light compete on the surface; a matte white fabric cannot actively suppress ambient light.

The black back reduces show-through from behind and keeps the picture clean; the black masking border all the way round frames the image and increases perceived contrast. When the screen is lowered, the weight of the bottom bar pulls the fabric smooth, ensuring an even projection surface.

Is it worth it compared with a white wall? As a rule, yes: a painted wall is rarely exactly neutral white and never completely smooth – its texture and colour tone blend into the image and cost sharpness and colour accuracy. The projection fabric, on the other hand, provides an even, precisely defined white and smooth surface; after the show, it disappears back into the housing. In a lot of ambient light, ambient light rejecting/contrast screens (ALR) get more out of the picture and deliver deeper blacks.

Will the battery screen fit your room? Dimensions and planning

Important before you buy: a screen needs more space than just the image width. The key details at a glance:

With this 4:3 format the black top drop is minimal (around 4 cm), so you can position the image height flexibly. Always extend the fabric fully if possible: its own weight pulls the surface flat and prevents waves.

As a rule of thumb, a comfortable seating distance in a home cinema for an image width of 280 cm is around 4 to 5.5 metres. In conference and training rooms, what matters most is that even the back row can read along comfortably – as a rough guide, the furthest seat should be no more than six times the image height away (here around 12.6 m). Our tip: mark out the dimensions on the wall with masking tape beforehand and you will see straight away whether the image size, image height and housing suit your room.

The screen is mounted on the wall or ceiling, hung via eyelets or firmly screwed in place (screws and wall plugs not included, as they depend on the surface); we recommend two people for installation. If the wall area is not clear, for example because of a shelf, a windowsill, a whiteboard or a TV, a matching celexon wall spacer from the Professional series creates the necessary distance from the wall.

Exactly where does the projector need to be positioned so that the image hits the screen precisely? That is the trickiest question for many people. Tell us which projector you have – we will plan the placement with you. Have your projector placement calculated →

Control: RF remote control and manual switch

The battery screen is controlled by RF remote control; it does not need line of sight to the screen and also works around corners over short distances. In addition, the fabric can be raised and lowered directly using a switch on the housing (left, viewed from the front); when ceiling-mounted, you can control it conveniently with the RF remote control.

Would you like the screen to lower automatically as soon as you switch on the projector? With the compatible celexon Professional radio set, it can be paired with the Professional wireless trigger: the trigger detects when the projector is switched on and lowers the screen automatically.

Applications

Presentations, conferences & training: Wherever a fixed electrical installation is awkward or not permitted (rented premises, listed buildings, changing locations or the wall above a whiteboard), the battery solution plays to its strengths. The screen fabric is certified to fire rating B1 (certificate), so the Professional Plus is also suitable for commercial and public spaces.

Home cinema & living room: a neutral, clean image for film and series nights, without visible cable ducts in the living room.

Format tip: If film and home cinema are your main focus, a 16:9 screen is usually the better choice – the black masking neatly frames the widescreen image and makes it more immersive. The 4:3 format is the right choice if you use a projector with the same format, mainly show presentation, training or document content, or want to use the image height flexibly.

How to keep your screen looking good for a long time

After use, the fabric disappears back into the housing; the flush bottom bar protects it from dust, touch and direct sunlight. For a permanently even surface, fully extend and retract the screen once at regular intervals and do not install it in a permanently warm environment – the PVC surface is sensitive to temperature.

A common idea: hanging the screen directly in front of a window. In direct sunlight, however, the fabric heats up there and may warp – so it is better not to place it directly in front of a sunlit window. Clean only with a dry or slightly damp soft cloth, never with alcohol or cleaning agents.

Frequently asked questions about the celexon battery screen Professional Plus

Do I need a power socket where the screen is mounted?
No. The screen runs on an integrated Li-ion battery and needs no power connection during operation. You only need a socket for charging – a 4 m charging power supply with charge indicator and multi-country plug is included; the charging socket is in the left end cap.

How long does a battery charge last?
With typical use, for example once or twice a day on a few days a week, a full charge lasts many weeks before you need to recharge; the charge indicator shows you the status. If required, you can also use the screen while it is charging.

Does the screen extend to the same position every time?
Yes. The motor stops the fabric at exactly the same position every time it extends. The image is therefore always at the same height, without you having to make sure of the correct extension length yourself, as you would with a manual pull-down screen.

Does the screen work with a laser TV or ultra short throw projector?
No. This matte white fabric is designed for conventional projectors with a normal throw distance. Laser TVs and UST projectors project from below at a very steep angle; for these you need special laser TV or CLR screens with a matching microstructure.

Can I use the screen in the garden or outdoors?
No. The battery screen is made for indoor use and is not designed to withstand wind and weather. For outdoor use, an inflatable outdoor screen such as the celexon INF Professional or a portable screen that you set up and take down is suitable.
