MBW ScreeDemon WS500M Screed Drive Unit - Battery
The ScreeDemon™ WS500M is a battery-powered new generation and more environmentally-friendly professional walk behind vibratory wet concrete screed.
It is designed for use with a choice of 7 interchangeable custom-made screed beams. Available beam lengths range from 1.2 to 4.88m.
The WS500M is significantly quieter and cheaper to operate than its petrol counterpart, the ScreeDemon™ WS500H (Honda GX35 4-Stroke petrol engine) and is also more ideally suited for use virgin sites, indoors and in poorly ventilated areas as it does not exhaust hazardous fumes. It is also equipped with LED lights that help improve visibility in dimly lit work areas.
For added convenience it is designed for use with the same Milwaukee M18 Lithium-ion batteries used to power a wide variety of Milwaukee products that many tradespeople will already own and use - with battery run times similar in duration to that of a tank of fuel, at the fraction of the equivalent cost.
The WS500M can be purchased as a drive unit only, or in a kit form (WS500M-Kit) which also includes the supply of:
1 x M18 5A battery, 1 x M18 12A battery, 1 x charger and 1 x carry bag.
ScreeDemon™ WS500M Drive Unit (Battery) - 18V Li-ion Battery. Beam range 1.2 to 4.88m. 13kg*.
Designed for use with Milwaukee M18 18V Li-ion batteries.

The Li-ion battery powered ScreeDemon™ WS500M offers all the attributes of its petrol counterpart (the WS500H), with the advantages and convenience of being powered, with substantially lower operating and maintenance costs, without sacrificing product performance.
| Battery Power | Run Time at Full Throttle | Recharge Time |
| 5Amp (Ah) | 27 minutes | 49 minutes |
| 12Amp (Ah) | 65 minutes | 120 minutes |
As with all batteries, cold weather can have an adverse effect on performance. Other variables can also affect associated run times too. In order get an operating run time in the region of 2 hours we recommend using the 5AH battery first (which will run for circa 27 minutes on full throttle). Once the charge of the 5Amp battery is depleted, replace it with the 12Amp whilst the 5Amp battery is placed on charge (and so forth and so on).
The battery-powered WS500M is a credible alternative to conventional petrol-powered wet screeds and is more ideally suited for indoor use and use in poorly ventilated areas. It is also ideal for use on virgin sites as well as general site use, thanks to its cordless and unrestricted use.
ScreeDemon™ beams are made from magnesium which is lighter, more rigid and less reactive with concrete than aluminium. They have a unique back-to-back triangular construction, which increases their strength and rigidity, as well as minimising the variability in the transmission of vibration along the entire beam length.
Some competitor models use bolts to attach their beams/blades to their screed drive unit. The ScreeDemon™ is designed to assemble and disassemble in seconds and has a different beam design and mounting arrangement which facilitates this.
The bolt arrangement used on many other competitor screeds to mount their beams/blades is often prone to the associated hardware threads becoming compromised through contact with wet concrete, making assembly, dismantling and interchanging beam lengths and blades more time consuming and problematic. The ScreeDemon™ clamping system is designed to eradicate this and furthermore means that beams which are free from holes and/or cut-outs which also can weaken their structural integrity. It also enables ScreeDemon™ beams to be mounted offset to the drive unit, thereby making it easier to navigate around obstacles and under protrusions. ScreeDemon™ beams because of their unique design can also often be shortened and reused as they wear (which invariably at their ends caused by the constant friction caused with being in contact with formwork). This is in contradiction to most other competitor blades and beams which are simply discarded and worn away due to wear.
