The Li-ion battery powered WS500M ScreeDemon™ offers all the attributes of its petrol powered counterpart, with the advantages of being battery powered, without sacrificing performance and at a fraction of the associated operating costs.

The data above is not a guarantee of expected performance, but rather has been created to provide indicative run times with expected associated recharge times.

For test purposes, the machine was mounted onto a 10ft (3m) beam and was run with throttle at 100% on a vibration test mat. The batteries were fully charged prior to testing, and the throttle was kept at 100% until the machine stopped. Batteries were then recharged until completely full.

As with all batteries, cold weather may have an adverse effect on performance. Other variables can also affect associated run times too. In order to get a run time in the region of two hours, we recommend using the 5Ah battery first, which will run for around 27 minutes on full throttle. Once the charge on the 5Amp battery is depleted, replace it with the 12Amp battery whilst the 5Amp is placed on charge (and so forth and so on).
