Emergency Ventilation Portable firefighting fan BATFAN 20 Cordless battery power

Description

This is a new unit that got damaged a bit in shipping.  The front handle mounts got bent and the position lock was bent and broke.  I was able to get about 90% of the front bar straightened out and I installed a new position holder.
I have tested the unit multiple times to test the battery.  Battery seems to last about 22 min at 75% power.  A test I just did lasted 21:20 at 100%.  Although that is better than the rating it seems that at lower power it still only lasts in the 20 min range.  I don't know exactly what that means, but that is the hard data I have on this unit.
This thing creates alot of air movement.
