To recharge the unit, simply plug it into an AC wall power outlet and leave it plugged in when not in use.  The high tech proprietary chargers will maintain 100% battery charge without over charging the batteries.  Avoid fully discharging the batteries as damage to the cells may result.  Built with the only cost effective, patented Quick Change design in the world, the batteries in this unit can be easily changed in a matter of seconds without tools, training, or downtime.

The environmentally responsible, low VOC powder coating protects the case from wear, tear and poor weather conditions.  Additionally, an all-weather cover accessory is available as an option to protect it further from inclement weather maximising performance and product life.

NOTE  When using more than 400 continuous amps, the batteries will make up the difference until they become depleted.  On most aircraft, a low voltage relay will drop the GPU offline when the voltage drops below a preset level.  Unfortunately, the GPU’s voltage will then rise back up, causing the aircraft to make use of it once more.  This, in turn, will cause it to re-drop below its preset level, creating a vicious circle.  It is this oscillation that can cause damage to aircraft components.
