Concorde aerobatic RG® Series recombinant gas batteries are constructed with advanced sealed lead acid technology and unique features such as additional PolyGuard® separators around the plates to protect against shock and vibration, and larger than the industry standard intercell connections for optimal outrush and increased charge acceptance.
The battery is housed within an aluminum container and cover. A hold down bar is integrated into the cover with a lifting strap fitted on the cover.

Designed to float directly on the DC buss which provides high inrush current resulting in fast recovery time and extended battery life. Concorde batteries are self regulating and will accept only the current required to maintain charge. There is no need for a dedicated charger.

The RG-145-2 is designed for enhanced cold weather performance. Heater blankets are interwoven between the cells and operate when the battery temperature drops below 60°F improving cold weather performance.
