Concorde Battery has developed a new lighter weight aircraft battery for turbine applications. The new RG-325 is 25 AH and FAA-TSO authorized. RG-325 was specifically constructed for turbine starting applications with the goal of a lighter weight, durably constructed battery that could sustain multiple turbine engine starts. With this in mind, rather than designing the battery with the typical heavy MS3509 receptacle that also requires a heavy Quick Disconnect connector, it was designed with brass M8 terminals for lighter weight ring terminal connections. This weight reduction also results in cost savings due to the high cost of the MS3509 receptacle.

RG-325 is constructed with Concorde’s same proven technology of robust plates, larger intercell connections for less internal resistance and proprietary PolyGuard® separators (an additional layer of protection against shorts that is unique to Concorde). As with all of Concorde’s RG® Series batteries, RG-325 is maintenance free (doesn’t require the addition of electrolyte or water), aerobatic and factory tested to assure airworthiness and installation readiness. RG-325 has also passed the rigorous requirements of TSO testing to obtain FAA-TSO authorization.

Concorde Battery is pleased to announce Robinson Helicopter Co. has selected the RG-325 for the R66 Turbine helicopter.

Editor note.  We understand this is Robinson part number B237-8 and adds a weight of 10 pounds over the standard battery weight.  Robinson price the option at US $2,200 for field installation, or US $900 exchange on new aircraft orders.  We are also surprised that Concorde have not waxed lyrical about the new option being 24V with 25 Amp Hour and mounts in the same location as the standard 24V 19 Amp Hour battery.  We understand no extra hardware is required
