    With the vastly improved reliability of servos and receiver due to advent of surface mount technology, the overwhelming majority of non-thumb induced crashes are a consequence of failure of the battery pack and switch sub-systems. This 6.0VDC 5-cell NiMH battery pack aims to increase reliability by two techniques. First, by adopting the most stable and reliable battery chemistry and configuration. Second, by effectively reducing current flow through the connectors in half.

    This battery pack is typically used for powering the onboard control electronics, or avionics, of a remote control model. E.g. the receiver and servos. By relying on nickel-metal hydride chemistry, it offers the reliability of the most proven chemistry packaged in the 5-cells in series configuration. This provides a clean and steady source of 6.0V (nominal) direct current (DC). This is the most reliable battery technology and it's been around for decades. It is the defacto standard in sales of brand new radio systems as supplied by the major manufacturers, e.g. Futaba, JR, Spektrum, Hitec, and Sanwa/Airtronics.

    This pack is equipped with two JR-style plugs instead of one because of the tendency toward ever increase current drain by the on-board avionics of today. Basically, by using two battery connections to the receiver you cut in half th amount of current going through either for added reliability.

    To improve reliability further, instead of relying on one JR-style universal connector (0.10" standard spacing), the battery pack comes with two. While you can use it with just one by leaving (just the second one dangling, perhaps to use as a convenient place to monitor battery pack voltage), optimal use is made by employing both connectors to the receiver (with two switches) because this effectively cuts in half the current flow through any one connector. This greatly reduces heat and overall resistance to current flow thus optimizing reliability of the connection sub-system. Adding further to this, there is a benefit in switch subsystem reliability by using two switches instead of one (thereby gaining redundancy).

    Bottom line? Experienced modelers prefer the stable, familiar, and proven technology of NiMH chemistry packaged in 5 series cells with the improvements on competing packs of dual connections that reduce current flow through each connector will dual switches add another layer of protection when employing two switches for redundancy.
