[NSRCA-discussion] CA Models Eclipse

[Jerry Stebbins]

That depends on how you interpret the "Requirement". ALL batteries are 
marketed and sold at their advertised cell voltage-not at their "fully 
charged" peak value. That (fully charged) is what the interpretation value 
someone has defined is based on. I am researching and find NO BASIS for the 
value in the Rules. NEC and safety codes work more around 48v (rated battery 
value) ie a car battery is a 12 volt battery -it so happens to nominally run 
13.6v at full charge-. I am working on a potential rule change to set the 
value somewhere (with justification) around 48plus volts and also based upon 
advertised cell ratings-like all other batteries are sold.That would allow 
new cell chemistries at comperable total wattage ratings, in the tent, and 
leave some room for some others that are being worked on for vehicle use.
