How is battery disconnected for low cell voltage?
« on: September 04, 2012, 06:44:52 PM »
Hi Folks,

Dmitry noted in another post that the battery is disconnected when a cell voltage drops too low.   

Does anyone know how this is actually implemented in the hard ware? 

The reason I ask is two fold:

   My voltmeter  started showing  a 6 Volt drop in  battery output voltage when drawing 45 Amps, and I figure the key switch is probably failing.

   If the output is disconnected electronically, perhaps we can figure a way to turn it on and off from an external signal, and no longer use the switch function at all.  My Lyen controller uses an "ignition switch" function to turn it on, and I have a keyswitch mounted on the dashboard of my Morgen to turn on the motor and lights.  It would be nice to extend that function to the battery, and eliminate a seemingly common failure point.

TTFN,
Dennis
