Uh, no, I would build one from my 'junk box.'
Specifications: - zener reference voltage
- setable "cut out" voltage - trim resistor adjusts the cut out, once set, the battery is disconnected
- setable "engage" voltage - second trim resistor adjusts the higher, enable voltage so the battery voltage rise from no load won't trigger oscillation.
- enable line - tied to ignition, it enables the deep storage battery. Breaking enable line, disconnects the deep storage relay.
- diode protected relay engage drive - (old school), optional MOSFETs
Actually it would be more fun to build an integrated system that includes the charger and a buck regulator to . . . <GACK> stop NOW!
