[ausev] Trike conversion: Circuit Question.

[jtp]

With a "Passing Battery", I would be looking for some exceptional
acceleration boost only several times a week or month.

While Erik has an excellent point in the controller not probably designed
for the surge,  the idea for the DC to DC converter to rebound the battery
would be a factor.
 While this would be more of a safety/performance type of consideration, my
concern would be the momentary interruption of power at 96 volts to go to
108 volts for the controller.
  In addition,  If the 12 volt auxiliary battery were isolated further from
a smaller "contactor holding/Headlamp-high-beam-ON- brighter-as-warning
battery"  (I know this may sound rather over-complex in design, but I am
aiming for quite a nice set of refinements with these questions),  I see
typically an expectation of only several "booster-stage- voltage events" per
week at very most.  This is especially worth consideration since a
motorcycle has no "Packaging", or, a body of metal surrounding you for lots
of safety.   A "Passing Battery circuit", if in fault, would default resting
in "normal operation".
