   I never was employed doing destructive testing, but I did spend a decade   
   or two doing low voltage communication contracting.  I learned there is   
   what they say, and there is what there is.  Usually what they say fell   
   short in my field, but sometimes it didn't.   
      
   When they say an IR motion sensor will detect motion at 90 feet they   
   mean if ambient is below 70F and the subject is large and is running a   
   fever.  LOL.  They don't say if ambient is 90+ its virtually worthless.   
      
   Seriously there are thousands of bass boats that don't have room for 4   
   big deep cycles batteries running just three in series for the 36V TM   
   and tapping the positive of the ground battery for nominal 12V for   
   cranking and accessories.  The big thing is to charge as soon as they   
   cool down (or get back to the hotel), and to have three equal batteries.   
      
   With most pros running 20-23 foot glitter barges these days most have   
   plenty of room in the back for batteries, but some older boats and/or   
   smaller boats didn't.  Many have also switched over to a single high   
   voltage lithium for their TM battery for motors upto 48V.  I wonder how   
   they do on the Potomac in a winter tournament before sunrise when the   
   water gels on the line and freezes in the reel.  The lead acid deep   
   cycles would work.  Something has to keep the lithiums from dropping to   
   ambient temperature.   
      
   Anyway, this is all tangent of tangent now.
