-Amazon sells 12V 12Ah gel cells for about $30, such as ExpertPower EXP12120
+replace USB connector with a version that has actual slow primitive (which
+means moving to latest pcb-rnd 4-layer template)
 
-add 8-position DIP switch to select bank 1-8.  if all switches off, firmware
-will take over and use value in flash (allows for high bank numbers)
+fix the short that's apparently been there a while?  v_lipo to ground?
 
-add more mounting holes so board doesn't flex when changing spade terminals
+possibly thermally relieve the battery negative 0.25" spade
+
+pull resistors away from through-hole LEDs to ease lead trimming

+- on all units shipped to date with INA180A4IDBVT, the max current the current
+  sensor can read and stay within 3.3V ADC input range is 16.5A.  The intent
+  was for the full scale range to be 150A, but that would require the A1 part
+  not the A4 part!  We may be over-voltaging that ADC input on existing 
+  product in the field during drag-race conditions?
+
+  Let's just eliminate the current sensor entirely for future production runs
