  The board is designed to take 12 volts input. The higher amperage voltage will cause the heat sinks to get warmer, not the battery. The higher amperage input decreases the charging time.

  Don't you mean the higher voltage will cause the heat sinks to get warmer?

  Jim. You are correct. I corrected my post. I was reading this as I was writing.
  

  Connect a “center positive” 2.1mm wall transformer (such as Parallax #750-00009) to the
  Charging Power Input jack as noted in Figure 3. The power supply should have a voltage output
  between +5 VDC and +12 VDC. The amount of current necessary to charge the cells is
  controlled automatically by the circuitry; however your wall transformer should be rated at 1 amp
  or more to minimize charging time. If the charging current supply is too low, the charging
  circuits may not operate. In addition, a lower current will not harm the cells; they’ll just take
  longer to charge.

  Thanks, so it's mostly the board that takes the brunt of faster charging, not the cells.
