  Battery requires monitoring and periodic change like controls

  BSM8-USB (New)

• Same board as BSM7 but with no battery
• BS8 wedge form factor (like a BSF8 control)
• The good: Powered 100% by computer's USB port
  No battery to monitor, replace, or die
• The tradeoff: No battery backup in loss of power / if unplugged
  The BSM7 can continue to download when not plugged in
• Both the BSM7 and BSM8 have backup memory onboard
• The BSM7 as primary unit is still recommended, add BSM8 if desired
