  • Page 3 Why the BMC24 is Better Do not confuse the BMC24 Battery Maintenance Charger with trickle chargers or battery “tenders.” It is completely different. It is designed to gently charge aircraft batteries as completely as possible and then continuously maintain them at their maximum charge without overcharging.

  • Page 4: Important Safety Precautions

    7) Determine condition of battery by referring to instructions herein before attempting to charge or de-sulfate any battery. If the BMC24 reads a voltage of less than 4 while qualifying the battery, it reads as zero volts, and displays the message BATTERY NOT CONNECTED.

  • Page 5: Startup And Configuration

    Items Included with the SmartGPU BMC24 Option The following additional items are included with your GPU when equipped with the BMC24 option: ● Circuit board assembly, either factory-installed or easily customer-installed if purchased later. Installation instructions are provided separately, not part of this Operator’s Manual.

  • Page 6: Configuration Settings

    Select the number of days between charging, 0 to 30 days. 0 is the default value which provides continuous operation. Select the desired number of days between charge cycles. Note: If the battery voltage drops below 25 during scheduled or delayed charging, the BMC24 interrupts the schedule and starts a charging cycle.
  • Page 7 Configure Wi-Fi Using the App The easiest network setup involves the SmartGPU app. The SmartGPU app allows you to monitor and control both charging and GPU functions via Bluetooth or Wi-Fi. 1. Join a 802.11 b/g/n compatible Wi-Fi network on your mobile device. Make sure your network’s SSID is not hidden, and is broadcasting in 2.4 GHz (not 5GHz).

  • Page 8: Operation

    Operation The BMC24 Battery Maintenance Charger may be used immediately without custom configuring its settings and features. Doing so will assume commonly used default values that are safe and effective. However, the procedures above for tailoring the BMC settings to your preferences are quick, easy and recommended for optimum performance and convenience.
  • Page 9 Understanding the 7 Stages of Charging The BMC24 annunciates its active charging stage, temperature compensation, and desulfation status during operation. The chart above summarizes this unique approach to battery optimization and maintenance. ● Qualification begins the charging cycle by determining if the battery is correctly connected and has adequate voltage to attempt charging.
  • Page 10 The SmartGPU Mobile App The SmartGPU App mirrors the indications and controls of the SmartGPU display on your mobile device to monitor and control maintenance charging from anywhere with an internet connection. Wi-Fi is used for unattended, remote operation. Alternatively, Bluetooth connectivity is available for attended, local operation up to 100-feet.
