SmartGPU Battery Maintenance Charger Kit (BMC24)

The BMC24 is a highly specialized multi-stage battery charger calibrated specifically for the unique characteristics of lead-acid aircraft batteries. It is not approved for any other use. It incorporates award-winning BatteryMINDer technology and is offered as a convenient option for our SmartGPU Series of Ground Power Units for general aviation aircraft. The charger option can be ordered factory-installed in a SmartGPU, but this kit makes it easy to upgrade your SmartGPU with minimal tools and technical experience. A printed installation manual is included, and a video tutorial is available here.

The following additional items are included with the BMC24 Kit:

• Circuit board assembly (the charger unit).

• Printed installation instructions (with a QR code to the installation video)

• 8 ft. output cable with handles and red SB50 plugs – Connects between the charger output and the mating plug on Model BM-AIK10A airframe battery harness.

• Airframe Interface Kit (Model BM-AIK10A) – all the parts needed to install a fuse-protected battery maintenance charger harness on your aircraft. 

Features

The BMC24 Battery Maintenance Charger is not a simple trickle charger or battery “tender.” It is designed to gently and precisely charge aircraft batteries as completely as possible and then continuously maintain them at their maximum charge without overcharging. 

Double Your Battery’s Life

With continuous use, the BMC24 with BatteryMINDer technology can actually reverse sulfation and the typical battery aging process. Pulse desulfation will restore lost capacity and significantly extend the useful life of aircraft batteries. The BMC24 is designed and intended for full-time continuous-duty use. It is recommended that it be kept connected whenever the aircraft is in hangar storage to maintain and condition the battery.

Convenient Airframe Connection

The BMC24 is supplied with a Model BM-AIK10A Airframe Interface Kit which contains the aviation-grade parts and instructions necessary for a FAA-licensed mechanic to install a simple wiring harness to conveniently access and charge the battery on a certified aircraft. This harness provides a mating polarized plug for quick connection to the aircraft battery. It is eligible as a minor alteration and the mechanic’s airframe maintenance logbook entry is all that is required to return the aircraft to service – it does not require an STC, Form 337, or field approval.

Set It and Forget It

Consistent use of the Battery Maintenance Charger will provide extended battery life, maximum starting power (especially important for cool turbine engine starts) and full emergency power for every flight. Once charging is initiated, the BMC24’s design requires no input from the operator and automatically resumes operations should a power failure occur. Operation is completely automatic. To prevent over or undercharging, the aviation BatteryMINDer automatically adjusts its output in response to variations in ambient temperature. There are user configurable settings if initial charging delay or scheduled charging is desired.
