Tips & Tricks for Using the White Lightning SmartGPU (S28054 and S28114)
Designed to provide reliable power for aircraft systems during pre-flight checks and routine maintenance, the White Lightning SmartGPU has a variety of features and considerations to ensure smooth operations. To help you make the most of your SmartGPU, we’ve compiled a list of essential tips and tricks to optimize its use.
1. Connecting to Your Aircraft: A Simple Plug and Play
Getting our SmartGPU models connected to your aircraft couldn’t be easier. All models come with an 8-foot output cable equipped with a 3-pin oval AN2551 plug, making it simple to connect to your aircraft’s power system. Just plug it in, turn on your GPU, and you’re ready to power up your aircraft’s airframe systems.
2. Topping Off Your Aircraft Battery During Pre-Flight Checks
While the S28114 and S28054 SmartGPUs aren’t designed for long-term battery charging, they can be handy for topping off your battery in short bursts—especially during a powered pre-flight check. This allows you to check systems and lights without draining the starting battery. Keep in mind, though, that the GPU should only be used for this purpose when the battery isn’t severely discharged. For more thorough battery maintenance, the BMC24 Battery Maintenance charger kit will be coming soon (March 2025) for all SmartGPU models, and is designed for extended use that won’t overcharge your battery.
3. Charge Your Battery—But Only for Short Periods
If you need to “top off” a battery, the SmartGPU can provide a quick boost. However, for long-term battery charging and maintenance, use a purpose-built battery maintenance charge, available as an option for your SmartGPU (March 2025). The GPU isn’t built to monitor the battery’s charging status or adjust for environmental changes, so use it only for brief periods (around 1-2 hours). For more extensive charging needs, invest in a battery maintenance system that’s designed specifically for long-term care.
4. Worldwide Compatibility: Use Your GPU Anywhere
Traveling globally? Our SmartGPU models are equipped with a wide input voltage range of 90-264 volts AC and they support 47-63 Hz frequency, making them compatible with power grids around the world. The included AC cord is a North American 5-15P to C19 12GA, but it can be replaced or adapted with the right cord for local standards wherever you are. The BMC24 Maintenance Charger option is also compatible with international voltages.
5. Not for Engine Starting: Use for Airframe Systems Only
While our SmartGPUs are a great tool for powering the airframe electrical system, they are not designed to start aircraft engines—whether piston or turbine. Be sure to use them only for powering systems such as avionics, lighting, and other pre-flight checks, but not for engine starts.
6. Powering Aircraft Batteries: Play It Safe with Lithium and NiCad
If your aircraft is equipped with a lithium-ion or nickel-cadmium battery, rest easy—White Lightning GPUs are designed to power the airframe electrical system safely without charging the aircraft’s battery. However, if the aircraft’s battery is low, be sure to follow the manufacturer’s instructions for charging before using the GPU. Always verify the output voltage and current of your GPU to avoid exceeding the battery’s maximum charging rate.
7. The Best Way to Shut Down Your SmartGPU: Let It Cool Down
To keep your SmartGPU in top condition, follow proper shutdown procedures. After use, allow the unit to cool down before switching off. If the discharge air feels warm, take a short pause or disconnect the DC output cable, letting the unit run for an additional 3-5 minutes before powering down. This ensures longevity and optimal performance for the unit.
By following these tips, you can ensure that your White Lightning SmartGPU operates smoothly and lasts longer, providing reliable power for your aircraft’s electrical systems. Safe travels, and happy flying!
