AeroTow Aircraft Tug Lithium Upgrade FAQ

Q1: Is this truly a "plug-and-play" replacement for my AeroTow tug, or will I need to cut wires and modify brackets?

• A: It is 100% plug-and-play. Our single-housing LiFePO4 battery is engineered with exact BCI Group U1/22NF dimensions and standard M6/M8 terminals. It fits directly into your AeroTow tray and connects using your original battery cables in under 10 minutes—no wire cutting, bracket modifications, or external balance leads required.

  
  

Q2: Will high-amp startup current or pulling over hangar door tracks trip the battery's BMS overload protection?

• A: No. Aircraft tugs demand high peak current when overcoming tire chocks or hangar door lips. Our customized BMS features a 5C surge capability (up to 300A for 3–5 seconds). This guarantees smooth, uninterrupted power during high-torque startups without annoying false BMS trips.

Q3: Can I use my original AeroTow factory charger, or do I have to buy a new one?

• A: You can use your original lead-acid charger for daily top-offs without damaging the battery. However, to achieve a 100% full charge in under 1.5 hours and ensure long-term cell balancing, we recommend using our dedicated LiFePO4 smart charger (available as a discounted bundle option).

Q4: AeroTow uses two 12V batteries in series. How does your "Single Pack" solution simplify my setup?

• A: Instead of buying and wiring two separate 12V AGM batteries in series (which creates internal imbalance and messy wiring), our True 24V (or 36V) Single-Pack puts all cells inside one sealed housing. You get a cleaner installation, zero wire resistance loss, and double the usable runtime.

Q5: Will dropping 20+ lbs of battery weight reduce traction on my AeroTow’s drive tires?

• A: Zero traction is lost. AeroTow’s nose-gear engagement mechanism uses the weight of the aircraft itself to press the drive tires onto the ground. Shedding dead battery weight actually reduces strain on your tug's motor and drive gear while making physical handle maneuvering effortless.

Q6: What happens if I forget to turn off my AeroTow switch and leave it in the hangar for weeks?

• A: Left on, standard AGM batteries drain to 0V and ruin permanently. Our Smart BMS includes Low-Voltage Auto-Cutoff. It automatically disconnects power before deep-discharge damage occurs, preserving 100% of your battery health. Simply plug in the charger to reactivate it.

Q7: How does this lithium battery perform in unheated winter hangars?

• A: Lead-acid batteries lose over 40% of their power in freezing temperatures, causing sluggish towing. LiFePO4 delivers stable voltage down to -4°F (-20°C). For extreme sub-zero climates, select our Integrated Self-Heating Version, which automatically warms the core before charging.

Q8: What is the exact ROI and service life comparison compared to OEM AGM batteries?

• A: OEM AGM batteries last 300–500 cycles (1–2 years) before degradation. Our Grade-A LiFePO4 pack yields 8,000+ deep cycles (10–15 years of service). Upgrading eliminates 3 to 4 AGM replacement cycles and preventing unexpected towing failures.

Q9: Is this battery safe to transport inside my aircraft cabin if I fly with my portable AeroTow?

• A: Yes. Our LiFePO4 battery is completely dry, leak-proof, non-gassing, and fully certified under UN38.3 aviation transport standards. It is 100% safe to pack inside your airplane's luggage compartment alongside your foldable AeroTow tug.

Q10: What warranty and technical support do you offer for commercial and private aviation users?

• A: Every AeroTow-compatible lithium pack comes backed by our 5-Year （up to 10years) Commercial Replacement Warranty. We provide direct US/EU technical support, zero-hassle warranty service, and dedicated assistance for hangar managers and private aircraft owners.
