Technical Questions Overseas Buyers & Distributors Ask First
Comprehensive engineering clarity regarding electrical loads, warranty terms, installation architecture, and shipping logistics.
How does installing overhead fans affect the overall driving range of a 72V lithium golf cart?
Negligibly. Our integrated brushless DC fan modules draw approximately 15W to 25W per unit at maximum velocity. Running dual fans over an 8-hour operational shift consumes under 0.4 kWh of energy. On a standard Leibin 72V 105Ah LiFePO4 battery pack (storing approximately 7.56 kWh), the fan system expends less than 4% of total battery capacity over an entire day of non-stop operation, preserving 100+ km of driving range intact.
Why is a dedicated DC-DC converter mandatory instead of connecting the fan directly to a single 12V battery cell?
In traditional 48V (four 12V batteries) or 72V (six 12V batteries in series) lead-acid systems, tapping a single 12V battery causes asymmetric discharge. When recharged, the other batteries become overcharged while the tapped battery remains perpetually undercharged, triggering battery boiling, cell reversal, and premature pack failure within 3 to 6 months. Leibin's factory architecture draws power across the entire series voltage bank through an isolated DC-DC converter, guaranteeing perfectly balanced cell life.
Can overseas golf courses and fleet dealerships order customized branding and mounting brackets (OEM/ODM)?
Yes. As a direct manufacturing entity in Dezhou, Shandong, we offer extensive OEM/ODM configuration. This includes custom molded strut clamps that match OEM roll-cage profiles (Club Car, EZGO, Yamaha, or Leibin platforms), laser-etched resort logos, custom color-matched housings, and integrated LED reading lights or USB charging hubs directly embedded inside the fan housing.
How are electric vehicles and sensitive electronic fan systems packaged for ocean container transport?
Vehicles are secured in heavy-duty welded steel-frame crates (SKD semi-knocked down) or rolled directly into 40ft High Cube containers via specialized vehicle lashings. Auxiliary electronic fans, solar controllers, and dash screens receive moisture-proof VCI anti-corrosion barrier wrap and desiccant packs to withstand up to 45 days of ocean transit through humid equatorial sea lanes.
