Product Q&A

Q:Q1: Can this generator charge my lithium battery while the tricycle is moving?

Yes. This range extender generator is designed for real-time onboard charging it can charge your lithium battery while driving. Simply start the generator, and it delivers stable DC power directly to the battery, extending your range without stopping.

Q:Q2: How do I choose between the 3KW, 4KW, and 5KW models?

It depends on your tricycle's battery capacity and daily workload. For light-duty urban delivery with smaller battery packs, 3KW is sufficient. For heavy cargo hauling or larger battery systems, 4KW or 5KW provides faster charging and better performance. Contact us with your battery specs for a precise recommendation.

Q:Q3: Does this generator support all three voltages automatically or do I need to switch manually?

It supports 48V, 60V, and 72V systems. Depending on the model configuration, some versions feature automatic voltage detection while others use a manual selector switch. Please specify your battery voltage when ordering so we can pre-configure the unit for your system.

Q:Q4: What is the fuel consumption and how far can it extend my range?

Fuel consumption is approximately 0.5-0.8 liters per hour depending on the power output and load. A full tank can provide 6-8 hours of continuous charging, effectively doubling or tripling your electric tricycle's range enough for a full day of deliveries.

Q:Q5: What is the MOQ and do you provide after-sales support?

MOQ starts at 10 units for trial orders. We provide a 12-month warranty, spare parts availability, and technical support via video call or message. OEM branding and voltage customization are available upon request.
