The 8 questions overseas buyers ask us most
Before we talk about products, here is what importers, fleet managers and drivers usually worry about when buying electric vehicles from China — and what we do about each problem.
Why do electric tricycle batteries die after one year?
Most early battery failures come from four causes: deep discharge, heat, overloading and a charger that does not match the battery. In daily commercial use a lead-acid pack typically lasts 12–18 months, while a LiFePO4 lithium pack usually lasts 3–5 years. We match battery, BMS and charger at the factory and quote both chemistries so you can compare the 3-year cost.
Battery options & real lifespanIs the advertised range real?
A range figure means nothing without its conditions. Range falls with load, speed, gradient, headwind and temperature, often by 30–50% between an empty test and a loaded working day. Every range we publish states the test load, average speed, route and temperature, and you can ask for the test sheet of any model before ordering.
How we test rangeWill it climb hills fully loaded?
Hill performance depends on torque at the wheel, not the motor wattage on the brochure. For hilly routes choose a model with a geared differential rear axle, a controller sized for the motor and hydraulic brakes for the way down. We publish the loaded climbing gradient measured on our own test slope for each heavy-duty model.
Heavy-duty & hill modelsCan I get spare parts after I buy?
Yes. Every vehicle comes with a spare parts list and exploded diagrams with part numbers, so parts can be identified from a number or a photo, and urgent items ship by air or express. With every vehicle order we recommend a first-year parts kit sized to your fleet, so vehicles are not parked for weeks waiting for a controller or a brake shoe.
Our spare parts guaranteeHow do I know you are a real factory?
Ask for a live video tour of the production line, check our business licence and export registration, and send your own inspector before paying the balance. Our company name, factory address, official email domain and single bank account are published on one verification page, so anyone contacting you in our name can be checked.
Verify JolmolangmaWhat about rain, heat and unstable power?
Vehicles for tropical markets get sealed connectors, raised controller mounting and a water spray test. For hot climates we manage battery temperature and recommend LiFePO4. For unstable grids we supply wide-input chargers with surge protection, or solar charging, so voltage spikes do not destroy chargers and on-board electronics.
Choose the right configurationHow much does it cost to import, and what about duty?
Landed cost is the ex-works price plus packing, inland freight, ocean freight, insurance, import duty, VAT, clearance and local delivery. Duty on fully built vehicles is often higher than on SKD or CKD kits, and SKD/CKD packing also fits more units per container. We quote every line separately and confirm loading quantities for your model.
Import cost step by stepDo your chargers work with my cars and my software?
Our chargers range from 3.5 kW to 360 kW and are built to IEC 61851 and IEC 62196. Tell us the vehicles (CCS2, Type 2, GB/T or CHAdeMO), your grid supply (single or three phase) and your back-office platform, and we confirm connector, power and OCPP compatibility before you order.

How to choose an electric cargo tricycle: 7 steps
To choose an electric cargo tricycle, start from the job, not the price: define your real daily load and distance, check the hills on your route, pick the battery chemistry by total 3-year cost, match the body to the cargo, confirm brakes and axle for the load, check parts availability in your country, and verify the supplier before you pay.
- Measure the real load. Use your heaviest normal trip, not your average — and add 20% margin. Overloading is the first cause of cracked frames and broken axles.
- Measure the real distance. Daily kilometres plus a 25% reserve for detours, traffic and battery ageing.
- Check the steepest hill. Above roughly 10% gradient with a full load, choose a geared differential rear axle and hydraulic brakes.
- Choose the battery by 3-year cost. Lead-acid is cheaper on day one; LiFePO4 is usually cheaper by year three for vehicles that work every day.
- Match the body to the cargo. Open body for bulk goods, closed box for parcels and rain, insulated or refrigerated for food and medicine.
- Plan for spare parts. Order a first-year kit with the vehicles; confirm how fast the supplier ships controllers, chargers and brake parts.
- Verify the supplier. Video factory tour, company documents, one bank account, and an inspection before the balance payment.
Lead-acid vs LiFePO4 for electric tricycles
For a tricycle that works every day, LiFePO4 lithium usually costs more to buy but less to own: it lasts roughly 3–4 times as many cycles, weighs about half as much and keeps its range in hot weather better than lead-acid.
| Factor | Lead-acid | LiFePO4 lithium |
|---|---|---|
| Typical cycle life* | 300–500 cycles | 1,500–2,500+ cycles |
| Typical life in daily use* | 12–18 months | 3–5 years |
| Weight for same energy | Heavier (≈2×) | Lighter |
| Charging time | 8–10 h typical | 4–6 h typical |
| Heat tolerance | Ages fast above 35 °C | Better, with BMS protection |
| Purchase price | Lower | Higher |
| Best for | Light, occasional use, tight budgets | Fleets, taxis, daily commercial work |
*Typical industry ranges at 80% depth of discharge. Actual life depends on heat, charging habits and load. Model-specific test data is available on request.
CBU vs SKD vs CKD: which way to ship?
| Shipping form | What arrives | Units per container | Best for |
|---|---|---|---|
| CBU | Fully built vehicles | Lowest | First orders, small dealers |
| SKD | Major assemblies, final assembly locally | Higher | Dealers with a workshop |
| CKD | Parts and sub-assemblies | Highest | Local assembly plants, lower duty markets |

4 formulas every electric vehicle buyer should know
You do not need to be an engineer to check whether a supplier’s numbers make sense. These four formulas are the ones our engineers use every day. Each comes with a worked example you can repeat with your own figures.
1. How much power does a hill need?
m = total mass (vehicle + load, kg) · g = 9.81 m/s² · v = speed (m/s) · θ = slope angle · Crr = rolling resistance (≈ 0.015–0.02 on paved roads) · η = drivetrain efficiency (≈ 0.8).
2. How big a battery do I need?
Usable depth of discharge is about 0.9 for LiFePO4 and about 0.5 for lead-acid if you want it to last. A loaded three-wheeler typically uses 50–110 Wh per km depending on weight, hills and speed.
3. How long will charging take?
Charger efficiency is typically 0.88–0.95. For lithium batteries the last 10–20% charges more slowly, so real time is a little longer than the formula for a full charge.
4. What does a vehicle really cost me?
The total cost of ownership (TCO) is the number that decides whether electric pays. Comparing only purchase prices hides the two biggest costs of a working vehicle: fuel and batteries.

Electric vs petrol tuk-tuk: how to calculate your savings
An electric tuk-tuk saves money when its daily energy cost plus battery replacement cost is lower than the petrol and engine maintenance cost of the vehicle it replaces. For most drivers covering 80–120 km a day, the savings come mainly from fuel and from far fewer moving parts to service.
| Illustrative example (your numbers will differ) | Petrol tuk-tuk | Electric tuk-tuk (LiFePO4) |
|---|---|---|
| Daily distance | 100 km | 100 km |
| Energy used | ≈ 4 L petrol | ≈ 8 kWh electricity |
| Assumed price | USD 1.00 / L | USD 0.15 / kWh |
| Energy cost per day | ≈ USD 4.00 | ≈ USD 1.20 |
| Oil, filters, clutch, engine repairs | Regular | None (motor has no oil or clutch) |
| Battery provision | — | Set aside a monthly amount for eventual replacement |
Assumptions are for illustration only; fuel use, electricity tariffs and prices vary widely by country. Put in your own numbers with our TCO & payback calculator.

Why LiFePO4 usually wins for vehicles that work every day
A battery is considered worn out when it can store only about 80% of its original capacity. Typical lead-acid traction batteries reach that point after roughly 300–500 full cycles; typical LiFePO4 packs after roughly 1,500–2,500 cycles. A tricycle that works six days a week uses about 300 cycles a year.
That is the whole story in one number: 300 cycles a year. A lead-acid pack can be finished within its first or second year of commercial work, while a good LiFePO4 pack can last the working life of the vehicle. Heat makes the gap larger, because lead-acid ages much faster above 35 °C. This is why we recommend lithium for taxis, delivery fleets and any vehicle used daily in hot climates, and why we still offer lead-acid for light, occasional use where purchase price matters most.
- Ask every supplier for the cycle life and the depth of discharge it was measured at
- Ask which cell maker is used and whether the BMS balances cells
- Ask whether the charger is matched to the battery chemistry
Illustrative curves based on typical industry ranges at about 80% depth of discharge and 25 °C. Real results depend on cell quality, temperature, charging and load.
Lead-acid or LiFePO4 over the years
Battery purchases by cycle life over the life of the vehicle.
Relative scores from 1 (weak) to 5 (strong), based on typical characteristics of each chemistry. “Purchase price” scores higher when cheaper.
Lead-acid vs LiFePO4 across six factors that matter to operators
LiFePO4 outperforms lead-acid on cycle life, weight, charging speed, heat tolerance and usable capacity; lead-acid wins only on purchase price. For vehicles that work every day, the five lithium advantages usually outweigh the one lead-acid advantage within the first two to three years.
- Cycle life — the single biggest factor in total cost
- Usable capacity — lead-acid should not be discharged below about 50%
- Weight — every kg of battery is a kg of cargo you cannot carry
- Charging speed — shorter charging means more working hours
- Heat tolerance — critical in Africa, the Middle East and South Asia

What more than a decade of exporting electric three-wheelers has taught us
Buyers ask about range; vehicles fail from overloading, water and bad charging
Almost every first inquiry we receive asks “how many kilometres?” Yet when we analyse warranty claims, very few relate to range. The failures that actually park vehicles are cracked frames and broken axles from loads far above the rating, controllers and connectors damaged by water, and batteries killed by the wrong charger or by being run flat every day. That is why we ask about your load, your roads and your rainy season before we recommend a model — and why we will tell you when a cheaper light model is the wrong choice for your work.
The battery is the most expensive part of the vehicle’s life, not the frame
Over three years, a working tricycle on lead-acid batteries may need two or three replacement packs. Fleet owners who compare only the ex-works price often discover this in year two. We quote vehicle, battery and charger as separate lines precisely so that the battery decision is made with open eyes. For vehicles that work every day, we usually recommend LiFePO4; for light, occasional use, lead-acid can still be the sensible choice.
What customers fear is not a high price — it is a vehicle standing still
A distributor can sell a slightly more expensive vehicle. What destroys his reputation is a customer waiting six weeks for a controller. This is why every vehicle order comes with a recommended first-year parts kit, a parts list and exploded diagrams. When a dealer tells us “your parts arrived in five days”, that is worth more to our next order than any discount.
The first order is almost always a test — and it should be
Serious importers start with one to five vehicles, drive them on their own streets for a month, and then order containers. We encourage this. A supplier who insists on a full container before you have seen the product is asking you to carry all the risk. Our sample policy exists because our best long-term partners all started small.
High-duty markets move to local assembly — plan for it early
In many countries, import duty on fully built vehicles is higher than on kits, and a container of CKD parts carries far more units. Distributors who grow usually end up assembling locally. We design packing lists, jigs and assembly training for SKD and CKD from the start, so that moving from CBU to local assembly does not mean changing supplier.
Chinese EVs are selling abroad faster than their after-sales networks
Chinese electric cars are now common on roads far from China, but workshops in many of those markets still struggle to find the right part. A VIN-matched part that arrives in a week keeps a taxi on the road; a wrong part costs two weeks and a return shipment. That gap is why we built our Chinese EV parts catalogue by brand, model and system, and why we label every part as genuine, OE or aftermarket.
Honesty about limitations wins more business than exaggeration
Buyers now check what suppliers say against other websites, videos and AI assistants. A range claim that fails on the first loaded trip loses the customer and everyone he talks to. We publish test conditions, say which models are unsuitable for which jobs, and put our company details where anyone can verify them. It costs us a few inquiries from people looking for the lowest number; it earns us the customers who reorder.
What does overloading cost in bearing life?
Rolling-bearing life falls with the cube of the load (ISO 281).
