This page removes the three fears behind every export order: return freight that costs more than the battery, a claim that drags on for half a year, and nobody to call when a pack fails. Assessment standards are published in full, backed by local replacement and in-house consumable repair.
verifiedRemote 4G IoT plus host-software logs — no dismantling and no return shipment · direct release from bonded stock at seven hubs
Specification notice:Reference values only — batch and duty-cycle variation applies. Contact us for detailed specifications.
Remote data streaming, precise on-site measurement and national-level laboratory arbitration combine to keep every after-sales decision transparent and tamper-proof.
Quality engineers run a full inspection of the suspect module with digital calipers and an insulation tester, then issue an authoritative third-party analysis report identifying the real cause of wear.
Tolerance ≤ 0.02mmFault-instant voltage delta, cell temperature distribution and charge/discharge rate curves are read remotely without opening the pack, so engineers issue an accurate liability decision in 15 minutes.
Millisecond fault replay in the cloudCore overseas bonded warehouses hold original BMS boards, high-current connectors, fuses and relays, dispatching from local stock immediately instead of waiting on a long sea leg.
Delivered locally in 48 hoursDisputed batches are put through a rigorous 100% DoD cycle re-test on an authoritative battery test system, protecting the buyer’s commercial rights across the full service life.
SOH ≥ 80% as the lifetime benchmarkNo word games. Every after-sales responsibility, freight-cost owner and replacement standard is written into the contract annex.
| Service and warranty dimension | TIANQIU commercial standard | Typical small exporter / traditional trader |
|---|---|---|
| Warranty period and cycles | 5-year standard commercial warranty / 3,500 cycles (100% DoD) Counted from the dual timestamps of the factory barcode scan and BMS activation | 1-year warranty / 500–800 cycles (out of period means no liability) |
| Capacity fade threshold (SOH) | Free replacement of the whole module below 80% SOH within warranty No depreciation charge, so the buyer absorbs no second-life value loss | Only accepted below 60% SOH, and then repaired by opening the pack rather than replaced |
| Consumables shipped per container | 2% of high-frequency consumables free with every standard container BMS mainboard, relays, fuses and waterproof connectors | No free parts; replacement components must be ordered separately at high cost |
| After-sales logistics and replacement freight | TIANQIU pays the freight to allocate a replacement from the nearest overseas bonded warehouse Dispatched from core transit hubs such as Alexandria and Casablanca | Buyer carries the expensive cross-border Class 9 dangerous-goods return freight |
| Liability assessment and turnaround | Remote 4G IoT plus host logs — no dismantling, no return shipment Liability confirmed within 48 hours and a dispatch order issued in the same step | Mandatory return to the Chinese factory for inspection, taking 3–6 months |
The comparison is drawn on standard commercial three-wheeler and e-moped motive packs. Binding terms are those of the signed commercial motive battery warranty agreement and its annexes.

An agile loop designed for large cross-border orders, cutting the communication overhead and reaching a replacement dispatched from overseas stock in as little as 48 hours.
The buyer exports the fault-instant log file from the BMS host software, and photographs the laser-engraved QR nameplate on the enclosure plus the vehicle wiring as found.
Estimated time: 10 minutesThe RMA request is filed online and routed automatically to the powertrain algorithm panel, which issues a decision report and confirms compensation or replacement within 48 hours.
Committed turnaround: ≤ 48 hoursOnce approved, the system instructs the nearest overseas warehouse (for example Egypt Alexandria or Europe Rotterdam) to dispatch a new module or free original spare parts.
Local dispatch: 24–72 hoursA resident bilingual engineer, or a video session, guides the local technician through PACK installation, CANBUS handshake pairing and a loaded road test, then closes and archives the file.
Guarantee: 100% install-and-runThe clauses below come directly from the commercial motive battery warranty agreement and our overseas hub policy, and each is written into the contract annex.
Counted from the dual timestamps of the factory barcode scan and BMS activation, whichever comes first. Below 80% SOH within warranty, the module is replaced free of charge with no depreciation fee.
The BMS records the 48 hours of charge/discharge current, temperature curve and cell voltage delta before the fault. Engineers read it from the cloud and issue a damage assessment within 24 hours on working days — no dismantling, no return shipment.
Models specified for North Africa and the Middle East use a high-temperature electrolyte formulation and intelligent thermal derating, keeping the same five-year warranty at 55℃. The whole range is IP67 potted with a breathable pressure-relief valve, so sealing and insulation integrity in short deep wading is backed by factory warranty.
If annual failure within one cell batch exceeds the contractual threshold (> 0.3%), a batch compensation clause applies: free additional modules from the factory, credited at double quota against the next container.
Water ingress caused by a physically broken enclosure after extreme impact is not covered by free replacement. The Nairobi warehouse holds standard sheet-metal shells and waterproof seals and will repair at parts-and-labour cost only.
Returning a battery to China as dangerous goods is procedurally heavy and the freight can exceed the value of the goods. Once a hardware fault is confirmed, a brand-new module or complete pack is dispatched from local bonded stock. The customer disposes of the old unit through a locally licensed environmental facility, and the destruction video and certificate offset the value against the next order or travel with the following container.

Once a defect is confirmed by 4G IoT or host logs, TIANQIU carries the replacement freight in full and the buyer never ships the unit back to China.
