Tropical stress validation and chassis fit matrix

Designed for the flooded monsoon roads of Ho Chi Minh City and Hanoi, for sustained high humidity, and for riders running 20-hour days.

IP67 dual seal + breatherCAN 2.0B / 4G IoT7.8–14.5kg one-handed100% RETROFIT FIT
  • Flood and wading protection: for the routine monsoon flooding of Ho Chi Minh City, a dual IP67 seal ring with a breather valve holds insulation resistance above 500MΩ and wades 400mm without tripping, keeping riders working through the worst weather.
  • High-speed swap handshake: onboard CAN 2.0B and 4G IoT modules complete the swap-cabinet handshake in 0.8 seconds and synchronise SOC and SOH data, preventing arcing at the swap connector and matching the mainstream Vietnamese swap networks.
  • One-hand portability with low heat rise: a reinforced aviation-aluminium folding handle balances 7.8–14.5kg for one-handed carrying, while thermally conductive potting holds the working temperature rise below 4℃ at 40℃ ground heat.
  • Loss-free fit to standard bays: moulded dimensions match the VinFast Feliz and Klara, Yadea models and Honda Wave conversion bays exactly, locking in without modification and sharply cutting a fleet's conversion cost.

Vietnam QCVN approval and the Form E zero-tariff route

  1. 01fact_check

    QCVN 91:2019 standard approval

    The packs pass the Vietnamese Ministry of Transport (BGTVT) national technical regulation testing in full, covering nail penetration, crush, overcharge, short circuit and high and low temperature charge and discharge, enabling direct import approval.

    CNAS / CMA laboratory reports supplied with the order · support for VR national vehicle quality inspection centre registration
  2. 02description

    China–ASEAN Form E certificate of origin

    The official Form E certificate of origin is issued by the Chinese entry-exit inspection and quarantine authority or customs, cutting the customs duty straight to 0% and relieving Vietnamese importers of working-capital pressure at clearance.

    Duty 15% → 0%
  3. 03sailing

    Shekou / Nansha direct to Ho Chi Minh City and Hai Phong

    Direct Pearl River Delta sailings are fast: Hai Phong takes only 3 days and Cat Lai in Ho Chi Minh City 4–5 days, with legitimate Class 9 dangerous-goods container booking and no demurrage risk.

helpVietnam Fleet FAQ

Vietnam fleet procurement and import clearance FAQs

Does an import into Vietnam need QCVN 91 approval, and can TIANQIU supply the test reports?expand_more
Yes. Under Vietnamese Ministry of Transport (BGTVT) rules, batteries for commercially operated electric two-wheelers must hold QCVN 91:2019 approval. Battery-side test reports ship with the order and help Vietnamese importers complete registration with the VR national vehicle quality inspection centre.
How does the pack handle the 400mm road flooding that Ho Chi Minh City sees in every heavy rain?expand_more
The pack uses automotive-grade double fluororubber seal rings to IP67. A watertight pressure-relief breather with an ePTFE membrane sits on the lid, equalising internal pressure under water while completely blocking liquid ingress. Every unit passes a 100% vacuum leak test at the factory, so even 30 minutes of continuous immersion keeps insulation resistance above 500MΩ and neither controller nor motor trips out.
With delivery fleets charging or swapping two to three times a day, how is cell life and fade controlled?expand_more
We select automotive A-grade prismatic aluminium-case LiFePO4 cells with a 1C charge and discharge cycle life above 3,500 cycles at ≥80% capacity retention. Even a high-frequency rider covering 200km a day with two to three swaps can serve a stable 3–4 years under Vietnamese high-temperature conditions, greatly extending a fleet's depreciation period.
How is the swap communication protocol (CANbus / 4G IoT) integrated with local Vietnamese cabinet platforms?expand_more
The TIANQIU BMS ships with standard CAN 2.0B and RS485 interfaces plus a complete swap-handshake register dictionary. Before dispatch we can write in customer-specific handshake keys and plug-in discharge delays for local cabinet controllers such as Selex, Dat Bike and the VinFast ecosystem, and our Tan Binh engineering team in Ho Chi Minh City can support cabinet-side commissioning on site.
How long does sea freight from China to Vietnam take, and how is a container packed for Class 9 dangerous goods?expand_more
We ship year-round from Shenzhen Shekou or Guangzhou Nansha direct to Cat Lai in Ho Chi Minh City (about 4 days) or Hai Phong (about 3 days). Packing uses UN-certified heavy-duty dangerous-goods cartons with fire-retardant anti-static EPE cushioning, fumigated pallets secured against tipping, fully compliant with UN3480 and accompanied by the latest sea-transport identification report and packing certificate.
How is the Form E certificate of origin used, and does it remove duty entirely at destination?expand_more
Under the China–ASEAN Free Trade Area preferential trade agreement lithium batteries sit on the Form E reduction list. After loading, our customs team issues the electronic and original Form E immediately. Once the Vietnamese broker enters the certificate number the duty drops from the standard 15% to 0%, leaving only local VAT, which materially improves margin.
