Engineered for the steep gradients of the Great Rift Valley, equatorial 45℃ ground heat and punishing red-dirt corrugation. It is also built for the local operating ecosystem: native Safaricom M-Pesa wallet settlement and a PAYGO 4G-IoT soft-limiting loop for arrears. Automotive-grade LFP delivers eight years of service life and releases real margin for fleets in Nairobi and on the coast.

From Bajaj tuk-tuk conversions on busy Nairobi streets to the tropical, salt-laden Indian Ocean climate of Mombasa, TIANQIU covers everything from firmware to local workshop enablement.
Because Kenyan operating conditions swing so widely between cities, TIANQIU refuses a one-size-fits-all catalogue product and instead offers localised firmware and reinforced hardware options to volume customers.
Average altitude 1,795m with a day-night spread above 18°C. Long peak-hour congestion means frequent regenerative braking, which drives localised cell heating.
Thermal phase-change silicone pads: voltage drop held within 15mV, eliminating local hot spots.
Bi-directional regen protection: prevents overvoltage on recharge and extends life to 3,500 cycles.
Year-round 30–36°C with heavy sea vapour and highly corrosive salt spray; conventional terminals oxidise, short and lose insulation.
Nano three-proof encapsulation: full passivation of the PCB and main copper busbars, salt spray >1000h.
BMS 55°C derating protection: prevents summer afternoon thermal trips and keeps operations continuous.
Around Lake Victoria and the inland agricultural belt, unpaved red-dirt washboard roads shake cells hard enough to break internal tabs and fatigue the enclosure.
Aerospace ribbed frame: 50G three-axis mechanical shock validated, with laser full-penetration copper-aluminium busbars.
Flame-retardant structural potting: zero module movement, insulation resistance >500MΩ.
| Target vehicle and chassis | Recommended standard system | Loaded range (km) | Dimensions and enclosure material | BMS communication protocol | Container loading (20GP) |
|---|---|---|---|---|---|
| Bajaj RE 205cc Tuk Tuk Number one passenger platform in India and East Africa | 60V 120Ah (7.2 kWh) Automotive LFP prismatic aluminium cells | 125 – 140 km (4 passengers) | 460 × 320 × 280 mm 2.0mm cold-rolled steel armour + anti-theft pin | CAN 2.0B / RS485 | 144 units / 20GP |
| TVS King Kargo / Deluxe Heavy-duty combined passenger and cargo platform | 60V 100Ah (6.0 kWh) Integrated 12V DC-DC step-down | 105 – 120 km (350kg payload) | 430 × 310 × 260 mm Fast latch into the original fuel-tank bay | CAN 2.0B / 4G-IoT | 168 units / 20GP |
| Boda Boda two-wheeler (Boxer 150 replacement) East Africa’s most active urban delivery and passenger fleet | 72V 45Ah × 2 parallel packs (6.48 kWh) Hand-carry swap, twin-rail centre mount | 140 – 150 km (standard load) | 185 × 165 × 390 mm (×2) IP67 lightweight drop-resistant aluminium | UART / BLE 5.0 / NFC | 320 sets (640 packs) / 20GP |
| Heavy agricultural / light logistics tricycle (Cargo Loader) Rift Valley and peri-urban produce haulage | 60V 150Ah / 72V 100Ah 3.0mm ultra-thick puncture-proof base plate | 70 – 85 km (800kg full load) | 520 × 340 × 290 mm Load-bed centre mount with heavy reinforcement | CANopen / RS485 | 120 units / 20GP |
Passenger and cargo tricycles map to the passenger three-wheeler pack and the heavy-duty cargo tricycle pack; the Boda Boda twin-pack platform maps to the two-wheeler swap pack. Container quantities are calculated against IMO UN packing weight limits and confirmed in the final loading plan.

In Kenya, 93% of adults use the M-Pesa mobile wallet. The hardest problems in asset finance have always been collecting arrears, and the rear-end collisions caused by remote shutdown at speed. The TIANQIU BMS two-stage soft-limiting logic balances collection rates against rider safety.
The rider enters the operator Paybill account and tops up discharge time by the day or by the week.
USSD *334# / AppThe operator server completes a millisecond handshake with the TIANQIU IoT API, and the 4G module updates the pack discharge countdown.
Webhook callback (< 400ms)Past the rental due date the main relay is not opened. Instead the rated current is limited to 20%, guaranteeing a safe low-speed ride back to a payment point.
20% current limit · main relay stays closedIf the antenna is forcibly removed or the enclosure is opened abnormally, the BMS locks and a coin-cell backup keeps reporting position.
GPS geofence + offline RTC
The operator server, the TIANQIU telematics cloud and the in-vehicle BMS communicate over MQTT / TLS 1.3 with end-to-end encryption, so every step from wallet payment to discharge quota update is auditable.
As an established manufacturer exporting lithium batteries (UN 3480, Class 9 dangerous goods) by sea, TIANQIU holds its own booking code and a complete customs document system — so overseas buyers never face a held container or a demurrage penalty.
We issue the China Customs packing certificate for dangerous goods, the UN38.3 vibration and drop test report and the 16-point bilingual MSDS, and complete Class 9 hazard labelling.
Class 9 labelling · 100% compliantWorking to Kenya Bureau of Standards requirements, we inspect with SGS / CCIC and issue the export CoC certificate, securing the no-unstuffing fast clearance channel at Mombasa.
One CoC per shipment · no customs re-inspectionLong-term dangerous-goods direct services with CMA CGM and Maersk. Inside the container, heavy-duty shock-isolating wooden pallets are double-braced to prevent damage in heavy seas.
Transit 18–22 days · full marine all-risks coverContainers move from the port onto the SGR standard-gauge railway without transhipment, reaching the Nairobi ICD in 8 hours and radiating onward to Uganda, Rwanda and the wider East African Community market.
Nairobi transfer < 24h · bonded warehouse collectionTell us your fleet conversion requirement or trade agency plan. Within four working hours the TIANQIU East Africa engineering division will send the full KEBS / PVoC document checklist, 20GP and 40HQ loading details into Nairobi / Mombasa with live ocean freight, and eligibility to apply for an M-Pesa PAYGO 4G module firmware test unit.
