Electric three-wheelers — e-rickshaws, tuk-tuks, Bajaj-class passenger carriers — are converting from lead-acid to lithium across India, Bangladesh, Southeast Asia, and Africa. The buyer is not a hobbyist: it’s a fleet operator running dozens or hundreds of vehicles where range per charge, battery-swap downtime, and GPS fleet management decide profitability. This page covers 48V/60V pack selection, the lead-acid conversion math, fleet telematics requirements, and wholesale/OEM sourcing.
Voltage Map: 48V vs 60V
| System | Typical pack | Use case |
|---|---|---|
| 48V | 48V 80–200Ah (16S) | Standard passenger e-rickshaws, lighter loads, flat terrain |
| 60V | 60V 100–150Ah (19S) | Heavier loads, hilly routes, higher-speed variants |
48V is the volume standard with the deepest charger and controller ecosystem. 60V serves performance and heavy-duty niches — pack structure and interfaces are confirmed per project, not stocked as standard SKUs.
Range Per Charge: the Fleet Operator’s Formula
Range ≈ pack kWh × drivetrain efficiency ÷ consumption per km — and consumption depends on passenger load, terrain, and driving pattern more than on the battery brand. A 48V 100Ah pack (5.12kWh) typically delivers a full operating shift for a standard passenger rickshaw; operators size up to 150–200Ah for extended routes or heavier loads.
What operators actually buy on: kilometers per charge in their duty cycle, verified by trial — not the laboratory range figure. Pilot a small batch on the actual route before committing the fleet.
Lead-Acid to Lithium: the Conversion Math
- Weight: a 48V lead-acid set weighs 120–150kg; the lithium equivalent is 40–50kg. Less weight means more range per charge and lower energy consumption — the conversion partially pays for itself in electricity.
- Charging time: lead-acid needs 8–10 hours; lithium charges in 3–5 hours. Faster turnaround means fewer spare batteries per vehicle.
- Cycle life: 300–500 cycles (lead-acid) vs 2,000+ (LiFePO4) — the lithium pack outlasts multiple lead-acid sets, which is where fleet TCO turns positive.
- Maintenance: no watering, no equalization — critical where drivers, not technicians, handle daily charging.
Fleet Telematics: GPS and Battery Data
Fleet operators increasingly require GPS tracking and battery telemetry as standard: location, state of charge, and cycle counts reported to a fleet dashboard. Packs built for fleet channels include telematics-ready BMS with data output — specify the communication interface (CAN/RS485/GPRS) and the fleet platform at quotation. This is a hard requirement for financed and leased fleets, not an option.
Battery Swapping for Fleets
Where charging downtime costs revenue — delivery fleets, high-utilization passenger routes — operators are moving to battery swapping: standardized packs exchanged at swap stations in minutes instead of hours of charging.
- Standardization is the prerequisite: pack dimensions, electrical interface, and communication protocol must match the swap station. There is no universal standard — compatibility is confirmed per operator and per station design.
- BMS data and billing: swap networks bill by energy or by swap; the BMS must report accurate state of charge and cycle data to the operator’s platform.
- Second life: retired swap packs enter refurbishment and second-life applications — operators factor residual value into TCO.
- LJY’s role: pack design and manufacturing coordination to the operator’s swap-station specification — dimensions, interface, protocol, and telemetry confirmed per project. No compatibility with any specific swap network is claimed or implied.
Wholesale and OEM/ODM
LJY Energy supplies 48V e-rickshaw LiFePO4 packs wholesale to fleet operators, vehicle assemblers, and distributors — with telematics-ready BMS options and fleet packaging. 60V configurations and swap-station-compatible packs are coordinated per project.
What a fleet quotation confirms: system voltage (48V/60V); capacity per duty cycle; telematics/BMS data requirements; charger specification; vehicle model and battery compartment dimensions; MOQ, lead time, and fleet pricing tiers.

Frequently Asked Questions
48V or 60V for my e-rickshaw fleet?
48V for standard passenger duty — deepest parts ecosystem, lowest cost. 60V for heavy loads or hilly routes — confirmed per project.
How do I verify range before ordering in bulk?
Pilot a small batch on your actual route with your actual passenger load. Laboratory range figures don’t predict rickshaw duty cycles.
Can the BMS integrate with our fleet management platform?
Telematics-ready BMS with CAN/RS485/GPRS output is available — specify your platform’s data interface at quotation and we confirm compatibility per project.
Do you support battery swapping pack designs?
Yes, as OEM/ODM coordination to your swap station’s mechanical, electrical, and protocol specification. No compatibility with any specific network is implied.
