An automotive YouTuber has successfully converted a classic early 2000s Reva G-Wiz electric microcar into a vehicle powered entirely by 500 repurposed vape batteries. The unconventional build, which has been fully tested on public roads, delivers a practical 18-mile range and a top speed of 35 miles per hour, with the added modern convenience of a USB-C charging port. This project demonstrates a radical and accessible approach to electric vehicle power, bypassing traditional, expensive lithium-ion battery packs in favor of widely available consumer electronics components.
The Vape Battery Car Build: Specifications and Performance
The core of this automotive experiment lies in its power source: 500 individual 18650 lithium-ion cells, identical to those commonly found in disposable and rechargeable vape devices. These cells were arranged into custom battery packs, wired in series and parallel configurations to meet the voltage and current demands of the Reva G-Wiz’s original electric motor. The total battery capacity is estimated to be around 7.4 kWh, a figure comparable to smaller modern electric bicycles but sufficient for the lightweight microcar.
Real-World Driving Metrics
During on-road testing, the vehicle achieved a consistent range of approximately 18 miles on a single charge under mixed urban driving conditions. Its top speed was electronically limited to 35 mph, making it suitable for city commuting and low-speed zones. The car retains the original G-Wiz’s diminutive dimensions and lightweight construction, which proved crucial in making the vape battery pack a viable power unit. Acceleration is described as modest but adequate for its intended use case.
The USB-C Charging Innovation
Perhaps the most surprising feature is the integration of a USB-C charging port. This is not a gimmick; it is a functional part of the charging system. The builder implemented a power delivery system that allows the car’s large battery bank to be slowly charged via this standardized port, alongside a conventional higher-amperage charger. This highlights the project’s ethos of utilizing ubiquitous, off-the-shelf technology.
Deconstructing the Reva G-Wiz Platform
The choice of vehicle was strategic. The Reva G-Wiz, produced between 2001 and 2012, was one of the first mass-produced electric city cars. It was originally powered by lead-acid or later, nickel-metal hydride batteries, offering limited range and performance. Its simple, lightweight chassis and unsophisticated drivetrain make it an ideal candidate for such an unconventional retrofit. The YouTuber essentially replaced one outdated battery technology with a novel, modular one based on contemporary cells.
Inherent Advantages of the Donor Vehicle
The G-Wiz’s extremely low kerb weight—under 900 pounds—meant the power requirements were minimal compared to a standard car. Its compact size provided just enough space to package the 500 batteries securely. Furthermore, its original electrical architecture was simple enough to interface with the new battery management system (BMS) required to monitor the vast array of individual cells, a critical safety component in any lithium-ion battery pack.
Technical Challenges and Safety Considerations
Powering a car with vape batteries is not as simple as taping them together. The primary technical hurdle was building a robust Battery Management System capable of monitoring the voltage, temperature, and health of all 500 cells to prevent overcharging, over-discharging, and thermal runaway—a potential fire risk. The builder had to design custom circuitry and harnesses to manage this complexity.
The Critical Role of the BMS
A failure in a single cell could be catastrophic in such a large pack. The implemented BMS continuously balances the charge across all cells and will shut down the pack if it detects dangerous parameters. This system is more complex than those found in commercial EVs due to the pack’s modular, non-monolithic nature. Ventilation and physical protection for the batteries were also major design foci to ensure safe operation.
Longevity and Practicality Concerns
While the project proves concept viability, questions remain about long-term durability. Vape batteries are not engineered for the deep discharge cycles and high cumulative energy throughput of an automotive application. Their lifespan in this demanding role is untested. Furthermore, the charging time via USB-C would be impractically long for daily use, necessitating the secondary charging system.
Broader Implications for EV Hobbyists and Innovation
This build is more than a quirky internet video; it represents a democratization of EV technology. It proves that with technical skill, the fundamental components of an electric vehicle can be sourced from the consumer electronics aisle, potentially lowering the barrier to entry for custom EV projects. It sparks a conversation about modular, repairable, and sustainable battery solutions.
A Blueprint for DIY Electric Mobility
For the hobbyist community, the project serves as a detailed case study in battery pack construction and integration. It demonstrates that functional, short-range urban EVs can be created without access to proprietary automotive-grade battery packs. This could inspire conversions of other lightweight vehicles, such as classic mini cars or even custom-built trikes and quadricycles.
Environmental and Economic Angles
On one hand, the project promotes the reuse of thousands of individual cells that might otherwise be discarded, aligning with circular economy principles. On the other, it raises questions about the lifecycle and sourcing of these mass-produced lithium-ion cells. Economically, it highlights the significant cost disparity between a bespoke automotive battery and aggregated consumer cells, though the latter involves immense labor.
The Future of Modular and Alternative Battery Tech
While no one expects major manufacturers to adopt vape batteries, this experiment underscores a growing interest in alternative and modular energy storage. Concepts like swappable battery packs, standardized cell formats, and more repairable battery designs are gaining traction. This build takes those ideas to an extreme, literal endpoint.
Potential for Niche Applications
The technology demonstrated here could find use in low-speed neighborhood vehicles, industrial campus transports, or in regions where access to traditional EV parts is limited but consumer electronics are plentiful. It represents a form of appropriate technology—using what is widely available to solve a local mobility need.
Catalyst for Discussion on Battery Design
Ultimately, the vape battery car forces a re-examination of what a car battery must be. It challenges the assumption that only large, sealed, monolithic packs are valid. In an era striving for sustainability and repairability, the concept of a serviceable, module-by-module battery system, even if not made from vape parts, holds significant appeal for a segment of users and innovators.
The sight of a quirky, twenty-year-old electric car humming down a road powered by the same batteries found in a convenience store is a powerful symbol of technological convergence. It blurs the lines between consumer electronics and automotive engineering, suggesting that the future of personal electric transport might be more adaptable and accessible than previously imagined. This project proves that innovation often comes from lateral thinking and applying mass-produced technology in entirely new contexts, pushing the boundaries of what is considered possible in a home garage.
