Powering the Next Generation of Classic Land Rovers
The electric vehicle industry has undergone a dramatic transformation over the last decade, and 2026 marks a pivotal turning point for classic electrification. With EVs making up over 20% of new car registrations and solid-state technology on the horizon, more owners are turning to electrification to preserve and enhance the value of their classic Land Rovers.
At Electric Car Converts, we specialise in converting Land Rover Defenders, Series models and Range Rover Classics to electric using the same advanced battery technology that powers the world’s most efficient EVs whether you’re commissioning a full conversion or fitting one of our Land Rover EV conversion kits, understanding how battery systems work helps you make informed decisions about performance, reliability and long-term value.
What Kind of Batteries Power Electric Land Rovers?
The heart of every electric Land Rover conversion is its lithium-ion battery system — the same chemistry used in Teslas, adapted to fit the structure of a classic 4×4.
Our conversions exclusively use Tesla and Fellten components due to their proven reliability, high energy density and long life cycles. These systems provide the best balance of range, weight distribution and safety for vintage Land Rover platforms.
Older technologies such as lead-acid and nickel-metal hydride batteries are no longer viable options for performance conversions. They’re heavier, less efficient and degrade faster. Lithium-ion remains the gold standard, offering the power, range and safety required for serious electric restoration work.
Inside an Electric Land Rover Battery Pack
Each electric Land Rover battery pack is built from a series of interconnected modules, typically between 55kWh and 110kWh depending on range and model.
Key components include:
- Cathode and anode: Store and release electrical energy
- Electrolyte: Allows lithium ions to move efficiently
- Separator: Prevents short circuits
- Battery Management System (BMS): Monitors and balances temperature, voltage and charge
Our engineers design every system to fit seamlessly into the Land Rover chassis without cutting or welding. This maintains full reversibility — a key factor for preserving collector value.
Battery Capacity and Range
Battery capacity determines how far your electric Land Rover will travel on a single charge.
| System | Range (miles) | Battery Capacity | Motor Type |
|---|---|---|---|
| Standard Range Kit | ~150 | 55 kWh | Tesla Model 3 Motor |
| Long Range Kit | ~300 | 110 kWh | Tesla Model S Rear Drive Unit |
Every system is fully tested on our in-house chassis before installation or shipping. Even as a kit, each package arrives as a complete, plug-and-play setup — no welding, wiring or guesswork required.
Battery Management and Longevity
A properly managed lithium-ion system should last 15–20 years or more. All Electric Car Converts systems include a dedicated Battery Management System that continuously monitors temperature, voltage and state of charge. It prevents overcharging and ensures consistent performance, extending overall lifespan.
Each pack includes an integrated cooling loop that maintains optimal battery temperature in all conditions. Our designs have been proven in the field, from British winters to California heat.
Charging Your Electric Land Rover
Every ECC-built Land Rover and EV kit supports all modern charging options:
- 7kW AC home charging (approx. 4–8 hours)
- 3-pin home charging for convenience
- 70kW DC rapid charging (20–80% in around 30 minutes)
The UK and EU now have over 60,000 public charge points, with rapid chargers available roughly every 20 miles. This infrastructure growth makes electric Land Rover ownership more practical than ever.
What Affects Battery Life in Classic Conversions?
Battery degradation is gradual and largely depends on how the system is used. Our builds are engineered to reduce wear by balancing current draw, optimising temperature control and preventing deep discharges.
Simple habits also help: avoid charging to 100% every time, drive steadily and limit unnecessary rapid charges. Unlike petrol or diesel engines, electric drivetrains don’t suffer from idle wear or oil-related breakdowns, making them far more consistent over time.
Innovation and the Future
The next leap for EVs is solid-state battery technology, which promises lighter packs, faster charging and increased safety. Our engineering team at Electric Car Converts constantly monitors advancements in the field, ensuring that our systems can evolve with emerging technology.
Because our conversion kits are modular, existing owners will be able to retrofit future upgrades — including solid-state systems — without replacing the entire installation.
The Electric Car Converts Advantage
Every system we produce is designed and tested in the UK, built for safety, reliability and performance. We use genuine Tesla and Fellten systems, avoid cutting or welding the chassis and ensure every build remains fully reversible.
Our conversions offer instant torque, smoother performance and drastically reduced maintenance costs — all while maintaining the vehicle’s classic appearance and long-term value.
Future-Proof Your Land Rover
Whether you want a full in-house conversion or a ready-to-install kit shipped worldwide, we’ll help you protect your Land Rover’s legacy while adapting it for the electric future.
