Not recommended for most EV conversions. * Nickel-Metal Hydride (NiMH) Batteries: Offer better performance than lead-acid batteries, but still relatively heavy and have a limited lifespan. * Lithium-Ion Batteries: The most popular choice for EV conversions due to their high energy density, long lifespan, and relatively light weight. Different Lithium-Ion chemistries exist, each with its own pros and cons (e.g., Lithium Iron Phosphate (LiFePO4), Lithium Nickel Manganese Cobalt Oxide (NMC)).

Lithium-ion batteries are generally the best choice for most EV conversions, but they are also the most expensive. Carefully consider your budget and desired range when selecting a battery pack.

Battery Capacity and Voltage

Battery capacity (measured in kilowatt-hours or kWh) determines the range of your vehicle. Higher capacity batteries provide longer range, but are also more expensive and heavier.

Battery voltage is another important factor to consider. The voltage of your battery pack must match the voltage requirements of your motor and motor controller. Using the wrong voltage can damage your components.

A common configuration is a high-voltage system (e.g., 400V or 800V) for better efficiency and faster charging, but these systems are more complex and require specialized components.

Battery Management System (BMS)

A BMS is essential for protecting your battery pack. It monitors the voltage, temperature, and current of each cell in the battery pack and prevents overcharging, over-discharging, and overheating. A good BMS will significantly extend the lifespan of your battery pack.

Ensure that your EV conversion kit includes a high-quality BMS that is compatible with your chosen battery chemistry.
