# Advanced Battery Class

The Advanced Battery Class is intended to encourage the use and development of newer battery technologies with greater energy density than traditional lead-acid batteries and to reflect the growing use of these technologies in transportation.

All Standard Class rules apply, with the following exceptions:

1. The combined **rated energy capacity** of all batteries used in the vehicle must not exceed **1.0 kWh**, based on the battery manufacturer's published specifications.
2. The battery manufacturer's published specifications must be available for inspection upon request.
3. The following **sealed production battery types** are permitted, provided the total weight of the batteries does not exceed listed values:
   - **Nickel-Metal Hydride (NiMH)** 41 lbs
   - **Lithium-Ion (Li-ion)** 15 lbs
   - **Lithium Iron Phosphate (LiFePO₄ or LFP)**. 29 lbs
