Where are the batteries located?

The batteries being located under the cab on frame rails is a design choice that prioritizes weight distribution and accessibility. This placement helps to lower the center of gravity, improving the stability of the fire apparatus during operation. Additionally, having the batteries in this location protects them from direct exposure to the elements, which can prolong their lifespan and maintain performance.

This position also allows for easier access for maintenance and replacement, as crew members can reach the batteries without having to navigate around other truck components. Proper placement of batteries is crucial for efficient electrical operation and can support the overall reliability of the vehicle under a variety of operational conditions.

The other locations mentioned are less ideal for various reasons. For example, batteries under the hood would likely be subjected to extreme heat from the engine, which may shorten their lifespan. A compartment at the rear could complicate access and could potentially lead to balance issues. Mounting on the truck's roof would raise the center of gravity, posing a risk during maneuvers and could lead to stability issues.
