Headway 38120s Trolling Motor Battery

Clark from Temptress recently uploaded a video discussing his experiences with building a battery using Headway cells similar to one in this episode. Although he had opened it for demonstration purposes earlier, this particular battery showcases five of the ten-amp-hour Headway cells in a parallel roll configuration. These red stick-like cells pack a punch and can provide significantly more power compared to Prismatic cells.

Differences Between Cell Styles

Available in different styles, the Headway cells offer flexibility for various applications. These cells come in both ten-amp-hour and eight-amp-hour options, providing substantial power output when needed.

Battery Design

In this specific battery configuration, four rows of Headway cells are connected in series, creating a nominal 12V battery. By combining all ten-amp-hour cells in parallel, the battery achieves an impressive total capacity of 50 amp-hours. This arrangement is particularly advantageous for smaller batteries that can benefit from increased power delivery.

Battery Connections and Components

To create the necessary connections, Clark uses copper tubing as the main bus bar for joining. For parallel connections between batteries, he employs hammered flat copper tubing with drilled holes. Additionally, custom-made copper bars connect the cells efficiently.

Balance and Safety Features

An active balance system is incorporated into the battery design to monitor cell voltages and equalize them when necessary. This helps maintain optimal performance and longevity of the cells.

Important Components

A 50-amp BMS (Battery Management System) is used to regulate charging and discharging currents, ensuring the battery’s safe operation. The chosen BMS allows for a 30A charge rate, which aligns with Clark’s usage of this specific battery.

Battery Assembly

To assemble the battery, various components such as wire connectors and circuit breakers are utilized. A large circuit breaker is installed on the negative wire to allow external control of the system’s power.

Design Improvements

In his video, Clark discusses enhancing the battery design by relocating the active balance system for better integration. He also improves cable management and ensures that connections are secure.

Final Assembly

The final assembly involves properly placing the cells, connecting wires, and securing all components in the waterproof casing. Attention is given to wire management, ensuring a tight fit and proper sealing of the battery.
