Does the small busbar indicate the positive or negative terminal
Busbars are designed for a solid connection point from one power supply to multiple branch circuits. Or many branch circuits back to a single power supply. Because switch panels are used as a positive power distribution method, bus bars are typically used on the negative side. A busbar is a solid strip or block made of conductive metal, typically copper and often tin-plated to resist corrosion, designed to distribute electrical power. The positive terminal in a circuit is what creates voltage. hopefully @JohnC or @Guy Stewart (Victron. The problem is that your battery only has a single connection point at the positive and negative terminal post.

DC busbar of the transformer substation
This guide provides a detailed technical description, calculations, design considerations, and best practices for designing busbar systems in substations. As we know it is impractical to connect multiple conductors at one point. Hence we use bus bars, where these connections can be done spaciously and. Here, we provide an overview of common substation busbar configurations—Single Bus, Main and Transfer, Double Breaker/Double Bus, Ring Bus/Ring Main, and Breaker and a Half. Designing a substation involves not only the visible equipment and ratings but also the less apparent factors—operational. Those substations which change the voltage level of electric supply are called transformer substations. These substations receive power at some voltage and deliver it at some other voltage. They are designed in various shapes—rectangular, round, solid, hollow, or flexible—making them versatile enough to meet the needs of diverse applications. In essence, busbars are junction points. A busbar is essentially a metallic strip or bar, typically made of copper or aluminum, that serves as a central point for collecting and distributing electrical current.
