Aluminium Bus Bar 25X25X2 L Type

The Aluminium Bus Bar 25X25X2 L Type is an aluminium battery busbar/interconnect formed in an L-type profile with a supplied 25 × 25 × 2 mm size reference. It is intended for compact battery-pack, terminal and DC power-distribution layouts where a rigid conductive link is preferred over a flexible cable. Buyer searches may include aluminium battery bus bar, 25x25x2 busbar, L type battery connector, battery terminal link and lithium battery aluminium interconnect.

A busbar provides a low-profile current path between compatible terminals, cells or power-distribution points. The L-shaped geometry can help change direction or bridge two surfaces in a compact assembly, but the exact hole pattern, bend geometry and mounting arrangement must match the physical equipment. The dimensions in the product name should be treated as the supplied part-size reference; current capability cannot be determined from those dimensions alone without considering alloy, effective cross-section, length, joint resistance and thermal environment.

In high-current DC systems, connection resistance is often concentrated at bolted joints rather than in the middle of the bar. Flat mating surfaces, correct fastener size, clean contact areas and controlled tightening torque all influence heat generation and long-term stability. Aluminium also requires attention to surface condition and compatible joint design because oxide layers and dissimilar-metal interfaces can increase resistance or corrosion risk if the connection is not engineered correctly.

Busbar sizing should be based on continuous current, allowable temperature rise, duty cycle, ambient temperature and fault-current protection. The bar should not be used as an unfused substitute for a properly engineered distribution system. If copper lugs, plated terminals or steel hardware are connected to aluminium, the builder should use an appropriate interface method and inspect the joint periodically where the application demands it.

Choose this L-type aluminium busbar by matching the physical 25 × 25 × 2 mm form factor, hole or stud arrangement, bend orientation, terminal spacing and current-path requirement. For replacement work, compare the original part directly because a similar external size may still have a different hole pitch or bend position. Also confirm enclosure clearance so the bar cannot contact adjacent terminals or conductive panels.

Applications

• Lithium battery pack terminal and busbar interconnection.

• ESS, inverter and UPS battery cabinet DC distribution.

• Prismatic-cell and module-level battery assembly when the geometry matches.

• Industrial DC panels, prototype battery systems and test fixtures.

• Battery repair and replacement work requiring an L-type aluminium interconnect.

Installation Guide

De-energize the battery before fitting the busbar. Keep the work area free from loose metal and cover adjacent live terminals to prevent accidental short circuits. Clean mating surfaces, align the bar without forcing it into position and use the correct fasteners and washers for the terminal design. Tighten using the equipment manufacturer's torque specification where available. After commissioning, inspect the joint for abnormal heating, discoloration or loosening during initial load cycles.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components. The catalog brings together BMS boards, connectors, insulation materials, battery wiring, terminals, fuses, enclosures, testing equipment and assembly tools. For battery builders, repair workshops and OEM buyers, sourcing related components from one specialist catalog can make specification matching and procurement easier. Final suitability should still be checked against the exact battery design, equipment model and electrical requirements before installation.
