PACK WIRING
Battery-pack connections
Specify the conductor size, DC circuit requirements and connection length for the pack drawing.
Typical application
APPLICATION / Battery & energy storage
Silicone Cable for
Battery & Energy Storage Equipment
Battery-pack connections and BMS sampling leads.
The single-core wire shown uses fine-stranded tinned copper and silicone insulation, in listed sizes from 28 AWG to 2 AWG. Its fixed-installation rating is −60 °C (−76°F) to +180 °C (356°F) continuous and +200 °C (392°F) short-term.
AT A GLANCE
Battery pack wiring at a glance
Each battery-pack connection and the silicone wire we start from.
| Connection | Cable construction | Key point |
|---|---|---|
| Battery-pack connections | Flexible silicone single-core wire, 28 AWG to 2 AWG | −60 °C (−76°F) to +180 °C (356°F) continuous, +200 °C (392°F) short-term |
| BMS sampling wires | Flexible silicone single-core wire in colour options | Colour options to identify each sampling lead |
| Cabinet, inverter and grid links | Separate cable specification | Not covered by this wire |
CONNECTION TASKS
Battery equipment wiring
The two pack connections below are typical uses of this wire. Cabinet, inverter and grid-side cabling of a storage system need their own cable specification.
SENSING
BMS sampling wires
Show the sampling points, wire identification and connector specification. Keep these requirements separate from the power conductors.
Typical application
SYSTEM BOUNDARY
Cabinet and inverter interfaces
Identify where the proposed wire ends. Outdoor runs, inverter links and grid connections need their own cable specifications.
Separate cable specification
SELECTION CHECKS
Operating conditions to specify
Include these conditions with your enquiry so we can select the right cable.
Electrical circuit
Working voltage, current and circuit function decide the wire size and the wire standard for each connection.
Pack routing
Available space, wire length, bend locations and assembly temperature decide how the wire can be routed.
Terminations & scope
Terminals, connectors and whether you need wire only define the scope. Assembly supply and testing are agreed separately.

APPLICATION LIMITS
Battery pack wiring vs. system cabling
Battery-pack leads, BMS sampling wires and site cables have different circuit functions.
- Power lead
- Conductor size, insulation diameter, connection length and terminal drawing.
- Sampling lead
- Sampling circuit, wire colour, identification and connector pin assignment.
- Site cable
- Submit a separate specification for external AC, communication or grid-side cabling.

BEFORE YOU SPECIFY
Frequently asked questions
Does this cover a complete BESS installation?
No. This page covers wiring inside battery packs, including BMS sampling. Medium-voltage, direct-burial and site cabling need their own cable specification.
Which UL style and voltage rating apply?
The extra-flexible construction shown is rated 600 V. The factory datasheet lists UL 3132, UL 3135 and UL 3239 as separate style references with different voltage ratings; it does not provide model-specific UL certificates.
Which wire sizes are available for battery-pack wiring?
We list 28 AWG to 2 AWG fine-stranded silicone wire, with outside diameters from 1.2 mm to 12.5 mm. Other sizes are made to order.
