Energy storage

Battery interconnects and power leads, built for real current.

Battery packs and BESS modules need power leads that carry current and sense harnesses that read every cell correctly. We build both — lugs crimped and pull-tested, insulation to your voltage class, and hi-pot on every lot where specified.

Cell sense harness with keyed connector, power leads lugged
Typical assemblies

What battery and BESS teams send us

01

Cell and module sense harnesses

Voltage-sense and NTC temperature leads, keyed connectors, mapping verified 100%.

02

High-current power leads

Lugged and heat-shrunk, up to AWG 8 standard; heavier gauges quoted on request.

03

BMS communication cables

CAN and shielded twisted-pair links between modules and controller.

04

Fuse and contactor leads

Ring-terminated, color-coded, torque-ready.

05

Charger and inverter pigtails

SB-class and customer-specified high-current connectors.

06

Enclosure harnesses

Fan, indicator and interlock wiring for pack enclosures.

What matters here

What gets checked before the PO

Energy storage buyers check current rating, voltage class and sense mapping. Each has a documented answer.

Current and gaugeUp to AWG 8 standard; heavier gauges quoted on request; lugs crimped with pull-force verified
Voltage classInsulation rated to your system voltage; hi-pot per plan
Sense mappingPin-to-cell mapping verified 100% before shipment
ThermalHigh-temperature jackets (XLPE, silicone) as specified
ComplianceUL-listed wire; RoHS/REACH parts
Safety labelingPolarity and voltage labels per drawing
