Modular Heavy-Duty Battery Terminal
About this item
- Innovative Split Design Battery Terminal: Comes with an interchangeable head of fixed size (M8) for M8 lead-acid battery posts. Other head sizes (M4, M5, M6, M10, 1/4-20, 5/16-18, 3/8-16) available as optional accessories for easy customization.
- Wide Battery Compatibility: Optimally designed for Lead Acid Batteries including AGM, GEL, WET, MF, and CA/CA types. Fits various battery post types including Side Post, Bolt Down, and Screw Down.
- Conductive Zone for Performance: Crafted from heat-treated 6061-T6 aluminum alloy with precision CNC machining. The connection area has the anodic layer removed to form a conductive zone, ensuring seamless conductivity. Color anodization adds outstanding corrosion resistance.
- Multi-Cable Compatibility: 6-hole, 12-way design snugly accommodates 00 (2/0) AWG welding cables and works with 1/0, 2, 4, 6, and 8 AWG. Total capacity of up to 12 cables for car and car-audio battery needs.
- Broad Applications: Designed for a wide variety of vehicles - cars, pickups, motorcycles, caravans, RVs, buses, and trucks.

Fitment & clearance
The terminal body measures 3.7 x 1.8 x 0.8 in (length x width x height). It weighs 15.4 oz. That is the size of the part itself. How tall the assembly ends up sitting above your battery depends on how far your post stands proud of the case, which varies between batteries — so measure your vertical gap and your post height, then compare.

Independently tested, not just claimed
Anyone can print "aircraft-grade aluminium" on a listing. We had ours tested by SGS, an independent laboratory, and we publish the report numbers so you can ask for them.
| Series | SGS report | Date | Result |
|---|---|---|---|
| STING | KK-25-09211A | 13 Sep 2025 | A6061-T6 composition verified · 46.0% IACS |
| Eagle | KK-26-04498 | 05 Jun 2026 | 48.0% IACS |
| FLEX | KK-26-04499 | 05 Jun 2026 | 46.7% IACS |
Electrical conductivity tested to ASTM E1004-23; IACS is the standard scale for how well a metal conducts. The aluminium is separately tensile tested to ASTM B557-15 — 52 ksi tensile, 50 ksi yield, against 6061-T6 specification minimums of 38 and 35. Machined and tested in Taiwan.

Coming: Battery Terminal Fitment & Torque Guide
Post identification chart, the four measurements to take in your own engine bay, torque table, and a print-to-scale paper template you can hold against your battery before you order. Body dimensions are already published in the dimension table.
We are still measuring — every dimension in the guide is taken off the actual product rather than a drawing, and we would rather publish it late than publish a number we have not verified. There is no signup form here yet because we have nothing to send you yet. When the guide is ready this box becomes the place to get it.
