Cannonfish battery terminal connectors
Bronze top-post terminal connectors with 4 ports, color-coded posts, anti-corrosion washers and a 200A maximum current.
Pros
- 200A maximum current stated
- Bronze construction stated
- Color-coded for positive and negative
- 4 ports for multiple cable connections
Cons
- No warranty term is stated
- Bullets say 4 ports while the spec table says 1-way
- Spec table count figures disagree with the bullets
- WEEE is the only stated mark
Detailed Review
The listing states battery terminal connectors with 4 ports for multiple cable connections per the bullets, color-coded positive and negative, 2 anti-corrosion felt washers, and bronze construction with a 200A maximum current for automotive and marine use. The spec table disagrees with a 1-way circuit, 2 positions and mismatched count figures, so the bullets' pair of connectors and 2 washers is the figure to trust.
Who it's for: anyone who wants a 200A bronze top-post pair with washers. Who should skip it: anyone who needs a stated warranty or matching spec-table figures.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For cable connectors, safety means stated materials and certifications: UL and CSA on the AIRIC heat shrink, RoHS on the AUUTI splice kit, flame-retardant housing on the RVBOATPAT disconnect, and SAE on the Moly Magnolia terminals. None of the five listings states a warranty term.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| AIRIC 1/0 AWG copper cable lugs | 9.7 | 30 | 21 | 21 | 9 | 0 |
| RVBOATPAT 175A quick disconnect connector | 9.5 | 29 | 20 | 20 | 5 | 0 |

| Cannonfish battery terminal connectors | 9.4 | 27 | 19 | 19 | 3 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best battery cable connectors
Match the connector type to the job
These five listings cover three connector types. The AIRIC listing is 1/0 AWG 3/8 in (M10) copper ring lugs: 10 lugs plus 10 3:1 marine-grade adhesive heat shrink tubes, for crimping or soldering onto 1/0 gauge cable. The RVBOATPAT listing is a 175A quick disconnect plug for 4 AWG, 2 AWG and 1/0 AWG cable at up to 600V, with 4 housings, 8 terminals, 2 protective covers and 8 seals in the box. The Moly Magnolia and Cannonfish listings are top-post terminal connectors for SAE/JIS Type A round posts, both with 4 ports for multiple cable connections. The AUUTI listing is a 5-piece 6AWG 80A wire splice kit with screws, heat shrink tubes and a wrench, fitting 6 to 10 wires. For related battery hardware, see our batteries guides.
Compare the stated current and material
Stated current separates the picks. The RVBOATPAT lists 175A with copper silver-plated terminal pins in a solid PC flame-retardant housing. The Cannonfish lists a 200A maximum current with bronze construction. The AUUTI lists 80A with brass splices at 0.98 in long, 0.21 in inside diameter and 0.35 in outside diameter. The AIRIC lists 600V maximum with heavy-duty copper tubular lugs and heat shrink certified by UL and CSA up to 600V and 257F. The Moly Magnolia lists brass and steel with SAE stated. Do not mix the current figures: 175A on the disconnect, 200A on the Cannonfish terminals, 80A on the splice kit.
What the listings leave unclear
Two listings have figures that need care. The Cannonfish bullets state 4 ports for multiple cable connections while its spec table says a 1-way circuit with 2 positions; trust the bullets’ 4 ports. The same spec table gives a unit count of 11 against a number of items of 4, while the bullets and title describe 2 connectors and 2 washers; trust the pair the bullets describe. The Moly Magnolia item dimensions read 3.94 by 0.79 by 11.81 in for a pair of terminal connectors, which does not fit the product and is unclear. The AIRIC listing’s lugs are non-insulated per its spec table; the included heat shrink tubes provide the insulation. For battery disconnect hardware, see our best battery cut off switch picks.
| If you need | Look at |
|---|---|
| Copper lugs for 1/0 cable | AIRIC, 10 lugs, UL stated |
| A quick disconnect plug | RVBOATPAT, 175A, 600V |
| Top-post terminals | Moly Magnolia or Cannonfish, 4 ports |
| A screw-type splice kit | AUUTI, 6AWG, 80A |
| The most certifications stated | AIRIC, UL, CE, ROHS, SGS, ISO9001-2005 |
Sizing Notes
- Match the gauge: 1/0 AWG on the AIRIC lugs, 4 AWG, 2 AWG and 1/0 AWG on the RVBOATPAT, 6AWG on the AUUTI splice kit.
- Match the terminal type: ring lugs, quick disconnect plug, top-post terminals, or splice.
- Compare current on the listings’ own figures: 175A, 200A and 80A across three picks.
- Check the material: copper on the AIRIC, copper silver plating on the RVBOATPAT, brass and bronze on the rest.
- Note the certification marks: UL and CSA on the AIRIC heat shrink, RoHS on the AUUTI, SAE on the Moly Magnolia.
- Trust the bullets over the spec table where they disagree, as with the Cannonfish ports and count.
