- High Quality: 4 AWG battery cables are made of pure copper and tinned copper lugs with superior corrosion and oxidation resistance, which improves the oxidation resistance of copper and maintains its conductivity better.
- Package includes – as a set 2 pcs 4AWG battery power cable (positive (red) and negative (black) copper battery cables) , 12 inch/1 feet for every battery cables, fit 3/8 ” tinned copper ring terminals.
- Safe & Durable – Battery cables with terminals feature tinned copper ring terminals for protection against oxidation and corrosion; Rugged PVC jacket and insulation provide ultimate protection;
- Multipurpose & Compatible: 4 AWG battery cable set can be used for car, vehicle, truck, RV, campers, solar application, boat and more, also used for other electrical equipment. Ideal for DC applications that involve batteries where pure copper is recommended.
- Easy to Use – Pro grade battery cables has two 3/8 inch tinned copper ring terminals allowing it to fit over battery disconnects/switches. Please carefully check all the product information to make sure this is the right one you want before purchasing

These are some good quality battery cables that can be used to connect a battery to an inverter in a solar power system or to connect multiple batteries in parallel (or series). I took 8 pictures of them, including some closeups of the printing on the red cable and showing the straightened cables with a tape measure which shows they are ~14 inches from tip to tip of the lugs.
The metal lugs are all stamped with: 4×5/16 (I assume they’re tin coated copper but I didn’t scrape off some tin to check for the copper underneath).
The printing on the red cable reads: 2023/03/14 056m
This printing on the red cable appears to be the manufacture date and a length along a big spool of wire that the red cable was cut from. I would have preferred to see some information about the gauge of the wire and the temperature rating of the insulation but this is what I got. There is no printing on the black cable, but that may be due to how short these cables are.
The cables are somewhat stiff as you might expect for this thick wire and tend to maintain their shape when held by one end, but they could be straightened easily enough.
These cables serve well for connecting a 12V battery to an inverter (preferably less than 1000W) or for connecting pair of batteries in parallel, but if you are going to exceed ~70Amps you should probably get two pairs and double up or just go with a thicker wire like 2AWG or 1/0AWG and if you are planning to exceed 100Amps then definitely double up or go with thicker wire than the 4AWG.

Normally 4AWG copper wire is good for at least 85 amps and up to 105 amps in some installations. The product description lists an operational temperature range of -5°F to +221°F (-20°C to +105°C). Maybe the insulation becomes brittle in colder temperatures and might not be suitable for outdoor uses in the winter, at least not where I live. Other than that, the cables seem to be of high quality.

The media could not be loaded.
Bought 3 set of 12″ 1/0 cables. All red cables were never crimped properly. Ends were easily rotated. Black cable ends were tight.
Be careful. Inspect or you may have issues overheating or fire.

I’ve been contacted by Bestek who have been very cooperative in resolving my complaint including offer of full replacement of the cable sets. Much credit to the customer service process of Bestek. Because of this I have increased my rating to reflect good service.

These are extremely heavy duty cables that I use to connect my LifePO4 batteries to my pure sine wave inverter. The wire gauge is accurate and is indeed copper.

These 4AWG batter cables are well made and have heat shrink covering the connections. I have no doubt they will function perfectly. It’s important when working with any kind of electrical connections that the jumper cables are sized correctly. Typically, this sized wire should handle 85 amps, however, check your system before using to ensure you don’t exceed the wire’s capacity.
R. Larson –
These cables were poorly crimped which can be a fire hazard. Especially if you are using it with a high wattage inverter which I was. Just by moving the battery the one lug came off. I decided to check the other side and it came right off with barely any effort. I couldn’t believe how easily it slid off. The wires were also nicked during the stripping process. It’s a shame as the wires themselves are made of good quality copper.
TechPicky –
As described and what I needed.

These cables are nice and floppy, so they are easy to work with. The jacket reads has no writing whatsoever on it, which may be concerning, depending on your use case.
The ends are tinned to prevent corrosion. The coating appears to be well done–I don’t see any copper underneath. The heat-shrink is also done properly, meaning it is snug against the cable and lug, not allowing the elements in. This is also very important to prevent corrosion, albeit of a different nature.
Overall, these are well-made cables. 5 stars, thanks!

Pros:
• Quality heavy cable
• Heavy lugs 5/16” – perfect fit for 29DC battery terminals
• Heat-shrink tubing over crimp area of lugs
Cons:
• No wire markings for gauge, temperature, or Voltage
This pair of RED and BLACK 4 AWG cables appear to be very well made, heavy-duty cables. The lugs are 5/16” inch and solid. They are a perfect fit for the terminals of a 29DC deep-discharge marine battery. The terminal ends are obviously crimped and covered with heat shrink tubing.
The wire has no markings on it at all. While they seem like 4 AWG cables, it is difficult to know if it really meets the specifications. There are also no temperature or insulation Voltage ratings shown. It is also difficult to fully know without removing either insulation or heat shrink if these are 100% copper wire as claimed. I have not removed either at this point.
These will be used these to parallel connect multiple 29DC marine deep storage batteries for use with a 1000-Watt inverter. These appear perfectly suited to this application, and I will likely purchase additional pairs for additional batteries.
