   Solid 4 gauge battery cables! The 21″ length is ideal for tight battery box setups. Quality copper core, thick insulation, and pre-crimped lugs saved me time. Great deal for a 5-pack—no complaints.

   Bought these for wiring up my 48V golf cart battery bank. The cables are heavy-duty and flexible enough for tight spaces. Would’ve given 5 stars if they were color-coded red/black.

   Super fast shipping! Got the bag of 5 black 21″ 4 AWG cables in two days. Used them for a solar inverter project—no heat buildup even under load. Definitely true copper, not aluminum.

   Anyone know if these 4 gauge battery cables are suitable for marine use? They look sturdy, but I’m unsure if the insulation is UV and saltwater resistant. Just want to double-check before installing.

   Used these to connect deep cycle batteries in parallel. The 4 gauge wire is thick and the crimped ends are tight with heat shrink already done. Best price I found for a 5-pack of 21″ cables.

   These 4 AWG battery cables are exactly what I needed for my lithium battery setup in my van build. The 21″ length is just right for interconnects, and they feel premium. No voltage drop, even under heavy load.

   Great deal on a bag of 5 pre-cut battery cables. Used them for a backup battery bank on my property. They’re thick, flexible, and easy to route. Would’ve loved an option to buy mixed red and black.
