One series link and one parallel pair are not the same purchase

A single cable can make one series connection. A parallel connection normally needs both positive and negative conductors, so confirm the bank diagram and required cable quantity before ordering.

Why this Renogy product

A finished short cable for compact battery layouts

Factory-crimped lugsPre-installed M8 ring terminals avoid field-crimping this short interconnect.
Tinned copperRenogy specifies tin-coated copper conductors for corrosion resistance in supported installations.
Compact routingThe 12 in length limits unnecessary cable in adjacent-battery arrangements.

System fit

Use identical cable paths and batteries in a balanced bank.

Confirm cable ampacity for the bank current, temperature and installation method. Use matching batteries and protect the overall bank according to battery and equipment instructions; this short cable does not replace the main bank fuse.

Terminal fitThe 5/16 in lugs are intended for M8 studs. Verify every battery terminal before purchase.
Bank balanceParallel banks benefit from equal-length, equal-gauge positive and negative paths so current shares more evenly.

Common questions

Buyer FAQ

Does the listing include one cable or a pair?

It includes one cable. Check your bank diagram to determine whether you need one or multiple interconnects.

Will it fit 3/8 in studs?

The listed lugs are 5/16 in / M8. Do not assume they fit a larger stud correctly.

Can it connect batteries in parallel?

It can be part of a parallel bank, but parallel wiring normally requires matching positive and negative interconnect paths.

Is 4AWG large enough for my inverter?

That depends on current, cable length, temperature, bundling and equipment requirements. Size the complete circuit from the applicable manual and code.
