This 4-foot, 4 AWG cable connects a BigBattery BB350 terminal to a ring terminal lug, so you can wire a battery straight into a busbar or the rest of your power system without splicing or crimping your own ends.

BB350 to ring terminal cables are built for connecting battery banks directly to a busbar or distribution point, cutting out a field-crimped connection that could loosen or corrode over time. The 4 AWG conductor is sized for BigBattery's BB350 terminal system rather than generic ring-to-ring wiring runs. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.

  • Gauge: 4 AWG conductor
  • Length: 4 ft, fixed (not adjustable or field-cuttable per listed data)
  • Termination: BB350 terminal on one end, ring terminal on the other
  • Designed for BigBattery BB350-terminal battery connections to busbar or system wiring
  • NOT a universal cable — will not mate with batteries or equipment lacking a BB350-style terminal
  • No voltage or ampacity rating was provided in manufacturer data; do not assume a system voltage without confirming from the Resources tab
Pro-Installer Tip: A BB350 connector that isn't fully seated creates resistance at the joint, and resistance under load turns into heat — repeated heat cycling is what eventually degrades a terminal connection and trips inverter fault codes. Before closing up the compartment, check the BB350 end for a firm, flush seat and confirm the ring terminal lug is torqued to the hardware manufacturer's spec using a digital torque wrench rather than "hand tight." Reference NEC guidance on terminal and lug torque values as your professional standard, and re-check torque after the first thermal cycle (a day or two of normal charge/discharge) since new connections can settle.
  • 4 AWG copper conductor sized for BB350 terminal battery connections
  • Factory-terminated BB350 and ring terminal ends reduce field-crimping error
  • Fixed 4 ft length simplifies battery-to-busbar runs without excess slack
  • Purpose-built for BigBattery systems using the BB350 terminal standard

FAQ

What size are the terminal lugs?
One end terminates in a BB350 terminal connector, the other end in a ring terminal, on 4 AWG cable.

Is this cable rated for 48V systems?
The manufacturer data provided does not list a voltage rating for this cable. [NEEDS VERIFICATION]

Will this cable work with non-BigBattery batteries?
Only if that battery uses a BB350-style terminal on the matching side. It is not a universal fit for other terminal styles.

What length is this cable?
