This cable connects a BigBattery BB50 connector to a ring terminal lug, giving you a secure hard-wired link between your battery and system components. It's built for BigBattery lithium-ion setups where you need a fixed, low-resistance connection instead of a plug-and-play cable.
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.
BigBattery builds this cable with 6 AWG wire to keep resistance low and current flow steady between your battery and connected components. The ring terminal end and acrylic-cased BB50 connector are meant to give you a stable connection point that resists loosening or arcing over time. This is a fixed-length assembly, not a bulk cable — length and terminal type are fixed at 3 feet.
- Wire gauge: 6 AWG copper conductor
- Length: 3 feet (fixed)
- Termination: BB50 connector on one end, ring terminal on the other
- Connector housing: Acrylic casing at the BB50 end
- Does NOT include: A ring terminal lug size specification — verify your bus bar or stud size matches before ordering [NEEDS VERIFICATION]
- Does NOT carry: A published voltage or ampacity rating in manufacturer data — confirm suitability for your system's continuous draw before install [NEEDS VERIFICATION]
- NOT confirmed compatible with battery connectors other than BigBattery's BB50 interface
A ring terminal that isn't torqued to spec on the bus bar side is a common source of resistance heating in 6 AWG runs carrying repeated high-current draws. Loose lugs create a hot spot that degrades insulation over time and can trigger voltage-sag fault codes on sensitive inverters. Check the ring terminal connection with a digital torque wrench set to the bus bar or terminal manufacturer's spec, not just "snug by feel." This matches the practice outlined in NEC guidance on proper lug torque for current-carrying conductors — don't skip it just because the cable arrived pre-terminated.
- 6 AWG copper conductor sized for the BB50-to-ring-terminal connection path
- Fixed BB50 connector with acrylic housing for a secure mechanical connection
- Pre-terminated ring terminal end for direct hard-wire connection to a bus bar or lug
- Assembled specifically for BigBattery lithium-ion battery system architecture
- Fixed 3-foot length eliminates field-crimping variability on this run
