This is a parallel wiring cable that lets you connect one BB175 battery to up to four BB50 batteries so they work together as one power bank. It's built for BigBattery owners who need to combine battery models within a compatible system rather than run separate wiring runs by hand.
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 designs this cable specifically for parallel wiring between its BB50 and BB175 battery models. Matching OEM-designed cabling to the battery family it was built for reduces the risk of loose fit at the terminal, a common cause of resistance-driven heating in multi-battery parallel banks.
Critical Fitment & Requirements
- Connects (1) BB175 battery to (4) BB50 batteries in a parallel run
- Designed for BigBattery BB50 and BB175 battery models only
- NOT verified for use with other BigBattery battery models outside the BB50/BB175 family
- NOT verified for use with third-party or other-brand battery systems
- Wire gauge, cable length, terminal lug size, and voltage rating are not specified in the source data [NEEDS VERIFICATION]
Parallel cable runs between multiple batteries are a common spot for uneven current sharing if any single connection is looser than the others. Over time, that imbalance causes one battery in the bank to work harder than the rest, accelerating wear and tripping inverter fault codes tied to voltage imbalance. Check every lug connection with a digital torque wrench against the terminal manufacturer's spec before the system goes into service, and re-check torque after the first thermal cycle. Confirm this against the torque spec listed in the "Resources (System Manuals and Warranty)" tab before final commissioning.
Key Benefits
- Purpose-built parallel cable for BB50-to-BB175 battery combinations
- Simplifies wiring a mixed BB50/BB175 bank into one connected system
- Designed by BigBattery for direct fitment to its own battery terminals
- Removes the guesswork of sourcing generic aftermarket parallel cabling
