This parallel cable ties one BB175 battery to two BB50 batteries so the group works as a single power bank. It's built for BigBattery owners who need a fixed, correctly-sized connection between mismatched battery models rather than a generic cable off the shelf.
BigBattery designs these parallel cables specifically to move current between named battery models rather than as a universal 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.
Critical Fitment & Requirements
- Designed to connect (1) BigBattery BB175 to (2) BigBattery BB50 batteries in a single parallel bank.
- Single SKU (CBL024) covers the full cable assembly for this pairing.
- Wire gauge, terminal lug size, cable length, voltage rating, and ampacity limit are not stated in the manufacturer data provided — confirm these figures against the manufacturer spec sheet in the Resources tab before purchase or installation. [NEEDS VERIFICATION]
- NOT confirmed for use with BigBattery models other than BB175 and BB50 — do not substitute onto other battery pairings without verifying pinout and current rating.
- NOT a communication or data cable — this is a DC power parallel cable only.
Parallel wiring between differently-rated batteries like a BB175 and two BB50 units creates uneven current paths if any lug connection is loose — that resistance imbalance shows up as heat at the terminal first, long before you see a fault code on the inverter. Torque every lug to the manufacturer's spec and re-check it after the first thermal cycle, since crimped and bolted connections settle as insulation and hardware expand and contract. Verify each connection with a digital torque wrench rather than "hand tight plus a quarter turn" — that habit is the single most common cause of hot-spot failures in parallel battery banks. Confirm your torque value and wire ampacity against the manufacturer's documentation and NEC ampacity guidance before energizing the bank.
Key Benefits
- Purpose-built to bridge a BB175 and two BB50 batteries — no field-modifying a universal cable to fit.
- Single-SKU assembly simplifies ordering: one part number for the full BB175-to-BB50 parallel run.
- Manufactured by BigBattery for use across its own battery lineup, reducing pinout guesswork.
- Straightforward drop-in replacement part if an existing parallel cable is damaged or needs duplicating.

FAQ
What batteries does this parallel cable connect?
It connects one BigBattery BB175 to two BigBattery BB50 batteries, wiring them into one parallel bank.
Will this cable work with other BigBattery models?
This is not confirmed. The manufacturer data provided names only the BB175 and BB50 as the intended pairing, so fitment with other BigBattery models is not verified here.
What gauge wire and terminal size does this cable use?
This detail is not specified in the manufacturer data provided. Check the Resources tab for the manufacturer's full specification sheet before installing.
Is this a single-cable or multi-cable assembly?
It ships as one part number, CBL024, sized to bridge one BB175 unit to two BB50 units in parallel.
Warranty & Registration
Manufacturer warranty terms for this cable are not stated in the data provided. Refer to the "Resources (System Manuals and Warranty)" Tab above on this page for the manufacturer's current warranty terms and registration requirements before installation.
