The ETHOS Parallel Kit is a cable and connector accessory set for linking multiple ETHOS rack batteries together. It is not a battery, and it does not store or generate power on its own — it is the hardware that lets compatible ETHOS rack units share a common power bus and communication line.
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.
Why This Kit Matters
Wiring battery racks together isn't just a matter of running any cable you have on hand. Rack power cables and communication cables carry specific current loads and data signals between units. Using the manufacturer-matched kit keeps voltage sag, connector wear, and communication errors out of the picture when you're expanding an ETHOS rack system.
Kit Characteristics
This is an accessory kit, not a standalone power source. Based on the images provided, the kit includes a red/black rack power cable, a rack-to-rack communication cable, and an ETHOS rack base component. Exact counts of each item, cable gauge, length, and connector type are [NEEDS VERIFICATION].
Wiring & Configuration Limits
This kit is designed to support parallel connection of compatible ETHOS rack batteries, allowing multiple units to share load on a common bus. Specific maximum parallel unit count, series wiring support, and voltage/amperage ratings for the included cables are [NEEDS VERIFICATION] — refer to the Resources tab for manufacturer-published configuration limits before wiring any rack system.
Do not use this kit to wire batteries in series unless the ETHOS system documentation explicitly confirms series compatibility for your specific rack model. Do not substitute third-party power or communication cables in place of kit components without confirming pinout and current rating compatibility.
Pro-Installer Tip
Parallel-wired rack batteries are unforgiving of mismatched cable runs — a longer or thinner run to one rack than another creates unequal resistance, and unequal resistance means unequal current draw between units over time. That imbalance accelerates cell wear in whichever battery is working harder, even if every unit in the bank is the same age and model. Use a shunt-based battery monitor on the combined bus to watch for current drift between racks rather than relying on voltage alone — voltage alone won't show you an imbalance until it's already advanced. As a professional standard, treat any parallel bank the same way you'd treat a single large battery: match cable lengths and gauges rack to rack, and confirm the system's rated depth of discharge (per the ETHOS documentation) before setting your daily cycling routine.
Key Benefits
- Manufacturer-matched cabling reduces guesswork when expanding an ETHOS rack bank.
- Dedicated communication cable supports rack-to-rack data sharing (specific protocol [NEEDS VERIFICATION]).
- Rack base component included for physical mounting/stacking support.

Compatibility & Fitment
This kit is intended for use with BigBattery ETHOS rack battery systems. It is NOT a universal battery interconnect kit — it is not confirmed compatible with non-ETHOS battery lines, golf cart batteries, or marine/RV single-unit batteries. It does NOT include a battery, charger, or inverter. It does NOT include mounting hardware beyond the rack base pictured, unless otherwise confirmed. Confirm your specific ETHOS rack model number against the manufacturer's compatibility list in the Resources tab before ordering.
FAQ
Is this kit a battery?
No. The ETHOS Parallel Kit is a cable and connector accessory set. It does not store or supply power on its own.
Can I use this kit to wire ETHOS batteries in series?
Series wiring support is not confirmed in the available data. Check the manufacturer documentation in the Resources tab before attempting a series configuration.
Does this kit include the rack battery itself?
No. This is an accessory kit only. Rack batteries must be purchased separately.
Will this kit work with non-ETHOS BigBattery products?
Compatibility is stated only for ETHOS rack battery systems. Use with other product lines is not confirmed.
Warranty & Support
Warranty terms for this kit are covered under the manufacturer documentation — see the "Resources (System Manuals and Warranty)" Tab above for full details. If you have questions about whether this kit matches your ETHOS rack configuration, ask us before you order. We always reply back.
