What This System Is

The ETHOS platform is a modular LiFePO4 (Lithium Iron Phosphate) battery system from BigBattery, sold here as a kit alongside a 6000XP inverter. This page represents the parent listing for the system — it covers a scalable capacity range (5.12kWh to 30.72kWh) rather than a single fixed configuration. Because manufacturer specification sheets carry the authoritative per-module Ah, voltage, BMS discharge/charge limits, cycle life, and dimension data, and those figures were not included in the source data provided for this draft, we're flagging them below for verification rather than guessing.

Wiring & Configuration Limits (Series/Parallel)

The ETHOS system is described by the manufacturer as a stackable, modular platform, and the product includes a dedicated junction box kit and controller cables (shown in the product images) that suggest multi-module parallel expansion is supported. However, the source data for this listing does not specify the maximum number of modules that can be wired in series or parallel, nor the exact voltage bus the system operates on. Do not assume a series or parallel configuration limit — confirm the exact wiring diagram and module count limits against the manufacturer's documentation before ordering additional modules or connecting multiple units.

NOT confirmed for this listing: maximum series count, maximum parallel count, mixed-capacity stacking, and compatibility with inverters other than the one included in this kit. Do not wire ETHOS modules with other battery brands or with lead-acid batteries in the same bank.

Pro-Installer Tip

Stacking lithium modules without matching state-of-charge across every unit is a common cause of BMS lockout on install day. When paralleling ETHOS modules, bring each one to the same resting voltage before joining them to the bus bar — a mismatch invites the BMS on the lower-charged unit to see the higher-charged unit as an overcurrent event and trip offline. This kind of imbalance also accelerates cell divergence over time, shortening the pack's usable life well before it reaches its rated cycle count. Use a shunt-based battery monitor on the combined bank so you can verify true system voltage and current flow, not just an individual module's screen. As a professional standard, plan your daily discharge around 80–100% DoD for LiFePO4 chemistry — but confirm that figure against the ETHOS spec sheet under the Resources tab before designing your daily load budget, since it was not part of the data provided here.

Key Benefits

• Modular, stackable LiFePO4 design intended for scalable off-grid capacity (5.12kWh–30.72kWh per this listing)
• Packaged with a matching inverter, junction box kit, and stackable-type module kit — reduces separate sourcing decisions
• LiFePO4 chemistry generally offers longer cycle life and lighter weight than lead-acid alternatives, though exact cycle-life and weight figures for this SKU are not in the provided data and should be confirmed via the Resources tab

Compatibility & Fitment

This kit is sold as a matched battery-and-inverter package. It is intended for off-grid power system builds where the included components are designed to work together.

Positive fitment: The kit includes ETHOS battery modules, a junction box kit, a stackable-type module kit, and controller cables — components intended to be used together as shipped.

Negative fitment / NOT included or NOT compatible:

• NOT confirmed for use with lead-acid chargers — standard lead-acid chargers are NOT recommended for LiFePO4 packs unless the manufacturer explicitly states otherwise.
• NOT to be mixed with other battery chemistries (AGM, Gel, Flooded) in the same bank.
• Series/parallel expansion beyond the tested configuration is NOT confirmed in this data — check manufacturer documentation before adding modules.
• Exact inverter model, communication protocol, and compatible accessory list are NOT specified in the source data for this draft — confirm via the Resources tab.
