- Modular “stack” design stacks up to 6 units vertically—no separate racks/cabinets needed—plus parallel capability for expandable capacity.
- Impactive balancing + built‑in RPSD extends lifespan by up to 30%; rated for 6,000 cycles at 80 % DoD with 12‑year warranty.
- Enclosed cabling & networking compartment + casters for clean, safe installation and mobility.
- UL9540A certified (RGS51100) and UN38.3 transport certified, with BMS safety cut‑outs and breach‑vented cells.
Product Overview
Upgrade your energy storage with the Rubix Giga Stack Series RGS51100. This high-performance 48 V, 100 Ah LiFePO₄ battery delivers 5.12 kWh of usable energy in a compact, stackable form factor—ideal for off-grid systems, residential backup, RVs, or commercial applications. Built by a joint venture between MillerTech and ARK Battery, Rubix brings installer-focused design, quality manufacturing, and hands-on support.
The modular stacking system functions like giant LEGO bricks—stack up to six units vertically without racks, and parallel stacks to scale with demand. A solid base and lid package (sold separately) ensures a secure foundation and clean cable management.
Your system intelligence lives in the touchscreen LCD: view key metrics like SOC%, voltage, amps in/out, balancer status, cell-level voltages, and fault codes—all at a glance.
Performance-wise, RGS51100 supports continuous discharge at 90 A (recommended 75 A), peak discharge up to 200 A surge, and continuous charging at 70 A (peak 80 A). The robust LiFePO₄ prismatic cells and impactive balancing deliver up to 6,000 full cycles at 80 % DoD (or 8,500 cycles at 50 % DoD), with an 80 % end-of-life capacity guarantee—backed by a 12-year warranty.
Safety is baked in: the integrated BMS includes low/high voltage cut-offs, over-current protection, over temperature safeguards up to 135 °F, and ruptured-cell venting. The stack supports closed-loop CANBUS inverter communication to optimize EQ, absorb and float charging protocols .
This model is UL9540A certified and UN38.3 approved for shipping. Housed in an IP50 enclosure, it is recommended for dry, climate-controlled indoor deployment
