LiFePO4 Battery | 51.2V 560AH | 28.67kWh | 8000+ Cycles
GRANKIA GLM56051 28.67kWh Lithium Iron LiFePO4 Battery 51.2V 560Ah represents a paradigm shift in utility-scale and commercial energy storage. Engineered specifically as a heavy-duty, high-density system, this lithium iron lifepo4 battery directly addresses infrastructure vulnerabilities by pairing massive capacity (28.67kWh) with a safe, low-voltage, high-current design (51.2V, 560Ah).
As a lithium iron LiFePO4 battery, the GLM56051 inherits the core advantages that have made LiFePO4 chemistry the dominant choice for stationary and heavy-duty energy storage worldwide: exceptional thermal and chemical stability, a flat discharge curve, and a dramatically longer service life than lead-acid or cobalt-based lithium-ion alternatives.
Anyone who has managed an off-grid solar array, a commercial backup power system, or a high-demand industrial energy bank knows the same recurring frustrations. Lead-acid banks degrade fast, lose usable capacity below 50% depth of discharge, and need constant maintenance.
Many lithium battery packs on the market today are undersized for serious daily cycling, forcing installers to wire multiple smaller units together — adding complexity, points of failure, and wasted rack space.
And even among lithium options, not all chemistries are equal: some prioritize energy density over safety, which becomes a real liability in residential basements, telecom shelters, or enclosed commercial spaces.
The result is a familiar set of pain points for installers, integrators, and facility managers:
This is precisely the gap the GLM56051 28.67kWh lithium iron LiFePO4 battery 51.2V 560Ah was engineered to close.

Powered by premium Prismatic LiFePO4 cells, the system delivers an exceptional cycle life of 8,000+ cycles @90% DoD, ensuring over 15 years of reliable operation and maximizing your long-term return on investment.
Boasting a high single-unit capacity of 560Ah at a 51.2VDC rated voltage, this battery pack packs 28.67kWh of nominal energy. It easily supports a continuous maximum output power of 14.33kW to handle heavy loads effortlessly.
Designed to grow with your power demands, the system supports the parallel connection of up to 15 units, scaling the total energy expansion up to a massive 430.08kWh. Perfect for heavy residential, commercial, and industrial (C&I) applications.
Features an integrated BMS with Active Cell Balancing to ensure all cells maintain optimal uniformity. It provides comprehensive safety protections (overcharge, over-discharge, over-current, short circuit, and over-temperature) along with precise SOC and SOH estimation.
Housed in a rugged metal enclosure with a space-saving floor-standing design. Despite its robust weight, the integrated heavy-duty wheels enable smooth indoor positioning and hassle-free installation.
