Specifications Breakdown

Usable Storage Capacity

The SOK Battery 12V 100Ah LiFePO4 provides 1.02 kWh of usable capacity (1.28 kWh total, 80% DoD), while the Pytes V5° offers 5.12 kWh usable (5.12 kWh total, 100% DoD). At an average essential-load consumption rate of 750 watts, the SOK Battery 12V 100Ah LiFePO4 provides approximately 1.4 hours of backup versus 6.8 hours for the Pytes V5°. The Pytes V5°'s 4.1 kWh capacity advantage translates to roughly 5 additional hours of essential-load backup during a grid outage. The SOK Battery 12V 100Ah LiFePO4 is scalable up to 4 units (4 kWh total), while the Pytes V5° scales up to 16 units (82 kWh total).

Power Output

The SOK Battery 12V 100Ah LiFePO4 delivers 1.28 kW continuous and 1.92 kW peak power, while the Pytes V5° provides 2.56 kW continuous and 5.12 kW peak. The Pytes V5°'s higher continuous output means it can simultaneously power more demanding appliances during an outage. A central air conditioner typically draws 3-5 kW, a refrigerator 0.1-0.2 kW, and an EV Level 2 charger 7-11 kW. Peak power rating matters for motor-driven loads with high startup current, such as air conditioners, well pumps, and sump pumps. The Pytes V5°'s 5.12 kW peak is suitable for lighter startup loads.

Battery Chemistry & Cycle Life

The SOK Battery 12V 100Ah LiFePO4 uses LFP chemistry with a rated cycle life of 4,000 cycles (approximately 11.0 years of daily cycling), while the Pytes V5° uses LFP with 6,000 cycles (approximately 16.4 years). Both use LFP chemistry, which is considered the gold standard for residential energy storage due to its inherent safety, long cycle life, and environmental friendliness. The Pytes V5°'s additional 2,000 cycles translates to approximately 5.5 more years of daily use before reaching the rated end of life.

Round-Trip Efficiency

The SOK Battery 12V 100Ah LiFePO4 achieves 96% round-trip efficiency versus 95% for the Pytes V5°. This means for every 10 kWh of solar energy stored in the SOK Battery 12V 100Ah LiFePO4, 9.6 kWh is recoverable, compared to 9.5 kWh for the other. Over 10 years of daily cycling with 15 kWh average daily throughput, the more efficient battery saves approximately $82 in energy that would otherwise be lost as heat (at $0.15/kWh average retail rate). Higher round-trip efficiency is especially valuable in time-of-use rate environments where you are storing cheap off-peak energy for expensive peak-hour consumption.

Warranty & Long-Term Protection

The SOK Battery 12V 100Ah LiFePO4 carries a 5-year warranty, while the Pytes V5° offers 10 years. The Pytes V5° provides 5 additional years of manufacturer protection against capacity degradation and defects. Battery warranties typically guarantee the unit will retain 60-70% of original capacity by end of warranty, so the length of coverage directly impacts your financial risk over the system's lifetime.
