Specifications Breakdown
Usable Storage Capacity
The Eco-Worthy 12V 100Ah LiFePO4 provides 1.02 kWh of usable capacity (1.28 kWh total, 80% DoD), while the Pylontech Force-H2 offers 6.75 kWh usable (7.1 kWh total, 95% DoD). At an average essential-load consumption rate of 750 watts, the Eco-Worthy 12V 100Ah LiFePO4 provides approximately 1.4 hours of backup versus 9.0 hours for the Pylontech Force-H2. The Pylontech Force-H2's 5.7 kWh capacity advantage translates to roughly 8 additional hours of essential-load backup during a grid outage. The Eco-Worthy 12V 100Ah LiFePO4 is scalable up to 4 units (4 kWh total), while the Pylontech Force-H2 scales up to 12 units (81 kWh total).
Power Output
The Eco-Worthy 12V 100Ah LiFePO4 delivers 1.28 kW continuous and 1.92 kW peak power, while the Pylontech Force-H2 provides 3.55 kW continuous and 7.1 kW peak. The Pylontech Force-H2'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 Pylontech Force-H2's 7.1 kW peak is suitable for lighter startup loads.
Battery Chemistry & Cycle Life
The Eco-Worthy 12V 100Ah LiFePO4 uses LFP chemistry with a rated cycle life of 3,000 cycles (approximately 8.2 years of daily cycling), while the Pylontech Force-H2 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 Pylontech Force-H2's additional 3,000 cycles translates to approximately 8.2 more years of daily use before reaching the rated end of life.
Round-Trip Efficiency
The Eco-Worthy 12V 100Ah LiFePO4 achieves 95% round-trip efficiency versus 95% for the Pylontech Force-H2. Identical round-trip efficiency means both batteries lose the same proportion of stored energy to heat during each charge-discharge cycle. 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 Eco-Worthy 12V 100Ah LiFePO4 carries a 5-year warranty, while the Pylontech Force-H2 offers 10 years. The Pylontech Force-H2 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.
