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 Eco-Worthy 12V 200Ah LiFePO4 offers 2.05 kWh usable (2.56 kWh total, 80% 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 2.7 hours for the Eco-Worthy 12V 200Ah LiFePO4. The Eco-Worthy 12V 200Ah LiFePO4's 1.0 kWh capacity advantage translates to roughly 1 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 Eco-Worthy 12V 200Ah LiFePO4 scales up to 4 units (8 kWh total).

Power Output

The Eco-Worthy 12V 100Ah LiFePO4 delivers 1.28 kW continuous and 1.92 kW peak power, while the Eco-Worthy 12V 200Ah LiFePO4 provides 2.56 kW continuous and 3.84 kW peak. The Eco-Worthy 12V 200Ah LiFePO4'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 Eco-Worthy 12V 200Ah LiFePO4's 3.84 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 Eco-Worthy 12V 200Ah LiFePO4 uses LFP with 3,000 cycles (approximately 8.2 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. Identical cycle ratings mean both batteries have the same expected operational lifespan under daily cycling.

Round-Trip Efficiency

The Eco-Worthy 12V 100Ah LiFePO4 achieves 95% round-trip efficiency versus 95% for the Eco-Worthy 12V 200Ah LiFePO4. 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 Eco-Worthy 12V 200Ah LiFePO4 offers 5 years. Both offer identical warranty duration. 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.
