Specifications Breakdown
Usable Storage Capacity
The Docan Power 48V 100Ah Server Rack LiFePO4 provides 4.1 kWh of usable capacity (5.12 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 Docan Power 48V 100Ah Server Rack LiFePO4 provides approximately 5.5 hours of backup versus 6.8 hours for the Pytes V5°. The Pytes V5°'s 1.0 kWh capacity advantage translates to roughly 1 additional hours of essential-load backup during a grid outage. The Docan Power 48V 100Ah Server Rack LiFePO4 is scalable up to 16 units (66 kWh total), while the Pytes V5° scales up to 16 units (82 kWh total).
Power Output
The Docan Power 48V 100Ah Server Rack LiFePO4 delivers 5.12 kW continuous and 7.68 kW peak power, while the Pytes V5° provides 2.56 kW continuous and 5.12 kW peak. The Docan Power 48V 100Ah Server Rack 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 Docan Power 48V 100Ah Server Rack LiFePO4's 7.68 kW peak is suitable for lighter startup loads.
Battery Chemistry & Cycle Life
The Docan Power 48V 100Ah Server Rack LiFePO4 uses LFP chemistry with a rated cycle life of 6,000 cycles (approximately 16.4 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. Identical cycle ratings mean both batteries have the same expected operational lifespan under daily cycling.
Round-Trip Efficiency
The Docan Power 48V 100Ah Server Rack LiFePO4 achieves 95% round-trip efficiency versus 95% for the Pytes V5°. 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 Docan Power 48V 100Ah Server Rack 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.
