Specifications Breakdown
Usable Storage Capacity
The Docan Power 48V 200Ah Server Rack LiFePO4 provides 8.19 kWh of usable capacity (10.24 kWh total, 80% DoD), while the Pytes E-Box 48100R 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 200Ah Server Rack LiFePO4 provides approximately 10.9 hours of backup versus 6.8 hours for the Pytes E-Box 48100R. The Docan Power 48V 200Ah Server Rack LiFePO4's 3.1 kWh capacity advantage translates to roughly 4 additional hours of essential-load backup during a grid outage. The Docan Power 48V 200Ah Server Rack LiFePO4 is scalable up to 16 units (131 kWh total), while the Pytes E-Box 48100R scales up to 16 units (82 kWh total).
Power Output
The Docan Power 48V 200Ah Server Rack LiFePO4 delivers 10.24 kW continuous and 15.36 kW peak power, while the Pytes E-Box 48100R provides 2.56 kW continuous and 5.12 kW peak. The Docan Power 48V 200Ah 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 200Ah Server Rack LiFePO4's 15.36 kW peak is capable of starting most residential HVAC systems.
Battery Chemistry & Cycle Life
The Docan Power 48V 200Ah 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 E-Box 48100R 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 200Ah Server Rack LiFePO4 achieves 95% round-trip efficiency versus 95% for the Pytes E-Box 48100R. 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 200Ah Server Rack LiFePO4 carries a 5-year warranty, while the Pytes E-Box 48100R offers 10 years. The Pytes E-Box 48100R 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.
