How Does the DEESPAEK 36V 100Ah LiFePO4 Battery Work?
This battery uses lithium iron phosphate (LiFePO4) chemistry, which stabilizes electron flow through a crystalline structure. During discharge, lithium ions move from the anode to cathode via an electrolyte, generating 36V/100Ah output. A built-in Battery Management System (BMS) monitors temperature, voltage, and current to prevent overcharging, deep discharging, and short circuits, ensuring optimal performance across -20°C to 60°C temperatures.
The proprietary electrode design employs nano-structured lithium iron phosphate particles coated with conductive carbon, reducing internal resistance to just 18mΩ. This enables 98% Coulombic efficiency during partial state-of-charge cycling. The battery’s pulse discharge capability reaches 300A for 30 seconds, making it suitable for high-torque motor starts. Its self-discharge rate of 3% per month is 60% lower than conventional lithium-ion batteries, preserving energy during storage periods.
What Are the Advantages Over Traditional Lead-Acid Batteries?
| Feature | DEESPAEK LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 3,000+ cycles | 300-500 cycles |
| Energy Density | 125 Wh/kg | 30-50 Wh/kg |
| Charge Efficiency | 95% | 70-85% |
Compared to lead-acid batteries, the DEESPAEK LiFePO4 model provides 4x greater cycle life (3,000 vs. 800 cycles), 50% higher energy density, and 95% round-trip efficiency. It operates maintenance-free, charges 3x faster, and retains 80% capacity after 2,000 cycles. Unlike lead-acid, it contains no toxic lead or acid, reducing environmental hazards and disposal costs.
How Does It Perform in Extreme Temperatures?
At -20°C, the battery delivers 85% rated capacity using internal heating pads. High-temperature performance (60°C) is maintained via aluminum cooling fins that dissipate 120W of heat. Humidity resistance up to 95% RH non-condensing ensures reliability in tropical climates. Cold-cranking amps (CCA) reach 1,000A for engine starts.
The battery’s thermal management system uses 12 NTC sensors distributed throughout the cells, providing real-time temperature mapping. In arctic conditions, the integrated heating coils activate at -10°C, drawing 40W to maintain optimal operating temperatures. For desert environments, the phase-change material in the casing absorbs 150kJ of thermal energy during peak loads, preventing performance throttling.
“The DEESPAEK 36V 100Ah sets a new benchmark for LiFePO4 technology. Its hybrid graphene anode coating reduces internal resistance to just 18mΩ, enabling 98% energy efficiency at 0.5C discharge rates. For large-scale solar installations, we’ve seen ROI periods drop below 4 years thanks to its cycle durability.”
