Lightweight, long-life, and temperature-resilient battery packs purpose-built for mobile, off-grid and smart HVAC condenser systems.
With the global trend toward energy-efficient and portable HVAC systems, reliable DC power solutions are becoming essential. Air conditioner condensers—especially for RV A/C, portable cooling units, and solar-powered HVAC—demand compact packs with high efficiency, stable output, and strong protection.
Application Background
Condenser subsystems (compressor, fan motor, control board) require continuous, stable DC power. Compared with lead-acid, prismatic lithium packs offer:
- Higher energy density and discharge efficiency
 - Wide working temperature and better high-temp endurance (up to 55–60 °C)
 - Long cycle life (>2000 cycles typical for LiFePO4)
 - Stable voltage with robust BMS/PCM

FAQ
Can the pack handle compressor inrush current?
Yes. We configure cell IR, busbar design, and BMS current limits for safe startup. High-pulse capability can be validated on your compressor profile.
Which chemistry should I choose for condensers?
Choose LiFePO4 for safety and cycle life; NCM for tighter space with higher energy density. We can simulate runtimes for both.
What about operation in high ambient temperatures?
Designs target up to 55–60 °C ambient with appropriate derating. We recommend thermal paths and enclosure options for hot compartments.
Do you support certifications?
Yes. Packs are designed for UN38.3 transport; CE/IEC62133 per project needs. We assist with test plans and documentation.
