Prismatic LiFePO4 aku rakud 280Ah 3.2V päikeseenergia salvestamiseks, skaleeritavad 12V/24V/48V süsteemid, 7500 tsüklit
Meet the Tewaycell 3.2V 280Ah LiFePO4 battery prismatic cells, engineered for scalable solar energy storage in 12V, 24V, and 48V systems. Each cell is Grade A with CE certification, delivering a nominal 3.2V and 280Ah capacity with an impressive life of up to 7500 cycles. Built on LiFePO4 chemistry for safety, stability, and wide operating temperature, these modules minimize maintenance while delivering reliable energy for off‑grid homes, microgrids, and solar installations. The compact prismatic form (174 × 72 × 203 mm) and light weight (~5.3 kg) simplify rack mounting and wiring. Set Type: Batteries Only, with options for 4/8/16/32 pieces; busbars and M6 screws are included per battery for quick assembly. They are designed to perform reliably across climates from -20 to 60°C.
Benefits & Tips
- Long-lasting, safe LiFePO4 chemistry provides stable voltage, excellent cycle life, and lower risk of thermal runaway—ideal for continuous solar storage and backup power.
- Modular design makes it easy to scale a solar or off‑grid system from 12V to 24V or 48V by wiring cells in series/parallel, while keeping a compact footprint.
- Operate within recommended temp range and follow charging/discharging guidelines: charging voltage 3.65V, maximum continuous discharge 280A (1C), and a discharge end voltage of 2.5V to protect longevity.
