280Ah Capacity LiFePO4 Battery Cell with 8000 Cycles and 1C Discharge for EV ESS
Manufactured by Jianheng (Shenzhen Jianheng Technology Co Ltd), the OID71173204F280AH is a high-capacity prismatic LiFePO4 battery cell designed for demanding energy storage and electric vehicle applications. With a nominal voltage of 3.2V and a massive 280Ah capacity, this cell delivers reliable power, exceptional cycle life, and outstanding thermal stability.
Engineered with advanced lithium iron phosphate chemistry, the OID 280Ah cell ensures intrinsic safety, low impedance (≤0.25mΩ), and excellent performance across a wide temperature range (-30°C to 60°C). Whether you are building a residential solar ESS, an industrial UPS, or an electric bus, this Grade A cell provides the durability and energy density you need.
- Ultra-Long Cycle Life: 8000 cycles @ 196Ah (80% SOH) – reduces total cost of ownership.
- High Power Capability: 1C continuous charge and discharge current (280A) – fast charging and high load support.
- Wide Temperature Range: Charge from 0°C to 60°C, discharge from -30°C to 60°C – suitable for extreme environments.
- Low Self-Discharge: ≤2% per month – long shelf life.
- Robust Mechanical Design: Aluminum case with positive polarity shell – enhanced structural integrity.
- Safe & Reliable: Built-in overcharge, over-discharge, and short circuit protection via BMS.

Each OID71173204F280AH cell is 100% tested for capacity, impedance, and insulation resistance (≥1GΩ @ 500V). The cell meets international safety standards and is designed with a flame-retardant electrolyte and pressure-relief vent. For system integration, a BMS (Battery Management System) is required to monitor voltage, current, and temperature as per the product specification.
