Product Description
4000 Extreme Cycles, 45A Super Power
The Jiakai 32140 LiFePO4 (Lithium Iron Phosphate) cell is a high-performance power and storage cell manufactured with top-tier processes. It features a genuine 15Ah capacity and supports a massive continuous discharge current of up to 45A (3C). Its most remarkable feature is the ultra-low internal resistance of ≤2mΩ, ensuring minimal heat generation and extremely high energy conversion efficiency during high-power operations. With an industry-leading 4000-cycle lifespan, it is the ultimate cell choice for electric tricycles, low-speed EVs, solar energy storage, and RV power systems. The 2-Pack is perfect for sample testing, parallel setups, or small-scale DIY assembly.
Key Features
- 3C (45A) Powerful Output: Supports a 45A continuous discharge current, delivering explosive power to handle heavy-load climbing and rapid acceleration scenarios with ease.
- 4000 Ultra-Long Cycle Life: Built with premium Grade A LiFePO4 materials, offering a phenomenal 4000-cycle lifespan. Excellent long-term value compared to standard cells.
- Ultra-Low IR (≤2mΩ): Maintains an internal resistance of just under 2mΩ. Minimizes heat generation during high-current charge/discharge, ensuring stability and safety.
- 15Ah True High Capacity: Guarantees a full 15Ah stable capacity, delivering excellent range for your electric devices.
- Flexible 2-Pack Option: Sold in 2-cell packs, ideal for replacing dual-battery devices or as high-quality sample units for testing before bulk procurement.

FAQ
Q: What does an IR of under 2mΩ mean?
A: For a 32140 cell, an internal resistance under 2mΩ is exceptional. It means the battery generates practically no heat during 45A high-current discharge. All electrical energy is converted into work, dramatically extending the cell's lifespan.
Q: Can 2 cells make a 7.4V pack?
A: No. This is a 3.2V LiFePO4 cell. 2 cells in series will create a 6.4V pack. If you need a 12V system, you need 4 cells in series. Please ensure your device voltage matches 3.2V multiples. Never mix them with 3.7V Li-ion batteries.
Q: Are the 2 cells from the same batch?
A: Yes, every 2-Pack is tested and matched from the same production batch to ensure consistency in IR, voltage, and capacity.
