FAQ
Q: What are the exact dimensions of this 32140 battery?
A: The cell label says 32140, but the actual measured size is approximately 32mm × 140mm. Due to mold tolerances in different batches, there might be a ±1mm variation. Please reserve some physical clearance in your custom battery compartments.
Q: What size battery pack can I build with 120pcs?
A: 4 cells in series make a 12.8V 15Ah pack; 16 cells in series make a 51.2V 15Ah pack (48V system). 120 cells are more than enough to build 10x 12.8V packs, making it ideal for bulk purchasing by battery manufacturers.
Q: What BMS do I need for this 3C discharge cell?
A: Since each cell has a max continuous discharge of 45A, you must use a dedicated LiFePO4 BMS with high-power MOSFETs. We strongly recommend a BMS with a balancing function rated at 45A or higher.
