FAQ
Q: What are the exact dimensions of this 32140 battery?
A: While labeled as 32140, the actual physical dimensions are approximately 33.4mm (Dia) × 140.3mm (Height). Please double-check your battery compartment size. If your compartment diameter is smaller than 34mm, it will not fit.
Q: Can I buy 100pcs to build a 48V battery pack?
A: Absolutely. 4 in series makes 12.8V, 16 in series makes 51.2V. 100pcs is perfect for this. However, you must use a dedicated high-current LiFePO4 BMS with a balancing function and perform strict cell matching before assembly.
Q: How are the 100pcs shipped?
A: They are shipped in original factory bulk cardboard boxes with anti-static/anti-shock protection. They are not individually retail-packaged, ideal for direct use in production lines or assembly workshops.
