Description

32140 15Ah Battery Specification Overview

The 15Ah 32140 is a lithium iron phosphate (LiFePO4/LFP) battery in the 32140 cylindrical format (32mm diameter x 140mm height). It’s designed for high-capacity, high-cycle-life applications, particularly in energy storage and electric vehicles. Here’s a detailed breakdown:

Key Specifications

• Model: CNAE-32140

• Chemistry: LiFePO4 (LFP)

• Nominal Capacity: 15Ah (15000mAh)

• Nominal Voltage: 3.2V

• Charge Voltage: 3.65V (max)

• Discharge Cut-off: 2.5V

• Max Continuous Discharge: 30A (2C)

• Peak Discharge (pulse): 60A (4C, ≤3 sec)

• Standard Charge Current: 7.5A (0.5C)

• Fast Charge Possible: Up to 15A (1C)

• Cycle Life: 2000+ cycles (to 80% capacity)

• Dimensions: 32mm × 140mm

• Weight: ~450g (varies by manufacturer)

• Operating Temp: ◦ Charge: 0°C to 45°C ◦ Discharge: -20°C to 60°C

Key Features

High Capacity – 15Ah is substantial for a single cell, ideal for energy storage.

Long Cycle Life – 2500+ cycles (far exceeding standard Li-ion/NMC batteries).

Safety – LiFePO4 chemistry is non-flammable and stable under abuse.

High Discharge Capability – 30A continuous (suitable for power tools, small EVs).

Common Applications

• Solar energy storage systems (home/grid storage)

• Electric bikes/scooters (as part of a battery pack)

• Power tools (replacing lead-acid or NMC packs)

• Marine/RV power systems • Backup power stations

Safety & Handling

No protection circuit needed (LiFePO4 is inherently safer than NMC/Li-ion). Use a LiFePO4-compatible charger (3.65V max, not 4.2V Li-ion chargers). Avoid short-circuiting – Can still deliver dangerous current. Storage: Store at ~50% charge in a cool, dry place.

WARNING:

Do NOT expose the battery to water

Do NOT expose the battery to fire & high temperature

Do NOT short circuit, crush or disassemble

Only use LiFePO4 charger Storage at 50% capacity, recharge every 3 months. The storage area should be clean, cool, dry and ventilated.
