18650 3.2V 1500mAh LiFePO4 Lithium battery from SIMPOWER

The 18650 3.2V 1500mAh LiFePO4 Lithium battery from SIMPOWER is a high-grade Lithium Iron Phosphate (LiFePO4) cell. Lithium Iron Phosphate can be a great choice in battery pack design due to its convenient cell voltage, high energy density, cycle life and most importantly due to it being one of the safest Lithium technologies available.

The 18650 LiFePO4 Lithium battery has a nominal voltage of 3.2V and a typical capacity of 1.5Ah.

Standard charge currents for a charge time of approximately 6 hours are as follows: IFR18650 18650 LiFePO4 Lithium Iron Phosphate Battery

Constant Current 0.2C5A

Constant Voltage 3.65V 0.02C5A cut-off

Fast charge currents for a charge time of approximately 2.5 hours are as follows:

Constant Current 1C5A

Constant Voltage 3.65V 0.01C5A cut-off

Use caution when working with and using Lithium Iron Phosphate batteries as they are very sensitive to charging characteristics and may explode, burn, or cause a fire if misused or mishandled. Always charge in or on a fire-proof surface. Never leave batteries charging unattended. Buyer is responsible for any damage or injury caused by misuse or mishandling lithium ion batteries and chargers. No express or implied guarantee of compatibility with any device can be made.

Charge only with a smart charger designed for this specific type of lithium battery. Do not mix and match old and new, used and unused batteries.

  • Misuse or mishandling of lithium ion batteries can pose a SERIOUS RISK of personal injury, property damage, or death
  • ONLY use with proper protection circuitry, “PCM” or “BMS”
  • ONLY use within manufacturer specification
  • DO NOT store loose in pocket, purse, etc. – always use a protective case
  • KEEP AWAY from metal objects to prevent short circuiting
  • DO NOT short circuit
  • DO NOT use if wrapper or insulator is damaged or torn
  • DO NOT overcharge or over-discharge
  • DO NOT use if damaged in any way
  • DO NOT modify, disassemble, puncture, cut, crush, or incinerate
  • DO NOT expose to liquids or high temperatures
  • DO NOT solder
