DUSLAN 8-Pack 18500 3.2V 800mAh LiFePO4 standard battery

Eight-cell LiFePO4 pack for 18500 devices

This eight-pack supplies 18500 cells with a nominal 3.2 V and 800 mAh capacity using lithium iron phosphate chemistry. Each cell measures 50 mm long by 18.1 mm in diameter and weighs 31.2 g. The pack suits equipment designed for the 18500 form factor that requires stable voltage and long cycle life.

LiFePO4 voltage and current limits

The lithium phosphate chemistry delivers a fixed 3.2 V nominal output rather than the higher voltage of lithium-ion alternatives, so devices must accept this lower potential. Continuous charge and discharge currents are capped at 0.8 A per cell, restricting use to low-drain applications. Energy density reaches 82.05 Wh/kg, and the cells tolerate up to 2000 charge cycles with no memory effect.

Replaces higher-capacity 18500 cells when cycle

These 800 mAh cells substitute for 1000 mAh, 900 mAh, 850 mAh, 750 mAh and 600 mAh variants in the same 18500 size. The trade-off is lower single-charge runtime in exchange for up to 2000 cycles and a stable 3.2 V profile. The jump is worthwhile for gear that prioritises longevity and consistent voltage over maximum capacity per charge.
