12-pack 18500 Li-ion cells for custom packs

These twelve 4/3 A lithium-ion cells deliver 3.7 volts nominal and 1400 mAh capacity each. They arrive with solder tabs on both ends for direct integration into battery packs. The cylindrical 18500 format measures 50.3 mm by 18.3 mm and weighs 34 g per cell. They suit builders assembling replacement packs for torches, instruments or legacy equipment.

Tabbed terminals demand soldering skill

The exposed tabs require spot-welding or careful soldering; they are not spring-contact ready. Maximum charge current is 1.5 A and maximum discharge is 2.6 A, so any pack design must include a matching protection board. Without proper circuitry the cells can overheat or vent. Users must understand lithium-ion handling before assembly.

Replaces loose 18650 cells when space is tighter

The 18500 length is shorter than an 18650, fitting compartments that cannot accept the longer cell. Capacity sits at 1400 mAh, lower than most 18650 alternatives, so the swap only makes sense when physical length is the limiting factor. It is not suited for high-drain devices needing above 2.6 A continuous draw.

Questions about this item

Should I pick the 1400 mAh or 1500 mAh rating when choosing this 12-pack?

The supplier title lists 1400 mAh while the detailed specs show 1500 mAh; both refer to the same 18500 cells, so expect roughly 1500 mAh typical capacity per battery.

What does the 3.7 V nominal voltage mean once the cells are inside my device?

Each 18500 cell delivers 3.7 V nominal; a single cell powers 3.7 V gear, while multiple cells in series raise the pack voltage in 3.7 V steps.

How do the solder tabs affect the way I can connect these 18500 cells?

Tabs on both ends let you spot-weld or solder the 18500 cells into custom packs without needing spring contacts or holders.
