About this product
A single-cell holder for one 18650 lithium-ion battery, with a nominal voltage of approximately 3.7 V and gold-plated SMD pads for PCB mounting. It has four pads underneath, so it can be wired in different configurations to reach the voltage a project requires. Use protection and charging circuitry suited to lithium-ion cells.

Frequently asked questions
What voltage does one cell give?
About 3.7 V nominal. A fully charged Li-ion cell is about 4.2 V and the voltage falls as it discharges, so protection is needed to avoid over-discharge.
Can I connect several cells in series for higher voltage?
The four pads allow different wiring, but series or parallel lithium cell configurations need a battery management system to balance and protect the cells.
