Product description
This battery holder connects two 18650 lithium-ion cells in series, providing a nominal voltage of 7.4 V. The two cells are housed in a compact plastic casing and sit on sturdy spring contacts that ensure reliable current flow. The protection circuit includes monitoring for overcharging and deep discharge, significantly extending the cells' service life.
The holder is connected via two solderable wires, offering maximum flexibility when integrating it into projects. Whether connected directly to the load or through a charge controller and voltage regulator, the connections allow for numerous circuit configurations. The protection circuit detects critical operating conditions and interrupts the circuit as needed.
Applications include portable electronics projects such as wireless sensors, mobile LED systems, or small motor controllers. The holder is also suitable as a power source for portable experimental equipment or for operating microcontroller boards over extended periods. Thanks to its compact dimensions, it fits into many housings and mounting arrangements.
A suitable charger that charges 18650 cells with overcharge protection is required for use. The cells themselves are not included and must be purchased separately. Maximum discharge currents depend on the cell type used and should be checked before assembly.
Safety information
Lithium-ion cells must not be short-circuited or damaged in order to prevent the risk of fire and explosion. This battery holder is intended exclusively for building prototypes and for testing and development purposes and is not suitable for installation in the household power circuit. Consult a qualified electrician if you have questions about sizing or protecting the system before commissioning it.
