The 4 Slot 18650 lithium battery holder mounts four 18650 Li-Ion cells in series, combining their 3.7V nominal voltages into 14.8V nominal output the standard voltage of a 4S Li-Ion configuration. Four cells in series reach approximately 16.8V at full charge with each cell at 4.2V. This removable holder format gives projects 4S voltage without requiring spot welding or a sealed welded pack, cells load individually, charge separately and replace individually when capacity degrades.
The 18650 4 slot holder high quality body uses spring contacts at each cell terminal to retain all four cells securely during operation. Open wire leads connect to the project circuit by direct soldering, JST or XT30 connector crimping or terminal block attachment. The 18650 4 battery holder 14.8V output requiring higher voltage than 3S 11.1V provides, 14.8V drives higher-voltage motor drivers, LED driver modules and servo arrays with greater efficiency at the same current draw. Available on StemVolt. This holder is working on 4S 18650 portable power and removable cell pack.
