The lithium-ion 18650 two cell battery holder with switch combines three features engineers typically wire separately, a dual 18650 cell holder, a protective lid and an on/off switch in one compact plastic body. Two 18650 Li-Ion cells in series produce 7.4V nominal output, reaching approximately 8.4V at full charge. That 7.4V level suits requiring more than 5V but less than the 11.1V that a 3S holder produces. Unsoldered wire leads gives the full connector flexibility, crimp a JST, XT30 or solder directly to PCB pads.
The 18650 holder with on off switch integrated slide switch interrupts the output without requiring an external switch component wired into the circuit flip to off and the output disconnects while cells remain loaded in the holder. The protective cover clips over both cells, preventing them from dislodging during movement and handling in portable project. The switch holder 18650 suits 7.4V robot, portable instruments and field sensor enclosures. This holder is available on StemVolt and is working on 2S 18650 portable project.
