With the release of the first of the new Tokyo Marui Evolt series, Deka provides a specialized guide on the precautions and steps necessary for installing a battery into the M4A1 Carbine Evolt electric gun. Because the Evolt series features a unique internal structure compared to previous models, the guide begins by emphasizing the importance of reading the manual and performing a proper "take down" of the upper receiver. Before starting, users must ensure the magazine is removed and the selector lever is set to the safety position to prevent any accidental discharge or mechanical issues during the process.

The technical core of the installation involves precise handling of the connectors and wiring. Once the buffer tube connector is retrieved, it must be aligned correctly with the battery before being connected. To prevent damage, the wiring should be kept straight and untwisted, then folded gently against the side of the battery. A key tip shared in the video is to rotate the battery 90 degrees during insertion to help it slide into the buffer tube more easily, allowing it to gradually return to its original angle as it is pushed into place.

Finally, the video details the correct placement of the battery cover, noting that the hole should face forward and the notch should face upward to accommodate the wiring within the bottom groove. As the battery is fully inserted, the user should feel no significant resistance; if the components do not sit flush or if there is resistance, it indicates that the cables may be pinched or the battery is misaligned. The guide concludes with a reminder to never force the parts together, as patience and careful alignment are essential to avoid breaking the equipment and to ensure the Evolt functions reliably.
