Losi LOSB0105BD - Manual (Page 10)

Battery Pack(s):
To install the battery pack remove the battery hold-down strap by removing the clip from the front mounting boss, and then,
while lifting the strap, pulling forward in one motion.
After you have inserted the fully-charged battery pack reinstall the battery hold-down strap.
Notice that the battery hold-down has a flat side while the other side has strengthening ribs; the rib side should be facing
down to the battery.
Insert on an angle into the rear support, and then down on the front pin and secure it with the previously removed clip.
