Li-Ion case for MAKITA 6281DWPE 14.4V

This is a custom build for replacing original Ni-Cad battery case with a bigger enclosure that can accommodate eight 18650 Li-Ion cells, arranged in a 4S2P formation, using standard interlocking plastic spacers. The original springclips and top part will fit perfectly. Two holes will be cut for ballance cable connector and low voltage monitor on/off switch.
WARNING! Do not use original Ni-Cad charger for charging Li-Ion cells!
