1 pcs battery box and 4pcs wheel,
2 pcs Epoxy board A,
2 pcs Epoxy board B,
2 pcs Epoxy board C,
16 pcs M6 * 14 hexagon Phillip screws.

Tool:
Electric screwdriver
10mm sleeve and PH3 cross screwdriver

Step 2. Cell Placing

1. As shown in "Figure 1", Paste EVA foam on the surface of the cell to separate cells.
2. As shown in "Figure 2", Put the cells into the case. Paste epoxy board B to separate cell from cell, and cells from front plate paste epoxy board C.
3. Fix the front plate with six M8 *20 hexagon Philips screws as shown in "Figure 4" Set the torque index of the electric screwdriver to 12nm. (Standard torque: 25nm) until the electric batch clicks.

Material:
16pcs cells, 18pcs cell foams，
2 pcs Epoxy board A,
1 pcs Epoxy board B,
2 pcs Epoxy board C,
6pcs M8* 20 hexagon Philips screws.

Tool:
Electric screwdriver,
13mm sleeve and PH4 cross screwdriver

Note:
Due to different manufacturers of the cell tolerance, according to the instructions after the foam is still loose, increase the foam filling.

Step 3. Top Bracket Installation

1. As shown in "Figure 1", Paste EVA foam on the bracket and align the hole position.
2. As shown in "Figure 2", Fix the top bracket with eight M5 * 8 hexagon Philips screws. Set the torque index of the electric screwdriver to “6”.(Standard torque:6nm) until the electric batch clicks.
3. Install the aluminum row, as shown in "Figure 3" to install the serial aluminum row on the pole.
4. Place gaskets, such as "Figure 4" the gaskets are placed on the aluminum bar; B+, B- poles do not put gaskets.

Material:
2 pcs top bracket EVA foams,
2 pcs top brackets,
