# Chapter 1: Battery Board Assembly
In this chapter, the user will learn the proper steps to assemble an Electrical Power System (EPS) board. The steps can be followed again to create an optional ballast to add weight to the satellite, or while not recommended, additional power to the satellite.
In this chapter, the user will learn the proper steps to assemble an Electrical Power System (EPS) board. **These steps can be followed again to create an optional ballast. These instructions are included below.**

!!!Warning
***Before continuing:** it is important to note that gloves should be worn when soldering and it should be done in a well-ventilated area to avoid the harmful fumes.*</span>


## Soldering the Relay
1. Align the relay onto the white box by the top left corner of the battery board. Make sure the dot on the top side of the relay is closest to the slot hole as seen as figure 1.1
![Figure 1-1](images/8-1.jpg)

**1.** Align the relay onto the white outline by the top left corner of the battery board.

2. The Relay on the EPS board has through hole connections that will need to be soldered to on the bottom side as seen in Figure 1.2
![Figure 1-2](images/RELAY.png)
*<p align="center">Figure 1.2 </p>*
**2.** On the top side of the relay there is a dot that must be aligned to the slot hole as seen in Figure 1.1

*<p align="center">**Figure 1.1: Flight Controller Board** </p>*

**3.** On the bottom side of the EPS board there are through connections where the Relay must be sodered as seen in Figure 1.2

3. The sodering should not be flush to the board,rather there should be enough so that the relay's legs bend and it will be allowed to lay on it's side. This can be seen in figure 1.3 and is also stated on the board.

**4.** The sodering **should not** be flush to the board, rather there should be room for the relay's legs bend which will allow it to lay on it's side. This is stated on the board and is shown figure 1.3

## **OPTIONAL**: Ballast Board creation
<div class="result" markdown>
1. Follow all of the prior steps to create a secondary EPS
2. If additional power is desired for the satellite, a wire can be soldered to the Pack+ Test point between both boards, and a wire can be soldered to the B- Test point between both boards.



**1.** Follow all of the prior steps to create a secondary EPS

!!!WARNING
It is not recommended that additional power be added to this satellite
**2.** If additional power is desired for the satellite, a wire can be soldered to the Pack+ Test point between both boards, and a wire can be soldered to the B- Test point between both boards.

## Check your work
If all steps were followed correctly, the EPS should appear as it does in Figure 1.6. (notwe that this should show both the front and back)
</div>
If all steps were followed correctly, the EPS should appear as it does in Figure 1.7.

!!!Note
This does not include the secondary EPS or additional power modifications stated above

## Make 4-6 Jumped 2 Position Pico-Lock Cable Assemblies
<div class="result" markdown>
1. 300mm 5 position Pico-Lock cable assemblies have been included in the kit as well as 2 position connectors. The 100mm assemblies will be used for connecting the solar boards to the EPS, and the 300mm assemblies will be used to create all the needed 2 position Pico-Lock assemblies. The first step will require taking a cable out of the 300mm 5 position assembly. To start, take the needle nose tweezers and lift the locking mechanism as seen in Figure 2.1 and pull the cable from each connector housing.
2. Take the freed cable and insert both ends into one 2 position connector housing as seen in Figure 2.2

The steps are similar for creating the non-jumped cables required for the burn wire and direct charging ports. The primary difference is that two cables will be required as well as 2 connector housings. The non-Jumped assemblies can be seen in Figure 2.3

!!! warning
Test all sensors for full functionality prior to solar cell installation (see Chapter 7 that identifies the proper test to complete for the solar boards). If sensors are faulty and need to be reflowed or removed with a heat gun, the cells will be damaged in the process.

!!! Note
The Motor Driver Modification step is completely optional as the magnetorquers can be deactivated in software. Only one X Magnetorquer and one perpendicular Y Magnetorquer need to remain active in order to detumble the satellite effectively. The Z- Solar board should let the magnetorquer coil remain active as this is the only coil on the Z faces.
