How To Make a Battlebot Battery Pack

Battlebots require a power source to enable their motors to run. The motors provide mobility and functionality to different parts of the battlebot. You can make your own battery pack for your battlebot and integrate it in your battlebot’s design.

1. Determine the voltage.

Before you begin to make a battery pack you must take a closer look at your battlebot’s design. You have to make sure you know how much voltage can run through the battlebot’s electronic system. You may put in too much voltage and risk frying your electrical components or put in a low voltage that will make your battlebot run slower. Determine how many motors are used to make the battlebot function. There are battlebots that use two motors, one for each side. And there are those that use more than two to control various functions on the battlebot.

Generally, the rules permit up to 48 volts of power on a battlebot to enter the combat zone. If you have determined that your battlebot can take on 48 volts of power, then the next step is to figure out what types of batteries to use and how they will be divided.

2. Plan voltage design.

There are different types of batteries with different amounts of voltage. How you divide the voltage will depend on how you want to design your battery pack for the battlebot. You can pack your batteries any way you like and you can design a battery case to hold them all securely in place. There will be a few considerations however, like if the battery pack design will affect the battlebots movements. It might hinder certain parts from moving freely. So take a look at your battlebot’s structural design and base the battery pack arrangement on that. Most battery packs on battlebots are arranged in rows so you can consider this method. You can create your own arrangement to adapt to your battlebot’s design. Now that you know how the battery pack will be positioned on the battlebot you can take down the dimensions. Use the dimensions to determine how to divide your batteries. You can either use NiCad, NiMh or lead acid batteries. The NiMh and NiCad batteries have about 1.2 volts while the lead acid batteries have 2 volts.

3. Assemble the battery pack.

Make the battery casing with metal or aluminium materials and put in battery holders so the batteries will be fixed in its position. Place the batteries inside the casing according to the arrangement you decided on. Join the batteries together either by soldering them together or solder contact wires to each of the positive and negative ends. Use shrink tubing to keep the batteries and connections intact.

The objective here is to provide adequate power to the battlebot and to hold the batteries secure while in combat.
