48v battery pack with 48v 3Ah batteries. I used a 48v 5Ah battery pack that I bought off of Amazon. You can use any brand of
pack if you want to. If you want to use my battery pack, just make sure that it is rated at 48V and has a capacity of at least 5Ah. The voltage is not important as we will be using a DC-DC converter to drop the voltage down to 12V for the motor controller and lights.
Low voltage disconnect (LVD) – This is optional but recommended because it will prevent your batteries from being drained if you accidentally leave an accessory on or have a short somewhere in your system (for example, my LED strip lights stopped working after I installed them and I could not figure out why). A LVD should be placed between the power source (battery) and the loads (motor controller, lights, etc.). It must be rated for at least twice the continuous current draw of your system’s loads so make sure yours has enough capacity!
Battery temperature sensor – This is optional but recommended because it will allow your ESCs to automatically adjust their performance based on how warm or cold your batteries are getting during
Apply the Insulation
The most important step in the process is applying the insulation. Insulation is used to prevent short circuits and ground loops, which can damage the battery. Insulation also helps protect the battery from extreme weather and vibration.
The insulation should be applied before you connect all of the wires together. This will ensure that there are no stray wires or connections left exposed when you are done with the assembly process.
The insulation should be applied in a way that allows for easy access to all of your connections as well as any connectors or terminals on your battery. It also needs to be durable enough that it does not break off easily during normal use.
If you are using PVC pipe for your insulation, make sure that you have some kind of support structure in place before you begin applying insulation tape or other materials to it. Otherwise, it will fall apart when it is time to remove these items from your battery bank
Connect the Positive Side of Your Battery
If you are using a CTEK charger, connect the positive side of your battery first. The positive terminal has a red clamp on it, while the negative terminal has a black clamp.
Connect the Negative Side of Your Battery
Once you have connected the positive side of your battery, it is time to connect the negative side. The negative side of a car battery has a black clamp, while the positive side has a red clamp.
Make Sure Your Battery Is Fully Charged
Before disconnecting your charger from your car, make sure that it is fully charged by checking its charge indicator light. A fully charged battery will have no problem starting your engine when you need it to do so.
