Constructing an RC Battery Pack - A Standard How-To
If you love RC, you are aware of the necessity of a battery pack. The kind of batteries you choose, how perfectly your pack is assembled And exactly how proficiently you cost them are all vital aspects to powering your RC car or truck. Confident, You should purchase a battery pack pre-assembled, but you can also Create your very own and get the satisfaction of creating and powering your own private car or truck.
The very first thing you need to do is when you choose To place together a battery pack is what you are powering and how much juice you would like. In addition, you want to consider the next:
1. Consider the chassis within your automobile. The sort of motor vehicle will not make any difference approximately the quantity of Place wherein You must maneuver. The batteries might should be oriented inside a flat pack, a clustered pack or as equally. It's also advisable to contemplate the distribution of bodyweight with your motor vehicle - whether the battery body weight will likely be distributed inside of a aspect to aspect or back again to front way. In some cases your chassis space for your battery pack is just not adaptable, so know about These constraints before you start.
two. Think about the motor powering your RC vehicle. According to the energy demands, you'll decide the quantity of batteries or cells you will need. This is certainly also whenever you can determine the sort of batteries you will use - if you need to maintain your NiMH batteries or improve to LiPo.
3. Deciding your voltage can be a basic make any difference of addition. A typical mobile voltage is 1.2v, so wired in a collection - 12 batteries will incorporate as much as 14.4v - which would ability an 14.four volt RC electrical motor.
Next, You'll have to gather your battery pack supplies - so This is a sample shopping list. Recall, we're assuming we're developing a battery pack with fourteen.4v, as in the example above:
o 12 Batteries or Battery Cells
o twelve Battery Bars (it is possible to get battery bars in bulk if you plan to develop multiple pack and help save $)
o Wire: You'll want a better high-quality twelve gage using a high strand rely. Such a wire, with these attributes is going to be much more versatile which is good and getting far more successful for ability transmission.
o eighty-one hundred Watt Soldering Gun. You will need a gun because you is usually much more precise and quicker - this is important as a result of warmth sensitivity of batteries. The faster and more precise you'll be able to be, the more unlikely You will be to damage the battery.
o sixty/forty Solder. This is greater top quality - also significant for fast and correct do the job and averting battery problems.
o Flux. This is the chemical cleaning agent that eliminates oxidation from steel to aid soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive will probably be used to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries properly and facilitate a tidy battery pack. The batteries turn out essentially seeking like twine wood - tidily bundled.
o Soldering "Aiding Arms" - optional. These equipment allow you to hold points set up As you solder.
o Yet another optional timesaver is to get a "Assisting Hands" accessory for the soldering station.
o Multi Meter. You'll need a great multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will assist you to take care of, strip and correctly Slice your 12 gage wire.
o The final part is the shrink wrap which will go throughout the full assembly and hold it tidy. You'll also need a warmth gun to warmth and shrink the wrap.
So, you have discovered ways to orient your batteries and what number of you require - now you have to work on assembly. For this instance, we are assembling 12 battery cells - 6 down one aspect and 6 down the opposite.
As you establish wherever the batteries are likely in relation towards your chassis And the way they're going to generally be laid out, it is possible to commence. For this example, as an instance we're accomplishing six down a person facet and 6 down the opposite facet.
Just to be certain we're on the same site, the ultimate objective here is to be jogging wire in the constructive terminal of the initially battery into the favourable terminal on the electrical RC motor after which working a wire with the detrimental terminal Automated Guided Vehicles (AGV) Battery on the final battery in the pack for the optimistic terminal of your respective other battery pack, thus developing a completed circuit.
This necessarily mean you should have sufficient wire to succeed in from the constructive terminal within your 1st battery to that terminal and Also from the detrimental to accomplish the circuit with your other battery pack so bear that in your mind.
Orientation. Align your first cell making sure that beneficial is pointing "upwards" and destructive is pointing "downwards" then reverse another battery so It is really reverse on down the line. If you bought the battery assembly jig, This is certainly when you'd utilize it to align your cells and keep them set up.
Adhere. Stick all the batteries together with your quick drying adhesive to they are so as and aligned properly.
Flux. Make use of your flux now within the connection points.
Link - Use your battery bars to connect your cells. You'll have to heat up your soldering gun and warmth up the battery bar. Using the bar shields the battery and when the flux begins to bubble, you hire your use of solder. The aim is to NOT heat the battery alone. Heating the battery is not simply counterproductive, since in the event you hurt the battery it will never get the job done, but will also perilous as the cell could possibly explode if overheated.
You'll be wanting to accomplish exactly the same steps for your remaining battery connections. You will be connecting the damaging on the constructive over and over yet again. You may then be ready to attach wiring to your battery pack.
The wires should be pre-tinned which mean you need to strip off 1 / 4 inch of your protective plastic wiring sheath, utilize the flux to wash them - use the flux liberally - warmth your solder gun and then heat the wire and flow the solder in the wire till extensively saturated. You can expect to also want solder about the batteries And so the solder will act since the connector While using the battery.
When the two, 6 mobile battery packs are total, you'll want to utilize the shrink wrap to safe them - and you will have your complete battery pack! Now you can power and fly your RC helicopter, airplane, boat, car or truck or truck without having complications!
