Constructing an RC Battery Pack - A Basic How-To
If you like RC, you know the value of a battery pack. The sort of batteries you choose, how perfectly your pack is assembled And just how proficiently you charge them are all vital factors to powering your RC auto. Certain, You should buy a battery pack pre-assembled, but It's also possible to Establish your own and obtain the gratification of building and powering your own auto.
The very first thing you'll want to do is when you decide to put together a battery pack is what you're powering and exactly how much juice you'll need. In addition, you will need to consider the subsequent:
one. Consider the chassis of the automobile. The type of motor vehicle isn't going to make a difference just as much as the quantity of space by which You should maneuver. The batteries may well have to be oriented in the flat pack, a clustered pack or as each. It's also wise to think about the distribution of body weight in the motor vehicle - if the battery pounds will probably be distributed inside of a facet to aspect or again to front fashion. In some instances your chassis Area for the battery pack is not adaptable, so pay attention to People constraints before you start.
2. Consider the motor powering your RC car or truck. Depending on the ability demands, you'll determine how many batteries or cells you may need. This really is also after you can come to a decision the kind of batteries you can expect to use - if you would like maintain your NiMH batteries or upgrade to LiPo.
three. Analyzing your voltage can be a uncomplicated subject of addition. A normal mobile voltage is 1.2v, so wired within a collection - twelve batteries will include as much as 14.4v - which might electricity an fourteen.4 volt RC electric motor.
Up coming, You will need to collect your battery pack materials - so here's a sample browsing list. Keep in mind, we are assuming we are creating a battery pack with 14.4v, as in the example over:
o twelve Batteries or Battery Cells
o twelve Battery Bars (you may buy battery bars in bulk if you intend to create multiple pack and conserve $)
o Wire: You'll be wanting a greater high-quality twelve gage which has a higher strand count. This kind of wire, with these features is going to be additional adaptable which is good as well as remaining much more economical for electric power transmission.
o eighty-a hundred Watt Soldering Gun. You will need a gun because you might be more exact and faster - this is necessary due to warmth sensitivity of batteries. The more quickly plus much more particular you are able to be, the not as likely you'll be to wreck the battery.
o sixty/forty Solder. This is certainly higher good quality - also crucial for rapid and exact get the job done and staying away from battery injury.
o Flux. That is a chemical cleansing agent that eliminates oxidation from steel to aid soldering. You can utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive are going to be used to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries thoroughly and aid a tidy battery pack. The batteries finish up fundamentally searching like twine Wooden - tidily bundled.
o Soldering "Aiding Arms" - optional. These units assist you to keep points in place As you solder.
o Yet another optional timesaver is to obtain a "Aiding Arms" accent to your soldering station.
o Multi Meter. You will need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will allow you to cope with, strip and thoroughly Slice your twelve gage wire.
o The final component would be the shrink wrap which will go within the overall assembly and maintain it tidy. You will also need a warmth gun to heat and shrink the wrap.
So, you've recognized how to orient your batteries and the quantity of you would like - now you obtain to work on assembly. For this instance, we're assembling twelve battery cells - 6 down 1 facet and 6 down the other.
Once you recognize in which the batteries are likely in relation to the chassis And exactly how they're going to generally be laid out, you'll be able to start out. For this example, as an instance we're performing 6 down one side and six down the opposite side.
Just to ensure we are on precisely the same web site, the last word aim Here's being functioning wire through the favourable terminal within your to start with battery on the constructive terminal on the electrical RC motor and afterwards operating a wire in the unfavorable terminal on Automated Guided Vehicles (AGV) Battery the final battery with your pack to your favourable terminal of your respective other battery pack, thereby developing a concluded circuit.
This necessarily mean you might want to have sufficient wire to achieve in the favourable terminal within your initial battery to that terminal and Furthermore through the unfavorable to complete the circuit with all your other battery pack so bear that in your mind.
Orientation. Align your first mobile so that good is pointing "upwards" and detrimental is pointing "downwards" and afterwards reverse the subsequent battery so It really is opposite on down the line. If you bought the battery assembly jig, This really is any time you'd utilize it to align your cells and hold them set up.
Adhere. Stick each of the batteries along with your quick drying adhesive to They are really if you want and aligned effectively.
Flux. Use your flux now to the connection details.
Link - Make use of your battery bars to connect your cells. You'll have to heat up your soldering gun and heat up the battery bar. Utilizing the bar shields the battery and in the event the flux begins to bubble, you use your utilization of solder. The objective is to NOT heat the battery by itself. Heating the battery is not only counterproductive, due to the fact for those who harm the battery it will not work, but also harmful as the mobile may possibly explode if overheated.
You'll want to complete exactly the same methods to the remaining battery connections. You happen to be connecting the negative to the optimistic over and over once more. You may then be Completely ready to connect wiring for your battery pack.
The wires need to be pre-tinned which necessarily mean you might want to strip off 1 / 4 inch in the protecting plastic wiring sheath, make use of the flux to wash them - use the flux liberally - warmth your solder gun and afterwards warmth the wire and circulation the solder in to the wire right until comprehensively saturated. You can expect to also want solder within the batteries And so the solder will act since the connector With all the battery.
As soon as the two, six mobile battery packs are entire, you'll want to employ the shrink wrap to secure them - and you'll have your finish battery pack! Now you'll be able to power and fly your RC helicopter, plane, boat, car or truck without having problems!
