Making an RC Battery Pack - A Basic How-To
If you love RC, you recognize the significance of a battery pack. The kind of batteries you end up picking, how effectively your pack is assembled And exactly how proficiently you demand them are all vital areas to powering your RC car. Certain, You should purchase a battery pack pre-assembled, but It's also possible to Develop your personal and obtain the satisfaction of coming up with and powering your own car or truck.
The first thing you'll want to do is when you decide To place with each other a battery pack is what you are powering and just how much juice you require. You furthermore mght need to have to consider the following:
one. Look at the chassis of your respective automobile. The type of car or truck will not subject around the level of Room through which You need to maneuver. The batteries may well have to be oriented within a flat pack, a clustered pack or as each. It's also advisable to consider the distribution of pounds in your automobile - whether the battery fat will be distributed in a aspect to side or back to front method. Sometimes your chassis space for just a battery pack is just not adaptable, so pay attention to Those people constraints Before you begin.
2. Look at the motor powering your RC automobile. With regards to the electric power specifications, you can decide the amount of batteries or cells you would like. This is often also if you can choose the type of batteries you may use - if you want to maintain your NiMH batteries or upgrade to LiPo.
3. Determining your voltage can be a basic make any difference of addition. A regular cell voltage is 1.2v, so wired in a collection - 12 batteries will increase nearly fourteen.4v - which would electrical power an fourteen.four volt RC electric powered motor.
Future, You will need to gather your battery pack materials - so This is a sample browsing listing. Keep in mind, we are assuming we are creating a battery pack with fourteen.4v, as in the example over:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you may buy battery bars in bulk if you propose to construct multiple pack and preserve $)
o Wire: You'll want a greater excellent 12 gage using a high strand count. This type of wire, Using these attributes are going to be much more adaptable which is good and becoming a lot more economical for energy transmission.
o 80-one hundred Watt Soldering Gun. You'll be wanting a gun because you is usually more specific and faster - this is important as a result of warmth sensitivity of batteries. The a lot quicker and even more unique you'll be able to be, the less likely you'll be to damage the battery.
o sixty/40 Solder. That is greater good quality - also vital for swift and exact get the job done and keeping away from battery damage.
o Flux. It is a chemical cleansing agent that removes oxidation from metallic to aid soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive is going to be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries thoroughly and aid a tidy battery pack. The batteries find yourself generally on the lookout like twine Wooden - tidily bundled.
o Soldering "Aiding Fingers" - optional. These gadgets assist you to hold points set up When you solder.
o Another optional timesaver is to secure a "Supporting Palms" accent for the soldering station.
o Multi Meter. You need a excellent multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools will let you handle, strip and effectively Lower your 12 gage wire.
o The ultimate ingredient will be the shrink wrap that can go across the full assembly and retain it tidy. You'll also need a warmth gun to heat and shrink the wrap.
So, you have recognized tips on how to orient your batteries and the amount of you'll need - now you receive to work on assembly. For this example, we are assembling 12 battery cells - six down one particular facet and six down one other.
When you recognize in which the batteries are going in relation in your chassis and how they're going to generally be laid out, you may start out. For this instance, for instance we're undertaking 6 down a person aspect and six down the opposite facet.
Just to be certain we are on precisely the same site, the last word intention here is to generally be working wire through the good terminal of one's initially battery on the constructive terminal on the electric RC motor then running a wire through the unfavorable terminal on the final battery within your pack into the constructive terminal of one's other battery pack, thereby developing a concluded circuit.
This imply you need to have adequate wire to reach from your positive terminal within your 1st battery to that terminal and Furthermore with the damaging to finish the circuit with your other battery pack so bear that in mind.
Orientation. Align your very first cell to ensure constructive is pointing "upwards" and adverse is pointing "downwards" then reverse another battery so It can be opposite on down the road. If you bought the battery assembly jig, This really is whenever you'd use it to align your cells and keep them set up.
Adhere. Stick every one of the batteries together with your quickly drying adhesive to They can be so as and aligned correctly.
Flux. Use your flux now on the link factors.
Connection - Make use of your battery bars to attach your cells. You'll have to heat up your soldering gun and heat up the battery bar. Utilizing the bar guards the battery and in the event the flux begins to bubble, you make use of your utilization of solder. The objective is not to heat the battery alone. Heating the battery is not simply counterproductive, since if you destruction the battery it is not going to do the job, but will also harmful as the cell may possibly explode if Automated Guided Vehicles (AGV) Battery overheated.
You'll be wanting to complete the exact same measures for that remaining battery connections. You are connecting the negative into the good time and again all over again. You can expect to then be ready to attach wiring in your battery pack.
The wires should be pre-tinned which necessarily mean you'll want to strip off a quarter inch with the protecting plastic wiring sheath, use the flux to wash them - implement the flux liberally - heat your solder gun after which you can warmth the wire and flow the solder into the wire until eventually totally saturated. You can expect to also want solder about the batteries Hence the solder will act as the connector Along with the battery.
Once the two, 6 cell battery packs are full, you'll want to make use of the shrink wrap to secure them - and you'll have your finish battery pack! Now you'll be able to ability and fly your RC helicopter, plane, boat, car or truck with no complications!
