Building an RC Battery Pack - A Basic How-To
If you like RC, you already know the necessity of a battery pack. The kind of batteries you end up picking, how perfectly your pack is assembled and how successfully you demand them are all significant features to powering your RC car or truck. Certain, you can buy a battery pack pre-assembled, but You may as well Construct your own personal and acquire the fulfillment of creating and powering your personal vehicle.
The first thing you should do is when you decide To place collectively a battery pack is what you are powering and just how much juice you will need. In addition, you have to have to think about the following:
one. Look at the chassis of the car. The type of car won't matter as much as the level of Room where You should maneuver. The batteries may should be oriented in a flat pack, a clustered pack or as the two. It's also advisable to take into consideration the distribution of pounds as part of your automobile - if the battery excess weight is going to be distributed within a side to aspect or back again to front way. Sometimes your chassis Area for the battery pack will not be adaptable, so be aware of These constraints before you start.
2. Consider the motor powering your RC vehicle. Depending on the electrical power prerequisites, you can ascertain the amount of batteries or cells you'll need. This is also after you can decide the kind of batteries you will use - if you wish to keep your NiMH batteries or update to LiPo.
3. Determining your voltage is really a uncomplicated subject of addition. A regular cell voltage is one.2v, so wired in a very series - twelve batteries will incorporate up to 14.4v - which would electrical power an 14.4 volt RC electric powered motor.
Up coming, you'll need to collect your battery pack provides - so This is a sample procuring record. Bear in mind, we are assuming we're creating a battery pack with 14.4v, as in the example over:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you can get battery bars in bulk if you intend to develop multiple pack and preserve $)
o Wire: You will need a greater high quality 12 gage which has a higher strand count. This sort of wire, Using these traits are going to be a lot more adaptable which is good together with currently being a lot more economical for ability transmission.
o 80-a hundred Watt Soldering Gun. You'll be wanting a gun simply because you is usually far more exact and more rapidly - this is necessary due to the heat sensitivity of batteries. The speedier and a lot more particular you could be, the more unlikely you'll be to break the battery.
o sixty/forty Solder. That is greater high-quality - also crucial for brief and correct operate and keeping away from battery destruction.
o Flux. This is a chemical cleaning agent that eliminates oxidation from steel to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying adhesive will likely be accustomed to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries adequately and facilitate a tidy battery pack. The batteries finish up fundamentally looking like twine wood - tidily bundled.
o Soldering "Assisting Arms" - optional. These equipment help you hold points set up Whilst you solder.
o A further optional timesaver is to get a "Helping Palms" accessory for your soldering station.
o Multi Meter. You'll need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will let you handle, strip and adequately Slash your 12 gage wire.
o The final part is the shrink wrap that will go across the entire assembly and preserve it tidy. You are going to also require a heat gun to heat and shrink the wrap.
So, you have discovered ways to orient your batteries and the number of you need - now you obtain to operate on assembly. For this instance, we're assembling twelve battery cells - 6 down a person facet and 6 down the other.
After you establish the place the batteries are going in relation in your chassis And the way they are going to get laid out, you could begin. For this example, as an instance we are performing six down just one facet and 6 down the other aspect.
Just to verify we are on the exact same site, the ultimate objective here is to get managing wire with the constructive terminal of your to start with battery to the constructive terminal on the electrical RC motor and afterwards running a wire from the destructive terminal on the last battery inside your pack to the good terminal within your other battery pack, thereby creating a accomplished circuit.
This necessarily mean you might want to have enough wire to succeed in with the beneficial terminal of one's very first battery to that terminal and likewise within the negative to complete the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your to start with cell to ensure positive is pointing "upwards" and adverse is pointing "downwards" then reverse the subsequent battery so It is really reverse on down the road. If you purchased the battery assembly jig, This really is if you'd utilize it to align your cells and keep them in position.
Adhere. Adhere the many batteries together with your rapid drying adhesive to These are as a way and aligned properly.
Flux. Make use of your flux now within the connection details.
Connection - Make use of your battery bars to attach your cells. You'll need to warmth up your soldering gun and warmth up the battery bar. Using the bar protects the battery and in the event the flux begins to bubble, you hire your utilization of solder. The purpose is not to warmth the battery itself. Heating the battery is not only counterproductive, considering that should you damage the battery it is not going to operate, but in addition harmful because the mobile may possibly explode if overheated.
You'll want to complete the same ways to the remaining battery connections. You might be connecting the detrimental for the optimistic over and over once again. You will then be All set to connect wiring in your battery pack.
The wires should be pre-tinned which necessarily mean you'll want to strip off a quarter inch on the protecting plastic wiring sheath, utilize the flux to scrub them - utilize the flux liberally - Automated Guided Vehicles (AGV) Battery heat your solder gun and then heat the wire and flow the solder to the wire until totally saturated. You can also want solder on the batteries And so the solder will act because the connector While using the battery.
As soon as the two, 6 cell battery packs are complete, you will need to utilize the shrink wrap to safe them - and you will have your comprehensive battery pack! Now you can electric power and fly your RC helicopter, airplane, boat, vehicle or truck without troubles!
