Building an RC Battery Pack - A Basic How-To
If you love RC, you already know the necessity of a battery pack. The sort of batteries you choose, how nicely your pack is assembled And just how successfully you charge them are all important factors to powering your RC automobile. Guaranteed, you can buy a battery pack pre-assembled, but It's also possible to Make your own private and have the gratification of planning and powering your individual auto.
The very first thing you'll want to do is when you select to put jointly a battery pack is what you're powering and just how much juice you'll need. Additionally you require to think about the subsequent:
one. Think about the chassis of one's car or truck. The sort of vehicle will not issue just as much as the quantity of space where You must maneuver. The batteries could have to be oriented in a very flat pack, a clustered pack or as both equally. It's also advisable to consider the distribution of fat within your car - whether the battery weight is going to be dispersed in the facet to aspect or again to entrance method. In some cases your chassis space for the battery pack will not be adaptable, so pay attention to These constraints before you start.
two. Think about the motor powering your RC car. Depending on the energy necessities, you'll be able to identify the number of batteries or cells you may need. This can be also if you can make your mind up the sort of batteries you can use - if you'd like to keep your NiMH batteries or enhance to LiPo.
3. Deciding your voltage is mostly a basic make any difference of addition. An ordinary mobile voltage is one.2v, so wired in the collection - 12 batteries will insert approximately 14.4v - which would energy an 14.four volt RC electric motor.
Subsequent, You'll have to collect your battery pack materials - so This is a sample shopping list. Keep in mind, we're assuming we are making a battery pack with 14.4v, as in the example previously mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (it is possible to order battery bars in bulk if you plan to build more than one pack and conserve $)
o Wire: You'll be wanting a higher top quality twelve gage by using a high strand depend. This type of wire, Using these qualities will probably be a lot more adaptable which is ideal together with staying more productive for electricity transmission.
o eighty-one hundred Watt Soldering Gun. You'll want a gun since you might be extra precise and more quickly - this is necessary due to heat sensitivity of batteries. The quicker and even more unique you could be, the less likely you'll be to break the battery.
o 60/forty Solder. This really is greater quality - also vital for brief and accurate work and steering clear of battery problems.
o Flux. It is a chemical cleansing agent that removes oxidation from metallic to aid soldering. You can utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive will likely be utilized to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries correctly and facilitate a tidy battery pack. The batteries finish up fundamentally wanting like cord Wooden - tidily bundled.
o Soldering "Supporting Hands" - optional. These products enable you to hold matters set up Whilst you solder.
o One more optional timesaver is to obtain a "Assisting Fingers" accent in your soldering station.
o Multi Meter. You will need a superior multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These applications will let you manage, strip and thoroughly Lower your twelve gage wire.
o The ultimate element could be the shrink wrap which can go across the full assembly and preserve it tidy. You can also need a warmth gun to heat and shrink the wrap.
So, you have recognized how to orient your batteries and the quantity of you require - now you get to operate on assembly. For this example, we are assembling twelve battery cells - 6 down a single side and six down the other.
After you identify the place the batteries are likely in relation on your chassis And exactly how they are going to become laid out, you could begin. For this example, for example we're undertaking 6 down one particular side and six down the other side.
Just to be certain we are on the exact same page, the final word purpose Here's for being operating wire through the positive terminal of the 1st battery to the constructive terminal on the electric RC motor and then operating Automated Guided Vehicles (AGV) Battery a wire within the adverse terminal on the last battery in your pack to the favourable terminal of one's other battery pack, thus making a accomplished circuit.
This signify you need to have sufficient wire to succeed in from the constructive terminal of the very first battery to that terminal and Similarly from your negative to complete the circuit with all your other battery pack so bear that in your mind.
Orientation. Align your to start with cell so that beneficial is pointing "upwards" and destructive is pointing "downwards" after which reverse the next battery so It is really opposite on down the road. If you bought the battery assembly jig, That is after you'd utilize it to align your cells and keep them set up.
Adhere. Adhere all the batteries together with your quick drying adhesive to They can be in order and aligned effectively.
Flux. Use your flux now within the relationship factors.
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. Utilizing the bar protects the battery and in the event the flux begins to bubble, you utilize your usage of solder. The goal is not to warmth the battery alone. Heating the battery is not merely counterproductive, considering the fact that in case you problems the battery it will never operate, but in addition unsafe as the cell could explode if overheated.
You'll want to accomplish a similar techniques for your remaining battery connections. That you are connecting the detrimental into the favourable time and again once again. You will then be Completely ready to connect wiring in your battery pack.
The wires should be pre-tinned which mean you have to strip off a quarter inch of your protecting plastic wiring sheath, make use of the flux to wash them - utilize the flux liberally - heat your solder gun after which you can heat the wire and circulation the solder to the wire until finally thoroughly saturated. You are going to also want solder within the batteries And so the solder will act as being the connector With all the battery.
As soon as the two, six cell battery packs are entire, you'll want to utilize the shrink wrap to secure them - and you will have your entire battery pack! Now you can electricity and fly your RC helicopter, aircraft, boat, auto or truck without difficulties!
