Building an RC Battery Pack - A Standard How-To
If you like RC, you recognize the value of a battery pack. The type of batteries you select, how nicely your pack is assembled And just how proficiently you cost them are all significant features to powering your RC car or truck. Certain, You should buy a battery pack pre-assembled, but It's also possible to Construct your individual and acquire the satisfaction of developing and powering your own auto.
The first thing you'll want to do is when you select To place with each other a battery pack is what you're powering and how much juice you'll need. You furthermore mght Automated Guided Vehicles (AGV) Battery have to have to consider the following:
one. Think about the chassis of the car or truck. The type of automobile won't issue as much as the level of space through which You should maneuver. The batteries might should be oriented inside of a flat pack, a clustered pack or as both. You should also think of the distribution of body weight with your automobile - whether the battery body weight is going to be distributed inside of a facet to aspect or back again to front fashion. Occasionally your chassis House for your battery pack is just not adaptable, so be familiar with Those people constraints Before you begin.
two. Consider the motor powering your RC motor vehicle. Depending upon the electrical power necessities, you can identify how many batteries or cells you would like. This is also when you can come to a decision the kind of batteries you'll use - if you need to maintain your NiMH batteries or enhance to LiPo.
three. Deciding your voltage is really a straightforward matter of addition. A standard mobile voltage is one.2v, so wired inside a collection - 12 batteries will incorporate around fourteen.4v - which would electrical power an fourteen.4 volt RC electric powered motor.
Up coming, You will need to gather your battery pack materials - so Here is a sample procuring record. Keep in mind, we're assuming we're making a battery pack with fourteen.4v, as in the example over:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you'll be able to purchase battery bars in bulk if you plan to create multiple pack and conserve $)
o Wire: You'll be wanting a better good quality twelve gage by using a substantial strand count. This type of wire, with these qualities are going to be extra adaptable which is ideal and also staying additional successful for power transmission.
o eighty-100 Watt Soldering Gun. You will need a gun simply because you is usually additional exact and a lot quicker - this is essential as a result of heat sensitivity of batteries. The speedier and a lot more particular you can be, the less likely You will be to damage the battery.
o 60/40 Solder. This can be higher quality - also vital for quick and precise perform and steering clear of battery hurt.
o Flux. It is a chemical cleansing agent that eliminates oxidation from steel to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive might be utilized to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries effectively and aid a tidy battery pack. The batteries wind up generally searching like twine wood - tidily bundled.
o Soldering "Supporting Arms" - optional. These devices allow you to maintain issues in position As you solder.
o A different optional timesaver is to get a "Serving to Palms" accessory to your soldering station.
o Multi Meter. You will need a good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will allow you to deal with, strip and properly Lower your 12 gage wire.
o The final ingredient would be the shrink wrap that will go within the complete assembly and retain it tidy. You may also have to have a heat gun to heat and shrink the wrap.
So, you've got recognized how you can orient your batteries and the amount of you need - now you receive to work on assembly. For this instance, we're assembling twelve battery cells - 6 down one aspect and six down the opposite.
As you detect the place the batteries are likely in relation for your chassis and how they are going to generally be laid out, you could start. For this instance, let's say we're carrying out six down one particular facet and 6 down one other aspect.
Just to ensure we are on a similar web site, the ultimate goal here is for being running wire in the beneficial terminal of one's very first battery towards the optimistic terminal on the electrical RC motor and then functioning a wire from the negative terminal on the final battery with your pack for the good terminal of your other battery pack, thereby developing a finished circuit.
This imply you should have sufficient wire to succeed in from your optimistic terminal of one's initial battery to that terminal and likewise with the detrimental to complete the circuit with the other battery pack so bear that in your mind.
Orientation. Align your initially mobile to ensure beneficial is pointing "upwards" and adverse is pointing "downwards" and after that reverse another battery so it's opposite on down the line. If you purchased the battery assembly jig, This is often any time you'd utilize it to align your cells and hold them set up.
Adhere. Adhere the many batteries together with your fast drying adhesive to they are as a way and aligned properly.
Flux. Make use of your flux now to the connection details.
Connection - Make use of your battery bars to connect your cells. You'll need to heat up your soldering gun and heat up the battery bar. Using the bar guards the battery and if the flux begins to bubble, you utilize your usage of solder. The aim is to NOT heat the battery alone. Heating the battery is not only counterproductive, considering the fact that in case you problems the battery it would not do the job, but additionally perilous as the mobile may possibly explode if overheated.
You'll be wanting to complete the exact same techniques with the remaining battery connections. You might be connecting the unfavorable to your good over and over all over again. You'll then be All set to attach wiring on your battery pack.
The wires must be pre-tinned which mean you have to strip off a quarter inch of your protecting plastic wiring sheath, utilize the flux to scrub them - apply the flux liberally - warmth your solder gun and after that heat the wire and movement the solder in to the wire right up until extensively saturated. You will also want solder within the batteries Hence the solder will act since the connector Along with the battery.
Once the two, 6 mobile battery packs are total, you'll want to utilize the shrink wrap to protected them - and you will have your total battery pack! Now you'll ability and fly your RC helicopter, plane, boat, motor vehicle or truck without any issues!
