Building an RC Battery Pack - A Basic How-To
If you like RC, you recognize the importance of a battery pack. The type of batteries you end up picking, how well your pack is assembled And exactly how efficiently you charge them are all crucial areas to powering your RC car. Certain, You should purchase a battery pack pre-assembled, but It's also possible to Establish your own and acquire the pleasure of coming up with and powering your own car.
The first thing you should do is when you choose to put collectively a battery pack is what you are powering and the amount of juice you need. Additionally you need to have to consider the subsequent:
one. Think about the chassis of one's auto. The kind of car does not make any difference around the quantity of space through which You need to maneuver. The batteries may must be oriented inside of a flat pack, a clustered pack or as the two. It's also advisable to take into consideration the distribution of bodyweight in your vehicle - whether the battery fat will probably be dispersed in the facet to aspect or again to front method. In some instances your chassis Area for a battery pack will not be adaptable, so pay attention to those constraints before you start.
2. Consider the motor powering your RC car. Depending on the electric power specifications, you'll identify the number of batteries or cells you may need. This is certainly also any time you can come to a decision the type of batteries you may use - if you would like maintain your NiMH batteries or enhance to LiPo.
three. Figuring out your voltage can be a uncomplicated issue of addition. A regular cell voltage is one.2v, so wired in a very series - twelve batteries will add nearly 14.4v - which would energy an 14.four volt RC electric powered motor.
Next, you'll need to collect your battery pack materials - so This is a sample buying list. Recall, we're assuming we're creating a battery pack with fourteen.4v, as in the instance previously mentioned:
o twelve Batteries or Battery Cells
o twelve Battery Bars (you may get battery bars in bulk if you intend to make multiple pack and help save $)
o Wire: You'll want a better good quality 12 gage with a substantial strand rely. This kind of wire, with these properties is going to be extra versatile which is good in addition to currently being far more productive for energy transmission.
o eighty-a hundred Watt Soldering Gun. You'll want a gun simply because you might be a lot more specific and quicker - this is critical as a result of heat sensitivity of batteries. The more rapidly plus more specific you are able to be, the not as likely You will be to damage the battery.
o sixty/40 Solder. That is greater high-quality - also important for quick and accurate operate and preventing battery harm.
o Flux. That is a chemical cleaning agent that removes oxidation from metal to aid soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. Automated Guided Vehicles (AGV) Battery This rapid drying adhesive will probably be utilized to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries effectively and aid a tidy battery pack. The batteries end up mainly on the lookout like twine Wooden - tidily bundled.
o Soldering "Encouraging Hands" - optional. These products permit you to maintain matters in place When you solder.
o One more optional timesaver is to get a "Helping Palms" accessory 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 resources will help you take care of, strip and correctly Reduce your twelve gage wire.
o The ultimate component is definitely the shrink wrap which is able to go round the entire assembly and keep it tidy. You'll also need a warmth gun to warmth and shrink the wrap.
So, you have determined the way to orient your batteries and the amount of you may need - now you will get to operate on assembly. For this example, we're assembling twelve battery cells - 6 down one facet and six down the opposite.
As soon as you discover in which the batteries are likely in relation on your chassis And the way they're going being laid out, you could begin. For this instance, let's say we are executing six down a person facet and six down one other side.
Just to ensure we're on the same site, the final word target here is to generally be functioning wire through the positive terminal of your to start with battery towards the optimistic terminal on the electric RC motor then operating a wire within the negative terminal on the last battery in the pack to your good terminal within your other battery pack, thereby creating a finished circuit.
This signify you'll want to have adequate wire to reach within the beneficial terminal of one's initial battery to that terminal and Similarly with the negative to accomplish the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your to start with cell so that optimistic is pointing "upwards" and negative is pointing "downwards" after which reverse the following battery so it's opposite on down the road. If you bought the battery assembly jig, This is certainly when you'd use it to align your cells and keep them set up.
Adhere. Adhere each of the batteries along with your rapid drying adhesive to They're in order and aligned correctly.
Flux. Make use of your flux now around the connection details.
Connection - Use 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 once the flux starts to bubble, you utilize your use of solder. The target is to NOT warmth the battery by itself. Heating the battery is not merely counterproductive, given that in the event you hurt the battery it would not operate, but in addition perilous since the cell may possibly explode if overheated.
You'll be wanting to accomplish the same measures for your remaining battery connections. That you are connecting the damaging towards the positive again and again once again. You can expect to then be ready to attach wiring in your battery pack.
The wires have to be pre-tinned which indicate you have to strip off a quarter inch with the protecting plastic wiring sheath, make use of the flux to wash them - implement the flux liberally - heat your solder gun and then heat the wire and flow the solder to the wire until finally comprehensively saturated. You may also want solder about the batteries so the solder will act given that the connector Using the battery.
After the two, 6 cell battery packs are total, you'll be wanting to hire the shrink wrap to safe them - and you'll have your entire battery pack! Now you can power and fly your RC helicopter, airplane, boat, automobile or truck with no complications!
