Constructing an RC Battery Pack - A Standard How-To
If you like RC, you understand the value of a battery pack. The type of batteries you decide on, how effectively your pack is assembled And just how efficiently you cost them are all significant factors to powering your RC motor vehicle. Positive, you can buy a battery pack pre-assembled, but You can even Make your very own and get the fulfillment of building and powering your own automobile.
The very first thing you need to do is when you decide to put with each other a battery pack is what you're powering and how much juice you would like. You also require to think about the subsequent:
one. Think about the chassis within your automobile. The sort of car doesn't matter just as much as the level of Room during which You need to maneuver. The batteries may well have to be oriented in a very flat pack, a clustered pack or as equally. You should also consider the distribution of body weight with your vehicle - if the battery bodyweight is going to be dispersed in a facet to facet or back again to entrance method. In some instances your chassis Room for your battery pack is just not adaptable, so be familiar with These constraints before you start.
2. Think about the motor powering your RC auto. With regards to the power demands, you'll ascertain the amount of batteries or cells you may need. This can be also once you can come to a decision the type of batteries you may use - if you wish to maintain your NiMH batteries or improve to LiPo.
three. Figuring out your voltage can be a simple make a difference of addition. A standard cell voltage is 1.2v, so wired inside a collection - twelve batteries will add as many as fourteen.4v - which would power an fourteen.four volt RC electrical motor.
Following, You will need to assemble your battery pack provides - so This is a sample searching list. Don't forget, we're assuming we are creating a battery pack with fourteen.4v, as in the example over:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you could get battery bars in bulk if you plan to construct multiple pack and conserve $)
o Wire: You will need a better excellent 12 gage using a significant strand rely. This type of wire, Using these characteristics is going to be additional adaptable which is right together with remaining far more productive for energy transmission.
o eighty-100 Watt Soldering Gun. You'll want a gun as you can be a lot more correct and a lot quicker - this is important due to the heat sensitivity of batteries. The a lot quicker and a lot more precise you are able to be, the more unlikely you'll be to break the battery.
o sixty/40 Solder. This can be higher high-quality - also essential for quick and correct perform and steering clear of battery injury.
o Flux. It is a chemical cleansing agent that removes oxidation from steel to facilitate soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive might be accustomed to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries appropriately and facilitate a tidy battery pack. The batteries turn out in essence seeking like cord wood - tidily bundled.
o Soldering "Helping Palms" - optional. These gadgets let you hold matters in place When you solder.
o Yet another optional timesaver is to obtain a "Encouraging Arms" accent for your personal soldering station.
o Multi Meter. You'll need a great multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These resources will help you manage, strip and correctly Lower your 12 gage wire.
o The ultimate ingredient is definitely the shrink wrap which will go round the whole assembly and preserve it tidy. You will also have to have a warmth gun to heat and shrink the wrap.
So, you have determined how to orient your batteries and how many you require - now you will get to work on assembly. For this example, we are assembling twelve battery cells - six down one particular facet and six down the other.
As you establish in which the batteries are going in relation on your chassis And exactly how they're going for being laid out, you are able to get started. For this example, as an example we're carrying out 6 down one side Automated Guided Vehicles (AGV) Battery and six down the opposite aspect.
Just to be certain we're on a similar site, the last word goal Here's to get managing wire in the good terminal of your initial battery on the optimistic terminal on the electrical RC motor after which you can managing a wire in the damaging terminal on the final battery inside your pack to your constructive terminal of one's other battery pack, therefore developing a completed circuit.
This signify you should have enough wire to succeed in in the positive terminal of one's initially battery to that terminal and Furthermore through the detrimental to finish the circuit with all your other battery pack so bear that in mind.
Orientation. Align your initially cell to ensure that good is pointing "upwards" and adverse is pointing "downwards" after which you can reverse the next battery so It really is opposite on down the line. If you bought the battery assembly jig, This really is any time you'd use it to align your cells and maintain them in place.
Adhere. Stick all the batteries together with your rapid drying adhesive to They are really in order and aligned appropriately.
Flux. Make use of your flux now over the connection points.
Relationship - Make use of your battery bars to connect your cells. You'll have to warmth up your soldering gun and heat up the battery bar. Utilizing the bar safeguards the battery and if the flux starts to bubble, you employ your usage of solder. The intention is to NOT heat the battery itself. Heating the battery is not only counterproductive, since for those who injury the battery it will never function, but in addition harmful since the cell might explode if overheated.
You'll want to finish the identical techniques for your remaining battery connections. You might be connecting the adverse towards the constructive over and over yet again. You'll then be Completely ready to connect wiring towards your battery pack.
The wires must be pre-tinned which mean you need to strip off a quarter inch from the protecting plastic wiring sheath, make use of the flux to scrub them - implement the flux liberally - heat your solder gun after which you can warmth the wire and circulation the solder in to the wire until finally comprehensively saturated. You will also want solder around the batteries Therefore the solder will act since the connector While using the battery.
After the two, six mobile battery packs are comprehensive, you'll be wanting to make use of the shrink wrap to protected them - and you'll have your comprehensive battery pack! Now you'll be able to power and fly your RC helicopter, plane, boat, motor vehicle or truck without difficulties!
