Making an RC Battery Pack - A Basic How-To
If you like RC, you are aware of the importance of a battery pack. The type of batteries you choose, how well your pack is assembled and how efficiently you demand them are all critical elements to powering your RC motor vehicle. Sure, you can buy a battery pack pre-assembled, but It's also possible to Create your own and acquire the satisfaction of creating and powering your own personal car.
The first thing you might want to do is when you decide To place with each other a battery pack is what you are powering and just how much juice you require. Additionally you require to consider the following:
one. Consider the chassis of your respective car or truck. The kind of motor vehicle does not matter as much as the quantity of Area through which You need to maneuver. The batteries may perhaps have to be oriented in the flat pack, a clustered pack or as both. It's also advisable to think of the distribution of bodyweight as part of your car - whether or not the battery weight is going to be distributed in a very facet to facet or again to front manner. In some cases your chassis House for any battery pack isn't adaptable, so be familiar with Individuals constraints before you start.
2. Look at the motor powering your RC car. Depending on the electric power demands, you can decide the number of batteries or cells you would like. That is also if you can make a decision the kind of batteries you'll use - in order to maintain your NiMH batteries or up grade to LiPo.
three. Deciding your voltage is mostly a very simple make a difference of addition. A standard cell voltage is one.2v, so wired inside a sequence - 12 batteries will incorporate up to fourteen.4v - which might electricity an 14.4 volt RC electrical motor.
Next, You'll have to collect your battery pack provides - so This is a sample purchasing record. Bear in mind, we're assuming we are making a battery pack with fourteen.4v, as in the example higher than:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you may order battery bars in bulk if you intend to develop more than one pack and help you save $)
o Wire: You will need a better high quality 12 gage which has a significant strand depend. Such a wire, Using these attributes might be more versatile which is right in addition to being extra productive for electrical power transmission.
o eighty-a hundred Watt Soldering Gun. You'll want a gun simply because you might be more specific and a lot quicker - this is critical due to heat sensitivity of batteries. The more quickly plus much more particular you are able to be, the less likely You will be to damage the battery.
o sixty/forty Solder. This is larger top quality - also vital for brief and accurate perform and keeping away from Automated Guided Vehicles (AGV) Battery battery problems.
o Flux. This is the chemical cleansing agent that eliminates oxidation from metal to facilitate soldering. You can utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive is going to be utilized to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries correctly and facilitate a tidy battery pack. The batteries find yourself basically hunting like cord wood - tidily bundled.
o Soldering "Serving to Hands" - optional. These products let you keep matters in place Whilst you solder.
o Yet another optional timesaver is to acquire a "Assisting Arms" accessory on your soldering station.
o Multi Meter. You need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools will let you manage, strip and effectively Slice your 12 gage wire.
o The final component would be the shrink wrap which is able to go across the full assembly and retain it tidy. You will also need a warmth gun to heat and shrink the wrap.
So, you have recognized how to orient your batteries and the amount of you would like - now you will get to operate on assembly. For this instance, we're assembling twelve battery cells - 6 down a person aspect and 6 down the other.
After you identify where by the batteries are likely in relation on your chassis And just how they're going to generally be laid out, you are able to begin. For this example, let's say we are carrying out six down 1 side and 6 down another side.
Just to be certain we are on a similar web page, the last word aim Here's being jogging wire from the good terminal of one's 1st battery towards the constructive terminal on the electrical RC motor after which managing a wire from the damaging terminal on the final battery with your pack to your optimistic terminal within your other battery pack, therefore creating a finished circuit.
This indicate you have to have adequate wire to succeed in from the good terminal of one's 1st battery to that terminal and likewise through the unfavorable to complete the circuit with all your other battery pack so bear that in mind.
Orientation. Align your initial cell to make sure that favourable is pointing "upwards" and adverse is pointing "downwards" after which reverse another battery so It can be reverse on down the road. If you purchased the battery assembly jig, This is often once you'd use it to align your cells and keep them in position.
Adhere. Stick all the batteries together with your quick drying adhesive to they are so as and aligned thoroughly.
Flux. Make use of your flux now around the connection points.
Relationship - Make use of your battery bars to attach your cells. You will need to warmth up your soldering gun and heat up the battery bar. Using the bar safeguards the battery and if the flux begins to bubble, you hire your usage of solder. The intention is to NOT warmth the battery by itself. Heating the battery is not simply counterproductive, due to the fact if you destruction the battery it won't operate, and also harmful because the mobile could explode if overheated.
You'll want to accomplish exactly the same actions for that remaining battery connections. You might be connecting the unfavorable to the good over and over again. You'll then be Prepared to connect wiring towards your battery pack.
The wires have to be pre-tinned which necessarily mean you must strip off a quarter inch in the protecting plastic wiring sheath, make use of the flux to scrub them - apply the flux liberally - warmth your solder gun and then heat the wire and move the solder in to the wire right until totally saturated. You will also want solder over the batteries Hence the solder will act because the connector Together with the battery.
After the two, six cell battery packs are full, you'll be wanting to use the shrink wrap to safe them - and you'll have your comprehensive battery pack! Now you can electric power and fly your RC helicopter, airplane, boat, vehicle or truck without any challenges!
