Constructing an RC Battery Pack - A Fundamental How-To
If you're keen on RC, you realize the significance of a battery pack. The sort of batteries you end up picking, how effectively your pack is assembled And the way efficiently you cost them are all vital areas to powering your RC automobile. Certain, You should purchase a battery pack pre-assembled, but You may as well Establish your individual and have the gratification of planning and powering your individual automobile.
The very first thing you must do is when you select to put together a battery pack is what you are powering and how much juice you may need. You also require to consider the subsequent:
one. Think about the chassis of the car or truck. The sort of car or truck isn't going to matter as much as the amount of Area in which you have to maneuver. The batteries may possibly should be oriented inside of a flat pack, a clustered pack or as both equally. It's also wise to think of the distribution of weight within your automobile - whether or not the battery fat will likely be dispersed inside a side to side or again to entrance way. Sometimes your chassis Room for a battery pack is not really adaptable, so pay attention to Those people constraints before you start.
2. Look at the motor powering your RC motor vehicle. Based on the electrical power needs, you'll determine the amount of batteries or cells you will need. This is also after you can choose the kind of batteries you may use - if you wish to maintain your NiMH batteries or improve to LiPo.
three. Analyzing your voltage is really a straightforward issue of addition. A standard cell voltage is 1.2v, so wired in the sequence - twelve batteries will incorporate nearly 14.4v - which might electricity an 14.four volt RC electric powered motor.
Next, you'll need to gather your battery pack supplies - so This is a sample browsing listing. Try to remember, we're assuming we're creating a battery pack with 14.4v, as in the example earlier mentioned:
o twelve Batteries or Battery Cells
o twelve Battery Bars (you are able to order battery bars in bulk if you propose to develop more than one pack and save $)
o Wire: You'll want the next top quality 12 gage which has a substantial strand rely. This type of wire, Using these characteristics might be far more versatile which is right and also currently being more successful for ability transmission.
o 80-100 Watt Soldering Gun. You will need a gun since you could be a lot more correct and quicker - this is essential as a result of warmth sensitivity of batteries. The more rapidly and much more certain you can be, the less likely you'll be to break the battery.
o 60/forty Solder. This is often greater quality - also significant for quick and correct operate and staying away from battery problems.
o Flux. This is the chemical cleansing agent that gets rid of oxidation from metal to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive will be accustomed to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries properly and facilitate a tidy battery pack. The batteries finish up fundamentally looking like twine Wooden - tidily bundled.
o Soldering "Helping Fingers" - optional. These products permit you to keep points set up As you solder.
o A further optional timesaver is to get a "Assisting Fingers" accessory in your soldering station.
o Multi Meter. You will need a excellent multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These applications can assist you manage, strip and Automated Guided Vehicles (AGV) Battery effectively Reduce your 12 gage wire.
o The final ingredient would be the shrink wrap which can go round the total assembly and preserve it tidy. You may also require a heat gun to warmth and shrink the wrap.
So, you have discovered how to orient your batteries and what number of you require - now you receive to work on assembly. For this instance, we're assembling twelve battery cells - six down one side and 6 down another.
Once you detect the place the batteries are going in relation for your chassis and how they're going to be laid out, it is possible to commence. For this example, for instance we're carrying out six down one particular aspect and six down another side.
Just to be certain we're on the same web page, the last word objective Here's to generally be managing wire in the beneficial terminal of the first battery towards the constructive terminal on the electric RC motor after which you can working a wire in the detrimental terminal on the final battery in the pack for the good terminal of one's other battery pack, thus developing a accomplished circuit.
This signify you need to have sufficient wire to reach with the positive terminal of the initially battery to that terminal and Furthermore from your detrimental to accomplish the circuit using your other battery pack so bear that in your mind.
Orientation. Align your very first cell making sure that favourable is pointing "upwards" and unfavorable is pointing "downwards" after which you can reverse another battery so it's reverse on down the line. If you bought the battery assembly jig, That is if you'd utilize it to align your cells and keep them set up.
Adhere. Adhere the many batteries along with your fast drying adhesive to They're to be able and aligned properly.
Flux. Make use of your flux now to the relationship details.
Relationship - Make use of your battery bars to attach your cells. You will need to heat up your soldering gun and heat up the battery bar. Utilizing the bar safeguards the battery and when the flux starts to bubble, you utilize your utilization of solder. The target is not to warmth the battery by itself. Heating the battery is don't just counterproductive, given that if you injury the battery it is not going to get the job done, but will also unsafe as the cell may well explode if overheated.
You will need to complete exactly the same actions for the remaining battery connections. You're connecting the unfavorable into the optimistic repeatedly yet again. You are going to then be Prepared to connect wiring to the battery pack.
The wires should be pre-tinned which indicate you should strip off a quarter inch with the protective plastic wiring sheath, make use of the flux to scrub them - apply the flux liberally - heat your solder gun then warmth the wire and flow the solder into the wire until eventually thoroughly saturated. You may also want solder over the batteries Hence the solder will act given that the connector Using the battery.
As soon as the two, six cell battery packs are full, you'll be wanting to make use of the shrink wrap to secure them - and you will have your total battery pack! Now you'll electric power and fly your RC helicopter, aircraft, boat, car or truck without having issues!
