Building an RC Battery Pack - A Basic How-To
If you're keen on RC, you recognize the necessity of a battery pack. The sort of batteries you select, how perfectly your pack is assembled and how proficiently you charge them are all important aspects to powering your RC vehicle. Certain, You should buy a battery pack pre-assembled, but You may also build your individual and obtain the satisfaction of coming up with and powering your own personal auto.
The first thing you need to do is when you decide to put jointly a battery pack is what you're powering and simply how much juice you require. You furthermore mght want to consider the following:
1. Consider the chassis of your respective vehicle. The sort of car or truck does not matter just as much as the amount of House in which You will need to maneuver. The batteries may well have to be oriented within a flat pack, a clustered pack or as equally. You should also consider the distribution of bodyweight as part of your auto - if the battery body weight will probably be distributed inside a aspect to side or back to front way. In some cases your chassis space for a battery pack is not really adaptable, so concentrate on All those constraints Before you begin.
2. Consider the motor powering your RC car. Based on the ability specifications, you'll be able to establish the quantity of batteries or cells you will need. This is often also whenever you can choose the type of batteries you Automated Guided Vehicles (AGV) Battery are going to use - if you wish to maintain your NiMH batteries or enhance to LiPo.
3. Figuring out your voltage is known as a straightforward make any difference of addition. An ordinary cell voltage is one.2v, so wired inside a collection - 12 batteries will insert around 14.4v - which might electrical power an fourteen.four volt RC electrical motor.
Upcoming, You will need to collect your battery pack provides - so Here is a sample purchasing list. Keep in mind, we're assuming we are making a battery pack with fourteen.4v, as in the instance earlier mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you'll be able to purchase battery bars in bulk if you plan to develop more than one pack and help save $)
o Wire: You'll want the next high quality 12 gage having a superior strand depend. This kind of wire, with these qualities will likely be additional adaptable which is ideal and also staying more economical for electric power transmission.
o eighty-one hundred Watt Soldering Gun. You will need a gun simply because you is usually far more exact and a lot quicker - this is essential due to the heat sensitivity of batteries. The more rapidly and much more specific you could be, the more unlikely You will be to damage the battery.
o sixty/40 Solder. This is greater good quality - also vital for fast and correct work and averting battery hurt.
o Flux. That is a chemical cleansing agent that removes oxidation from metal to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive will probably be accustomed to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries properly and facilitate a tidy battery pack. The batteries end up mainly on the lookout like wire wood - tidily bundled.
o Soldering "Serving to Arms" - optional. These products assist you to maintain items set up When you solder.
o Yet another optional timesaver is to secure a "Encouraging Fingers" accent on your soldering station.
o Multi Meter. You need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will let you take care of, strip and effectively Lower your twelve gage wire.
o The final component is definitely the shrink wrap which will go around the overall assembly and keep it tidy. You may also need a warmth gun to heat and shrink the wrap.
So, you have discovered ways to orient your batteries and what number of you will need - now you obtain to work on assembly. For this example, we're assembling twelve battery cells - 6 down one facet and six down one other.
After you identify exactly where the batteries are likely in relation to your chassis And exactly how they are going to become laid out, it is possible to start off. For this example, for example we are accomplishing 6 down one facet and six down the opposite side.
Just to ensure we're on the identical webpage, the ultimate objective here is to become running wire through the positive terminal of one's first battery to the good terminal on the electric RC motor and after that operating a wire from your unfavorable terminal on the last battery as part of your pack towards the favourable terminal within your other battery pack, therefore developing a finished circuit.
This necessarily mean you should have ample wire to reach in the favourable terminal of your respective very first battery to that terminal and Also within the destructive to accomplish the circuit with the other battery pack so bear that in mind.
Orientation. Align your initial mobile to ensure good is pointing "upwards" and unfavorable is pointing "downwards" after which reverse another battery so It is reverse on down the road. If you purchased the battery assembly jig, This really is after you'd utilize it to align your cells and keep them in position.
Adhere. Stick the many batteries together with your speedy drying adhesive to They're to be able and aligned thoroughly.
Flux. Make use of your flux now on the connection factors.
Relationship - Make use of your battery bars to connect your cells. You'll need to heat up your soldering gun and warmth up the battery bar. Using the bar safeguards the battery and once the flux starts to bubble, you make use of your use of solder. The aim is to NOT warmth the battery by itself. Heating the battery is not just counterproductive, due to the fact for those who destruction the battery it won't get the job done, but also unsafe because the mobile could explode if overheated.
You will need to accomplish the same techniques for your remaining battery connections. That you are connecting the destructive to the beneficial again and again once more. You'll then be All set to attach wiring to your battery pack.
The wires have to be pre-tinned which imply you'll want to strip off 1 / 4 inch of the protective plastic wiring sheath, make use of the flux to scrub them - implement the flux liberally - heat your solder gun and then heat the wire and movement the solder into the wire until finally carefully saturated. You will also want solder to the batteries Hence the solder will act as the connector Along with the battery.
Once the two, 6 cell battery packs are complete, you'll be wanting to utilize the shrink wrap to secure them - and you'll have your complete battery pack! Now you can energy and fly your RC helicopter, airplane, boat, car or truck with no challenges!
