Creating an RC Battery Pack - A Fundamental How-To
If you're keen on RC, you recognize the value of a battery pack. The sort of batteries you select, how well your pack is assembled And the way proficiently you demand them are all important areas to powering your RC automobile. Positive, you can buy a battery pack pre-assembled, but You may as well Make your very own and obtain the gratification of building and powering your own vehicle.
The very first thing you need to do is when you select to put together a battery pack is what you are powering and how much juice you would like. You furthermore may want to think about the next:
one. Look at the chassis of your respective car. The type of auto won't make any difference approximately the level of House during which you have to maneuver. The batteries may need to be oriented in a flat pack, a clustered pack or as equally. It's also wise to think about the distribution of bodyweight in your motor vehicle - whether the battery fat will likely be dispersed inside of a side to aspect or again to front method. In some cases your chassis House for any battery pack will not be adaptable, so be aware of These constraints before you start.
two. Look at the motor powering your RC automobile. Dependant upon the electric power requirements, you can figure out how many batteries or cells you need. This is often also once you can make your mind up the type of batteries you can expect to use - in order to keep your NiMH batteries or enhance to LiPo.
3. Identifying your voltage can be a very simple issue of addition. A regular cell Automated Guided Vehicles (AGV) Battery voltage is one.2v, so wired in the sequence - 12 batteries will insert as much as fourteen.4v - which would ability an 14.4 volt RC electric powered motor.
Future, you'll need to collect your battery pack provides - so Here is a sample procuring list. Bear in mind, we are assuming we're creating a battery pack with 14.4v, as in the example over:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you could buy battery bars in bulk if you propose to create multiple pack and conserve $)
o Wire: You'll want a better quality twelve gage using a significant strand count. This type of wire, with these characteristics is going to be far more flexible which is right and also being additional efficient for energy transmission.
o 80-a hundred Watt Soldering Gun. You'll be wanting a gun since you may be extra precise and a lot quicker - this is essential due to the heat sensitivity of batteries. The quicker plus much more unique it is possible to be, the less likely You will be to damage the battery.
o sixty/40 Solder. That is greater high quality - also important for quick and correct do the job and staying away from battery damage.
o Flux. It is a chemical cleansing agent that gets rid of oxidation from metallic to facilitate soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive are going to be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries correctly and facilitate a tidy battery pack. The batteries end up mainly wanting like wire Wooden - tidily bundled.
o Soldering "Serving to Fingers" - optional. These products enable you to keep things set up As you solder.
o A different optional timesaver is to acquire a "Assisting Hands" accent for your soldering station.
o Multi Meter. You need a great multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will assist you to manage, strip and effectively Slash your 12 gage wire.
o The final ingredient will be the shrink wrap that can go across the whole assembly and keep it tidy. You are going to also need a heat gun to heat and shrink the wrap.
So, you've discovered the best way to orient your batteries and the quantity of you require - now you have to work on assembly. For this example, we're assembling twelve battery cells - six down a person side and 6 down the other.
As you establish exactly where the batteries are going in relation for your chassis And just how they're going to be laid out, you'll be able to start off. For this instance, for example we're undertaking six down 1 facet and six down another facet.
Just to ensure we are on precisely the same web site, the final word objective Here's being managing wire through the beneficial terminal of one's 1st battery to the good terminal on the electric RC motor and after that running a wire from the destructive terminal on the last battery with your pack to the positive terminal of your other battery pack, thereby developing a done circuit.
This indicate you must have enough wire to reach with the positive terminal within your first battery to that terminal and likewise from your damaging to accomplish the circuit using your other battery pack so bear that in your mind.
Orientation. Align your 1st mobile so that optimistic is pointing "upwards" and destructive is pointing "downwards" after which reverse the following battery so It is reverse on down the road. If you bought the battery assembly jig, This can be if you'd utilize it to align your cells and keep them in position.
Adhere. Adhere the many batteries along with your speedy drying adhesive to they are in order and aligned thoroughly.
Flux. Make use of your flux now about the link points.
Connection - Use your battery bars to attach your cells. You will need to heat up your soldering gun and heat up the battery bar. Using the bar protects the battery and once the flux begins to bubble, you make use of your use of solder. The aim is not to heat the battery by itself. Heating the battery is not simply counterproductive, given that in the event you hurt the battery it will not perform, but in addition unsafe as the cell may possibly explode if overheated.
You will need to finish a similar measures with the remaining battery connections. You might be connecting the negative to the favourable over and over once more. You may then be ready to connect wiring to the battery pack.
The wires must be pre-tinned which indicate you need to strip off a quarter inch from the protective plastic wiring sheath, utilize the flux to wash them - apply the flux liberally - heat your solder gun and after that warmth the wire and flow the solder into your wire until eventually completely saturated. You can also want solder to the batteries Hence the solder will act since the connector Together with the battery.
After the two, 6 mobile battery packs are entire, you'll want to utilize the shrink wrap to safe them - and you'll have your full battery pack! Now you'll energy and fly your RC helicopter, aircraft, boat, auto or truck without having complications!
