Constructing an RC Battery Pack - A Fundamental How-To
If you like RC, you know the importance of a battery pack. The kind of batteries you end up picking, how effectively your pack is assembled and how effectively you cost them are all vital features to powering your RC motor vehicle. Certain, You should purchase a battery pack pre-assembled, but You can even Establish your very own and acquire the pleasure of developing and powering your own personal motor vehicle.
The first thing you should do is when you select to put with each other a battery pack is what you're powering and the amount of juice you require. Additionally you need to think about the following:
1. Think about the chassis of your car or truck. The kind of automobile does not subject approximately the quantity of House in which It's important to maneuver. The batteries may must be oriented inside a flat pack, a clustered pack or as both of those. You should also contemplate the distribution of weight in the auto - whether the battery body weight will likely be dispersed in a aspect to facet or back again to entrance way. In some cases your chassis House for your battery pack will not be adaptable, so be familiar with All those constraints before you start.
2. Look at the motor powering your RC car or truck. Based on the electricity needs, you can decide the number of batteries or cells you require. This can be also after you can make your mind up the kind of batteries you are going to use - in order to Automated Guided Vehicles (AGV) Battery keep your NiMH batteries or up grade to LiPo.
3. Pinpointing your voltage can be a easy subject of addition. An ordinary mobile voltage is one.2v, so wired inside a collection - twelve batteries will include nearly 14.4v - which would power an 14.four volt RC electric motor.
Upcoming, You will need to gather your battery pack supplies - so here's a sample procuring record. Bear in mind, we are assuming we are creating a battery pack with fourteen.4v, as in the instance previously mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you may buy battery bars in bulk if you propose to create multiple pack and conserve $)
o Wire: You will need a greater excellent twelve gage which has a superior strand depend. Such a wire, Using these characteristics will likely be much more versatile which is ideal as well as remaining much more effective for ability transmission.
o eighty-100 Watt Soldering Gun. You will need a gun because you may be much more specific and more rapidly - this is essential due to the heat sensitivity of batteries. The more quickly and even more particular you are able to be, the not as likely you'll be to break the battery.
o sixty/forty Solder. This is often larger high-quality - also vital for fast and correct perform and preventing battery destruction.
o Flux. It is a chemical cleansing agent that eliminates oxidation from steel to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive might be used to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries properly and facilitate a tidy battery pack. The batteries end up generally hunting like twine wood - tidily bundled.
o Soldering "Encouraging Fingers" - optional. These gadgets allow you to maintain factors in position As you solder.
o An additional optional timesaver is to obtain a "Helping Arms" accent in your soldering station.
o Multi Meter. You will need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These resources will let you tackle, strip and adequately cut your 12 gage wire.
o The ultimate ingredient is definitely the shrink wrap that will go within the full assembly and maintain it tidy. You are going to also require a warmth gun to heat and shrink the wrap.
So, you have determined the way to orient your batteries and the amount of you may need - now you can get to work on assembly. For this instance, we're assembling twelve battery cells - six down 1 aspect and six down another.
Once you establish exactly where the batteries are likely in relation on your chassis And the way they're going to become laid out, you'll be able to begin. For this example, for example we are doing six down a person facet and 6 down the opposite aspect.
Just to make sure we're on a similar site, the final word purpose here is to generally be running wire in the beneficial terminal of one's 1st battery on the beneficial terminal on the electric RC motor and then jogging a wire within the detrimental terminal on the final battery with your pack to the good terminal of your other battery pack, therefore making a accomplished circuit.
This mean you might want to have sufficient wire to succeed in within the good terminal of your initially battery to that terminal and Furthermore from your detrimental to complete the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your first cell in order that positive is pointing "upwards" and detrimental is pointing "downwards" and then reverse the following battery so It truly is reverse on down the road. If you purchased the battery assembly jig, This is often any time you'd utilize it to align your cells and hold them in position.
Adhere. Adhere every one of the batteries together with your quickly drying adhesive to They are really in order and aligned correctly.
Flux. Make use of your flux now within the link factors.
Connection - Make use of your battery bars to attach your cells. You'll need to warmth up your soldering gun and warmth up the battery bar. Utilizing the bar shields the battery and in the event the flux begins to bubble, you employ your usage of solder. The purpose is to NOT warmth the battery itself. Heating the battery is not only counterproductive, due to the fact if you injury the battery it is not going to operate, but additionally risky because the cell could explode if overheated.
You'll want to accomplish a similar techniques for that remaining battery connections. You're connecting the detrimental towards the favourable over and over all over again. You are going to then be Prepared to connect wiring to your battery pack.
The wires need to be pre-tinned which signify you must strip off 1 / 4 inch in the protective plastic wiring sheath, use the flux to scrub them - apply the flux liberally - heat your solder gun after which heat the wire and stream the solder in to the wire until finally thoroughly saturated. You can also want solder over the batteries Hence the solder will act since the connector Together with the battery.
Once the two, six cell battery packs are full, you will need to employ the shrink wrap to safe them - and you'll have your complete battery pack! Now you'll be able to electricity and fly your RC helicopter, plane, boat, auto or truck without any troubles!
