Constructing an RC Battery Pack - A Standard How-To
If you love RC, you already know the value of a battery pack. The kind of batteries you end up picking, how effectively your pack is assembled And the way competently you cost them are all critical aspects to powering your RC car or truck. Confident, You should buy a battery pack pre-assembled, but You can even Create your individual and acquire the fulfillment of planning and powering your own personal motor vehicle.
The first thing you need to do is when you select to put alongside one another a battery pack is what you're powering and just how much juice you would like. Additionally you want to consider the subsequent:
1. Look at the chassis of one's car or truck. The sort of automobile isn't going to make any difference around the quantity of Place in which You will need to maneuver. The batteries might have to be oriented in the flat pack, a clustered pack or as both equally. You should also take into consideration the distribution of pounds in your car or truck - if the battery bodyweight will probably be dispersed within a facet to facet or back again to front way. In some cases your chassis Place for a battery pack just isn't adaptable, so concentrate on those constraints before you start.
two. Look at the motor powering your RC motor vehicle. Based on the electric power needs, you'll ascertain what number of batteries or cells you need. That is also when you can determine the type of batteries you can use - if you need to maintain your NiMH batteries or update to LiPo.
three. Figuring out your voltage can be a very simple subject of addition. A typical mobile voltage is 1.2v, so wired in a series - twelve batteries will Automated Guided Vehicles (AGV) Battery add nearly 14.4v - which might electricity an fourteen.four volt RC electrical motor.
Up coming, You will need to gather your battery pack materials - so This is a sample browsing listing. Remember, we are assuming we're making a battery pack with 14.4v, as in the instance previously mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you may get battery bars in bulk if you propose to create more than one pack and help save $)
o Wire: You'll be wanting a greater excellent twelve gage by using a higher strand count. This kind of wire, Using these attributes might be much more flexible which is right together with currently being far more efficient for ability transmission.
o 80-100 Watt Soldering Gun. You'll want a gun since you might be more specific and quicker - this is essential because of the warmth sensitivity of batteries. The more rapidly and even more particular you may be, the less likely You will be to wreck the battery.
o sixty/40 Solder. This can be better high quality - also crucial for quick and precise operate and staying away from battery destruction.
o Flux. That is a chemical cleaning agent that removes oxidation from metallic to facilitate soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying adhesive will probably be utilized to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries properly and facilitate a tidy battery pack. The batteries wind up essentially looking like wire wood - tidily bundled.
o Soldering "Encouraging Fingers" - optional. These products allow you to keep points in place When you solder.
o An additional optional timesaver is to secure a "Encouraging Fingers" accessory on your soldering station.
o Multi Meter. You need a good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications can help you cope with, strip and properly cut your 12 gage wire.
o The ultimate ingredient could be the shrink wrap that will go around the whole assembly and preserve it tidy. You can expect to also require a heat gun to heat and shrink the wrap.
So, you have discovered how you can orient your batteries and the amount of you will need - now you have to operate on assembly. For this instance, we are assembling twelve battery cells - 6 down a single side and 6 down the opposite.
When you identify in which the batteries are likely in relation to your chassis And the way they're going to be laid out, you may begin. For this example, for example we are carrying out six down a person aspect and 6 down the opposite facet.
Just to make certain we are on the exact same webpage, the final word goal here is to become working wire with the optimistic terminal of the first battery for the favourable terminal on the electric RC motor then jogging a wire from the destructive terminal on the final battery in the pack for the optimistic terminal of one's other battery pack, thereby developing a accomplished circuit.
This mean you might want to have ample wire to reach from your good terminal of one's very first battery to that terminal and Similarly within the destructive to accomplish the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your initially cell to ensure constructive is pointing "upwards" and damaging is pointing "downwards" after which reverse the following battery so It really is opposite on down the road. If you purchased the battery assembly jig, This is certainly when you'd utilize it to align your cells and maintain them in place.
Adhere. Stick every one of the batteries together with your rapidly drying adhesive to They're to be able and aligned thoroughly.
Flux. Use your flux now on the relationship points.
Link - Use your battery bars to attach your cells. You'll have to heat up your soldering gun and warmth up the battery bar. Using the bar protects the battery and once the flux begins to bubble, you hire your usage of solder. The objective is to NOT warmth the battery by itself. Heating the battery is don't just counterproductive, because when you damage the battery it would not work, but also perilous because the mobile may possibly explode if overheated.
You'll be wanting to complete exactly the same measures to the remaining battery connections. You happen to be connecting the damaging to your good repeatedly again. You'll then be ready to attach wiring in your battery pack.
The wires need to be pre-tinned which suggest you have to strip off 1 / 4 inch of the protecting plastic wiring sheath, make use of the flux to clean them - utilize the flux liberally - warmth your solder gun and after that warmth the wire and movement the solder in the wire until totally saturated. You are going to also want solder within the batteries so the solder will act given that the connector with the battery.
Once the two, six cell battery packs are complete, you will need to use the shrink wrap to safe them - and you will have your entire battery pack! Now you'll be able to electricity and fly your RC helicopter, plane, boat, automobile or truck with no troubles!
