Constructing an RC Battery Pack - A Standard How-To
If you like RC, you know the value of a battery pack. The type of batteries you choose, how nicely your pack is assembled And just how successfully you cost them are all crucial areas to powering your RC auto. Certain, You should buy a battery pack pre-assembled, but You may as well Create your personal and obtain the fulfillment of developing and powering your very own motor vehicle.
The very first thing you need to do is when you select To place together a battery pack is what you are powering and just how much juice you need. In addition, you want to consider the following:
one. Think about the chassis within your vehicle. The type of vehicle isn't going to make a difference as much as the quantity of House in which You will need to maneuver. The batteries might must be oriented within a flat pack, a clustered pack or as both equally. You should also contemplate the distribution of excess weight in the auto - if the battery fat will be distributed in a side to aspect or back again to entrance way. In some cases your chassis space for your battery pack is not adaptable, so know about those constraints Before you begin.
2. Think about the motor powering your RC car. According to the ability specifications, you can determine the quantity of batteries or cells you would like. This is often also whenever you can determine the sort of batteries you may use - if you want to keep the NiMH batteries or update to LiPo.
3. Analyzing your voltage is really a very simple make a difference of addition. An ordinary mobile voltage is one.2v, so wired inside a collection - 12 batteries will incorporate approximately fourteen.4v - which might electrical power an 14.4 volt RC electrical motor.
Up coming, You will need to collect your battery pack materials - so here's a sample buying checklist. Don't forget, we're assuming we're developing a battery pack with fourteen.4v, as in the example higher than:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you'll be able to buy battery bars in bulk if you intend to develop more than one pack and help save $)
o Wire: You'll want a higher excellent twelve gage having a large strand count. This sort of wire, Using these qualities will probably be far more versatile which is right and remaining extra productive for ability transmission.
o 80-one hundred Watt Soldering Gun. You'll be wanting a gun simply because you may be a lot more specific and more rapidly - this is critical due to the warmth sensitivity of batteries. The speedier and a lot more specific it is possible to be, the more unlikely you'll be to damage the battery.
o sixty/forty Solder. This is increased top quality - also crucial for fast and correct perform and staying away from battery destruction.
o Automated Guided Vehicles (AGV) Battery Flux. It is a chemical cleansing agent that gets rid of oxidation from metallic to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive is going to be accustomed to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries appropriately and facilitate a tidy battery pack. The batteries turn out fundamentally seeking like wire Wooden - tidily bundled.
o Soldering "Aiding Arms" - optional. These devices enable you to keep issues in position As you solder.
o One more optional timesaver is to get a "Encouraging Fingers" accent for your personal soldering station.
o Multi Meter. You'll need a good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These instruments can assist you cope with, strip and thoroughly Slice your 12 gage wire.
o The final ingredient could be the shrink wrap that will go throughout the total assembly and retain it tidy. You'll also need a warmth gun to warmth and shrink the wrap.
So, you've recognized tips on how to orient your batteries and the quantity of you require - now you have to work on assembly. For this instance, we are assembling 12 battery cells - six down one aspect and 6 down the other.
After you establish the place the batteries are heading in relation towards your chassis And exactly how they're going for being laid out, you can start off. For this example, let's say we're performing six down a person facet and six down the other facet.
Just to verify we're on the same page, the ultimate aim here is to be operating wire from your beneficial terminal of your initially battery towards the positive terminal on the electric RC motor after which managing a wire through the destructive terminal on the last battery in your pack on the positive terminal of your respective other battery pack, therefore creating a accomplished circuit.
This signify you have to have ample wire to reach from your constructive terminal of your first battery to that terminal and Also through the unfavorable to finish the circuit with the other battery pack so bear that in mind.
Orientation. Align your first mobile to make sure that positive is pointing "upwards" and unfavorable is pointing "downwards" after which you can reverse the next battery so It can be opposite on down the line. If you purchased the battery assembly jig, this is once you'd utilize it to align your cells and keep them in place.
Adhere. Stick the many batteries together with your quickly drying adhesive to They're in order and aligned effectively.
Flux. Use your flux now to the connection points.
Connection - Use your battery bars to attach your cells. You'll need to heat up your soldering gun and heat up the battery bar. Using the bar guards the battery and if the flux starts to bubble, you make use of your use of solder. The objective is to NOT heat the battery alone. Heating the battery is not simply counterproductive, since in the event you harm the battery it will not function, and also harmful since the cell may explode if overheated.
You'll want to complete the identical measures for your remaining battery connections. You're connecting the detrimental to the good time and again all over again. You'll then be Completely ready to connect wiring to your battery pack.
The wires need to be pre-tinned which signify you'll want to strip off 1 / 4 inch from the protective plastic wiring sheath, use the flux to wash them - implement the flux liberally - heat your solder gun after which warmth the wire and move the solder into your wire right until totally saturated. You can also want solder on the batteries And so the solder will act given that the connector While using the battery.
After the two, 6 cell battery packs are entire, you'll be wanting to use the shrink wrap to protected them - and you'll have your entire battery pack! Now you'll be able to electrical power and fly your RC helicopter, airplane, boat, vehicle or truck with no challenges!
