Building an RC Battery Pack - A Standard How-To
If you love RC, you recognize the importance of a battery pack. The sort of batteries you choose, how nicely your pack is assembled And exactly how efficiently you demand them are all important factors to powering your RC vehicle. Absolutely sure, You should purchase a battery pack pre-assembled, but you can also Make your personal and have the fulfillment of creating and powering your personal car or truck.
The very first thing you have to do is when you select to put jointly a battery pack is what you are powering and exactly how much juice you require. Additionally you require to think about the subsequent:
one. Think about the chassis of the car. The type of car or truck does not make a difference about the level of Area through which you have to maneuver. The batteries may possibly must be oriented inside of a flat pack, a clustered pack or as both equally. It's also advisable to think of the distribution of body weight inside your automobile - if the battery pounds is going to be dispersed in the aspect to side or back to entrance method. Sometimes your chassis House for just a battery pack isn't adaptable, so concentrate on those constraints before you start.
two. Look at the motor powering your RC vehicle. Depending upon the energy necessities, you can decide the quantity of batteries or cells you may need. This is also when you can come to a decision the sort of batteries you may use - if you'd like to maintain your NiMH batteries or upgrade to LiPo.
3. Figuring out your voltage is mostly a simple issue of addition. A standard mobile voltage is one.2v, so wired inside of a collection - 12 batteries will insert around fourteen.4v - which might electrical power an fourteen.four volt RC electric motor.
Up coming, You will need to gather your battery pack provides - so Here is a sample searching list. Remember, we're assuming we're developing a battery pack with 14.4v, as in the example previously mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you could purchase battery bars in bulk if you intend to create more than one pack and conserve $)
o Wire: You'll want the next top quality 12 gage having a higher strand rely. This kind of wire, with these features might be a lot more adaptable which is right along with currently being a lot more productive for electrical power transmission.
o eighty-one hundred Watt Soldering Gun. You will need a gun because you is often more precise and quicker - this is essential due to warmth sensitivity of batteries. The more rapidly and much more specific you are able to be, the less likely you'll be to damage the battery.
o 60/40 Solder. This is often increased good quality - also significant for quick and correct get the job done and keeping away from battery injury.
o Flux. It is a chemical cleaning agent that removes oxidation from metallic to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying Automated Guided Vehicles (AGV) Battery adhesive will likely be accustomed to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries thoroughly and facilitate a tidy battery pack. The batteries turn out in essence seeking like cord wood - tidily bundled.
o Soldering "Aiding Palms" - optional. These units allow you to maintain things in place When you solder.
o An additional optional timesaver is to get a "Helping Hands" accessory for the soldering station.
o Multi Meter. You will need a fantastic multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will let you take care of, strip and correctly Slash your twelve gage wire.
o The ultimate part would be the shrink wrap that will go throughout the full assembly and continue to keep it tidy. You can expect to also need a warmth gun to warmth and shrink the wrap.
So, you have discovered tips on how to orient your batteries and the number of you would like - now you can get to operate on assembly. For this example, we are assembling twelve battery cells - 6 down a single side and six down the other.
When you determine exactly where the batteries are heading in relation to the chassis and how they are going to generally be laid out, you could commence. For this instance, to illustrate we are executing 6 down one facet and 6 down another facet.
Just to verify we are on the same webpage, the final word target Here's to generally be running wire in the good terminal of one's very first battery towards the constructive terminal on the electrical RC motor and afterwards managing a wire in the detrimental terminal on the last battery in the pack into the favourable terminal of your other battery pack, thereby creating a accomplished circuit.
This signify you should have enough wire to succeed in within the positive terminal of one's initial battery to that terminal and Similarly with the detrimental to accomplish the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your to start with mobile to ensure that constructive is pointing "upwards" and unfavorable is pointing "downwards" after which reverse the next battery so It truly is opposite on down the line. If you purchased the battery assembly jig, That is any time you'd utilize it to align your cells and hold them in place.
Adhere. Stick every one of the batteries along with your quickly drying adhesive to They're as a way and aligned effectively.
Flux. Use your flux now around the link details.
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 when the flux begins to bubble, you utilize your usage of solder. The target is to NOT heat the battery itself. Heating the battery is not simply counterproductive, due to the fact in the event you injury the battery it will not likely function, but also hazardous because the cell could explode if overheated.
You'll want to complete exactly the same ways for your remaining battery connections. That you are connecting the damaging to your good again and again again. You can expect to then be Completely ready to connect wiring towards your battery pack.
The wires should be pre-tinned which suggest you'll want to strip off 1 / 4 inch with the protecting plastic wiring sheath, use the flux to wash them - utilize the flux liberally - warmth your solder gun after which you can heat the wire and circulation the solder into the wire till extensively saturated. You can also want solder over the batteries And so the solder will act because the connector Along with the battery.
As soon as the two, 6 cell battery packs are entire, you'll be wanting to utilize the shrink wrap to protected them - and you will have your full battery pack! Now you'll electrical power and fly your RC helicopter, plane, boat, auto or truck without any challenges!
