Constructing an RC Battery Pack - A Fundamental How-To
If you like RC, you recognize the value of a battery pack. The kind of batteries you select, how very well your pack is assembled And just how successfully you cost them are all vital aspects to powering your RC motor vehicle. Certain, You should buy a battery pack pre-assembled, but It's also possible to Construct your own private and get the gratification of developing and powering your own private vehicle.
The very 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'll need. You also want to think about the next:
one. Look at the chassis of one's auto. The type of auto isn't going to subject up to the level of Place where you have to maneuver. The batteries may possibly have to be oriented in the flat pack, a clustered pack or as both of those. You should also contemplate the distribution of excess weight inside your automobile - if the battery fat will probably be distributed in a facet to aspect or back to entrance fashion. In some instances your chassis Place for a battery pack will not be adaptable, so be aware of those constraints Before you begin.
two. Think about the motor powering your RC car. With regards to the power needs, you'll be able to figure out the number of batteries or cells you'll need. That is also whenever you can make your mind up the kind of batteries you can expect to use - if you wish to keep your NiMH batteries or improve to LiPo.
three. Figuring out your voltage can be a very simple issue of addition. A typical cell voltage is 1.2v, so wired inside of a sequence - 12 batteries will incorporate approximately fourteen.4v Automated Guided Vehicles (AGV) Battery - which might electrical power an fourteen.4 volt RC electric motor.
Upcoming, You will need to gather your battery pack provides - so This is a sample browsing record. Try to remember, we are assuming we are creating a battery pack with fourteen.4v, as in the instance earlier mentioned:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you may purchase battery bars in bulk if you plan to create multiple pack and save $)
o Wire: You will need a better excellent twelve gage that has a substantial strand count. This kind of wire, Using these features is going to be more versatile which is right along with staying far more efficient for electric power transmission.
o 80-one hundred Watt Soldering Gun. You'll be wanting a gun simply because you is often additional specific and faster - this is necessary because of the warmth sensitivity of batteries. The speedier plus much more particular it is possible to be, the not as likely You will be to wreck the battery.
o sixty/40 Solder. This really is bigger top quality - also important for rapid and accurate perform and steering clear of battery hurt.
o Flux. This is the chemical cleaning agent that gets rid of oxidation from metallic to aid soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying adhesive will likely be utilized to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries properly and facilitate a tidy battery pack. The batteries finish up essentially wanting like cord Wooden - tidily bundled.
o Soldering "Encouraging Arms" - optional. These devices assist you to keep matters in place Whilst you solder.
o Yet another optional timesaver is to get a "Aiding Fingers" accent to your soldering station.
o Multi Meter. You'll need a fantastic multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will help you cope with, strip and properly Minimize your 12 gage wire.
o The final part is definitely the shrink wrap that can go within the full assembly and continue to keep it tidy. You'll also require a heat gun to heat and shrink the wrap.
So, you have determined the way to orient your batteries and how many you will need - now you can get to operate on assembly. For this example, we're assembling 12 battery cells - six down one particular side and six down the opposite.
After you establish exactly where the batteries are heading in relation in your chassis And exactly how they are going being laid out, it is possible to begin. For this instance, for example we're carrying out 6 down a person facet and 6 down another facet.
Just to verify we're on the same website page, the ultimate goal Here's for being managing wire from your positive terminal of your respective initially battery for the constructive terminal on the electric RC motor after which you can functioning a wire with the damaging terminal on the last battery as part of your pack into the favourable terminal of the other battery pack, therefore making a concluded circuit.
This signify you should have ample wire to achieve with the favourable terminal of your respective initial battery to that terminal and Also through the unfavorable to finish the circuit with your other battery pack so bear that in your mind.
Orientation. Align your initial cell so that good is pointing "upwards" and adverse is pointing "downwards" and afterwards reverse another battery so It is opposite on down the line. If you purchased the battery assembly jig, this is any time you'd use it to align your cells and maintain them in place.
Adhere. Stick the many batteries together with your speedy drying adhesive to These are in order and aligned appropriately.
Flux. Make use of your flux now over the relationship factors.
Connection - Make use of your battery bars to connect your cells. You'll have to heat up your soldering gun and heat up the battery bar. Using the bar shields the battery and if the flux begins to bubble, you use your usage of solder. The target is not to heat the battery itself. Heating the battery is don't just counterproductive, because when you harm the battery it would not do the job, but in addition hazardous since the mobile may explode if overheated.
You'll want to complete precisely the same measures for your remaining battery connections. That you are connecting the unfavorable on the constructive repeatedly once more. You can then be All set to attach wiring in your battery pack.
The wires must be pre-tinned which mean you might want to strip off 1 / 4 inch on the protective plastic wiring sheath, use the flux to scrub them - implement the flux liberally - heat your solder gun and then warmth the wire and move the solder to the wire until carefully saturated. You will also want solder about the batteries so the solder will act given that the connector Together with the battery.
Once the two, six mobile battery packs are complete, you'll be wanting to employ the shrink wrap to protected them - and you'll have your full battery pack! Now you can power and fly your RC helicopter, airplane, boat, vehicle or truck without any difficulties!
