Creating an RC Battery Pack - A Basic How-To
If you like RC, you realize the value of a battery pack. The kind of batteries you select, how properly your pack is assembled And just how effectively you cost them are all essential facets to powering your RC motor vehicle. Confident, You should purchase a battery pack pre-assembled, but you can also Develop your very own and acquire the fulfillment of planning and powering your very own car.
The very first thing you need to do is when you decide To place alongside one another a battery pack is Automated Guided Vehicles (AGV) Battery what you are powering and simply how much juice you will need. Additionally you will need to think about the following:
one. Consider the chassis of your respective automobile. The kind of automobile isn't going to make any difference just as much as the quantity of Place in which you have to maneuver. The batteries may possibly need to be oriented in the flat pack, a clustered pack or as both equally. It's also advisable to contemplate the distribution of pounds with your car - if the battery fat will be dispersed in the aspect to facet or back to entrance way. In some cases your chassis Area for any battery pack just isn't adaptable, so pay attention to those constraints Before you begin.
two. Look at the motor powering your RC car or truck. According to the energy needs, you'll be able to establish the number of batteries or cells you'll need. This is certainly also any time you can come to a decision the sort of batteries you may use - if you need to keep your NiMH batteries or enhance to LiPo.
3. Figuring out your voltage is known as a uncomplicated matter of addition. A standard mobile voltage is one.2v, so wired inside of a collection - twelve batteries will include approximately 14.4v - which might electricity an fourteen.four volt RC electric powered motor.
Upcoming, You will need to gather your battery pack supplies - so here's a sample buying list. Remember, we're assuming we're developing a battery pack with 14.4v, as in the instance above:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you could purchase battery bars in bulk if you plan to make multiple pack and help save $)
o Wire: You'll be wanting a better quality twelve gage having a substantial strand rely. This type of wire, with these properties might be additional versatile which is good and remaining far more productive for ability transmission.
o eighty-one hundred Watt Soldering Gun. You'll be wanting a gun because you might be much more exact and quicker - this is important due to heat sensitivity of batteries. The speedier plus more particular you can be, the not as likely You will be to damage the battery.
o 60/40 Solder. That is larger high quality - also important for speedy and precise do the job and steering clear of battery destruction.
o Flux. It is a chemical cleansing agent that gets rid of oxidation from metallic to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive will be used to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries properly and aid a tidy battery pack. The batteries finish up essentially wanting like cord Wooden - tidily bundled.
o Soldering "Aiding Palms" - optional. These equipment allow you to keep issues in place Whilst you solder.
o Yet another optional timesaver is to get a "Assisting Fingers" accent to your soldering station.
o Multi Meter. You'll need a great multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will allow you to tackle, strip and thoroughly Minimize your twelve gage wire.
o The ultimate part could be the shrink wrap which is able to go around the entire assembly and preserve it tidy. You'll also require a warmth gun to warmth and shrink the wrap.
So, you have discovered how to orient your batteries and the amount of you'll need - now you have to work on assembly. For this instance, we're assembling 12 battery cells - six down a person aspect and six down another.
After you detect exactly where the batteries are heading in relation in your chassis and how they're going to generally be laid out, you can get started. For this instance, for instance we're performing six down a person facet and six down the other side.
Just to be certain we're on precisely the same site, the final word aim here is to become operating wire from the constructive terminal of your to start with battery to your beneficial terminal on the electrical RC motor and afterwards running a wire in the detrimental terminal on the final battery in your pack to the positive terminal of one's other battery pack, thereby creating a finished circuit.
This suggest you have to have ample wire to reach from your favourable terminal of your respective initial battery to that terminal and Similarly through the adverse to accomplish the circuit with the other battery pack so bear that in your mind.
Orientation. Align your 1st cell to make sure that beneficial is pointing "upwards" and unfavorable is pointing "downwards" then reverse the subsequent battery so It is opposite on down the road. If you bought the battery assembly jig, This can be if you'd utilize it to align your cells and hold them in position.
Adhere. Stick every one of the batteries together with your speedy drying adhesive to These are if you want and aligned correctly.
Flux. Use your flux now to the connection points.
Link - Use your battery bars to connect your cells. You will need to heat up your soldering gun and warmth up the battery bar. Utilizing the bar safeguards the battery and in the event the flux starts to bubble, you utilize your usage of solder. The target is not to heat the battery itself. Heating the battery is don't just counterproductive, due to the fact for those who injury the battery it will never work, and also dangerous as the mobile could possibly explode if overheated.
You will need to finish a similar methods for the remaining battery connections. You're connecting the damaging towards the positive repeatedly once again. You will then be All set to attach wiring for your battery pack.
The wires need to be pre-tinned which indicate you need to strip off 1 / 4 inch on the protective plastic wiring sheath, utilize the flux to scrub them - use the flux liberally - warmth your solder gun and afterwards warmth the wire and flow the solder in to the wire until finally completely saturated. You are going to also want solder to the batteries And so the solder will act given that the connector Along with the battery.
Once the two, six cell battery packs are finish, you'll want to utilize the shrink wrap to secure them - and you'll have your full battery pack! Now you can electrical power and fly your RC helicopter, airplane, boat, auto or truck without having issues!
