Making an RC Battery Pack - A Standard How-To
If you love RC, you understand the significance of a battery pack. The sort of batteries you choose, how properly your pack is assembled And exactly how competently you demand them are all significant facets to powering your RC car. Sure, You should buy a battery pack pre-assembled, but You may also Make your own private and acquire the gratification of developing and powering your personal automobile.
The first thing you need to do is when you decide to put alongside one another a battery pack is what you're powering and simply how much juice you will need. In addition, you need to think about the following:
one. Think about the chassis of one's motor vehicle. The type of car or truck won't issue around the quantity of Area during which You should maneuver. The batteries might should be oriented inside a flat pack, a clustered pack or as equally. It's also wise to contemplate the distribution of bodyweight within your car or truck - whether the battery bodyweight will probably be dispersed in the facet to aspect or back to front method. In some cases your chassis House for just a battery pack just isn't adaptable, so concentrate on Individuals constraints Before you begin.
2. Consider the motor powering your RC car or truck. Depending on the electric power demands, you'll decide what number of batteries or cells you need. This really is also any time you can come to a decision the type of batteries you can use - if you need to keep the NiMH batteries or up grade to LiPo.
3. Pinpointing your voltage is known as a simple make any difference of addition. An ordinary cell voltage is 1.2v, so wired in a series - twelve batteries will include around fourteen.4v - which would power an fourteen.four volt RC electrical motor.
Following, you'll need to assemble your battery pack materials - so Here is a sample procuring record. Bear in mind, we are assuming we're creating a battery pack with 14.4v, as in the example above:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you'll be able to order battery bars in bulk if you plan to develop multiple pack and save $)
o Wire: You'll be wanting an increased top quality 12 gage using a significant strand count. This kind of wire, Using these features are going to be more flexible which is good in addition to being extra efficient for power transmission.
o 80-one hundred Watt Soldering Gun. You will need a gun as you is usually far more exact and a lot quicker - this is important due to heat sensitivity of batteries. The more rapidly and more precise you'll be able to be, the not as likely you'll be to break the battery.
o 60/forty Solder. This is greater high quality - also vital for rapid and correct function and preventing battery harm.
o Flux. This is the chemical cleaning agent that removes oxidation from metallic to aid soldering. You can utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapid drying adhesive will likely be accustomed to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries correctly and facilitate a tidy battery pack. The batteries find yourself generally hunting like cord Wooden - tidily bundled.
o Soldering "Assisting Palms" - optional. These products permit you to maintain points in position As you solder.
o An additional optional timesaver is to get a "Helping Palms" accent for the soldering station.
o Multi Meter. You need a great multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These equipment can assist you take care of, strip and effectively Lower your twelve gage wire.
o The final element is definitely the shrink wrap which can go throughout the full assembly and hold it tidy. You can also require a heat gun to warmth and shrink the wrap.
So, you've identified tips on how to orient your batteries and what number of you require - now you will get to work on assembly. For this instance, we're assembling twelve battery cells - 6 down one facet and six down one other.
As you detect where the batteries are likely in relation to the chassis And the way they're going to generally be laid out, you are able to start off. For this instance, for example we're doing six down one particular facet and 6 down one other side.
Just to make sure we are on a similar site, the last word goal Here's to become operating wire within the optimistic terminal within your to start with battery on the favourable terminal on the electrical RC motor then managing a wire through the unfavorable terminal on the last battery inside your pack for the positive terminal within your other battery pack, thereby making a concluded circuit.
This suggest you need to have ample wire to achieve from the good terminal of your respective very first battery to that terminal and likewise in the damaging to finish the circuit with the other battery pack so bear that in your mind.
Orientation. Align your initially cell to ensure that beneficial is pointing "upwards" and adverse is pointing "downwards" after which reverse the next battery so it's reverse on down the line. If you bought the battery assembly jig, That is when Automated Guided Vehicles (AGV) Battery you'd utilize it to align your cells and hold them set up.
Adhere. Adhere all of the batteries along with your speedy drying adhesive to These are in order and aligned properly.
Flux. Make use of your flux now over the link details.
Link - Make use of your battery bars to connect your cells. You'll need to heat up your soldering gun and warmth up the battery bar. Utilizing the bar safeguards the battery and when the flux begins to bubble, you employ your utilization of solder. The intention is to NOT heat the battery itself. Heating the battery is not simply counterproductive, due to the fact in case you harm the battery it would not work, but also unsafe because the mobile could explode if overheated.
You will need to finish exactly the same methods with the remaining battery connections. That you are connecting the adverse to your optimistic time and again all over again. You may then be ready to connect wiring to the battery pack.
The wires need to be pre-tinned which mean you must strip off 1 / 4 inch with the protecting plastic wiring sheath, make use of the flux to clean them - use the flux liberally - warmth your solder gun and after that heat the wire and flow the solder in to the wire until finally carefully saturated. You'll also want solder about the batteries Hence the solder will act given that the connector Along with the battery.
As soon as the two, six cell battery packs are comprehensive, you'll be wanting to make use of the shrink wrap to secure them - and you will have your finish battery pack! Now you'll be able to electricity and fly your RC helicopter, airplane, boat, vehicle or truck without having issues!
