Building an RC Battery Pack - A Standard How-To
If you love RC, you recognize the importance of a battery pack. The type of batteries you select, how nicely your pack is assembled And the way proficiently you cost them are all significant areas to powering your RC motor vehicle. Absolutely sure, you can buy a battery pack pre-assembled, but It's also possible to Develop your own and get the satisfaction of coming up with and powering your own personal motor vehicle.
The very first thing you'll want to do is when you decide To place alongside one another a battery pack is what you are powering and the amount of juice you may need. You furthermore may will need to think about the subsequent:
1. Consider the chassis of your respective vehicle. The type of car or truck does not make any difference as much as the amount of space by which you have to maneuver. The batteries could have to be oriented within a flat pack, a clustered pack or as the two. You should also think about the distribution of excess weight inside your motor vehicle - whether or not the battery bodyweight will likely be distributed within a side to facet or again to entrance manner. In some instances your chassis space for just a battery pack isn't adaptable, so pay attention to Those people constraints Before you begin.
2. Consider the motor powering your RC motor vehicle. According to the electrical power necessities, you'll identify the amount of batteries or cells you require. This really is also whenever you can make your mind up the kind of batteries you'll use - in order to maintain your NiMH batteries or update to LiPo.
3. Figuring out your voltage is really a straightforward matter of addition. An ordinary cell voltage is 1.2v, so wired inside of a series - 12 batteries will incorporate as much as fourteen.4v - which would electrical power an fourteen.four volt RC electric powered motor.
Subsequent, You will need to assemble your battery pack materials - so Here is a sample procuring checklist. Don't forget, we are assuming we are making a battery pack with 14.4v, as in the instance over:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you may buy battery bars in bulk if you propose to construct multiple pack and save $)
o Wire: You'll want the next high-quality twelve gage which has a substantial strand rely. Such a wire, Using these properties will likely be additional versatile which is right along with getting far more productive for electric power transmission.
o 80-a hundred Watt Soldering Gun. You'll be wanting a gun since you is usually a lot more exact and a lot quicker - this is important as a result of warmth sensitivity of batteries. The speedier and even more specific you can be, the more unlikely You will be to wreck the battery.
o sixty/forty Solder. This is certainly higher good quality - also crucial for speedy and precise do the job and preventing battery problems.
o Flux. That is a chemical cleaning agent that removes oxidation from steel to aid soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive might be accustomed to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries thoroughly and facilitate a tidy battery pack. The batteries finish up fundamentally wanting like cord wood - tidily bundled.
o Soldering "Supporting Fingers" - optional. These units enable you to maintain matters in position As you solder.
o An additional optional timesaver is to get a "Encouraging Palms" accessory on your soldering station.
o Multi Meter. You need a fantastic multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These tools can assist you deal with, strip and adequately cut your twelve gage wire.
o The ultimate element could be the shrink wrap which will go around the overall assembly and maintain it tidy. You will also require a warmth gun to warmth and shrink the wrap.
So, you have determined how you can orient your batteries and the number of you would like - now you get to operate on assembly. For this instance, we are assembling 12 battery cells - six down a person facet and six down the opposite.
After you detect where the batteries are going in relation on your chassis And the way they're going to get laid out, you may begin. For this instance, to illustrate we are performing 6 down one side and six down another side.
Just to be sure we're on precisely the same web page, the final word aim here is to become managing wire from the optimistic terminal within your initial battery for the good terminal on the electric RC motor and then managing a wire within the damaging terminal on the final battery in the pack on the good terminal of one's other battery pack, thereby creating a accomplished circuit.
This signify you need to have adequate wire to reach through the beneficial terminal of your to start with battery to that terminal and Similarly within the unfavorable to complete the circuit together with your other battery pack so bear that in mind.
Orientation. Align your first mobile to ensure beneficial is pointing "upwards" and adverse is pointing "downwards" and after that reverse another battery so It can be opposite on down the road. If you purchased the battery assembly jig, this is whenever you'd utilize it to align your cells and keep them in position.
Adhere. Adhere each of the batteries together with your rapidly drying adhesive to They may be to be able and aligned appropriately.
Flux. Use your flux now around the link factors.
Link - Use your battery bars to connect your cells. You will need to warmth up your soldering gun and heat up the battery bar. Utilizing the bar guards the battery and in the event the flux begins to bubble, you utilize your usage of solder. The goal is to NOT heat the battery itself. Heating the battery is not simply counterproductive, since should you injury the battery it will not likely do the job, but will also dangerous as the cell could explode if overheated.
You will need to finish the same steps to the remaining battery connections. You are connecting the detrimental for the beneficial repeatedly once more. You are going to then be ready to attach wiring on your battery pack.
The wires need to be pre-tinned which necessarily mean you should strip off 1 / 4 inch from the protective plastic wiring sheath, make use of the flux to wash them - utilize the flux liberally - heat your solder gun after which you can heat the wire and flow the solder to the wire till thoroughly saturated. You are going to also want solder within the batteries Therefore the solder will act as being the connector Automated Guided Vehicles (AGV) Battery Using the battery.
When the two, six mobile battery packs are finish, you'll want to hire the shrink wrap to secure them - and you'll have your full battery pack! Now you can electrical power and fly your RC helicopter, aircraft, boat, auto or truck without complications!
