Building an RC Battery Pack - A Essential How-To
If you love RC, you understand the necessity of a battery pack. The kind of batteries you choose, how effectively your pack is assembled And exactly how proficiently you demand them are all crucial features to powering your RC vehicle. Sure, You should buy a battery pack pre-assembled, but It's also possible to build your own private and obtain the gratification of designing and powering your individual car or truck.
The very first thing you should do is when you choose To place with each other a battery pack is what you're powering and the amount of juice you will need. You furthermore may have to have to consider the next:
one. Consider the chassis of the car. The type Automated Guided Vehicles (AGV) Battery of car would not matter approximately the level of Area by which you have to maneuver. The batteries might must be oriented inside of a flat pack, a clustered pack or as both of those. It's also wise to take into consideration the distribution of pounds inside your motor vehicle - if the battery fat will likely be distributed in a side to facet or back again to entrance fashion. In some cases your chassis Place for your battery pack is not adaptable, so know about All those constraints Before you begin.
two. Look at the motor powering your RC motor vehicle. According to the electric power requirements, you'll be able to ascertain how many batteries or cells you'll need. This is certainly also if you can determine the kind of batteries you can expect to use - if you want to keep your NiMH batteries or enhance to LiPo.
three. Figuring out your voltage is really a easy make any difference of addition. A typical mobile voltage is 1.2v, so wired within a collection - 12 batteries will incorporate approximately 14.4v - which would electric power an fourteen.four volt RC electric powered motor.
Subsequent, You'll have to collect your battery pack materials - so This is a sample shopping record. Remember, we are assuming we're making a battery pack with 14.4v, as in the instance earlier mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you'll be able to get battery bars in bulk if you intend to build more than one pack and preserve $)
o Wire: You'll be wanting an increased high quality 12 gage by using a significant strand rely. This kind of wire, with these features will be a lot more adaptable which is ideal along with getting a lot more effective for ability transmission.
o 80-a hundred Watt Soldering Gun. You'll want a gun because you might be extra correct and faster - this is important as a result of heat sensitivity of batteries. The more quickly and a lot more distinct you may be, the more unlikely You will be to break the battery.
o 60/40 Solder. This really is increased good quality - also important for swift and correct work and averting battery damage.
o Flux. This can be a chemical cleansing agent that eliminates oxidation from metal to facilitate soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive will likely be accustomed to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries appropriately and facilitate a tidy battery pack. The batteries end up generally seeking like cord wood - tidily bundled.
o Soldering "Encouraging Hands" - optional. These products enable you to hold matters set up As you solder.
o A different optional timesaver is to obtain a "Helping Fingers" accessory in your soldering station.
o Multi Meter. You need a great multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will assist you to manage, strip and effectively Minimize your 12 gage wire.
o The final element could be the shrink wrap which will go within the overall assembly and preserve it tidy. You can expect to also require a heat gun to warmth and shrink the wrap.
So, you've recognized the best way to orient your batteries and what number of you would like - now you will get to work on assembly. For this example, we're assembling 12 battery cells - 6 down one aspect and six down another.
When you establish where by the batteries are likely in relation towards your chassis And exactly how they are going to generally be laid out, you may start. For this example, as an example we are accomplishing 6 down a single aspect and 6 down another aspect.
Just to be certain we are on the identical site, the ultimate goal here is to get running wire with the positive terminal of the very first battery for the constructive terminal on the electrical RC motor after which you can functioning a wire in the destructive terminal on the final battery with your pack to your constructive terminal of your respective other battery pack, therefore making a accomplished circuit.
This signify you'll want to have ample wire to succeed in within the positive terminal of your respective initial battery to that terminal and Similarly from the adverse to accomplish the circuit with all your other battery pack so bear that in your mind.
Orientation. Align your to start with mobile so that favourable is pointing "upwards" and damaging is pointing "downwards" after which reverse the following battery so It can be opposite on down the road. If you bought the battery assembly jig, This can be if you'd use it to align your cells and hold them set up.
Adhere. Stick the many batteries along with your rapidly drying adhesive to These are to be able and aligned adequately.
Flux. Use your flux now within the connection details.
Connection - Use your battery bars to attach your cells. You will need to heat up your soldering gun and heat up the battery bar. Using the bar shields the battery and if the flux starts to bubble, you make use of your use of solder. The goal is to NOT heat the battery itself. Heating the battery is not just counterproductive, since should you hurt the battery it will not likely function, but in addition perilous as the cell may explode if overheated.
You will need to finish exactly the same ways for your remaining battery connections. You're connecting the adverse to the optimistic time and again again. You may then be Prepared to connect wiring to the battery pack.
The wires have to be pre-tinned which suggest you should strip off 1 / 4 inch on the protecting plastic wiring sheath, utilize the flux to clean them - use the flux liberally - heat your solder gun and then warmth the wire and circulation the solder into the wire until eventually comprehensively saturated. You may also want solder over the batteries And so the solder will act since the connector with the battery.
When the two, 6 cell battery packs are entire, you'll be wanting to employ the shrink wrap to safe them - and you will have your total battery pack! Now you can power and fly your RC helicopter, aircraft, boat, motor vehicle or truck without having complications!
