Constructing an RC Battery Pack - A Basic How-To
If you're keen on RC, you understand the importance of a battery pack. The sort of batteries you choose, how very well your pack is assembled And exactly how successfully you charge them are all significant facets to powering your RC car. Sure, You should buy a battery pack pre-assembled, but you can also Establish your own private and have the pleasure of coming up with and powering your own private car or truck.
The very first thing you should do is when you select to put together a battery pack is what you are powering and the amount juice you would like. You also want to think about the subsequent:
one. Look at the chassis within your motor vehicle. The sort of car does not make any difference about the amount of Place wherein you have to maneuver. The batteries may must be oriented in a flat pack, a clustered pack or as both of those. You should also consider the distribution of body weight in your vehicle - whether or not the battery pounds is going to be dispersed in the facet to facet or back to entrance fashion. In some cases your chassis space for your battery pack is not adaptable, so be familiar with These constraints Before you begin.
2. Consider the motor powering your RC vehicle. Depending upon the electrical power demands, you'll be able to determine how many batteries or cells you may need. This is certainly also after you can make your mind up the type of batteries you will use - if you would like keep the NiMH batteries or improve to LiPo.
3. Deciding your voltage is really a basic subject of addition. A standard mobile voltage is 1.2v, so wired in a very collection - 12 batteries will incorporate as many as 14.4v - which might energy an 14.4 volt RC electric motor.
Subsequent, You will need to gather your battery pack materials - so This is a sample searching list. Remember, we're assuming we are developing a battery pack with fourteen.4v, as in the example higher than:
o twelve Batteries or Battery Cells
o twelve Battery Bars (it is possible to get battery bars in bulk if you intend to make multiple pack and save $)
o Wire: You'll want the next high quality 12 gage by using a superior strand rely. This kind of wire, Using these characteristics are going to be additional versatile which is right and currently being much more efficient for electrical power transmission.
o eighty-one hundred Watt Soldering Gun. You'll be wanting a gun because you is usually additional specific and more rapidly - this is critical due to heat sensitivity of batteries. The more quickly and even more particular you can be, the less likely you'll be to wreck the battery.
o sixty/forty Solder. This really is increased quality - also vital for speedy and exact perform and staying away from battery destruction.
o Flux. This is the chemical cleaning agent that gets rid of oxidation from steel to facilitate soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapid drying adhesive will likely be utilized to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries thoroughly and aid a tidy battery pack. The batteries wind up essentially seeking like wire Wooden - tidily bundled.
o Soldering "Supporting Palms" - optional. These products let you keep factors in place while you solder.
o Yet another optional timesaver is to obtain a "Serving to Fingers" accessory for the soldering station.
o Multi Meter. You'll need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will assist you to tackle, strip and properly Reduce your 12 gage wire.
o The ultimate part may be the shrink wrap that will go within the whole assembly and maintain it tidy. You can also require a heat gun to heat and shrink the wrap.
So, you've got determined how you can orient your batteries and the amount of you need - now you get to work on assembly. For this example, we are assembling 12 battery cells - six down one particular side and 6 down the opposite.
Once you establish exactly where the batteries are likely in relation on your chassis And just how they are going to become laid out, you may start out. For this instance, for instance we're accomplishing 6 down just one side and 6 down one other aspect.
Just to verify we are on the same web site, the last word target Here's to get running wire from the positive terminal of your initial battery for the good terminal on the electrical RC motor after which managing a wire in the detrimental terminal on the final battery within your pack on the constructive terminal of the other battery pack, thus developing a finished circuit.
This indicate you must have adequate wire to reach through the beneficial terminal of your respective initial battery to that terminal and Also from your damaging to accomplish the circuit with the other battery pack so bear that in your mind.
Orientation. Align your first mobile to make sure that constructive is pointing "upwards" and destructive is pointing "downwards" and then reverse the subsequent battery so It truly is opposite on down the road. If you bought the battery assembly jig, This is often any time you'd use it to align your cells and hold them in position.
Adhere. Stick every one of the batteries along with your quickly drying adhesive to they are to be able and aligned appropriately.
Flux. Make use of your flux now about the link factors.
Relationship - Make use of your battery bars to attach your cells. You'll need to heat up your Automated Guided Vehicles (AGV) Battery soldering gun and heat up the battery bar. Utilizing the bar protects the battery and in the event the flux begins to bubble, you hire your usage of solder. The target is not to heat the battery itself. Heating the battery is don't just counterproductive, because in case you destruction the battery it will not function, but also dangerous as the cell may explode if overheated.
You'll be wanting to accomplish the same steps with the remaining battery connections. You might be connecting the damaging to your constructive again and again once more. You may then be Completely ready to attach wiring for your battery pack.
The wires have to be pre-tinned which necessarily mean you should strip off 1 / 4 inch of the protecting plastic wiring sheath, use the flux to clean them - implement the flux liberally - warmth your solder gun and then warmth the wire and circulation the solder in the wire until eventually comprehensively saturated. You are going to also want solder around the batteries And so the solder will act because the connector Together with the battery.
As soon as the two, 6 cell battery packs are comprehensive, you'll be wanting to hire the shrink wrap to safe them - and you will have your comprehensive battery pack! Now you can electricity and fly your RC helicopter, plane, boat, car or truck without having issues!
