Building an RC Battery Pack - A Standard How-To
If you love RC, you know the value of a battery pack. The type of batteries you decide on, how effectively your pack is assembled And the way successfully you cost them are all critical features to powering your RC vehicle. Confident, You should purchase a battery pack pre-assembled, but It's also possible to Construct your own private and acquire the satisfaction of building and powering your own private automobile.
The first thing you need to do is when you decide to put jointly a battery pack is what you're powering and exactly how much juice you need. You also want to think about the subsequent:
1. Look at the chassis of the vehicle. The sort of car won't make any difference approximately the amount of Room during which You should maneuver. The batteries may possibly should be oriented in a very flat pack, a clustered pack or as both. It's also wise to think about the distribution of excess weight as part of your motor vehicle - whether or not the battery fat is going to be distributed in the aspect to facet or back again to entrance method. Sometimes your chassis Place for your battery pack isn't adaptable, so be familiar with All those constraints before you start.
two. Look at the motor powering your RC auto. Depending on the ability demands, you'll decide how many batteries or cells you need. This really is also when you can choose the type of batteries you'll use - if you want to maintain your NiMH batteries or update to LiPo.
three. Pinpointing your voltage is known as a basic make a difference of addition. A standard mobile voltage is one.2v, so wired in a sequence - 12 batteries will increase as many as fourteen.4v - which would energy an 14.4 volt RC electric powered motor.
Following, You'll have to gather your battery pack provides - so This is a sample searching checklist. Recall, we are assuming we're creating a battery pack with fourteen.4v, as in the instance over:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you could get battery bars in bulk if you plan to make multiple pack and save $)
o Wire: You'll want an increased quality 12 gage having a higher strand rely. This sort of wire, with these properties will be much more adaptable which is right together with currently being extra efficient for ability transmission.
o 80-100 Watt Soldering Gun. You'll be wanting a gun as you can be far more specific and more rapidly - this is important due to the heat sensitivity of batteries. The quicker and much more specific you'll be able to be, the more unlikely you'll be to break the battery.
o 60/40 Solder. This is greater excellent - also vital for fast and precise function and steering clear of battery damage.
o Flux. It is a chemical cleaning agent that gets rid of oxidation from metal to facilitate soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive might be utilized to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries appropriately and facilitate a tidy battery pack. The batteries finish up fundamentally hunting like wire Wooden - tidily bundled.
o Soldering "Assisting Palms" - optional. These devices permit you to hold items in position When you solder.
o Another optional timesaver is to acquire a "Supporting Palms" accent for the soldering station.
o Multi Meter. You need a fantastic multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will assist you to handle, strip and correctly Minimize your twelve gage wire.
o The ultimate part may be the shrink wrap which is able to go within the overall assembly and preserve it tidy. You are going to also need a warmth gun to warmth and shrink the wrap.
So, you've discovered ways to orient your batteries and how many you'll need - now you will get to operate on assembly. For this example, we're assembling Automated Guided Vehicles (AGV) Battery 12 battery cells - 6 down 1 aspect and 6 down another.
As soon as you establish in which the batteries are going in relation to the chassis And just how they're going to be laid out, you are able to get started. For this instance, as an instance we are accomplishing six down one side and six down one other side.
Just to make certain we are on the same site, the ultimate purpose Here's to be operating wire with the optimistic terminal within your 1st battery on the good terminal on the electrical RC motor and then operating a wire from the unfavorable terminal on the last battery as part of your pack on the optimistic terminal of the other battery pack, thus developing a accomplished circuit.
This necessarily mean you have to have ample wire to achieve through the positive terminal of your respective 1st battery to that terminal and Also through the detrimental to complete the circuit using your other battery pack so bear that in your mind.
Orientation. Align your to start with mobile to ensure that beneficial is pointing "upwards" and destructive is pointing "downwards" and then reverse the subsequent battery so It is really opposite on down the road. If you bought the battery assembly jig, That is any time you'd utilize it to align your cells and hold them in position.
Adhere. Stick each of the batteries along with your quickly drying adhesive to They're if you want and aligned thoroughly.
Flux. Use your flux now within the link details.
Link - Make use of your battery bars to connect your cells. You will need to warmth up your soldering gun and warmth up the battery bar. Utilizing the bar guards the battery and when the flux starts to bubble, you make use of your usage of solder. The target is not to warmth the battery itself. Heating the battery is don't just counterproductive, considering that if you harm the battery it won't perform, but also hazardous because the cell may explode if overheated.
You'll be wanting to accomplish the exact same actions to the remaining battery connections. You might be connecting the unfavorable into the favourable time and again once again. You can expect to then be ready to connect wiring on your battery pack.
The wires need to be pre-tinned which suggest you should strip off 1 / 4 inch of the protecting plastic wiring sheath, use the flux to scrub them - utilize the flux liberally - heat your solder gun after which heat the wire and stream the solder into the wire right until thoroughly saturated. You will also want solder about the batteries Therefore the solder will act because the connector While using the battery.
Once the two, 6 cell battery packs are comprehensive, you'll be wanting to hire the shrink wrap to protected them - and you will have your full battery pack! Now you can ability and fly your RC helicopter, plane, boat, vehicle or truck without any troubles!
