Making an RC Battery Pack - A Standard How-To
If you love RC, you are aware of the importance of a battery pack. The kind of batteries you end up picking, how properly your pack is assembled And exactly how effectively you demand them are all critical elements to powering your RC auto. Confident, you can buy a battery pack pre-assembled, but It's also possible to Construct your own personal and acquire the fulfillment of developing and powering your own personal car.
The first thing you must do is when you select to put jointly a battery pack is what you're powering and exactly how much juice you need. You furthermore mght need to consider the subsequent:
one. Consider the chassis of your vehicle. The sort of car or truck won't matter up to the level of House by which you have to maneuver. The batteries could must be oriented inside of a flat pack, a clustered pack or as both equally. You should also think of the distribution of excess weight in your car or truck - if the battery fat will probably be dispersed inside of a side to aspect or again to entrance manner. In some cases your chassis Place for any battery pack isn't adaptable, so concentrate on These constraints Before you begin.
two. Think about the motor powering your RC automobile. With regards to the electricity demands, you can figure out the number of batteries or cells you'll need. This is also whenever you can make a decision the kind of batteries you are going to use - if you'd like to keep your NiMH batteries or enhance to LiPo.
three. Deciding your voltage is really a very simple issue of addition. A normal mobile voltage is one.2v, so wired inside of a series - 12 batteries will increase as much as fourteen.4v - which would electrical power an 14.four volt RC electric powered motor.
Next, You'll have to assemble your battery pack supplies - so here's a sample searching record. Keep in mind, we are assuming we're making a battery pack with fourteen.4v, as in the example over:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you may buy battery bars in bulk if you propose to construct multiple pack and help you save $)
o Wire: You will need an increased top quality twelve gage having a superior strand rely. Such a wire, with these qualities are going to be extra adaptable which is ideal and also getting additional effective for electrical power transmission.
o 80-100 Watt Soldering Gun. You'll be wanting a gun because you may be much more specific and quicker - this is important as a result of warmth sensitivity of batteries. The quicker and much more unique you are able to be, the less likely you'll be to break the battery.
o 60/40 Solder. This is better excellent - also essential for quick and exact work and staying away from battery harm.
o Flux. This is a chemical cleaning agent that gets rid of oxidation from steel 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 together.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries adequately and aid a tidy battery pack. The batteries finish up basically searching like cord Wooden - tidily bundled.
o Soldering "Helping Arms" - optional. These equipment let you keep items set up Whilst you solder.
o One more optional timesaver is to obtain a "Helping Hands" accessory for your soldering station.
o Multi Meter. You need a superior multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These resources will help you cope with, strip and effectively Lower your twelve gage wire.
o The ultimate part would be the shrink wrap that can go throughout the whole assembly and continue to keep it tidy. You may also need a warmth gun to heat and shrink the wrap.
So, you've determined how you can orient your batteries and what number of you may need - now you receive to work on assembly. For this example, we are assembling 12 battery cells - 6 down a single aspect and six down another.
As you determine where by the batteries are going in relation in your chassis and how they're going to Automated Guided Vehicles (AGV) Battery become laid out, you are able to start off. For this example, to illustrate we're doing six down just one side and 6 down another facet.
Just to be certain we are on a similar site, the final word objective here is to get operating wire from your good terminal within your first battery towards the optimistic terminal on the electrical RC motor and afterwards functioning a wire from your negative terminal on the last battery inside your pack to the favourable terminal of one's other battery pack, therefore creating a finished circuit.
This mean you must have adequate wire to reach from your constructive terminal of your respective initial battery to that terminal and likewise in the damaging to complete the circuit with your other battery pack so bear that in mind.
Orientation. Align your first mobile to ensure optimistic is pointing "upwards" and detrimental is pointing "downwards" and after that reverse the subsequent battery so It is opposite on down the line. If you bought the battery assembly jig, This really is once you'd use it to align your cells and maintain them in place.
Adhere. Stick each of the batteries together with your rapid drying adhesive to They can be as a way and aligned properly.
Flux. Use your flux now about the link factors.
Connection - Use your battery bars to attach your cells. You will need to heat up your soldering gun and warmth up the battery bar. Using the bar protects the battery and once the flux starts to bubble, you hire your usage of solder. The intention is not to warmth the battery by itself. Heating the battery is not only counterproductive, given that if you damage the battery it won't do the job, but also perilous as the mobile may explode if overheated.
You'll be wanting to finish the exact same measures with the remaining battery connections. You're connecting the adverse to your beneficial again and again yet again. You are going to then be ready to connect wiring for your battery pack.
The wires need to be pre-tinned which signify you have to strip off 1 / 4 inch from the protective plastic wiring sheath, utilize the flux to clean them - apply the flux liberally - warmth your solder gun after which heat the wire and circulation the solder into the wire till totally saturated. You may also want solder around the batteries Hence the solder will act given that the connector Along with the battery.
When the two, 6 cell battery packs are full, you'll want to hire the shrink wrap to secure them - and you'll have your full battery pack! Now you'll ability and fly your RC helicopter, plane, boat, car or truck or truck without difficulties!
