Building an RC Battery Pack - A Basic How-To
If you're keen on RC, you realize the necessity of a battery pack. The sort of batteries you choose, how perfectly your pack is assembled And the way proficiently you cost them are all vital factors to powering your RC car or truck. Absolutely sure, You should buy a battery pack pre-assembled, but It's also possible to Construct your own and get the satisfaction of coming up with and powering your own private motor vehicle.
The first thing you might want to do is when you choose To place collectively a battery pack is what you are powering and how much juice you may need. You furthermore mght will need to consider the next:
1. Look at the chassis within your automobile. The sort of automobile doesn't issue approximately the level of House through which You need to maneuver. The batteries may possibly should be oriented within a flat pack, a clustered pack or as both of those. You should also take into consideration the distribution of bodyweight inside your automobile - whether the battery body weight will be distributed within a side to aspect or again to front fashion. In some cases your chassis Area to get a battery pack just isn't adaptable, so concentrate on All those constraints before you start.
two. Consider the motor powering your RC automobile. Based on the energy requirements, you'll decide the quantity of batteries or cells you'll need. That is also if you can make a decision the kind of batteries you will use - if you want to keep your NiMH batteries or improve to LiPo.
3. Pinpointing your voltage is known as a very simple make any difference of addition. An ordinary cell voltage is one.2v, so wired in a sequence - twelve batteries will include approximately 14.4v - which would power an fourteen.four volt RC electric powered motor.
Subsequent, You'll have to assemble your battery pack provides - so This is a sample searching record. Try to remember, we're assuming we are making a battery pack with fourteen.4v, as in the example above:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you may purchase battery bars in bulk if you propose to develop more than one pack and help save $)
o Wire: You'll be wanting a higher top quality twelve gage by using a significant strand rely. This kind of wire, Using these attributes will likely be much more adaptable which is good along with getting additional effective for ability transmission.
o 80-100 Watt Soldering Gun. You'll want a gun simply because you might be far more exact and a lot quicker - this is essential due to the warmth sensitivity of batteries. The speedier plus more certain it is possible to be, the less likely You will be to damage the battery.
o 60/forty Solder. This is greater excellent - also important for speedy and correct work and steering clear of battery problems.
o Flux. That 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 quickly drying adhesive is going to be accustomed to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries effectively and facilitate a tidy battery pack. The batteries turn out basically looking like wire Wooden - tidily bundled.
o Soldering "Encouraging Fingers" - optional. These gadgets help you hold items in position As you solder.
o A different optional timesaver is to obtain a "Helping Arms" accessory on your soldering station.
o Multi Meter. You will need a fantastic multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications can assist you deal with, strip and correctly cut your 12 gage wire.
o The ultimate component is the shrink wrap which can go throughout the overall assembly and retain it tidy. You Automated Guided Vehicles (AGV) Battery can also have to have a heat gun to warmth and shrink the wrap.
So, you've identified the best way to orient your batteries and the quantity of you need - now you will get to work on assembly. For this instance, we are assembling 12 battery cells - six down just one facet and 6 down the opposite.
When you finally recognize where the batteries are going in relation to the chassis And the way they're going to become laid out, it is possible to get started. For this example, as an example we are doing 6 down one particular side and six down another aspect.
Just to be certain we're on exactly the same site, the last word goal here is for being running wire from the constructive terminal of one's first battery into the positive terminal on the electric RC motor then jogging a wire from your adverse terminal on the last battery as part of your pack into the good terminal within your other battery pack, therefore making a concluded circuit.
This indicate you should have enough wire to succeed in from your favourable terminal of your respective very first battery to that terminal and likewise in the destructive to finish the circuit with your other battery pack so bear that in mind.
Orientation. Align your initial cell so that beneficial is pointing "upwards" and detrimental is pointing "downwards" and afterwards reverse the next battery so It can be opposite on down the line. If you purchased the battery assembly jig, This is certainly when you'd use it to align your cells and hold them in place.
Adhere. Adhere many of the batteries along with your quickly drying adhesive to These are as a way and aligned appropriately.
Flux. Make use of your flux now over the connection points.
Link - Use your battery bars to connect your cells. You'll have to warmth up your soldering gun and heat up the battery bar. Utilizing the bar safeguards the battery and once the flux starts to bubble, you employ your usage of solder. The target is not to warmth the battery by itself. Heating the battery is not just counterproductive, considering that in case you destruction the battery it would not function, but also unsafe as the cell may possibly explode if overheated.
You will need to finish a similar methods for that remaining battery connections. You happen to be connecting the adverse on the constructive time and again once more. You may then be Prepared to connect wiring to the battery pack.
The wires should be pre-tinned which signify you must strip off a quarter inch of your protecting plastic wiring sheath, utilize the flux to clean them - use the flux liberally - warmth your solder gun after which heat the wire and circulation the solder in to the wire until carefully saturated. You can expect to also want solder over the batteries And so the solder will act as the connector Along with the battery.
When the two, 6 cell battery packs are complete, you'll want to employ the shrink wrap to secure them - and you will have your entire battery pack! Now you'll be able to energy and fly your RC helicopter, airplane, boat, car or truck without any issues!
