Constructing an RC Battery Pack - A Primary How-To
If you like RC, you realize the value of a battery pack. The sort of batteries you decide on, how perfectly your pack is assembled And just how competently you demand them are all crucial features to powering your RC car. Sure, You should buy a battery pack pre-assembled, but You may as well Establish your individual and have the gratification of developing and powering your own private car.
The first thing you should do is when you select to put together a battery pack is what you're powering and the amount juice you will need. Additionally you want to consider the following:
1. Think about the chassis of one's car or truck. The kind of automobile won't matter around the level of Place where You need to maneuver. The batteries may should be oriented inside of a flat pack, a clustered pack or as Automated Guided Vehicles (AGV) Battery both of those. It's also wise to take into consideration the distribution of weight in the automobile - whether or not the battery excess weight is going to be distributed inside of a facet to side or back to front method. In some instances your chassis space for any battery pack isn't adaptable, so pay attention to those constraints Before you begin.
2. Think about the motor powering your RC car or truck. Depending upon the electricity necessities, you'll be able to identify the quantity of batteries or cells you would like. This is often also if you can choose the type of batteries you can use - if you want to maintain your NiMH batteries or enhance to LiPo.
3. Deciding your voltage is mostly a basic subject of addition. A standard mobile voltage is one.2v, so wired within a sequence - 12 batteries will insert as many as 14.4v - which might energy an 14.4 volt RC electric motor.
Following, you'll need to collect your battery pack supplies - so Here is a sample procuring list. Remember, we are assuming we are creating a battery pack with fourteen.4v, as in the instance higher than:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you'll be able to get battery bars in bulk if you propose to build multiple pack and save $)
o Wire: You'll be wanting a greater excellent twelve gage using a high strand rely. This sort of wire, with these characteristics is going to be more flexible which is good and also getting much more successful for electric power transmission.
o eighty-100 Watt Soldering Gun. You'll want a gun because you is often a lot more specific and a lot quicker - this is essential due to the heat sensitivity of batteries. The quicker and much more certain you'll be able to be, the more unlikely you'll be to break the battery.
o sixty/forty Solder. This is often increased quality - also critical for fast and accurate do the job and averting battery problems.
o Flux. This is the chemical cleaning agent that eliminates oxidation from metal to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive will likely be used to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries appropriately and aid a tidy battery pack. The batteries finish up fundamentally wanting like wire wood - tidily bundled.
o Soldering "Supporting Palms" - optional. These equipment permit you to hold items in place As you solder.
o Yet another optional timesaver is to get a "Supporting Arms" accent to your soldering station.
o Multi Meter. You need a fantastic multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These resources can assist you deal with, strip and thoroughly Slice your twelve gage wire.
o The final component may be the shrink wrap that can go around the whole assembly and retain it tidy. You may also have to have a heat gun to warmth and shrink the wrap.
So, you've identified tips on how to orient your batteries and what number of you would like - now you receive to work on assembly. For this example, we're assembling twelve battery cells - six down one side and six down another.
Once you detect where the batteries are going in relation to the chassis And the way they're going to be laid out, you may begin. For this instance, as an example we're undertaking six down one particular facet and six down one other side.
Just to verify we are on the same webpage, the last word goal here is for being jogging wire in the positive terminal of your initially battery on the good terminal on the electrical RC motor after which jogging a wire within the damaging terminal on the last battery in your pack to the beneficial terminal of your other battery pack, thereby creating a done circuit.
This indicate you have to have sufficient wire to achieve from your beneficial terminal of the first battery to that terminal and Furthermore with the adverse to finish the circuit with all your other battery pack so bear that in mind.
Orientation. Align your initial mobile to make sure that beneficial is pointing "upwards" and unfavorable is pointing "downwards" after which reverse the following 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 keep them in position.
Adhere. Stick all of the batteries together with your rapidly drying adhesive to They are really to be able and aligned properly.
Flux. Use your flux now about the connection points.
Connection - Make use of your battery bars to attach your cells. You'll need to heat up your soldering gun and warmth up the battery bar. Using the bar shields the battery and if the flux begins to bubble, you use your use of solder. The purpose is not to warmth the battery itself. Heating the battery is not just counterproductive, since for those who damage the battery it is not going to function, but in addition unsafe because the cell may well explode if overheated.
You'll be wanting to accomplish the identical methods for the remaining battery connections. You are connecting the damaging to the good time and again once again. You'll then be ready to attach wiring for your battery pack.
The wires have to be pre-tinned which indicate you'll want to strip off a quarter inch on the protecting plastic wiring sheath, use the flux to wash them - utilize the flux liberally - heat your solder gun and afterwards heat the wire and circulation the solder into your wire till thoroughly saturated. You can expect to also want solder on the batteries so the solder will act as being the connector While using the battery.
Once the two, six cell battery packs are entire, you'll want to utilize the shrink wrap to safe them - and you will have your finish battery pack! Now you'll ability and fly your RC helicopter, aircraft, boat, automobile or truck without having complications!
