Building an RC Battery Pack - A Standard How-To
If you like RC, you recognize the value of a battery pack. The type of batteries you select, how nicely your pack is assembled And the way competently you cost them are all crucial facets to powering your RC vehicle. Guaranteed, you can buy a battery pack pre-assembled, but you can also Construct your own personal and acquire the pleasure of designing and powering your personal vehicle.
The first thing you'll want to do is when you choose To place alongside one another a battery pack is what you are powering and the amount juice you require. You furthermore may require to consider the next:
1. Look at the chassis of one's motor vehicle. The kind of car does not subject as much as the amount of Place by which You should maneuver. The batteries could have to be oriented in a flat pack, a clustered pack or as each. You should also give thought to the distribution of weight inside your automobile - if the battery pounds will probably be dispersed within a facet to side or again to front manner. In some instances your chassis Room for your battery pack is not really adaptable, so be aware of Those people constraints before you start.
2. Think about the motor powering your RC motor vehicle. Depending upon the ability requirements, you'll be able to ascertain the number of batteries or cells you would like. That is also once you can come to a decision the kind of batteries you may use - if you want to keep the NiMH batteries or up grade to LiPo.
3. Pinpointing your voltage can be a very simple make a difference of addition. A regular cell voltage is one.2v, so wired in the collection - 12 batteries will insert around fourteen.4v - which would ability an fourteen.4 volt RC electric powered motor.
Up coming, You will need to assemble your battery pack provides - so This is a sample procuring list. Don't forget, we're assuming we are making a battery pack with fourteen.4v, as in the example higher than:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you can get battery bars in bulk if you plan to create more than one pack and preserve $)
o Wire: You'll want a better quality 12 gage by using a large strand depend. This type of wire, Using these features will probably be a lot more versatile which is ideal along with becoming a lot more economical for energy transmission.
o eighty-100 Watt Soldering Gun. You'll want a gun as you could be extra correct and a lot quicker - this is necessary due to the heat sensitivity of batteries. The more quickly plus more distinct you could be, the more unlikely You will be to break the battery.
o 60/40 Solder. That is bigger quality - also vital for brief and correct do the job and steering clear of battery destruction.
o Flux. This can be a chemical cleansing agent that eliminates oxidation from metal to facilitate soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying adhesive will be accustomed to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries adequately and facilitate a tidy battery pack. The batteries find yourself mainly wanting like twine wood - tidily bundled.
o Soldering "Serving to Palms" - optional. These products assist you to keep matters in position When you solder.
o Another optional timesaver is to secure a "Helping Hands" accent for your personal soldering station.
o Multi Meter. You'll need a very good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will assist you to handle, strip and appropriately Lower your 12 gage wire.
o The final component could be the shrink wrap which will go round the complete assembly and maintain it tidy. You will also need a heat gun to warmth and shrink the wrap.
So, you've discovered how to orient your batteries and the amount of you need - now you have to operate on assembly. For this instance, we're assembling twelve battery cells - six down a single facet and 6 down the other.
As soon as you establish exactly where the batteries are going in relation in your chassis And exactly how they are going to become laid out, you are able to start off. For this instance, as an example we are performing six down one particular facet and six down the other facet.
Just to be certain we're on exactly the same website page, the ultimate aim here is to become jogging wire through the beneficial terminal of your 1st battery for the favourable terminal on the electrical RC motor after which you can running a wire from the negative terminal on the final battery with your pack into the beneficial terminal of your other battery pack, therefore developing a finished circuit.
This suggest you might want to have sufficient wire to succeed in with the beneficial terminal of the first battery to that terminal and Also with the negative to complete the circuit with the other battery pack so bear that in mind.
Orientation. Align your 1st mobile so that favourable is pointing "upwards" and damaging is pointing "downwards" then reverse the next battery so It is reverse on down the road. If you bought the battery assembly jig, This is often when you'd use it to align your cells and maintain them in position.
Adhere. Stick every one of the batteries along with your rapid drying adhesive to They are really as a way and aligned effectively.
Flux. Make use of your flux now around the relationship details.
Relationship - Use your battery bars to connect your cells. You'll need to heat up your soldering gun and heat up the battery bar. Utilizing the bar guards the battery and when the flux begins to bubble, you employ your use of solder. The goal is to NOT heat the battery itself. Heating the battery is not just counterproductive, since for those who hurt the battery it will not operate, but also hazardous since the cell might explode if overheated.
You'll want to accomplish exactly the same steps for that remaining battery connections. You happen to be connecting the adverse towards the good time and again yet again. You may then be Prepared to connect wiring for your battery pack.
The wires must be pre-tinned which signify you have to strip off a quarter inch on the protecting plastic wiring sheath, utilize the flux to wash them - apply the Automated Guided Vehicles (AGV) Battery flux liberally - warmth your solder gun after which heat the wire and stream the solder to the wire right until carefully saturated. You may also want solder about the batteries Therefore the solder will act because the connector Using the battery.
As soon as the two, 6 mobile battery packs are full, you'll be wanting to make use of the shrink wrap to protected them - and you will have your finish battery pack! Now you can electrical power and fly your RC helicopter, plane, boat, motor vehicle or truck without having issues!
