Developing an RC Battery Pack - A Basic How-To
If you're keen on RC, you know the value of a battery pack. The kind of batteries you select, how effectively your pack is assembled And exactly how efficiently you charge them are all critical elements to powering your RC automobile. Sure, you can buy a battery pack pre-assembled, but Automated Guided Vehicles (AGV) Battery You may as well Develop your personal and get the gratification of planning and powering your own private car or truck.
The first thing you'll want to do is when you decide to put with each other a battery pack is what you are powering and simply how much juice you will need. You furthermore may will need to think about the following:
1. Look at the chassis of the motor vehicle. The kind of automobile isn't going to make a difference as much as the level of Place by which You must maneuver. The batteries might have to be oriented inside of a flat pack, a clustered pack or as each. You should also take into consideration the distribution of fat inside your vehicle - whether or not the battery body weight will be distributed in a facet to facet or back again to entrance method. In some cases your chassis Place to get a battery pack is just not adaptable, so be familiar with People constraints Before you begin.
two. Look at the motor powering your RC car or truck. Dependant upon the energy requirements, you'll ascertain the quantity of batteries or cells you require. That is also whenever you can make a decision the kind of batteries you may use - if you want to keep the NiMH batteries or update to LiPo.
three. Figuring out your voltage is really a easy subject of addition. A regular cell voltage is 1.2v, so wired inside a collection - twelve batteries will add as many as 14.4v - which might energy an fourteen.4 volt RC electrical motor.
Up coming, You will need to assemble your battery pack provides - so Here is a sample shopping list. Keep in mind, we're assuming we're developing a battery pack with fourteen.4v, as in the instance over:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to get battery bars in bulk if you intend to create more than one pack and conserve $)
o Wire: You'll want the next high-quality 12 gage which has a superior strand rely. This sort of wire, with these features will probably be far more versatile which is right and remaining additional efficient for electric power transmission.
o 80-100 Watt Soldering Gun. You'll want a gun because you could be extra specific and a lot quicker - this is important due to the warmth sensitivity of batteries. The more quickly plus more certain you are able to be, the more unlikely You will be to break the battery.
o 60/40 Solder. This is better excellent - also vital for fast and correct work and preventing battery harm.
o Flux. This can be a chemical cleaning agent that gets rid of oxidation from metal to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive are going to be utilized to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries properly and facilitate a tidy battery pack. The batteries turn out fundamentally wanting like twine wood - tidily bundled.
o Soldering "Assisting Hands" - optional. These gadgets permit you to maintain points set up When you solder.
o One more optional timesaver is to get a "Assisting Hands" accessory in your soldering station.
o Multi Meter. You will need a great multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will assist you to handle, strip and correctly Minimize your 12 gage wire.
o The ultimate component is definitely the shrink wrap that may go around the overall assembly and keep it tidy. You are going to also need a warmth gun to heat and shrink the wrap.
So, you've got determined ways to orient your batteries and how many you would like - now you receive to work on assembly. For this example, we're assembling 12 battery cells - six down just one aspect and six down the other.
Once you determine the place the batteries are going in relation for your chassis And exactly how they're going to become laid out, you may start. For this instance, as an example we are accomplishing 6 down just one side and 6 down one other facet.
Just to make certain we're on exactly the same web site, the ultimate purpose here is for being functioning wire within the good terminal of one's first battery to the beneficial terminal on the electrical RC motor after which you can functioning a wire through the unfavorable terminal on the last battery within your pack to the favourable terminal of one's other battery pack, thereby developing a finished circuit.
This signify you have to have enough wire to achieve with the beneficial terminal within your initially battery to that terminal and likewise through the destructive to finish the circuit with the other battery pack so bear that in mind.
Orientation. Align your initial mobile to make sure that optimistic is pointing "upwards" and destructive is pointing "downwards" then reverse the next battery so It can be reverse on down the line. If you bought the battery assembly jig, That is if you'd utilize it to align your cells and hold them in position.
Adhere. Adhere all the batteries along with your speedy drying adhesive to They can be as a way and aligned correctly.
Flux. Make use of your flux now about the connection points.
Connection - Make use of your battery bars to connect your cells. You'll have to warmth up your soldering gun and heat up the battery bar. Using the bar protects the battery and when the flux begins to bubble, you hire your utilization of solder. The goal is to NOT heat the battery by itself. Heating the battery is not just counterproductive, since if you harm the battery it would not perform, and also perilous as the mobile could possibly explode if overheated.
You'll be wanting to finish precisely the same actions for that remaining battery connections. You happen to be connecting the damaging into the positive time and again once more. You may then be ready to connect wiring towards your battery pack.
The wires need to be pre-tinned which suggest you'll want to strip off 1 / 4 inch with the protecting plastic wiring sheath, make use of the flux to clean them - apply the flux liberally - warmth your solder gun then heat the wire and movement the solder in the wire right until completely saturated. You'll also want solder around the batteries Hence the solder will act since the connector Together with the battery.
When the two, 6 cell battery packs are finish, you will need to use the shrink wrap to protected them - and you will have your entire battery pack! Now you can ability and fly your RC helicopter, airplane, boat, motor vehicle or truck without any difficulties!
