Making an RC Battery Pack - A Basic How-To
If you like RC, you realize the importance of a battery pack. The kind of batteries you decide on, how perfectly your pack is assembled And exactly how effectively you demand them are all critical areas to powering your RC car. Sure, you can buy a battery pack pre-assembled, but you can also Establish your individual and obtain the satisfaction of planning and powering your personal car.
The very first thing you might want to do is when you choose To place with each other a battery pack is what you're powering and the amount of juice you require. You furthermore may need to think about the subsequent:
one. Think about the chassis within your automobile. The kind of motor vehicle does not make any difference around the quantity of Room through which You should maneuver. The batteries may well should be oriented in a flat pack, a clustered pack or as each. It's also wise to think about the distribution of weight as part of your automobile - if the battery weight is going to be distributed in the side to facet or back to entrance fashion. In some cases your chassis Area for the battery pack isn't adaptable, so be aware of These constraints before you start.
two. Consider the motor powering your RC automobile. Depending on the electrical power needs, you'll establish the amount of batteries or cells you require. That is also if you can determine the type of batteries you'll use - if you want to keep your NiMH batteries or update to LiPo.
three. Identifying your voltage is really a very simple matter of addition. A standard cell voltage is one.2v, so wired in the sequence - twelve batteries will add as many as fourteen.4v - which would energy an 14.four volt RC electric motor.
Subsequent, You'll have to assemble your battery pack supplies - so Here is a sample shopping checklist. Keep in mind, we are assuming we are developing a battery pack with 14.4v, as in the example over:
o twelve Batteries or Battery Cells
o Automated Guided Vehicles (AGV) Battery 12 Battery Bars (you may purchase battery bars in bulk if you propose to construct more than one pack and help you save $)
o Wire: You will need an increased top quality 12 gage using a high strand rely. This kind of wire, Using these attributes will probably be additional adaptable which is right and being additional successful for electricity transmission.
o eighty-one hundred Watt Soldering Gun. You'll want a gun simply because you could be a lot more correct and more rapidly - this is critical because of the heat sensitivity of batteries. The more rapidly and a lot more unique you'll be able to be, the less likely You will be to wreck the battery.
o 60/forty Solder. This can be better quality - also critical for fast and exact perform and staying away from battery damage.
o Flux. It is a chemical cleansing agent that eliminates oxidation from metal to aid soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive is going to be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries appropriately and facilitate a tidy battery pack. The batteries end up essentially on the lookout like cord Wooden - tidily bundled.
o Soldering "Encouraging Palms" - optional. These products assist you to hold issues in place Whilst you solder.
o Another optional timesaver is to obtain a "Supporting Fingers" accessory for your personal soldering station.
o Multi Meter. You'll need a superior multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will allow you to take care of, strip and properly Reduce your twelve gage wire.
o The final ingredient is definitely the shrink wrap that may go around the whole assembly and hold it tidy. You can also have to have a heat gun to heat and shrink the wrap.
So, you have determined the best way to orient your batteries and the amount of you will need - now you will get to operate on assembly. For this example, we are assembling twelve battery cells - 6 down just one aspect and six down one other.
When you determine wherever the batteries are heading in relation in your chassis And just how they're going to get laid out, you are able to begin. For this example, as an instance we are accomplishing six down just one facet and 6 down the other aspect.
Just to be certain we are on exactly the same web page, the final word purpose Here's being running wire in the positive terminal of one's to start with battery towards the positive terminal on the electric RC motor and then working a wire with the detrimental terminal on the final battery in your pack to the optimistic terminal of your other battery pack, thus creating a finished circuit.
This necessarily mean you have to have adequate wire to achieve from your optimistic terminal of your 1st battery to that terminal and likewise from your damaging to accomplish the circuit with all your other battery pack so bear that in your mind.
Orientation. Align your 1st cell so that positive is pointing "upwards" and adverse is pointing "downwards" and afterwards reverse another battery so It really is reverse on down the line. If you purchased the battery assembly jig, This can be once you'd utilize it to align your cells and maintain them set up.
Adhere. Stick all the batteries along with your quickly drying adhesive to They are really if you want and aligned adequately.
Flux. Use your flux now over the link points.
Link - Use your battery bars to attach your cells. You'll have to warmth up your soldering gun and warmth up the battery bar. Using the bar shields the battery and when the flux starts to bubble, you employ your use of solder. The aim is to NOT heat the battery by itself. Heating the battery is not only counterproductive, because if you damage the battery it will not likely function, but also harmful because the cell may well explode if overheated.
You'll want to finish exactly the same methods for the remaining battery connections. You are connecting the adverse for the good repeatedly once again. You are going to then be All set to connect wiring for your battery pack.
The wires have to be pre-tinned which suggest you need to strip off 1 / 4 inch from the protective plastic wiring sheath, make use of the flux to clean them - implement the flux liberally - heat your solder gun and afterwards heat the wire and stream the solder in to the wire right until completely saturated. You may also want solder to the batteries Therefore the solder will act as the connector While using the battery.
As soon as the two, 6 mobile battery packs are complete, you will need to hire the shrink wrap to secure them - and you will have your comprehensive battery pack! Now you'll electricity and fly your RC helicopter, aircraft, boat, vehicle or truck without having challenges!
