Setting up an RC Battery Pack - A Standard How-To
If you love RC, you are aware of the significance of a battery pack. The sort of batteries you decide on, how nicely your pack is assembled and how effectively you demand them are all crucial facets to powering your RC car or truck. Sure, You should buy a battery pack pre-assembled, but you can also build your own and have the gratification of creating and powering your very own car or truck.
The very first thing you need to do is when you decide To place with each other a battery pack is what you are powering and exactly how much juice you require. You also want to consider the subsequent:
one. Look at the chassis within your auto. The kind of automobile does not matter just as much as the level of space wherein You need to maneuver. The batteries may well should be oriented within a flat pack, a clustered pack or as both equally. It's also advisable to consider the distribution of fat in the automobile - whether the battery excess weight will probably be dispersed inside of a side to aspect or back to front fashion. In some cases your chassis Area for just a battery pack will not be adaptable, so be aware of These constraints Before you begin.
2. Think about the motor powering your RC automobile. Depending on the power prerequisites, you'll be able to ascertain the amount of batteries or cells you need. That is also after you can come to a decision the type of batteries you can expect to use - if you need to keep your NiMH batteries or upgrade to LiPo.
three. Figuring out your voltage can be a basic matter of addition. An ordinary mobile voltage is one.2v, so wired inside a collection - twelve batteries will increase up to 14.4v - which might electricity an fourteen.four volt RC electrical motor.
Up coming, You'll have to collect your battery pack provides - so This is a sample purchasing record. Try to remember, we're assuming we're developing a battery pack with 14.4v, as in the instance earlier mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you can purchase battery bars in bulk if you propose to make multiple pack and preserve $)
o Wire: You'll be wanting an increased high quality twelve gage by using a high strand count. This kind of wire, with these traits will probably be a lot more adaptable which is ideal along with currently being far more efficient for energy transmission.
o eighty-one hundred Watt Soldering Gun. You'll want a gun since you could be much more precise and a lot quicker - this is essential as a result of heat sensitivity of batteries. The a lot quicker plus more precise you could be, the more unlikely You will be to damage the battery.
o 60/forty Solder. This is often increased excellent - also essential for rapid and accurate function and averting battery injury.
o Flux. This is a chemical cleaning agent that gets rid of oxidation from metallic to aid soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will likely be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries Automated Guided Vehicles (AGV) Battery correctly and aid a tidy battery pack. The batteries find yourself mainly searching like cord wood - tidily bundled.
o Soldering "Supporting Arms" - optional. These products help you hold items in place Whilst you solder.
o Yet another optional timesaver is to acquire a "Encouraging Arms" accessory for your soldering station.
o Multi Meter. You'll need a good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These tools can help you handle, strip and correctly cut your twelve gage wire.
o The ultimate element may be the shrink wrap which can go round the whole assembly and keep it tidy. You can also need a heat gun to warmth and shrink the wrap.
So, you've got discovered the way to orient your batteries and the number of you'll need - now you will get to operate on assembly. For this example, we're assembling 12 battery cells - six down a single aspect and six down the opposite.
As soon as you discover where by the batteries are likely in relation to your chassis and how they are going to generally be laid out, you may commence. For this instance, let's say we are doing 6 down a person facet and six down the opposite side.
Just to be certain we're on precisely the same web site, the final word purpose here is to generally be managing wire from your favourable terminal of your to start with battery to the beneficial terminal on the electrical RC motor after which you can running a wire within the adverse terminal on the last battery as part of your pack to your beneficial terminal of the other battery pack, therefore creating a completed circuit.
This mean you should have enough wire to achieve with the good terminal within your initial battery to that terminal and likewise within the negative to finish the circuit with your other battery pack so bear that in mind.
Orientation. Align your very first cell to ensure beneficial is pointing "upwards" and unfavorable is pointing "downwards" after which reverse the following battery so It can be reverse on down the road. If you bought the battery assembly jig, This is often after you'd utilize it to align your cells and maintain them set up.
Adhere. Stick each of the batteries together with your speedy drying adhesive to They are really so as and aligned adequately.
Flux. Use your flux now around the link points.
Link - Use your battery bars to attach your cells. You'll have to heat up your soldering gun and warmth up the battery bar. Utilizing the bar safeguards the battery and once the flux starts to bubble, you make use of your use of solder. The purpose is not to heat the battery by itself. Heating the battery is don't just counterproductive, considering that when you harm the battery it will never operate, but in addition unsafe since the cell might explode if overheated.
You'll be wanting to complete the exact same steps to the remaining battery connections. You happen to be connecting the unfavorable into the good repeatedly all over again. You may then be Prepared to connect wiring in your battery pack.
The wires need to be pre-tinned which suggest you'll want to strip off a quarter inch with the protective plastic wiring sheath, make use of the flux to scrub them - utilize the flux liberally - warmth your solder gun after which heat the wire and movement the solder into your wire until extensively saturated. You are going to also want solder around the batteries Hence the solder will act because the connector With all the battery.
When the two, six cell battery packs are comprehensive, you'll be wanting to make use of the shrink wrap to secure them - and you will have your entire battery pack! Now you'll electrical power and fly your RC helicopter, plane, boat, automobile or truck without complications!
