Developing an RC Battery Pack - A Simple How-To
If you like RC, you recognize the value of a battery pack. The type of batteries you choose, how perfectly your pack is assembled And the way proficiently you charge them are all significant factors to powering your RC car or truck. Confident, you can buy a battery pack pre-assembled, but You may as well Establish your individual and obtain the pleasure of developing and powering your own motor vehicle.
The very first thing you might want to do is when you select to put with each other a battery pack is what you are powering and how much juice you'll need. You furthermore may will need to Automated Guided Vehicles (AGV) Battery consider the next:
one. Consider the chassis of your auto. The kind of car or truck isn't going to make any difference up to the amount of Place wherein You should maneuver. The batteries may must be oriented inside a flat pack, a clustered pack or as both. You should also contemplate the distribution of body weight within your auto - whether or not the battery fat will probably be dispersed in the side to aspect or again to entrance fashion. Occasionally your chassis space for any battery pack isn't adaptable, so be familiar with All those constraints Before you begin.
two. Look at the motor powering your RC car. Depending on the electricity specifications, you'll establish how many batteries or cells you may need. This is certainly also whenever you can come to a decision the sort of batteries you'll use - if you want to keep the NiMH batteries or enhance to LiPo.
3. Identifying your voltage can be a easy make a difference of addition. A regular mobile voltage is 1.2v, so wired inside of a series - twelve batteries will insert around 14.4v - which would electrical power an fourteen.four volt RC electric motor.
Future, you'll need to collect your battery pack materials - so here's a sample purchasing checklist. Don't forget, we're assuming we're developing a battery pack with fourteen.4v, as in the example earlier mentioned:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to purchase battery bars in bulk if you intend to develop multiple pack and conserve $)
o Wire: You'll want a greater excellent twelve gage using a higher strand rely. This type of wire, with these characteristics will likely be extra adaptable which is right as well as currently being a lot more economical for ability transmission.
o eighty-100 Watt Soldering Gun. You'll want a gun because you may be far more exact and quicker - this is necessary due to heat sensitivity of batteries. The more quickly and more distinct it is possible to be, the not as likely you'll be to damage the battery.
o 60/forty Solder. This really is greater top quality - also significant for brief and correct function and averting battery hurt.
o Flux. This can be a chemical cleansing agent that gets rid of oxidation from metallic to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will be used to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries correctly and facilitate a tidy battery pack. The batteries wind up essentially searching like twine wood - tidily bundled.
o Soldering "Aiding Fingers" - optional. These devices allow you to maintain issues set up As you solder.
o A different optional timesaver is to secure a "Aiding Hands" accent for the soldering station.
o Multi Meter. You need a very good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These tools can help you cope with, strip and effectively Slice your twelve gage wire.
o The ultimate ingredient would be the shrink wrap that can go round the entire assembly and continue to keep it tidy. You will also require a heat gun to warmth and shrink the wrap.
So, you've got determined the way to orient your batteries and the number of you need - now you have to operate on assembly. For this instance, we're assembling 12 battery cells - six down one aspect and 6 down the other.
As soon as you discover where the batteries are going in relation towards your chassis and how they're going being laid out, you'll be able to start. For this instance, as an instance we're executing six down just one facet and six down the other aspect.
Just to be certain we're on the identical web site, the last word intention here is being working wire within the beneficial terminal of your very first battery on the optimistic terminal on the electric RC motor and then managing a wire in the destructive terminal on the last battery as part of your pack towards the positive terminal of your other battery pack, thus making a completed circuit.
This imply you should have sufficient wire to reach from your beneficial terminal of one's 1st battery to that terminal and Similarly from the damaging to accomplish the circuit using your other battery pack so bear that in your mind.
Orientation. Align your initial mobile in order that beneficial is pointing "upwards" and negative is pointing "downwards" and afterwards reverse the next battery so It truly is reverse on down the line. If you bought the battery assembly jig, This really is when you'd use it to align your cells and keep them in place.
Adhere. Adhere every one of the batteries along with your quick drying adhesive to They may be if you want and aligned adequately.
Flux. Make use of your flux now to the relationship factors.
Relationship - Make use of your battery bars to connect your cells. You'll need to heat up your soldering gun and heat up the battery bar. Using the bar safeguards the battery and if the flux begins to bubble, you use your usage of solder. The target is not to warmth the battery alone. Heating the battery is not simply counterproductive, given that in the event you problems the battery it will not get the job done, but also harmful as the cell may well explode if overheated.
You'll be wanting to complete the exact same methods for the remaining battery connections. You might be connecting the unfavorable towards the constructive time and again again. You are going to then be Completely ready to attach wiring to the battery pack.
The wires need to be pre-tinned which suggest you should strip off 1 / 4 inch with the protective plastic wiring sheath, utilize the flux to clean them - utilize the flux liberally - heat your solder gun after which warmth the wire and flow the solder in to the wire right until carefully saturated. You are going to also want solder over the batteries And so the solder will act given that the connector with the battery.
As soon as the two, six cell battery packs are full, you'll be wanting to make use of the shrink wrap to secure them - and you'll have your finish battery pack! Now you'll energy and fly your RC helicopter, plane, boat, auto or truck without troubles!
