Making an RC Battery Pack - A Basic How-To
If you love RC, you are aware of the value of a battery pack. The type of batteries you decide on, how effectively your pack is assembled And the way competently you cost them are all crucial facets to powering your RC auto. Positive, You should buy a battery pack pre-assembled, but You may also Establish your individual and get the satisfaction of creating and powering your own private car.
The first thing you might want to do is when you decide to put alongside one another a battery pack is what you are powering and simply how much juice you need. You also need to have to consider the next:
one. Think about the chassis of your respective car or truck. The sort of automobile isn't going to subject about the level of Place in which You should maneuver. The batteries might should be oriented in a very flat pack, a clustered pack or as equally. It's also wise to contemplate the distribution of bodyweight in your car or truck - if the battery body weight will likely be distributed in the facet to aspect or back to front fashion. In some instances your chassis House for the battery pack is just not adaptable, so be aware of Those people constraints before you start.
two. Think about the motor powering your RC automobile. According to the electricity specifications, you'll establish the amount of batteries or cells you may need. This is certainly also if you can decide the sort of batteries you'll use - in order to keep the NiMH batteries or upgrade to LiPo.
3. Analyzing your voltage is mostly a very simple make a difference of addition. A standard mobile voltage is 1.2v, so wired inside of a collection - 12 batteries will insert up to fourteen.4v - which might electric power an 14.four volt RC electric powered motor.
Up coming, You'll have to collect your battery pack materials - so Here is a sample shopping checklist. Recall, we are assuming we're developing a battery pack with 14.4v, as in the example earlier mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you are able to purchase battery bars in bulk if you propose to create more than one pack and help you save $)
o Wire: You'll want a greater high quality 12 gage which has a large strand count. This type of wire, with these features will likely be additional versatile which is ideal along with staying much more economical for ability transmission.
o 80-a hundred Watt Soldering Gun. You'll want a gun as you could be additional correct and a lot quicker - this is critical due to the heat sensitivity of batteries. The quicker and more distinct it is possible to be, the more unlikely you'll be to wreck the battery.
o 60/40 Solder. This is often increased good quality - also significant for fast and exact operate and avoiding battery hurt.
o Flux. That is a chemical cleansing agent that removes oxidation from metallic to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive will be accustomed to bundle the batteries alongside one another.
o Automated Guided Vehicles (AGV) Battery Battery Pack Assembly Jig - optional. These assembly products align the batteries thoroughly and aid a tidy battery pack. The batteries turn out in essence looking like twine wood - tidily bundled.
o Soldering "Helping Arms" - optional. These units permit you to hold things in position while you solder.
o A further optional timesaver is to obtain a "Aiding Palms" accessory for your soldering station.
o Multi Meter. You will need a superior multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These applications will help you manage, strip and appropriately Slash your twelve gage wire.
o The final ingredient could be the shrink wrap that can go across the full assembly and continue to keep it tidy. You can expect to also have to have a warmth gun to warmth and shrink the wrap.
So, you have identified how to orient your batteries and the number of you will need - now you receive to work on assembly. For this instance, we are assembling twelve battery cells - six down just one aspect and 6 down the other.
As you establish where by the batteries are going in relation to your chassis And exactly how they are going to become laid out, you could get started. For this example, for example we're doing six down 1 facet and six down one other aspect.
Just to be sure we are on precisely the same webpage, the final word goal Here's to be running wire with the positive terminal of your first battery to the positive terminal on the electric RC motor and then managing a wire with the detrimental terminal on the last battery in the pack towards the beneficial terminal of your other battery pack, thus developing a accomplished circuit.
This necessarily mean you have to have sufficient wire to succeed in with the favourable terminal of the first battery to that terminal and likewise through the unfavorable to complete the circuit with all your other battery pack so bear that in mind.
Orientation. Align your first cell to ensure good is pointing "upwards" and damaging is pointing "downwards" after which reverse another battery so It can be opposite on down the line. If you purchased the battery assembly jig, This really is whenever you'd utilize it to align your cells and maintain them set up.
Adhere. Stick all the batteries together with your quickly drying adhesive to they are if you want and aligned appropriately.
Flux. Use your flux now within the connection factors.
Relationship - Make use of your battery bars to attach your cells. You will need to warmth up your soldering gun and warmth up the battery bar. Using the bar guards the battery and in the event the flux starts to bubble, you hire your utilization of solder. The purpose is not to heat the battery alone. Heating the battery is not only counterproductive, considering that should you hurt the battery it would not perform, but in addition harmful because the mobile may well explode if overheated.
You'll want to complete precisely the same actions for that remaining battery connections. You're connecting the detrimental to the favourable time and again yet again. You may then be Prepared to connect wiring on your battery pack.
The wires must be pre-tinned which suggest you should strip off 1 / 4 inch on the protecting plastic wiring sheath, use the flux to scrub them - use the flux liberally - warmth your solder gun after which you can warmth the wire and stream the solder to the wire until finally completely saturated. You'll also want solder about the batteries Therefore the solder will act as the connector Along with the battery.
After the two, 6 cell battery packs are complete, you will need to utilize the shrink wrap to secure them - and you'll have your full battery pack! Now you'll power and fly your RC helicopter, aircraft, boat, motor vehicle or truck without complications!
