Building an RC Battery Pack - A Basic How-To
If you like RC, you understand the significance of a battery pack. The type of batteries you end up picking, how properly your pack is assembled and how successfully you demand them are all vital facets to powering your RC vehicle. Sure, you can buy a battery pack pre-assembled, but You may also Create your own personal and obtain the pleasure of coming up with and powering your individual motor vehicle.
The first thing you'll want to do is when you decide To place with each other a battery pack is what you're powering and the amount of juice you may need. You also require to think about the next:
one. Consider the chassis of one's car or truck. The kind of vehicle does not make any difference approximately the amount of Place wherein You will need to maneuver. The batteries could have to be oriented in a flat pack, a clustered pack or as both equally. It's also wise to take into consideration the distribution of bodyweight inside your auto - whether the battery fat will likely be distributed inside a aspect to side or back to entrance method. Occasionally your chassis Room for a battery pack is just not adaptable, so pay attention to People constraints Before you begin.
two. Consider the motor powering your RC auto. Depending on the power requirements, you'll be able to determine the quantity of batteries or cells you will need. That is also any time you can determine the sort of batteries you can expect to use - if you wish to keep your NiMH batteries or improve to LiPo.
three. Analyzing your voltage is really a uncomplicated make any difference of addition. An ordinary cell voltage is 1.2v, so wired within a series - 12 batteries will include approximately fourteen.4v - which would energy an fourteen.four volt RC electrical motor.
Future, you'll need to collect your battery pack materials - so here's a sample buying record. Don't forget, we're assuming we are making a battery pack with fourteen.4v, as in the example above:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you may buy battery bars in bulk if you propose to develop more than one pack and help you save $)
o Wire: You will need an increased high quality twelve gage by using a significant strand depend. This sort of wire, Using these properties will be extra flexible which is ideal in addition to being more productive for electric power transmission.
o 80-a hundred Watt Soldering Gun. You'll be wanting a gun as you can be extra precise and faster - this is essential due to the warmth sensitivity of batteries. The faster and more particular you could be, the less likely You will be to break the battery.
o 60/forty Solder. This is increased high-quality - also significant for rapid and exact perform and preventing battery damage.
o Flux. It is a chemical cleansing agent that eliminates oxidation from metal 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 likely be utilized to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries effectively and facilitate a tidy battery pack. The batteries end up basically seeking like wire wood - tidily bundled.
o Soldering "Supporting Hands" Automated Guided Vehicles (AGV) Battery - optional. These devices let you keep matters set up When you solder.
o A different optional timesaver is to secure a "Encouraging Palms" accessory to your soldering station.
o Multi Meter. You need a great multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications will help you cope with, strip and properly Lower your twelve gage wire.
o The ultimate component will be the shrink wrap which is able to go around the overall assembly and hold it tidy. You can expect to also require a warmth gun to warmth and shrink the wrap.
So, you've got discovered how to orient your batteries and how many you require - now you have to work on assembly. For this example, we're assembling 12 battery cells - six down one facet and six down the other.
When you establish exactly where the batteries are going in relation to your chassis And exactly how they are going to become laid out, you are able to commence. For this example, let's say we are accomplishing 6 down a person aspect and six down the opposite facet.
Just to be sure we're on exactly the same page, the last word aim Here's for being managing wire in the favourable terminal of the initial battery to the optimistic terminal on the electrical RC motor and afterwards running a wire from your detrimental terminal on the final battery within your pack to your beneficial terminal of one's other battery pack, therefore making a finished circuit.
This necessarily mean you should have ample wire to reach in the favourable terminal of the to start with battery to that terminal and Also from the destructive to finish the circuit with your other battery pack so bear that in your mind.
Orientation. Align your initially mobile in order that favourable is pointing "upwards" and detrimental is pointing "downwards" then reverse the subsequent battery so It really is opposite on down the line. If you bought the battery assembly jig, This is certainly when you'd use it to align your cells and maintain them in position.
Adhere. Adhere many of the batteries along with your rapidly drying adhesive to They may be in order and aligned correctly.
Flux. Make use of your flux now around the connection factors.
Link - Use your battery bars to attach your cells. You'll need to warmth up your soldering gun and warmth up the battery bar. Utilizing the bar shields the battery and in the event the flux starts to bubble, you utilize your usage of solder. The intention is not to warmth the battery itself. Heating the battery is not merely counterproductive, due to the fact should you destruction the battery it will not likely operate, but also hazardous as the mobile may possibly explode if overheated.
You'll be wanting to finish precisely the same techniques for that remaining battery connections. You happen to be connecting the negative to the good time and again once more. You can then be ready to connect wiring in your battery pack.
The wires have to be pre-tinned which mean you have to strip off a quarter inch of your protecting plastic wiring sheath, utilize the flux to clean them - utilize the flux liberally - warmth your solder gun and afterwards heat the wire and flow the solder into your wire until thoroughly saturated. You will also want solder on the batteries so the solder will act since the connector with the battery.
After the two, 6 mobile battery packs are total, you will need to make use of the shrink wrap to safe them - and you'll have your total battery pack! Now you'll energy and fly your RC helicopter, aircraft, boat, car or truck with no problems!
