Developing an RC Battery Pack - A Basic How-To
If you like RC, you know the significance of a battery pack. The kind of batteries you decide on, how effectively your pack is assembled And just how efficiently you charge them are all essential factors to powering your RC motor vehicle. Certain, You should buy a battery pack pre-assembled, but You can even Develop your individual and acquire the pleasure of developing and powering your individual automobile.
The very first thing you need to do is when you select to put with each other a battery pack is what you are powering and just how much juice you require. Additionally you will need to consider the following:
1. Think about the chassis of your respective motor vehicle. The kind of auto does not make any difference around the quantity of Room wherein You need to maneuver. The batteries could must be oriented in the flat pack, a clustered pack or as both equally. It's also wise to contemplate the distribution of body weight within your auto - if the battery bodyweight will likely be distributed inside a aspect to facet or back again to entrance fashion. Occasionally your chassis space for any battery pack will not be adaptable, so pay attention to those constraints before you start.
two. Look at the motor powering your RC car or truck. Depending on the power demands, you'll identify the quantity of batteries or cells you will need. That is also after you can choose the sort of batteries you can expect to use - if you would like keep your NiMH batteries or improve to LiPo.
3. Analyzing your voltage is mostly a uncomplicated subject of addition. A standard mobile voltage is one.2v, so wired in the series - 12 batteries will increase nearly 14.4v - which might electric power an 14.four volt RC electrical motor.
Upcoming, You will need to assemble your battery pack materials - so Here is a sample buying list. Bear in mind, we're assuming we are developing a battery pack with fourteen.4v, as in the example above:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to purchase battery bars in bulk if you propose to create multiple pack and conserve $)
o Wire: You'll be wanting the next excellent twelve gage which has a substantial strand rely. This kind of wire, Using these properties will likely be much more versatile which is right in addition to remaining much more productive for electrical power transmission.
o eighty-one hundred Watt Soldering Gun. You'll want a gun as you could be more specific and faster - this is important because of the heat sensitivity of batteries. The quicker and more unique it is possible to be, the less likely you'll be to damage the battery.
o sixty/40 Solder. That is better quality - also vital for brief and correct get the job done and averting battery problems.
o Flux. This can be a chemical cleaning agent that removes oxidation from steel to facilitate soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapid drying adhesive will probably 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 finish up basically looking like wire wood - tidily bundled.
o Soldering "Aiding Arms" - optional. These units allow you to keep issues in place As you solder.
o A further optional timesaver is to obtain a "Helping Arms" accent for the soldering station.
o Multi Meter. You will need a very good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These applications can help you cope with, strip and properly Slice your twelve gage wire.
o The ultimate ingredient would be the shrink wrap that will go around the complete assembly and retain it tidy. You can expect to also have to have a heat gun to heat and shrink the wrap.
So, you've discovered how you can orient your batteries and how many you will need - now you can get to work on assembly. For this example, we're assembling 12 battery cells - 6 down a single aspect and 6 down the other.
As soon as you discover exactly where the batteries are likely in relation towards your chassis and how they're going to generally be laid out, you may start. For this example, let's say we are undertaking 6 down one particular side and six down one other facet.
Just to verify we're on exactly the same webpage, the last word objective Here's being managing wire with the constructive terminal of your first battery into the beneficial terminal on the electric RC motor then functioning a wire in the negative terminal on the final battery in your pack on the favourable terminal of your other battery pack, thus making a accomplished circuit.
This mean you'll want to have ample wire to succeed in through the good terminal of one's initial battery to that terminal and Similarly within the adverse to finish the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your initial mobile to ensure good is pointing "upwards" and destructive is pointing "downwards" after which you can reverse another battery so It is really opposite on down the line. If you purchased the battery assembly jig, This is certainly whenever you'd utilize it to align your cells and keep them in position.
Adhere. Stick each of the batteries along with your quickly drying adhesive to They can be if you want and aligned adequately.
Flux. Make use of your flux now about the relationship details.
Link - Make use of 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 if the flux starts to bubble, you hire your usage of solder. The purpose is not to heat the battery alone. Heating the battery is not merely counterproductive, considering that for those who destruction the battery it will not perform, but will also risky because the mobile could explode if overheated.
You'll be wanting to finish the same ways for that remaining battery connections. You're connecting the unfavorable on the favourable again and again again. You are going to then be Completely ready to attach wiring for your battery pack.
The wires need to be pre-tinned which imply you should strip off 1 / 4 inch from the protecting plastic wiring sheath, make use of the flux to clean them - use the flux liberally - heat your solder gun then warmth the wire and circulation the solder into your wire until comprehensively saturated. You will also want solder over the batteries so the solder will act because the connector Using the battery.
After the two, six cell battery packs are finish, you'll be wanting to employ Automated Guided Vehicles (AGV) Battery the shrink wrap to secure them - and you'll have your full battery pack! Now you'll be able to ability and fly your RC helicopter, aircraft, boat, motor vehicle or truck without any troubles!
