Creating an RC Battery Pack - A Simple How-To
If you like RC, you recognize the value of a battery pack. The sort of batteries you decide on, how very well your pack is assembled And the way effectively you demand them are all crucial elements to powering your RC car or truck. Guaranteed, you can buy a battery pack pre-assembled, but You can even Make your personal and acquire the satisfaction of building and powering your own motor vehicle.
The very first thing you'll want to do is when you decide To place collectively a battery pack is what you're powering and how much juice you will need. In addition, you will need to think about the subsequent:
1. Think about the chassis of your car or truck. The type of car won't make any difference around the quantity of Area where You should maneuver. The batteries might have to be oriented within a flat pack, a clustered pack or as both of those. It's also wise to think of the distribution of bodyweight within your auto - whether or not the battery pounds will probably be distributed inside a facet to side or back to entrance way. In some instances your chassis space for just a battery pack is just not adaptable, so know about People constraints before you start.
two. Look at the motor powering your RC vehicle. According to the electrical power needs, you can ascertain the number of batteries or cells you'll need. That is also if you can make a decision the type of batteries you'll use - in order to maintain your NiMH batteries or upgrade to LiPo.
3. Determining your voltage can be a simple make any difference of addition. A normal mobile voltage is 1.2v, so wired in a very series - twelve batteries will include nearly fourteen.4v - which would electric power an fourteen.4 volt RC electric motor.
Following, You will need to collect your battery pack supplies - so Here is a sample procuring listing. Don't forget, we are assuming we're making a battery pack with 14.4v, as in the instance previously mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you'll be able to get battery bars in bulk if you propose to construct more than one pack and preserve $)
o Wire: You will need an increased quality twelve gage which has a large strand depend. This type of wire, Using these attributes are going to be more adaptable which is right and also being extra efficient for electrical power transmission.
o 80-100 Watt Soldering Gun. You'll want a gun since you is usually more specific and faster - this is necessary due to warmth sensitivity of batteries. The a lot quicker plus much more specific you can be, the more unlikely You will be to wreck the battery.
o 60/forty Solder. This is better good quality - also crucial for brief and correct operate and averting battery problems.
o Flux. This is a chemical cleaning agent that gets rid of oxidation from metallic to aid soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive might be accustomed to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries correctly and aid a tidy battery pack. The batteries turn out essentially on the lookout like twine wood - tidily bundled.
o Soldering Automated Guided Vehicles (AGV) Battery "Helping Arms" - optional. These gadgets help you hold factors in place Whilst you solder.
o One more optional timesaver is to acquire a "Serving to Fingers" accent to your soldering station.
o Multi Meter. You will need a very good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These instruments can help you handle, strip and adequately Slash your twelve gage wire.
o The ultimate element is definitely the shrink wrap that can go round the whole assembly and continue to keep it tidy. You are going to also require a heat gun to heat and shrink the wrap.
So, you have discovered the way to orient your batteries and the number of you'll need - now you receive to operate on assembly. For this instance, we are assembling twelve battery cells - 6 down one aspect and 6 down another.
After you discover the place the batteries are likely in relation to the chassis And just how they are going to be laid out, it is possible to commence. For this example, let's say we're doing six down 1 side and 6 down the opposite facet.
Just to verify we are on the exact same web page, the final word objective here is to become functioning wire through the good terminal of one's first battery for the beneficial terminal on the electric RC motor and afterwards functioning a wire through the damaging terminal on the last battery in the pack into the favourable terminal of your other battery pack, thereby making a concluded circuit.
This mean you must have ample wire to succeed in within the constructive terminal of one's very first battery to that terminal and Also in the detrimental to complete the circuit along with your other battery pack so bear that in your mind.
Orientation. Align your first cell so that beneficial is pointing "upwards" and destructive is pointing "downwards" after which you can reverse the following battery so it's opposite on down the line. If you purchased the battery assembly jig, this is if you'd use it to align your cells and hold them set up.
Adhere. Stick the many batteries along with your quickly drying adhesive to They're so as and aligned appropriately.
Flux. Use your flux now within the link points.
Link - Make use of your battery bars to attach your cells. You'll need to heat up your soldering gun and heat up the battery bar. Using the bar guards the battery and in the event the flux begins to bubble, you use your use of solder. The aim is to NOT heat the battery itself. Heating the battery is not merely counterproductive, given that when you destruction the battery it will not perform, but will also dangerous because the cell might explode if overheated.
You will need to accomplish the identical techniques for your remaining battery connections. You're connecting the destructive into the optimistic repeatedly once more. You'll then be ready to connect wiring for your battery pack.
The wires need to be pre-tinned which necessarily mean you might want to strip off a quarter inch in the protective plastic wiring sheath, use the flux to clean them - apply the flux liberally - warmth your solder gun then warmth the wire and move the solder into the wire until eventually totally saturated. You can expect to also want solder on the batteries And so the solder will act as being the connector with the battery.
After the two, six cell battery packs are complete, you'll be wanting to utilize the shrink wrap to safe them - and you'll have your total battery pack! Now you can electric power and fly your RC helicopter, airplane, boat, motor vehicle or truck without any complications!
