Making an RC Battery Pack - A Basic How-To
If you love RC, you realize the necessity of a battery pack. The sort of batteries you end up picking, how properly your pack is assembled And just how efficiently you cost them are all essential features to powering your RC automobile. Absolutely sure, You should buy a battery pack pre-assembled, but You can even Construct your own and obtain the fulfillment of developing and powering your very own auto.
The first thing you need to do is when you select to put with each other a battery pack is what you're powering and exactly how much juice you may need. You furthermore may need to have to consider the next:
1. Think about the chassis of the car. The type of car or truck doesn't make a difference about the level of Room during which You need to maneuver. The batteries may should be oriented in a flat pack, a clustered pack or as equally. It's also wise to give thought to the distribution of excess weight with your car - whether or not the battery body weight is going to be distributed within a side to side or again to front manner. In some instances your chassis Area for a battery pack is just not adaptable, so be familiar with All those constraints before you start.
two. Consider the motor powering your RC car. Depending upon the electrical power needs, you can figure out how many batteries or cells you require. This is certainly also when you can make your mind up the kind of batteries you can use - if you need to keep your NiMH batteries or enhance to LiPo.
three. Figuring out your voltage can be a straightforward matter of addition. An ordinary cell voltage is one.2v, so wired within a collection - twelve batteries will add around 14.4v - which might electric power an 14.four volt RC electrical motor.
Up coming, You will need to collect your battery pack provides - so here's a sample buying checklist. Don't forget, we are assuming we're making a battery pack with fourteen.4v, as in the example higher than:
o twelve Batteries or Battery Cells
o 12 Battery Bars (it is possible to buy battery bars in bulk if you plan to construct more than one pack and help save $)
o Wire: You will need the next good quality 12 gage with a higher strand rely. This kind of wire, with these traits might be a lot more adaptable which is good in addition to staying much more efficient for electric power transmission.
o 80-one hundred Watt Soldering Gun. You'll want a gun as you can be a lot more precise and more rapidly - this is necessary because of the heat sensitivity of batteries. The faster and a lot more particular you may be, the not as likely you'll be to wreck the battery.
o sixty/40 Solder. This is often higher top quality - also essential for fast and accurate work and preventing battery harm.
o Flux. This is the 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 quick drying adhesive might be used to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries thoroughly and aid a tidy battery pack. The batteries wind up essentially looking like cord wood - tidily bundled.
o Soldering "Assisting Hands" - optional. These products help you keep items in place As you solder.
o An additional optional timesaver is to get a "Serving to Arms" accessory to your soldering station.
o Multi Meter. You need a very good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools will assist you to tackle, strip and thoroughly Lower your twelve gage wire.
o The ultimate element will be the shrink wrap which is able to go around the complete assembly and retain it tidy. You'll also need a warmth gun to warmth and shrink the wrap.
So, you've got determined the way to orient your Automated Guided Vehicles (AGV) Battery batteries and how many you need - now you get to work on assembly. For this instance, we're assembling 12 battery cells - 6 down 1 aspect and 6 down the opposite.
As you identify where the batteries are heading in relation for your chassis And the way they're going being laid out, it is possible to commence. For this instance, for example we are performing six down a person aspect and six down another aspect.
Just to be sure we're on the same page, the last word intention here is to generally be working wire within the positive terminal of your respective 1st battery on the constructive terminal on the electrical RC motor and then functioning a wire through the damaging terminal on the final battery in your pack into the beneficial terminal of the other battery pack, therefore creating a accomplished circuit.
This necessarily mean you need to have enough wire to achieve in the beneficial terminal of your to start with battery to that terminal and Furthermore from the detrimental to finish the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your initial mobile to ensure that favourable is pointing "upwards" and destructive is pointing "downwards" after which reverse the subsequent battery so It is really reverse on down the road. If you purchased the battery assembly jig, This is often if you'd use it to align your cells and hold them in position.
Adhere. Stick many of the batteries along with your rapidly drying adhesive to They are really so as and aligned correctly.
Flux. Make use of your flux now within 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 guards the battery and when the flux starts to bubble, you make use of your usage of solder. The intention is not to heat the battery itself. Heating the battery is not only counterproductive, because should you damage the battery it is not going to get the job done, but in addition unsafe as the mobile could explode if overheated.
You will need to accomplish the identical methods to the remaining battery connections. You are connecting the destructive to the positive repeatedly once again. You'll then be All set to attach wiring to the battery pack.
The wires need to be pre-tinned which mean you'll want to strip off a quarter inch with the protecting plastic wiring sheath, utilize the flux to clean them - apply the flux liberally - warmth your solder gun after which you can warmth the wire and stream the solder into the wire till extensively saturated. You will also want solder within the batteries Therefore the solder will act as the connector While using the battery.
When the two, 6 cell battery packs are finish, you will need to make use of the shrink wrap to protected them - and you'll have your finish battery pack! Now you'll be able to electric power and fly your RC helicopter, aircraft, boat, motor vehicle or truck without difficulties!
