Building an RC Battery Pack - A Standard How-To
If you like RC, you recognize the value of a battery pack. The sort of batteries you choose, how well your pack is assembled And just how efficiently you cost them are all important features to powering your RC automobile. Sure, You should purchase a battery pack pre-assembled, but It's also possible to Establish your very own and have the gratification of developing and powering your own private automobile.
The very first thing you must do is when you choose To place collectively a battery pack is what you're powering and how much juice you may need. You furthermore mght will need to consider the next:
1. Consider the chassis of one's auto. The sort of car or truck would not make any difference up to the quantity of space by which You should maneuver. The batteries might need to be oriented inside of a flat pack, a clustered pack or as the two. It's also advisable to take into consideration the distribution of fat as part of your vehicle - whether or not the battery pounds will be distributed in the facet to facet or back to front manner. In some instances your chassis Place to get a battery pack is not adaptable, so know about All those constraints before you start.
2. Consider the motor powering your RC vehicle. Depending upon the electrical power demands, you'll be able to determine the number of batteries or cells you may need. This really is also when you can determine the kind of batteries you will use - if you need to maintain your NiMH batteries or enhance to LiPo.
3. Identifying your voltage is mostly a simple make any difference of addition. An ordinary cell voltage is 1.2v, so wired in a collection - 12 batteries will increase up to 14.4v - which might electrical power an 14.4 volt RC electric powered motor.
Next, You will need to gather your battery pack supplies - so This is a sample buying checklist. Recall, we are assuming we're making a battery pack with 14.4v, as in the instance higher than:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to purchase battery bars in bulk if you plan to develop more than one pack and preserve $)
o Wire: You'll want a better top quality twelve gage using a substantial strand depend. This sort of wire, Using these traits will probably be more flexible which is good as well as becoming additional economical for electrical power transmission.
o 80-one hundred Watt Soldering Gun. You will need a gun since you is often more correct and more rapidly - this is essential due to the warmth sensitivity of batteries. The quicker and even more distinct it is possible to be, the less likely You will be to wreck the battery.
o 60/forty Solder. This is often bigger top quality - also essential for rapid and exact do the job and averting battery problems.
o Flux. This can be a chemical cleaning agent that eliminates oxidation from metal to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Automated Guided Vehicles (AGV) Battery Shoo Goo or Goop. This fast drying adhesive will likely be used to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries effectively and aid a tidy battery pack. The batteries finish up essentially on the lookout like wire Wooden - tidily bundled.
o Soldering "Aiding Palms" - optional. These gadgets permit you to maintain points set up When you solder.
o An additional optional timesaver is to get a "Supporting Arms" accent for the soldering station.
o Multi Meter. You need a good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These resources will allow you to tackle, strip and correctly Slash your twelve gage wire.
o The ultimate part will be the shrink wrap that will go throughout the whole assembly and keep it tidy. You'll also require a heat gun to heat and shrink the wrap.
So, you have identified the way to orient your batteries and how many you may need - now you can get to work on assembly. For this instance, we're assembling twelve battery cells - six down one aspect and six down the other.
As soon as you determine where the batteries are heading in relation towards your chassis And the way they're going to be laid out, you'll be able to get started. For this example, for example we are performing 6 down a person side and six down the opposite facet.
Just to ensure we are on precisely the same site, the last word target Here's for being jogging wire from the optimistic terminal of your respective initially battery towards the constructive terminal on the electrical RC motor and then functioning a wire from your detrimental terminal on the last battery in your pack towards the optimistic terminal of one's other battery pack, therefore developing a finished circuit.
This mean you might want to have enough wire to achieve within the favourable terminal within your first battery to that terminal and Also from your destructive to complete the circuit with the other battery pack so bear that in mind.
Orientation. Align your initial cell so that constructive is pointing "upwards" and detrimental is pointing "downwards" and after that reverse the subsequent battery so It really is reverse on down the line. If you purchased the battery assembly jig, This is often if you'd use it to align your cells and maintain them in place.
Adhere. Stick all of the batteries along with your quick drying adhesive to They're as a way and aligned appropriately.
Flux. Make use of your flux now to the relationship factors.
Link - Use your battery bars to attach your cells. You'll have to heat up your soldering gun and heat up the battery bar. Utilizing the bar shields the battery and when the flux starts to bubble, you make use of your utilization of solder. The purpose is not to warmth the battery itself. Heating the battery is not just counterproductive, given that if you harm the battery it would not operate, but additionally dangerous as the cell may possibly explode if overheated.
You will need to finish precisely the same actions with the remaining battery connections. That you are connecting the destructive to the positive again and again once again. You can expect to then be Completely ready to attach wiring to the battery pack.
The wires have to be pre-tinned which necessarily mean you'll want to strip off 1 / 4 inch in the protecting plastic wiring sheath, make use of the flux to scrub them - use the flux liberally - heat your solder gun then warmth the wire and stream the solder into your wire until totally saturated. You'll also want solder over the batteries Therefore the solder will act as the connector with the battery.
After the two, six mobile battery packs are comprehensive, you'll be wanting to utilize the shrink wrap to safe them - and you will have your finish battery pack! Now you can energy and fly your RC helicopter, aircraft, boat, car or truck without any issues!
