Creating an RC Battery Pack - A Primary How-To
If you're keen on RC, you are aware of the value of a battery pack. The type of batteries you decide on, how perfectly your pack is assembled and how successfully you demand them are all important elements to powering your RC motor vehicle. Guaranteed, You should purchase a battery pack pre-assembled, but It's also possible to build your own private and obtain the pleasure of planning and powering your individual automobile.
The very first thing you might want to do is when you decide to put with each other a battery pack is what you are powering and exactly how much juice you may need. You furthermore may require to consider the subsequent:
one. Look at the chassis of your respective automobile. The sort of motor vehicle will not subject just as much as the level of Room during which You need to maneuver. The batteries may perhaps should be oriented in a very flat pack, a clustered pack or as both equally. You should also contemplate the distribution of body weight in the car - whether the battery fat will likely be distributed in the side to facet or back to front manner. Occasionally your chassis space for just a battery pack is just not adaptable, so concentrate on Individuals constraints Before you begin.
2. Look at the motor powering your RC vehicle. Dependant upon the ability needs, you'll identify the number of batteries or cells you'll need. This is also after you can come to a decision the kind of batteries you can expect to use - if you would like maintain your NiMH batteries or enhance to LiPo.
3. Identifying your voltage is known as a very simple issue of addition. An ordinary cell voltage is one.2v, so wired within a sequence - 12 batteries will add as much as 14.4v - which would electricity an fourteen.four volt RC electric powered motor.
Up coming, you'll need to gather your battery pack supplies - so Here is a sample buying record. Don't forget, we're assuming we're making a battery pack with fourteen.4v, as in the example previously mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you can order battery bars in bulk if you plan to Automated Guided Vehicles (AGV) Battery create more than one pack and conserve $)
o Wire: You'll want the next high quality twelve gage having a high strand depend. This sort of wire, with these features will probably be extra flexible which is good as well as getting much more successful for electric power transmission.
o 80-a hundred Watt Soldering Gun. You'll be wanting a gun as you might be more specific and a lot quicker - this is critical because of the heat sensitivity of batteries. The more quickly and more unique you can be, the less likely you'll be to wreck the battery.
o sixty/forty Solder. This is certainly bigger excellent - also essential for brief and precise function and steering clear of battery damage.
o Flux. This is a chemical cleansing agent that gets rid of oxidation from steel to aid soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive might be used to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries adequately and aid a tidy battery pack. The batteries find yourself generally wanting like twine wood - tidily bundled.
o Soldering "Helping Hands" - optional. These units help you maintain items in position As you solder.
o An additional optional timesaver is to get a "Assisting Arms" accent for your personal soldering station.
o Multi Meter. You need a excellent multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will assist you to tackle, strip and correctly cut your twelve gage wire.
o The final component is the shrink wrap which will go across the whole assembly and hold it tidy. You will also require a warmth gun to warmth and shrink the wrap.
So, you've recognized the way to orient your batteries and the amount of you would like - now you will get to operate on assembly. For this instance, we are assembling 12 battery cells - 6 down one facet and six down another.
Once you determine where by the batteries are going in relation in your chassis And exactly how they are going for being laid out, you are able to commence. For this instance, for example we're undertaking six down a person facet and 6 down another facet.
Just to verify we are on the exact same website page, the ultimate intention here is to get operating wire within the good terminal of one's very first battery into the good terminal on the electric RC motor and after that working a wire from the detrimental terminal on the last battery in the pack for the favourable terminal of one's other battery pack, thereby making a finished circuit.
This signify you have to have enough wire to achieve through the favourable terminal of the initial battery to that terminal and Also from your destructive to finish the circuit along with your other battery pack so bear that in your mind.
Orientation. Align your first cell to ensure that optimistic is pointing "upwards" and destructive is pointing "downwards" then reverse the following battery so It really is reverse on down the line. If you purchased the battery assembly jig, This can be if you'd utilize it to align your cells and maintain them set up.
Adhere. Stick all the batteries together with your speedy drying adhesive to These are in order and aligned properly.
Flux. Make use of your flux now to the link points.
Connection - Make use of your battery bars to attach your cells. You will need to heat up your soldering gun and heat up the battery bar. Utilizing the bar guards the battery and when the flux begins to bubble, you hire your use of solder. The intention is not to heat the battery by itself. Heating the battery is not just counterproductive, since if you injury the battery it is not going to get the job done, and also dangerous as the cell may possibly explode if overheated.
You will need to complete exactly the same methods for that remaining battery connections. You might be connecting the unfavorable for the beneficial time and again all over again. You can expect to then be ready to connect wiring to your battery pack.
The wires have to be pre-tinned which imply you have to strip off a quarter inch in the protective plastic wiring sheath, make use of the flux to wash them - utilize the flux liberally - warmth your solder gun then heat the wire and stream the solder in to the wire until comprehensively saturated. You may also want solder within the batteries And so the solder will act given that the connector Along with the battery.
As soon as the two, six cell battery packs are comprehensive, you will need to make use of the shrink wrap to safe them - and you will have your full battery pack! Now you'll be able to ability and fly your RC helicopter, aircraft, boat, automobile or truck with no troubles!
