Making an RC Battery Pack - A Essential How-To
If you like RC, you realize the value of a battery pack. The sort of batteries you select, how properly your pack is assembled and how efficiently you demand them are all significant areas to powering your RC vehicle. Positive, you can buy a battery pack pre-assembled, but you can also Construct your own private and obtain the pleasure of coming up with and powering your individual car or truck.
The first thing you'll want to do is when you decide to put collectively a battery pack is what you are powering and just how much juice you may need. You furthermore mght want to consider the next:
one. Think about the chassis of your respective auto. The sort of motor vehicle won't subject about the amount of Room by which You must maneuver. The batteries may have to be oriented inside of a flat pack, a Automated Guided Vehicles (AGV) Battery clustered pack or as both of those. It's also wise to think about the distribution of pounds inside your car or truck - whether or not the battery weight will probably be distributed inside a facet to facet or back to entrance method. In some instances your chassis House for the battery pack is not adaptable, so know about those constraints Before you begin.
2. Think about the motor powering your RC vehicle. Depending upon the electrical power specifications, you'll be able to establish the number of batteries or cells you need. This really is also if you can make your mind up the kind of batteries you can use - if you wish to keep the NiMH batteries or upgrade to LiPo.
three. Figuring out your voltage can be a easy matter of addition. An ordinary mobile voltage is 1.2v, so wired inside of a collection - twelve batteries will incorporate as much as 14.4v - which might ability an fourteen.4 volt RC electric motor.
Future, You will need to assemble your battery pack provides - so Here is a sample browsing listing. Don't forget, we are assuming we're creating a battery pack with fourteen.4v, as in the instance earlier mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you may purchase battery bars in bulk if you propose to make more than one pack and save $)
o Wire: You'll be wanting a greater quality twelve gage which has a superior strand depend. Such a wire, Using these qualities might be more adaptable which is good and remaining extra productive for electricity transmission.
o 80-100 Watt Soldering Gun. You will need a gun as you could be more specific and quicker - this is critical because of the warmth sensitivity of batteries. The quicker and much more specific you may be, the less likely You will be to break the battery.
o sixty/forty Solder. That is better excellent - also essential for swift and exact perform and preventing battery hurt.
o Flux. This is a chemical cleansing agent that eliminates oxidation from metal to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will likely be used to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries correctly and aid a tidy battery pack. The batteries find yourself generally searching like cord Wooden - tidily bundled.
o Soldering "Encouraging Hands" - optional. These units let you maintain issues in position As you solder.
o One more optional timesaver is to get a "Serving to Fingers" accent on 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 resources will help you tackle, strip and thoroughly Lower your twelve gage wire.
o The ultimate component could be the shrink wrap that may go round the overall assembly and maintain it tidy. You will also have to have a heat gun to heat and shrink the wrap.
So, you have discovered how to orient your batteries and what number of you will need - now you receive to operate on assembly. For this example, we're assembling twelve battery cells - six down a person side and 6 down another.
When you determine exactly where the batteries are going in relation in your chassis And just how they're going to get laid out, you may start. For this instance, for example we are doing 6 down one facet and six down another side.
Just to make sure we're on precisely the same page, the final word goal here is to become jogging wire from the good terminal of your respective initial battery for the optimistic terminal on the electrical RC motor after which you can functioning a wire from the adverse terminal on the final battery inside your pack for the constructive terminal of the other battery pack, thus developing a finished circuit.
This signify you might want to have ample wire to reach through the optimistic terminal of one's to start with battery to that terminal and Also in the unfavorable to complete the circuit together with your other battery pack so bear that in mind.
Orientation. Align your initially mobile to make sure that good is pointing "upwards" and unfavorable is pointing "downwards" after which reverse the subsequent battery so It truly is opposite on down the road. If you bought the battery assembly jig, This is certainly whenever you'd utilize it to align your cells and hold them in place.
Adhere. Stick all the batteries together with your fast drying adhesive to They may be if you want and aligned properly.
Flux. Use your flux now over the relationship details.
Link - Use your battery bars to attach your cells. You will need to warmth up your soldering gun and heat up the battery bar. Using the bar shields the battery and if the flux begins to bubble, you use your utilization of solder. The purpose is not to heat the battery alone. Heating the battery is don't just counterproductive, since for those who damage the battery it is not going to do the job, and also risky because the cell may explode if overheated.
You'll want to accomplish precisely the same techniques for your remaining battery connections. You're connecting the damaging to the optimistic again and again once more. You'll then be Prepared to attach wiring for your battery pack.
The wires have to be pre-tinned which suggest you need to strip off a quarter inch on the protective plastic wiring sheath, use the flux to clean them - apply the flux liberally - heat your solder gun and then warmth the wire and movement the solder in the wire until finally comprehensively saturated. You are going to also want solder to the batteries so the solder will act because the connector Along with the battery.
Once the two, 6 cell battery packs are total, you'll want to make use of the shrink wrap to protected them - and you will have your finish battery pack! Now you'll electrical power and fly your RC helicopter, aircraft, boat, automobile or truck without issues!
