Making an RC Battery Pack - A Standard How-To
If you love RC, you already know the value of a battery pack. The sort of batteries you end up picking, how nicely your pack is assembled And exactly how proficiently you charge them are all important areas to powering your RC auto. Sure, You should buy a battery pack pre-assembled, but you can also Make your own private and get the gratification of designing and powering your own car or truck.
The first thing you'll want to do is when you choose To place jointly a battery pack is what you are powering and simply how much juice you need. You furthermore may require to consider the following:
1. Think about the chassis within your auto. The sort of automobile won't issue just as much as the quantity of Area in which You will need to maneuver. The batteries may possibly have to be oriented inside a flat pack, a clustered pack or as equally. It's also wise to think about the distribution of fat with your motor vehicle - if the battery weight will probably be distributed in the facet to side or back to front way. In some instances your chassis Place to get a battery pack isn't Automated Guided Vehicles (AGV) Battery adaptable, so be familiar with those constraints before you start.
two. Consider the motor powering your RC motor vehicle. Depending upon the electrical power specifications, you'll be able to determine how many batteries or cells you require. This really is also once you can determine the type of batteries you can expect to use - if you need to maintain your NiMH batteries or upgrade to LiPo.
three. Figuring out your voltage is known as a uncomplicated make any difference of addition. A regular mobile voltage is one.2v, so wired in a very collection - twelve batteries will include nearly 14.4v - which might electrical power an fourteen.4 volt RC electric powered motor.
Upcoming, you'll need to assemble your battery pack provides - so here's a sample searching list. Try to remember, we are assuming we are making a battery pack with 14.4v, as in the example higher than:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you could get battery bars in bulk if you propose to create more than one pack and save $)
o Wire: You will need an increased top quality 12 gage that has a significant strand depend. Such a wire, Using these attributes is going to be additional adaptable which is right as well as remaining a lot more effective for electric power transmission.
o eighty-a hundred Watt Soldering Gun. You will need a gun because you could be far more actual and more rapidly - this is necessary as a result of warmth sensitivity of batteries. The more rapidly plus more precise it is possible to be, the more unlikely you'll be to wreck the battery.
o sixty/forty Solder. This can be bigger high-quality - also significant for quick and exact function and avoiding battery damage.
o Flux. This is the chemical cleaning agent that eliminates oxidation from steel to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive are going to be accustomed to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries correctly and aid a tidy battery pack. The batteries turn out essentially seeking like wire Wooden - tidily bundled.
o Soldering "Helping Hands" - optional. These units allow you to keep factors in position Whilst you solder.
o One more optional timesaver is to get a "Helping Hands" accent for the soldering station.
o Multi Meter. You'll need a fantastic multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will help you tackle, strip and properly cut your 12 gage wire.
o The final element could be the shrink wrap which will go throughout the complete assembly and maintain it tidy. You can also require a heat gun to warmth and shrink the wrap.
So, you've discovered the way to orient your batteries and the quantity of you need - now you obtain to work on assembly. For this example, we're assembling 12 battery cells - six down a single aspect and 6 down one other.
When you recognize the place the batteries are going in relation towards your chassis And just how they are going to generally be laid out, you can get started. For this example, as an instance we are doing 6 down a single facet and 6 down the opposite side.
Just to be sure we're on exactly the same website page, the last word target Here's to generally be operating wire through the favourable terminal of your 1st battery to your positive terminal on the electrical RC motor and then running a wire from the unfavorable terminal on the last battery in the pack for the good terminal within your other battery pack, thereby making a finished circuit.
This necessarily mean you'll want to have sufficient wire to achieve within the optimistic terminal of one's first battery to that terminal and likewise from the detrimental to complete the circuit with all your other battery pack so bear that in mind.
Orientation. Align your 1st mobile to ensure positive is pointing "upwards" and negative is pointing "downwards" and after that reverse another battery so It really is opposite on down the road. If you bought the battery assembly jig, This can be any time you'd utilize it to align your cells and keep them set up.
Adhere. Adhere each of the batteries together with your quickly drying adhesive to they are to be able and aligned effectively.
Flux. Make use of your flux now around the connection points.
Connection - Make use of your battery bars to connect your cells. You will need to warmth up your soldering gun and heat up the battery bar. Using the bar safeguards the battery and in the event the flux begins to bubble, you make use of your use of solder. The objective is to NOT heat the battery by itself. Heating the battery is not simply counterproductive, given that in case you hurt the battery it would not perform, but also hazardous since the cell may well explode if overheated.
You'll want to complete the same steps with the remaining battery connections. You will be connecting the destructive into the beneficial again and again again. You will then be ready to attach wiring for your battery pack.
The wires should be pre-tinned which imply you need to strip off a quarter inch of the protective plastic wiring sheath, make use of the flux to clean them - implement the flux liberally - heat your solder gun and afterwards warmth the wire and circulation the solder in the wire until finally totally saturated. You can expect to also want solder to the batteries And so the solder will act as the connector Using the battery.
When the two, 6 mobile battery packs are total, you'll be wanting to utilize the shrink wrap to protected them - and you'll have your full battery pack! Now you'll be able to electrical power and fly your RC helicopter, plane, boat, automobile or truck without complications!
