Constructing an RC Battery Pack - A Primary How-To
If you like RC, you already know the value of a battery pack. The type of batteries you decide on, how very well your pack is assembled And exactly how proficiently you cost them are all critical facets to powering your RC motor vehicle. Positive, You should buy a battery pack pre-assembled, but you can also build your personal and have the gratification of designing and powering your personal auto.
The first thing you have to do is when you choose to put with each other a battery pack is what you're powering and exactly how much juice you require. In addition, you have to have to consider the next:
1. Consider the chassis of your auto. The sort of automobile doesn't issue around the level of Area during which you have to maneuver. The batteries may should be oriented in a very flat pack, a clustered pack or as both of those. You should also consider the distribution of bodyweight with your motor vehicle - if the battery bodyweight will likely be distributed inside a facet to facet or back again to front method. Occasionally your chassis House to get a battery pack will not be adaptable, so be aware of These constraints Before you begin.
two. Look at the motor powering your RC motor vehicle. With regards to the energy prerequisites, you'll decide the number of batteries or cells you need. This is also after you can choose Automated Guided Vehicles (AGV) Battery the kind of batteries you will use - if you would like maintain your NiMH batteries or up grade to LiPo.
three. Determining your voltage is mostly a simple matter of addition. A normal mobile voltage is one.2v, so wired inside of a sequence - 12 batteries will increase up to fourteen.4v - which might power an fourteen.4 volt RC electric motor.
Future, You will need to collect your battery pack materials - so This is a sample shopping record. Recall, we are assuming we are developing a battery pack with 14.4v, as in the example earlier mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you are able to order battery bars in bulk if you intend to make multiple pack and help you save $)
o Wire: You'll want a higher top quality 12 gage using a high strand rely. This kind of wire, with these features will be additional versatile which is good as well as being extra efficient for energy transmission.
o 80-100 Watt Soldering Gun. You'll be wanting a gun because you can be extra exact and quicker - this is necessary due to the warmth sensitivity of batteries. The quicker and much more specific you can be, the less likely you'll be to break the battery.
o sixty/forty Solder. This is certainly greater high quality - also essential for quick and correct function and avoiding battery hurt.
o Flux. This can be a chemical cleaning agent that removes oxidation from steel to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapidly drying adhesive are going to be utilized to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries correctly and aid a tidy battery pack. The batteries wind up basically searching like twine Wooden - tidily bundled.
o Soldering "Serving to Fingers" - optional. These gadgets enable you to maintain items in position When you solder.
o A further optional timesaver is to secure a "Helping Hands" accent on your soldering station.
o Multi Meter. You need a very good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These applications can assist you tackle, strip and appropriately Lower your twelve gage wire.
o The final element will be the shrink wrap that will go across the full assembly and keep it tidy. You'll also have to have a heat gun to warmth and shrink the wrap.
So, you have determined the best way to orient your batteries and what number of you require - now you obtain to work on assembly. For this example, we are assembling twelve battery cells - six down a person aspect and six down another.
When you recognize where the batteries are heading in relation on your chassis and how they are going to generally be laid out, you can begin. For this example, for instance we're undertaking six down a person side and six down the other side.
Just to make certain we're on exactly the same page, the final word intention here is for being functioning wire in the constructive terminal of the 1st battery into the constructive terminal on the electrical RC motor after which you can working a wire with the damaging terminal on the last battery as part of your pack towards the constructive terminal of the other battery pack, therefore developing a accomplished circuit.
This mean you'll want to have ample wire to achieve through the beneficial terminal within your first battery to that terminal and likewise within the adverse to accomplish the circuit with the other battery pack so bear that in your mind.
Orientation. Align your first mobile to ensure constructive is pointing "upwards" and adverse is pointing "downwards" and after that reverse another battery so it's reverse on down the road. If you bought the battery assembly jig, This is certainly any time you'd utilize it to align your cells and hold them in position.
Adhere. Adhere all of the batteries together with your rapid drying adhesive to They're in order and aligned effectively.
Flux. Use your flux now on the relationship points.
Link - Make use of your battery bars to attach your cells. You'll have to warmth up your soldering gun and warmth up the battery bar. Using the bar shields the battery and once the flux begins to bubble, you hire your use of solder. The purpose is not to heat the battery alone. Heating the battery is not only counterproductive, due to the fact for those who destruction the battery it won't work, but in addition hazardous since the mobile could possibly explode if overheated.
You'll be wanting to accomplish precisely the same methods for that remaining battery connections. You will be connecting the negative for the constructive over and over again. You can then be ready to connect wiring to your battery pack.
The wires must be pre-tinned which signify you must strip off a quarter inch in the protective plastic wiring sheath, use the flux to wash them - use the flux liberally - heat your solder gun and then warmth the wire and flow the solder to the wire right until totally saturated. You are going to also want solder around the batteries Hence the solder will act as being the connector Along with the battery.
When the two, six cell battery packs are total, you'll be wanting to employ the shrink wrap to safe them - and you will have your entire battery pack! Now you'll be able to electric power and fly your RC helicopter, aircraft, boat, car or truck without any challenges!
