Building an RC Battery Pack - A Standard How-To
If you love RC, you already know the importance of a battery pack. The sort of batteries you select, how nicely your pack is assembled And the way proficiently you demand them are all essential areas to powering your RC vehicle. Positive, You should buy a battery pack pre-assembled, but You may also Develop your own personal and acquire the satisfaction of coming up with and powering your very own car or truck.
The first thing you'll want to do is when you decide to put alongside one another a battery pack is what you're powering and the amount juice you need. You furthermore mght will need to think about the next:
1. Think about the chassis of your respective vehicle. The type of car won't issue just as much as the amount of Room in which you have to maneuver. The batteries could need to be oriented inside of a flat pack, a clustered pack or as both. It's also wise to think about the distribution of excess weight in the motor vehicle - whether or not the battery bodyweight will probably be distributed inside a facet to facet or again to entrance manner. Sometimes your chassis House for any battery pack isn't adaptable, so know about These constraints Before you begin.
two. Look at the motor powering your RC vehicle. Depending on the electric power requirements, you'll be able to figure out the amount of batteries or cells you will need. This is certainly also when you can decide the sort of batteries you will use - if you'd like to maintain your NiMH batteries or improve to LiPo.
3. Deciding your voltage is known as a very simple matter of addition. A normal mobile voltage is one.2v, so wired in the sequence - 12 batteries will add nearly 14.4v - which might power an 14.4 volt RC electric powered motor.
Following, You'll have to gather your battery pack provides - so This is a sample procuring checklist. Remember, we are assuming we're creating a battery pack with 14.4v, as in the example higher than:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you may order battery bars in bulk if you propose to make more than one pack and save $)
o Wire: You will need an increased good quality twelve gage having a large strand rely. This kind of wire, with these attributes are going to be far more adaptable which is ideal and being additional efficient for ability transmission.
o eighty-100 Watt Soldering Gun. You'll be wanting a gun because you may be more precise and more rapidly - this is essential due to warmth sensitivity of batteries. The faster and even more distinct you'll be able to be, the not as likely You will be to damage the battery.
o sixty/forty Solder. This is certainly increased top quality - also essential for speedy and correct get the job done and avoiding battery hurt.
o Flux. It is a chemical cleansing agent that removes oxidation from metallic to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive is going to be accustomed to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries properly and facilitate a tidy battery pack. The batteries find yourself fundamentally looking like twine Wooden - tidily bundled.
o Soldering "Encouraging Fingers" - optional. These gadgets permit you to keep matters in position while you solder.
o A further optional timesaver is to acquire a "Helping Palms" accent to your soldering station.
o Multi Meter. You need a excellent multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools can assist you deal with, strip and effectively Slash your 12 gage wire.
o The final element could be the shrink wrap which will go throughout the complete assembly and keep it tidy. You'll also need a heat gun to warmth and shrink the wrap.
So, you've got determined how you can orient your batteries and the number of you require - now you will get to operate on assembly. For this instance, we are assembling 12 battery cells - 6 down a person aspect and 6 down one other.
Once you determine exactly where the batteries are heading in relation for your chassis and how they are going to be laid out, you could start out. For this example, to illustrate we are executing six down one particular facet and 6 down one other aspect.
Just to be sure we're on the same web page, the ultimate purpose here is to become running wire within the optimistic terminal of your initially battery on the good terminal on the electrical RC motor and afterwards jogging a wire from the detrimental terminal on the final battery within your pack for the optimistic terminal of the other battery pack, thus developing a finished circuit.
This signify you'll want to have enough wire to achieve through the beneficial terminal of one's first battery to that terminal and likewise within the negative to finish the circuit with the other battery pack so bear that in your mind.
Orientation. Align your first cell to ensure positive is pointing "upwards" and negative is pointing "downwards" and then reverse the following battery so it's reverse on down the line. If you purchased the battery assembly jig, This really is after you'd use it to align your cells and keep them in position.
Adhere. Adhere every one of the batteries along with your quick drying adhesive to They may be so as and aligned correctly.
Flux. Make use of your flux now about the relationship factors.
Connection - Make use of your battery bars to attach your cells. You will need to heat up your soldering gun and warmth up the battery bar. Utilizing the bar safeguards the battery and once the flux begins to bubble, you Automated Guided Vehicles (AGV) Battery use your utilization of solder. The purpose is not to warmth the battery alone. Heating the battery is not merely counterproductive, given that in the event you destruction the battery it won't perform, but in addition dangerous since the mobile may possibly explode if overheated.
You'll be wanting to finish the exact same techniques to the remaining battery connections. You're connecting the detrimental towards the optimistic again and again once again. You can expect to then be Prepared to attach wiring on your battery pack.
The wires have to be pre-tinned which signify you must strip off 1 / 4 inch from the protective plastic wiring sheath, utilize the flux to wash them - utilize the flux liberally - heat your solder gun and after that warmth the wire and movement the solder into your wire until totally saturated. You'll also want solder about the batteries Therefore the solder will act as being the connector Along with the battery.
When the two, six mobile battery packs are full, you will need to utilize the shrink wrap to secure them - and you'll have your entire battery pack! Now you can ability and fly your RC helicopter, airplane, boat, vehicle or truck without having challenges!
