Building an RC Battery Pack - A Basic How-To
If you like RC, you understand the value of a battery pack. The sort of batteries you select, how properly your pack is assembled And the way successfully you cost them are all vital factors to powering your RC motor vehicle. Absolutely sure, You should purchase a battery pack pre-assembled, but you can also Develop your own private and get the pleasure of building and powering your individual auto.
The first thing you have to do is when you choose to put collectively a battery pack is what you're powering and the amount of juice you require. Additionally you need to consider the following:
1. Look at the chassis of the vehicle. The kind of vehicle will not issue about the amount of Area wherein You need to maneuver. The batteries could must be oriented in a flat pack, a clustered pack or as each. You should also give thought to the distribution of weight inside your car or truck - whether the battery excess weight will be distributed in a facet to side or again to entrance way. Occasionally your chassis Place for the battery pack will not be adaptable, so know about All those constraints Before you begin.
2. Look at the motor powering your RC car. Depending on the power requirements, you can identify how many batteries or cells you need. This can be also if you can decide the type of batteries you may use - if you would like maintain your NiMH batteries or enhance to LiPo.
3. Deciding your voltage is mostly a simple make any difference of addition. A regular cell voltage is 1.2v, so wired in a very collection - twelve batteries will insert nearly 14.4v - which might energy an 14.four volt RC electric motor.
Following, you'll need to gather your battery pack materials - so Here is a sample procuring listing. Recall, we're assuming we are creating a battery pack with 14.4v, as in the instance above:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you can get battery bars in bulk if you intend to construct multiple pack and help you save $)
o Wire: You'll be wanting a better good quality 12 gage having a high strand count. This type of wire, Using these properties might be additional adaptable which is right in addition to staying a lot more efficient for energy transmission.
o eighty-100 Watt Soldering Gun. You will need a gun since you might be additional specific and quicker - this is essential due to the heat sensitivity of batteries. The a lot quicker and even more particular you may be, the more unlikely You will be to break the battery.
o 60/forty Solder. That is better quality - also significant for rapid and precise work and staying away from battery damage.
o Flux. This is a chemical cleaning agent that eliminates oxidation from steel to facilitate soldering. You can use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapid drying adhesive might be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries appropriately and facilitate a tidy battery pack. The batteries end up generally seeking like wire wood - tidily bundled.
o Soldering "Aiding Hands" - optional. These devices enable you to hold issues in place When you solder.
o Another optional timesaver is to secure a "Helping Hands" accent in your soldering station.
o Multi Meter. You'll need a superior multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These applications will let you take care of, strip and correctly cut your twelve gage wire.
o The ultimate part would be the shrink wrap which can go around the total assembly and hold it tidy. You are going to also require a heat gun to heat and shrink the wrap.
So, you have identified ways to orient your batteries and the amount of you'll need - now you get to work on assembly. For this instance, we're assembling twelve battery cells - six down one side and six down the other.
Once you recognize the place the batteries are heading in relation in your chassis And exactly how they are going to become laid out, you are able to begin. For this instance, as an example we're doing 6 down one particular aspect and six down another side.
Just to make certain we're on the same site, the final word aim Here's to be running wire in the constructive terminal of the 1st battery into the optimistic Automated Guided Vehicles (AGV) Battery terminal on the electric RC motor and afterwards running a wire from the adverse terminal on the last battery as part of your pack on the constructive terminal of the other battery pack, thereby developing a accomplished circuit.
This signify you should have sufficient wire to achieve through the beneficial terminal of your respective to start with battery to that terminal and Similarly within the damaging to complete the circuit together with your other battery pack so bear that in mind.
Orientation. Align your initial cell in order that good is pointing "upwards" and unfavorable is pointing "downwards" and after that reverse the subsequent battery so It is reverse on down the road. If you purchased the battery assembly jig, This is often any time you'd utilize it to align your cells and maintain them in position.
Adhere. Stick every one of the batteries together with your fast drying adhesive to They're as a way and aligned correctly.
Flux. Use your flux now over the relationship points.
Link - 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 shields the battery and once the flux starts to bubble, you use your usage of solder. The target is not to heat the battery by itself. Heating the battery is not merely counterproductive, considering the fact that when you destruction the battery it won't perform, and also risky as the mobile may explode if overheated.
You will need to finish a similar actions for your remaining battery connections. You happen to be connecting the destructive to the optimistic repeatedly all over again. You are going to then be All set to attach wiring to your battery pack.
The wires need to be pre-tinned which suggest you might want to strip off 1 / 4 inch with the protective plastic wiring sheath, utilize the flux to clean them - implement the flux liberally - heat your solder gun and then warmth the wire and movement the solder into your wire until completely saturated. You can also want solder within the batteries And so the solder will act as the connector with the battery.
After the two, 6 mobile battery packs are full, you will need to hire the shrink wrap to protected them - and you will have your full battery pack! Now you can power and fly your RC helicopter, plane, boat, car or truck without any issues!
