Making an RC Battery Pack - A Simple How-To
If you love RC, you already know the necessity of a battery pack. The sort of batteries you decide on, how nicely your pack is assembled And the way proficiently you cost them are all essential areas to powering your RC car. Positive, you can buy a battery pack pre-assembled, but You may as well build your own personal and obtain the fulfillment of planning and powering your personal car.
The very first thing you have to do is when you decide to put together a battery pack is what you are powering and the amount juice you would like. You furthermore may need to have to consider the following:
one. Think about the chassis of your motor vehicle. The sort of vehicle would not make a difference as much as the amount of Room through which You will need to maneuver. The batteries could need to be oriented inside a flat pack, a clustered pack or as both equally. It's also advisable to contemplate the distribution of weight in your Automated Guided Vehicles (AGV) Battery car or truck - whether the battery fat will likely be distributed in a side to facet or back again to front method. Sometimes your chassis space for your battery pack is not adaptable, so be aware of All those constraints Before you begin.
2. Consider the motor powering your RC vehicle. Based on the electrical power necessities, you can identify the amount of batteries or cells you would like. That is also when you can choose the sort of batteries you may use - if you want to keep the NiMH batteries or update to LiPo.
3. Pinpointing your voltage is known as a very simple make any difference of addition. A typical cell voltage is one.2v, so wired in a series - 12 batteries will insert up to 14.4v - which would electric power an 14.four volt RC electric motor.
Following, You'll have to assemble your battery pack supplies - so here's a sample searching list. Keep in mind, we are assuming we are developing a battery pack with fourteen.4v, as in the example above:
o twelve Batteries or Battery Cells
o twelve Battery Bars (you may order battery bars in bulk if you intend to develop multiple pack and help save $)
o Wire: You'll be wanting an increased top quality 12 gage which has a superior strand rely. Such a wire, Using these qualities will be more flexible which is right along with currently being much more effective for ability transmission.
o 80-a hundred Watt Soldering Gun. You will need a gun since you can be much more actual and a lot quicker - this is critical due to the warmth sensitivity of batteries. The speedier plus more particular you could be, the less likely you'll be to wreck the battery.
o sixty/forty Solder. This really is bigger excellent - also crucial for fast and exact work and preventing battery destruction.
o Flux. This can be a chemical cleaning agent that gets rid of oxidation from metal to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive is going to be used to bundle the batteries with each other.
o Battery Pack Assembly Jig - optional. These assembly devices align the batteries effectively and facilitate a tidy battery pack. The batteries end up generally looking like twine wood - tidily bundled.
o Soldering "Serving to Fingers" - optional. These units permit you to keep items set up When you solder.
o An additional optional timesaver is to get a "Supporting Hands" accessory for the soldering station.
o Multi Meter. You will need a fantastic multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools will assist you to manage, strip and properly Minimize your 12 gage wire.
o The ultimate ingredient would be the shrink wrap that may go across the full assembly and retain it tidy. You'll also require a warmth gun to warmth and shrink the wrap.
So, you've determined the best way to orient your batteries and the quantity of you will need - now you have to operate on assembly. For this example, we're assembling twelve battery cells - six down 1 facet and six down the opposite.
As soon as you detect the place the batteries are heading in relation for your chassis and how they are going to become laid out, you may commence. For this example, as an instance we're executing 6 down one side and 6 down the opposite facet.
Just to make sure we're on exactly the same website page, the final word intention Here's to become working wire with the constructive terminal of your respective to start with battery on the good terminal on the electrical RC motor then functioning a wire from your adverse terminal on the last battery within your pack to your optimistic terminal of one's other battery pack, thus creating a finished circuit.
This necessarily mean you must have ample wire to succeed in from your favourable terminal of the very first battery to that terminal and Also within the adverse to complete the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your to start with mobile to make sure that constructive is pointing "upwards" and detrimental is pointing "downwards" and afterwards reverse the subsequent battery so It truly is reverse on down the line. If you purchased the battery assembly jig, This is often any time you'd utilize it to align your cells and maintain them set up.
Adhere. Stick all the batteries along with your rapidly drying adhesive to They're as a way and aligned properly.
Flux. Make use of your flux now around the relationship points.
Relationship - Use your battery bars to attach your cells. You will need to heat 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 not to heat the battery itself. Heating the battery is not merely counterproductive, due to the fact should you damage the battery it will never do the job, but will also hazardous since the cell may possibly explode if overheated.
You'll be wanting to complete a similar ways for your remaining battery connections. You will be connecting the detrimental on the optimistic repeatedly all over again. You can expect to then be All set to connect wiring for your battery pack.
The wires must be pre-tinned which imply you must strip off 1 / 4 inch in the protecting plastic wiring sheath, utilize the flux to scrub them - implement the flux liberally - heat your solder gun and afterwards warmth the wire and movement the solder into the wire until finally completely saturated. You can expect to also want solder about the batteries Hence the solder will act as being the connector Using the battery.
As soon as the two, 6 cell battery packs are total, you'll be wanting to employ the shrink wrap to protected them - and you'll have your full battery pack! Now you'll ability and fly your RC helicopter, aircraft, boat, auto or truck with no troubles!
