Making an RC Battery Pack - A Standard How-To
If you like RC, you understand the importance of a battery pack. The sort of batteries you select, how nicely your pack is assembled And the way efficiently you cost them are all critical areas to powering your RC vehicle. Positive, You should buy a battery pack pre-assembled, but You may as well Construct your own private and acquire the gratification of Automated Guided Vehicles (AGV) Battery coming up with and powering your very own car or truck.
The very first thing you have to do is when you choose To place together a battery pack is what you are powering and the amount of juice you may need. You furthermore mght need to have to think about the subsequent:
1. Think about the chassis of the vehicle. The sort of motor vehicle isn't going to matter about the quantity of space in which You need to maneuver. The batteries may well must be oriented in a flat pack, a clustered pack or as both. It's also wise to think about the distribution of pounds in the car or truck - whether or not the battery pounds will be dispersed in a facet to aspect or again to entrance method. Occasionally your chassis Place for any battery pack is not adaptable, so be familiar with Those people constraints Before you begin.
2. Consider the motor powering your RC motor vehicle. Depending upon the energy requirements, you'll be able to establish the number of batteries or cells you may need. This can be also once you can come to a decision the kind of batteries you will use - if you need to maintain your NiMH batteries or upgrade to LiPo.
three. Analyzing your voltage is really a basic issue of addition. A regular cell voltage is one.2v, so wired in a very series - twelve batteries will include approximately 14.4v - which would energy an fourteen.four volt RC electric motor.
Upcoming, You will need to assemble your battery pack supplies - so here's a sample browsing checklist. Remember, we're assuming we're developing a battery pack with fourteen.4v, as in the instance above:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you are able to purchase battery bars in bulk if you intend to make more than one pack and help save $)
o Wire: You will need a greater quality 12 gage having a superior strand count. This type of wire, with these attributes might be a lot more versatile which is good together with currently being more economical for power transmission.
o eighty-a hundred Watt Soldering Gun. You'll be wanting a gun as you might be far more exact and a lot quicker - this is essential because of the warmth sensitivity of batteries. The quicker and a lot more particular you could be, the not as likely you'll be to wreck the battery.
o 60/forty Solder. This can be better quality - also significant for fast and exact operate and keeping away from battery hurt.
o Flux. It is a chemical cleansing agent that removes oxidation from metallic to aid soldering. You need to use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will likely be accustomed to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries properly and facilitate a tidy battery pack. The batteries find yourself basically hunting like twine wood - tidily bundled.
o Soldering "Assisting Palms" - optional. These products let you keep things in place When you solder.
o A different optional timesaver is to acquire a "Supporting Palms" accent for your personal soldering station.
o Multi Meter. You'll need a good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will assist you to take care of, strip and adequately Minimize your twelve gage wire.
o The final ingredient may be the shrink wrap that can go throughout the full assembly and preserve it tidy. You'll also need a warmth gun to warmth and shrink the wrap.
So, you have identified tips on how to orient your batteries and how many you would like - now you get to work on assembly. For this example, we are assembling 12 battery cells - six down just one facet and 6 down the opposite.
After you identify the place the batteries are going in relation on your chassis And just how they're going to get laid out, you are able to commence. For this example, as an instance we are executing 6 down one particular aspect and six down the other aspect.
Just to be sure we're on the same website page, the last word goal Here's being managing wire with the good terminal of your respective first battery into the constructive terminal on the electric RC motor after which functioning a wire from the negative terminal on the final battery within your pack on the beneficial terminal of your respective other battery pack, therefore making a finished circuit.
This indicate you might want to have sufficient wire to succeed in through the favourable terminal of your first battery to that terminal and Furthermore within the detrimental to accomplish the circuit with all your other battery pack so bear that in your mind.
Orientation. Align your first cell so that constructive is pointing "upwards" and adverse is pointing "downwards" after which you can reverse the following battery so it's opposite on down the road. If you bought the battery assembly jig, this is after you'd use it to align your cells and keep them in position.
Adhere. Stick the many batteries together with your quick drying adhesive to they are as a way and aligned appropriately.
Flux. Make use of your flux now on the connection details.
Link - Use your battery bars to connect your cells. You'll need to heat up your soldering gun and heat up the battery bar. Utilizing the bar safeguards the battery and when the flux begins to bubble, you employ your usage of solder. The purpose is to NOT heat the battery alone. Heating the battery is not merely counterproductive, considering the fact that should you destruction the battery it will never perform, but in addition perilous as the cell could explode if overheated.
You will need to finish the exact same methods for your remaining battery connections. You might be connecting the negative into the favourable time and again once more. You may then be ready to connect wiring on your battery pack.
The wires must be pre-tinned which signify you might want to strip off 1 / 4 inch with the protective plastic wiring sheath, utilize the flux to scrub them - apply the flux liberally - warmth your solder gun then heat the wire and move the solder into your wire until eventually totally saturated. You are going to also want solder on the batteries Therefore the solder will act given that the connector While using the battery.
After the two, six mobile battery packs are comprehensive, you'll be wanting to employ the shrink wrap to safe them - and you'll have your total battery pack! Now you'll be able to electrical power and fly your RC helicopter, airplane, boat, vehicle or truck without having challenges!
