Making an RC Battery Pack - A Standard How-To
If you love RC, you recognize the significance of a battery pack. The kind of batteries you choose, how well your pack is assembled and how successfully you charge them are all critical features to powering your RC automobile. Absolutely sure, you can buy a battery pack pre-assembled, but You may as well Establish your individual and acquire the satisfaction of coming up with and powering your own automobile.
The very first thing you need to do is when you select Automated Guided Vehicles (AGV) Battery To place alongside one another a battery pack is what you are powering and how much juice you would like. You also have to have to think about the subsequent:
one. Consider the chassis within your motor vehicle. The kind of automobile would not issue as much as the amount of Area in which You should maneuver. The batteries might have to be oriented within a flat pack, a clustered pack or as equally. It's also wise to think about the distribution of weight within your car or truck - whether or not the battery excess weight will probably be distributed inside a side to aspect or back to front fashion. In some cases your chassis Place for the battery pack isn't adaptable, so be familiar with These constraints before you start.
two. Think about the motor powering your RC motor vehicle. According to the ability necessities, you'll determine what number of batteries or cells you require. This is certainly also once you can determine the sort of batteries you will use - if you'd like to keep the NiMH batteries or enhance to LiPo.
three. Analyzing your voltage is really a simple make any difference of addition. An ordinary mobile voltage is one.2v, so wired in the collection - 12 batteries will insert as much as 14.4v - which would electric power an fourteen.4 volt RC electric powered motor.
Up coming, You'll have to collect your battery pack materials - so here's a sample browsing checklist. Try to remember, we are assuming we're creating a battery pack with 14.4v, as in the example earlier mentioned:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to order battery bars in bulk if you intend to build multiple pack and conserve $)
o Wire: You'll want a greater quality twelve gage which has a substantial strand count. Such a wire, Using these characteristics will be additional flexible which is right in addition to remaining extra productive for electrical power transmission.
o 80-100 Watt Soldering Gun. You'll be wanting a gun since you is often much more correct and more quickly - this is necessary due to warmth sensitivity of batteries. The quicker and more particular you can be, the more unlikely you'll be to wreck the battery.
o 60/forty Solder. This is certainly increased excellent - also crucial for brief and accurate perform and steering clear of battery injury.
o Flux. This 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 might be utilized to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries properly and aid a tidy battery pack. The batteries end up basically on the lookout like wire Wooden - tidily bundled.
o Soldering "Aiding Fingers" - optional. These gadgets assist you to hold items set up When you solder.
o Yet another optional timesaver is to obtain a "Helping Palms" accent in your soldering station.
o Multi Meter. You'll need a excellent multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will allow you to deal with, strip and effectively Minimize your twelve gage wire.
o The ultimate part could be the shrink wrap which is able to go round the entire assembly and hold it tidy. You can also require a warmth gun to heat and shrink the wrap.
So, you've got identified how to orient your batteries and how many you will need - now you obtain to work on assembly. For this instance, we're assembling twelve battery cells - six down one aspect and six down the opposite.
After you detect the place the batteries are heading in relation to the chassis And just how they're going for being laid out, you'll be able to commence. For this example, as an instance we are undertaking six down just one aspect and six down one other facet.
Just to ensure we're on the same web site, the final word goal here is for being operating wire in the optimistic terminal of one's first battery to the constructive terminal on the electrical RC motor and after that running a wire in the adverse terminal on the last battery as part of your pack on the beneficial terminal of your other battery pack, thereby creating a finished circuit.
This suggest you need to have adequate wire to achieve through the favourable terminal of the initial battery to that terminal and Furthermore through the detrimental to finish the circuit with your other battery pack so bear that in mind.
Orientation. Align your initial cell so that positive is pointing "upwards" and damaging is pointing "downwards" after which you can reverse the next battery so it's opposite on down the line. If you purchased the battery assembly jig, This really is any time you'd use it to align your cells and maintain them in position.
Adhere. Adhere each of the batteries along with your fast drying adhesive to they are in order and aligned thoroughly.
Flux. Make use of your flux now to the connection factors.
Link - Make use of your battery bars to attach your cells. You will need to warmth up your soldering gun and heat up the battery bar. Utilizing the bar shields the battery and once the flux begins to bubble, you hire your usage of solder. The aim is to NOT heat the battery by itself. Heating the battery is don't just counterproductive, since should you harm the battery it will never operate, but additionally risky because the mobile might explode if overheated.
You'll be wanting to complete the identical actions for your remaining battery connections. You're connecting the unfavorable on the good repeatedly all over again. You may then be Completely ready to connect wiring towards your battery pack.
The wires have to be pre-tinned which signify you might want to strip off 1 / 4 inch in the protecting plastic wiring sheath, utilize the flux to scrub them - utilize the flux liberally - warmth your solder gun and after that warmth the wire and stream the solder into your wire right up until comprehensively saturated. You will also want solder on the batteries Therefore the solder will act because the connector Together with the battery.
Once the two, six mobile battery packs are finish, you'll want to make use of the shrink wrap to secure them - and you will have your complete battery pack! Now you can electricity and fly your RC helicopter, plane, boat, car or truck without any troubles!
