Constructing an RC Battery Pack - A Basic How-To If you love RC, you are aware of the necessity of a battery pack. The kind of batteries you choose, how nicely your pack is assembled and how effectively you demand them are all essential aspects to powering your RC vehicle. Guaranteed, you can buy a battery pack pre-assembled, but You can even Develop your individual and have the gratification of creating and powering your own personal car. The first thing you might want to do is when you choose To place alongside one another a battery pack is what you are powering and the amount of juice you would like. You furthermore mght have to have to think about the next: 1. Consider the chassis within your automobile. The kind of automobile will not make any difference around the quantity of Room during which you have to maneuver. The batteries may well have to be oriented in the flat pack, a clustered pack or as both equally. It's also wise to take into consideration the distribution of bodyweight with your car or truck - if the battery weight is going to be dispersed inside a facet to aspect or again to front manner. Occasionally your chassis Room for a battery pack is not really adaptable, so concentrate on These constraints Before you begin. two. Consider the motor powering your RC motor vehicle. Depending on the electric power needs, you'll be able to establish how many batteries or cells you require. This is also whenever you can make your mind up the kind of batteries you can use - if you would like maintain your NiMH batteries or upgrade to LiPo. three. Figuring out your voltage can be a simple subject of addition. A standard cell voltage is 1.2v, so wired within a sequence - twelve batteries will insert around 14.4v - which might ability an fourteen.four volt RC electric motor. Following, You'll have to assemble your battery pack supplies - so here's a sample buying checklist. Don't forget, we are assuming we're developing a battery pack with 14.4v, as in the instance previously mentioned: o twelve Batteries or Battery Cells o twelve Battery Bars (you could purchase battery bars in bulk if you intend to make more than one pack and preserve $) o Wire: You will need the next good quality twelve gage using a higher strand depend. This sort of wire, with these attributes will be additional adaptable which is ideal as well as being a lot more economical for energy transmission. o eighty-a hundred Watt Soldering Gun. You'll be wanting a gun simply because you could be more precise and a lot quicker - this is important as a result of warmth sensitivity of batteries. The more quickly plus more precise you can be, the less likely You will be to break the battery. o 60/forty Solder. This is better high-quality - also crucial for quick and accurate do the job and keeping away from battery problems. o Flux. It is a chemical cleansing agent that gets rid of oxidation from steel to aid soldering. You may use liquid or paste flux when assembling a battery pack. o Shoo Goo or Goop. This rapidly drying adhesive will probably be used to bundle the batteries together. o Battery Pack Assembly Jig - optional. These assembly equipment align the batteries properly and aid a tidy battery pack. The batteries wind up basically seeking like cord wood - tidily bundled. o Soldering "Helping Arms" - optional. These devices permit you to maintain things in place Whilst you solder. o A different optional timesaver is to secure a "Helping Palms" accessory for your soldering station. o Multi Meter. You'll need a fantastic multimeter to check voltage and polarity. o Wire strippers and Wire Cutters. These instruments can assist you tackle, strip and correctly Slash your 12 gage wire. o The ultimate part may be the shrink wrap which can go round the whole assembly and preserve it tidy. You can also need a warmth gun to warmth and shrink the wrap. So, you've got discovered tips on how to orient your batteries and the number of you'll need - now you obtain to work on assembly. For this example, we're assembling twelve battery cells - 6 down one particular facet and six down another. Once you recognize in which the batteries are likely in relation for your chassis And exactly how they are going to become laid out, you can get started. For this example, to illustrate we're accomplishing 6 down 1 side and six down another side. Just to be certain we're on precisely the same webpage, the final word purpose Here's to generally be jogging wire within Automated Guided Vehicles (AGV) Battery the positive terminal of the 1st battery towards the good terminal on the electric RC motor after which working a wire with the negative terminal on the final battery with your pack on the beneficial terminal of one's other battery pack, thereby developing a finished circuit. This indicate you should have sufficient wire to succeed in through the optimistic terminal of your respective to start with battery to that terminal and Furthermore within the destructive to finish the circuit with all your other battery pack so bear that in mind. Orientation. Align your very first cell to ensure optimistic is pointing "upwards" and negative is pointing "downwards" and then reverse the subsequent battery so It really is reverse on down the road. If you bought the battery assembly jig, This really is if you'd use it to align your cells and maintain them set up. Adhere. Stick the many batteries along with your rapidly drying adhesive to They're so as and aligned adequately. Flux. Use your flux now over the connection factors. Connection - 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 protects the battery and when the flux starts to bubble, you hire your usage of solder. The intention is not to heat the battery alone. Heating the battery is not merely counterproductive, considering the fact that should you problems the battery it is not going to perform, but will also risky because the mobile may explode if overheated. You will need to complete precisely the same measures to the remaining battery connections. That you are connecting the damaging for the positive over and over again. You can then be ready to connect wiring to your battery pack. The wires have to be pre-tinned which necessarily mean you have to strip off 1 / 4 inch with the protective plastic wiring sheath, use the flux to wash them - use the flux liberally - heat your solder gun then warmth the wire and flow the solder into your wire until finally carefully saturated. You may also want solder around the batteries And so the solder will act since the connector While using the battery. When the two, 6 cell battery packs are complete, you'll be wanting to use the shrink wrap to protected them - and you will have your total battery pack! Now you'll be able to energy and fly your RC helicopter, aircraft, boat, auto or truck with no complications!
