Making an RC Battery Pack - A Standard How-To
If you like RC, you already know the necessity of a battery pack. The kind of batteries you decide on, how nicely your pack is assembled And just how successfully you demand them are all significant aspects to powering your RC automobile. Sure, you can buy a battery pack pre-assembled, but You can even Establish your very own and have the fulfillment of designing and powering your own personal vehicle.
The first thing you must do is when you select to put collectively a battery pack is what you're powering and exactly how much juice you would like. You also want to consider the following:
1. Consider the chassis of one's car or truck. The type of motor vehicle does not make any difference about the level of Place where You should maneuver. The batteries may possibly must be oriented in a very flat pack, a clustered pack or as both. It's also wise to think about the distribution of fat in your automobile - whether or not the battery bodyweight will probably be dispersed in the side to facet or again to entrance way. Sometimes your chassis space for your battery pack is not really adaptable, so pay attention to Those people constraints before you start.
two. Think about the motor powering your RC motor vehicle. Depending on the energy necessities, you'll be able to figure out the quantity of batteries or cells you need. This is also after you can decide the kind of batteries you'll use - if you want to keep your NiMH batteries or enhance to LiPo.
three. Figuring out your voltage is really a very simple make a difference of addition. A typical cell voltage is 1.2v, so wired inside a series - twelve batteries will increase as many as 14.4v - which would electricity an 14.four volt RC electrical motor.
Subsequent, You will need to assemble your battery pack provides - so Here is a sample browsing list. Recall, we are assuming we are creating a battery pack with fourteen.4v, as in the instance earlier mentioned:
o 12 Batteries or Battery Cells
o twelve Battery Bars (it is possible to purchase battery bars in bulk if you propose to develop more than one pack and save $)
o Wire: You'll want a better quality 12 gage which has a higher strand depend. This sort of wire, Using these properties will likely be a lot more adaptable which is ideal in addition to staying far more effective for energy transmission.
o eighty-100 Watt Soldering Gun. You'll be wanting a gun as you could be extra precise and more quickly - this is important as a result of heat sensitivity of batteries. The speedier and more certain you can be, the more unlikely you'll be to break the battery.
o 60/forty Solder. This is certainly bigger high quality - also important for fast and accurate operate and averting battery problems.
o Flux. It is a chemical cleansing agent that gets rid of oxidation from steel to facilitate soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive is going to be accustomed to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries adequately and aid a tidy Automated Guided Vehicles (AGV) Battery battery pack. The batteries end up basically searching like cord wood - tidily bundled.
o Soldering "Helping Arms" - optional. These products allow you to maintain items in position Whilst you solder.
o One more optional timesaver is to secure a "Aiding Arms" accessory for the soldering station.
o Multi Meter. You'll need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will assist you to handle, strip and appropriately Minimize your twelve gage wire.
o The ultimate part would be the shrink wrap that may go around the entire assembly and retain it tidy. You will also have to have a warmth gun to warmth and shrink the wrap.
So, you have identified how to orient your batteries and the number of you will need - now you receive to work on assembly. For this instance, we're assembling 12 battery cells - 6 down just one aspect and 6 down another.
When you finally identify exactly where the batteries are heading in relation to your chassis And just how they are going being laid out, you could get started. For this instance, to illustrate we're performing six down one particular aspect and six down another facet.
Just to make certain we are on the exact same webpage, the last word goal Here's to get managing wire with the beneficial terminal of your initially battery to your optimistic terminal on the electrical RC motor after which you can operating a wire with the unfavorable terminal on the last battery inside your pack towards the beneficial terminal of the other battery pack, therefore making a concluded circuit.
This mean you'll want to have adequate wire to succeed in from your good terminal within your to start with battery to that terminal and Similarly within the unfavorable to complete the circuit with all your other battery pack so bear that in your mind.
Orientation. Align your first cell to make sure that beneficial is pointing "upwards" and negative is pointing "downwards" then reverse another battery so it's reverse on down the line. If you purchased the battery assembly jig, this is if you'd use it to align your cells and maintain them set up.
Adhere. Adhere the many batteries together with your fast drying adhesive to They may be if you want and aligned effectively.
Flux. Make use of your flux now about the link details.
Link - Make use of your battery bars to connect your cells. You'll have to warmth up your soldering gun and heat up the battery bar. Using the bar protects the battery and when the flux begins to bubble, you make use of your utilization of solder. The goal is not to heat the battery itself. Heating the battery is don't just counterproductive, due to the fact in the event you problems the battery it is not going to perform, but additionally perilous since the mobile could possibly explode if overheated.
You'll be wanting to complete the exact same steps for the remaining battery connections. You happen to be connecting the detrimental on the constructive time and again once again. You may then be Completely ready to connect wiring to your battery pack.
The wires must be pre-tinned which mean you have to strip off a quarter inch in the protective plastic wiring sheath, make use of the flux to scrub them - use the flux liberally - heat your solder gun after which warmth the wire and movement the solder into the wire till thoroughly saturated. You may also want solder on the batteries Therefore the solder will act given that the connector While using the battery.
After the two, 6 mobile battery packs are entire, you'll want to employ the shrink wrap to safe them - and you'll have your full battery pack! Now you'll be able to electrical power and fly your RC helicopter, plane, boat, automobile or truck without having issues!
