Making an RC Battery Pack - A Primary How-To
If you're keen on RC, you understand the significance of a battery pack. The kind of batteries you end up picking, how nicely your pack is assembled And the way effectively you charge them are all important factors to powering your RC car or truck. Sure, you can buy a battery pack pre-assembled, but You can even Construct your own and acquire the gratification of planning and powering your very own car or truck.
The very first thing you must do is when you choose to put alongside one another a battery pack is what you're powering and the amount of juice you'll need. You also want to think about the subsequent:
1. Consider the chassis within your automobile. The sort of auto would not make a difference approximately the quantity of Place wherein You will need to maneuver. The batteries could should be oriented within a flat pack, a clustered pack or as each. It's also advisable to think of the distribution of excess weight inside your car - whether or not the battery body weight will likely be distributed within a facet to facet or again to entrance manner. Sometimes your chassis Area for your battery pack is not adaptable, so pay attention to People constraints Before you begin.
two. Consider the motor powering your RC vehicle. Based on the power prerequisites, you'll ascertain the amount of batteries or cells you require. This really is also when you can come to a decision the sort of batteries you can use - if you'd like Automated Guided Vehicles (AGV) Battery to keep your NiMH batteries or update to LiPo.
3. Deciding your voltage is known as a basic matter of addition. A normal cell voltage is one.2v, so wired in the series - 12 batteries will insert as many as fourteen.4v - which might ability an fourteen.four volt RC electric motor.
Future, You will need to assemble your battery pack supplies - so Here is a sample procuring list. Don't forget, we are assuming we're making a battery pack with fourteen.4v, as in the instance earlier mentioned:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you can get battery bars in bulk if you plan to develop multiple pack and help you save $)
o Wire: You'll be wanting a greater good quality twelve gage that has a superior strand rely. This kind of wire, Using these properties will probably be a lot more flexible which is right along with currently being extra successful for ability transmission.
o 80-one hundred Watt Soldering Gun. You'll be wanting a gun because you may be much more correct and faster - this is important as a result of warmth sensitivity of batteries. The more rapidly plus more distinct you can be, the less likely You will be to break the battery.
o sixty/40 Solder. This is higher top quality - also essential for rapid and precise perform and steering clear of battery hurt.
o Flux. This is the chemical cleaning agent that removes oxidation from steel to aid soldering. You can utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quick drying adhesive will probably be used to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries adequately and aid a tidy battery pack. The batteries turn out mainly on the lookout like twine wood - tidily bundled.
o Soldering "Encouraging Hands" - optional. These equipment help you keep matters in position When you solder.
o Another optional timesaver is to get a "Helping Arms" accent for your personal soldering station.
o Multi Meter. You'll need a fantastic multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These tools can assist you handle, strip and correctly cut your twelve gage wire.
o The ultimate part may be the shrink wrap that can go across the complete assembly and preserve it tidy. You are going to also require a heat gun to heat and shrink the wrap.
So, you have recognized the way to orient your batteries and how many you may need - now you receive to operate on assembly. For this example, we're assembling 12 battery cells - 6 down 1 aspect and 6 down another.
Once you detect where by the batteries are going in relation in your chassis and how they're going for being laid out, you can start. For this instance, for instance we're performing six down just one facet and six down another aspect.
Just to ensure we're on the exact same website page, the last word objective here is being jogging wire with the good terminal within your first battery into the optimistic terminal on the electric RC motor then running a wire with the unfavorable terminal on the final battery in the pack on the beneficial terminal of your other battery pack, thus making a concluded circuit.
This signify you have to have enough wire to achieve in the favourable terminal of your to start with battery to that terminal and likewise from your adverse to complete the circuit with all your other battery pack so bear that in mind.
Orientation. Align your initially cell to make sure that constructive is pointing "upwards" and negative is pointing "downwards" after which reverse another battery so It is opposite on down the road. If you purchased the battery assembly jig, this is after you'd use it to align your cells and maintain them set up.
Adhere. Stick every one of the batteries along with your quickly drying adhesive to They are really to be able and aligned properly.
Flux. Make use of your flux now about the connection details.
Link - Use your battery bars to connect your cells. You will need 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 use your usage of solder. The goal is not to warmth the battery itself. Heating the battery is don't just counterproductive, given that in the event you damage the battery it is not going to perform, but also perilous because the mobile may well explode if overheated.
You'll want to complete exactly the same actions with the remaining battery connections. That you are connecting the damaging on the favourable over and over all over again. You may then be All set to connect wiring for your battery pack.
The wires have to be pre-tinned which mean you need to strip off 1 / 4 inch on the protecting plastic wiring sheath, make use of the flux to clean them - apply the flux liberally - heat your solder gun after which heat the wire and movement the solder into the wire till completely saturated. You are going to also want solder over the batteries And so the solder will act because the connector While using the battery.
As soon as the two, 6 cell battery packs are finish, you'll be wanting to use the shrink wrap to protected them - and you'll have your complete battery pack! Now you'll electricity and fly your RC helicopter, aircraft, boat, automobile or truck with no problems!
