Setting up an RC Battery Pack - A Basic How-To
If you love RC, you already know the necessity of a battery pack. The type of batteries you choose, how perfectly your pack is assembled And just how competently you charge them are all vital factors to powering your RC vehicle. Confident, You should purchase a battery pack pre-assembled, but You can even Create your personal and obtain the satisfaction of planning and powering your own personal vehicle.
The first thing you might want to do is when you select to put together a battery pack is what you're powering and the amount of juice you need. You furthermore may need to consider the following:
1. Think about the chassis within your motor vehicle. The kind of car isn't going to subject just as much as the amount of space during which You will need to maneuver. The batteries may possibly should be oriented in a flat pack, a clustered pack or as each. It's also wise to take into consideration the distribution of bodyweight as part of your vehicle - if the battery pounds will probably be dispersed in a very facet to side or back to entrance method. Sometimes your chassis Room to get a battery pack is just not adaptable, so know about All those constraints before you start.
two. Look at the motor powering your RC car or truck. Based on the energy necessities, you'll be able to ascertain the amount of batteries or cells you would like. This can be also any time you can determine the sort of batteries you will use - if you wish to maintain your NiMH batteries or update Automated Guided Vehicles (AGV) Battery to LiPo.
three. Pinpointing your voltage can be a straightforward subject of addition. A regular mobile voltage is 1.2v, so wired in a very collection - 12 batteries will include around 14.4v - which might energy an fourteen.4 volt RC electric motor.
Upcoming, you'll need to gather your battery pack provides - so This is a sample purchasing record. Recall, we're assuming we are making a battery pack with 14.4v, as in the example higher than:
o 12 Batteries or Battery Cells
o twelve Battery Bars (you may get battery bars in bulk if you plan to create more than one pack and preserve $)
o Wire: You'll want a higher high quality twelve gage with a substantial strand count. This kind of wire, Using these characteristics are going to be much more versatile which is ideal together with currently being far more efficient for electric power transmission.
o eighty-one hundred Watt Soldering Gun. You'll be wanting a gun because you might be extra actual and faster - this is important due to heat sensitivity of batteries. The quicker plus much more unique you are able to be, the less likely You will be to damage the battery.
o 60/40 Solder. This can be increased high-quality - also significant for rapid and correct work and steering clear of battery problems.
o Flux. This is a chemical cleaning agent that eliminates oxidation from metal to aid soldering. You can utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will likely be used to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries appropriately and facilitate a tidy battery pack. The batteries turn out fundamentally hunting like wire wood - tidily bundled.
o Soldering "Assisting Fingers" - optional. These devices help you maintain issues set up Whilst you solder.
o Another optional timesaver is to acquire a "Serving to Palms" accessory for your personal soldering station.
o Multi Meter. You need a very good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These equipment will let you handle, strip and thoroughly Lower your 12 gage wire.
o The ultimate ingredient may be the shrink wrap that can go round the entire assembly and keep it tidy. You are going to also need a warmth gun to heat and shrink the wrap.
So, you've got identified the way to orient your batteries and the number of you require - now you receive to work on assembly. For this example, we're assembling 12 battery cells - six down one particular aspect and six down another.
As soon as you identify where by the batteries are likely in relation on your chassis And the way they're going to generally be laid out, you'll be able to start out. For this example, to illustrate we're performing 6 down 1 aspect and six down another side.
Just to make sure we are on exactly the same site, the last word target Here's to be functioning wire within the optimistic terminal within your 1st battery towards the constructive terminal on the electrical RC motor then managing a wire with the adverse terminal on the final battery in your pack to the good terminal of your respective other battery pack, therefore creating a completed circuit.
This imply you have to have adequate wire to achieve in the beneficial terminal of the 1st battery to that terminal and Furthermore from the negative to complete the circuit with the other battery pack so bear that in your mind.
Orientation. Align your first mobile to ensure positive is pointing "upwards" and negative is pointing "downwards" after which you can reverse another battery so It is reverse on down the road. If you purchased the battery assembly jig, That is whenever you'd utilize it to align your cells and keep them in place.
Adhere. Stick all of the batteries along with your rapidly drying adhesive to These are as a way and aligned appropriately.
Flux. Make use of your flux now to the relationship details.
Relationship - Use your battery bars to connect your cells. You will need to warmth up your soldering gun and warmth up the battery bar. Utilizing the bar protects the battery and once the flux begins to bubble, you utilize your use of solder. The objective is to NOT heat the battery by itself. Heating the battery is not just counterproductive, given that in case you injury the battery it is not going to get the job done, and also dangerous as the mobile may explode if overheated.
You'll want to finish the same techniques to the remaining battery connections. You're connecting the unfavorable into the positive again and again once again. You are going to then be All set to connect wiring towards your battery pack.
The wires have to be pre-tinned which imply you should strip off 1 / 4 inch from the protective plastic wiring sheath, utilize the flux to clean them - use the flux liberally - heat your solder gun and then heat the wire and flow the solder into the wire till completely saturated. You may also want solder around the batteries Hence the solder will act as being the connector Together with the battery.
After the two, 6 cell battery packs are entire, you will need to use the shrink wrap to protected them - and you'll have your finish battery pack! Now you'll be able to ability and fly your RC helicopter, plane, boat, car or truck or truck without any difficulties!
