Making an RC Battery Pack - A Essential How-To
If you love RC, you understand the necessity of a battery pack. The sort of batteries you decide on, how well your pack is assembled And exactly how effectively you charge them are all significant factors to powering your RC vehicle. Sure, You should buy a battery pack pre-assembled, but You can even Make your own private and have the pleasure of developing and powering your very own motor vehicle.
The very first thing you might want to do is when you decide To place collectively a battery pack is what you're powering and exactly how much juice you may need. You furthermore may have Automated Guided Vehicles (AGV) Battery to have to think about the following:
one. Think about the chassis of your vehicle. The sort of motor vehicle isn't going to issue up to the amount of Place by which You should maneuver. The batteries may well should be oriented inside a flat pack, a clustered pack or as both equally. It's also advisable to think of the distribution of excess weight inside your automobile - whether or not the battery body weight will probably be dispersed in the side to side or back again to entrance way. Sometimes your chassis House for any battery pack is just not adaptable, so know about All those constraints before you start.
two. Think about the motor powering your RC vehicle. Depending upon the electrical power specifications, you'll be able to ascertain what number of batteries or cells you would like. This is certainly also after you can choose the type of batteries you'll use - if you would like maintain your NiMH batteries or upgrade to LiPo.
3. Deciding your voltage is known as a simple make a difference of addition. A typical cell voltage is 1.2v, so wired inside of a sequence - 12 batteries will include as much as fourteen.4v - which would energy an fourteen.4 volt RC electric motor.
Following, You will need to collect your battery pack provides - so here's a sample procuring checklist. Don't forget, we are assuming we're making a battery pack with fourteen.4v, as in the instance higher than:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you are able to buy battery bars in bulk if you propose to develop multiple pack and help save $)
o Wire: You'll want a greater good quality twelve gage using a substantial strand count. Such a wire, with these attributes are going to be additional adaptable which is good together with being a lot more effective for ability transmission.
o eighty-one hundred Watt Soldering Gun. You will need a gun since you is usually much more precise and more quickly - this is necessary due to warmth sensitivity of batteries. The a lot quicker and even more particular you may be, the more unlikely you'll be to wreck the battery.
o sixty/40 Solder. This is certainly larger good quality - also important for brief and precise work and preventing battery damage.
o Flux. That is a chemical cleaning agent that removes oxidation from steel to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This fast drying adhesive will probably be utilized to bundle the batteries jointly.
o Battery Pack Assembly Jig - optional. These assembly gadgets align the batteries properly and aid a tidy battery pack. The batteries finish up basically hunting like wire wood - tidily bundled.
o Soldering "Aiding Hands" - optional. These devices let you hold points set up Whilst you solder.
o An additional optional timesaver is to get a "Serving to Palms" accessory for your soldering station.
o Multi Meter. You'll need a very good multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will assist you to deal with, strip and adequately cut your twelve gage wire.
o The final part will be the shrink wrap that will go across the overall assembly and preserve it tidy. You may also require a heat gun to heat and shrink the wrap.
So, you have discovered how to orient your batteries and the number of you need - now you receive to operate on assembly. For this example, we are assembling 12 battery cells - six down 1 aspect and 6 down the opposite.
When you discover in which the batteries are going in relation in your chassis And just how they are going to get laid out, you could start off. For this instance, as an instance we are undertaking six down a single side and 6 down one other aspect.
Just to be sure we are on the same website page, the last word purpose here is to be working wire through the optimistic terminal of your respective first battery on the optimistic terminal on the electrical RC motor and then managing a wire with the adverse terminal on the last battery in your pack to the constructive terminal of one's other battery pack, therefore creating a done circuit.
This mean you must have adequate wire to succeed in from your beneficial terminal of your initially battery to that terminal and Similarly within the adverse to accomplish the circuit along with your other battery pack so bear that in mind.
Orientation. Align your first cell in order that positive is pointing "upwards" and adverse is pointing "downwards" after which you can reverse the next battery so It is really opposite on down the road. If you bought the battery assembly jig, This can be whenever you'd use it to align your cells and maintain them in position.
Adhere. Stick the many batteries together with your quickly drying adhesive to They are really if you want and aligned correctly.
Flux. Make use of your flux now within the link factors.
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 in the event the flux starts to bubble, you employ your use of solder. The aim is not to heat the battery itself. Heating the battery is not simply counterproductive, because if you injury the battery it is not going to perform, and also unsafe as the mobile could possibly explode if overheated.
You'll want to complete the same ways for that remaining battery connections. You are connecting the unfavorable for the optimistic over and over yet again. You can then be Prepared to connect wiring in your battery pack.
The wires must be pre-tinned which indicate you have to strip off 1 / 4 inch of your protecting plastic wiring sheath, utilize the flux to wash them - use the flux liberally - heat your solder gun and after that warmth the wire and move the solder in to the wire until eventually totally saturated. You'll also want solder around the batteries so the solder will act given that the connector Along with the battery.
As soon as the two, six cell battery packs are entire, you'll want to use the shrink wrap to protected them - and you'll have your complete battery pack! Now you can electric power and fly your RC helicopter, plane, boat, vehicle or truck without having issues!
