Making an RC Battery Pack - A Simple How-To
If you like RC, you already know the necessity of a battery pack. The type of batteries you decide on, how well your pack is assembled And the way competently you cost them are all important factors to powering your RC car. Certain, You should purchase a battery pack pre-assembled, but You may as well Establish your own personal and acquire the fulfillment of coming up with and powering your very own automobile.
The very first thing you might want to do is when you choose to put jointly a battery pack is what you're powering and the amount of juice you would like. You furthermore mght need to have to consider the subsequent:
1. Look at the chassis within your motor vehicle. The kind of car or truck isn't going to issue about the level of Place in which you have to maneuver. The batteries may possibly must be oriented in the flat pack, a clustered pack or as each. It's also wise to think of the distribution of weight as part of your car - whether or not the battery pounds will probably be distributed within a aspect to aspect or back again to front manner. In some cases your chassis Area for the battery pack is just not adaptable, so be aware of Those people constraints before you start.
two. Look at the motor powering your RC vehicle. According to the ability specifications, you can determine the quantity of batteries or cells you'll need. This is often also any time you can come to a decision the sort of batteries you can expect to use - if you wish to keep the NiMH batteries or improve to LiPo.
three. Analyzing your voltage is mostly a straightforward make any difference of addition. A standard cell voltage is 1.2v, so wired in the collection - twelve batteries will increase nearly fourteen.4v - which would electric power an 14.four volt RC electric powered motor.
Upcoming, You'll have to assemble your battery pack supplies - so here's a sample purchasing checklist. Bear in mind, we are assuming we are creating a battery pack with 14.4v, as in the example earlier mentioned:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you can order battery bars in bulk if you plan to create multiple pack and save $)
o Wire: You'll be wanting an increased top quality 12 gage which has a higher strand rely. This kind of wire, with these properties will be far more flexible which is good in addition to currently being additional economical for electrical power transmission.
o eighty-one hundred Watt Soldering Gun. You will need a gun since you might be additional precise and a lot quicker - this is critical because of the warmth sensitivity of batteries. Automated Guided Vehicles (AGV) Battery The a lot quicker and even more precise it is possible to be, the more unlikely you'll be to wreck the battery.
o sixty/40 Solder. This is bigger top quality - also critical for quick and correct perform and steering clear of battery destruction.
o Flux. This is the chemical cleansing agent that eliminates oxidation from metal to facilitate soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This rapid drying adhesive is going to be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries appropriately and aid a tidy battery pack. The batteries end up essentially searching like cord Wooden - tidily bundled.
o Soldering "Serving to Palms" - optional. These equipment permit you to maintain matters in position while you solder.
o A different optional timesaver is to secure a "Helping Fingers" accessory for the soldering station.
o Multi Meter. You will need a very good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will allow you to take care of, strip and correctly Minimize your twelve gage wire.
o The ultimate ingredient is definitely the shrink wrap that will go within the complete assembly and continue to keep it tidy. You will also require a heat gun to warmth and shrink the wrap.
So, you've got determined how to orient your batteries and what number of you would like - now you will get to operate on assembly. For this instance, we're assembling twelve battery cells - six down a person aspect and 6 down the opposite.
When you recognize the place the batteries are likely in relation in your chassis And just how they are going to generally be laid out, you could commence. For this instance, as an instance we are executing six down one particular facet and 6 down one other aspect.
Just to ensure we're on the same site, the final word intention here is to be jogging wire from your favourable terminal of one's to start with battery to the good terminal on the electrical RC motor then working a wire with the destructive terminal on the final battery as part of your pack towards the good terminal of one's other battery pack, thus creating a completed circuit.
This indicate you have to have enough wire to achieve with the beneficial terminal of the initially battery to that terminal and Similarly within the negative to finish the circuit together with your other battery pack so bear that in your mind.
Orientation. Align your first mobile in order that good is pointing "upwards" and adverse is pointing "downwards" after which reverse the subsequent battery so It is reverse on down the line. If you bought the battery assembly jig, This is often after you'd use it to align your cells and hold them set up.
Adhere. Adhere many of the batteries along with your fast drying adhesive to They can be to be able and aligned adequately.
Flux. Use your flux now about the connection factors.
Link - Use your battery bars to attach your cells. You'll need to heat up your soldering gun and warmth up the battery bar. Utilizing the bar shields the battery and if the flux begins to bubble, you hire your use of solder. The target is not to heat the battery itself. Heating the battery is not just counterproductive, since for those who destruction the battery it will not operate, and also hazardous because the mobile might explode if overheated.
You'll be wanting to finish a similar steps for that remaining battery connections. You happen to be connecting the destructive towards the positive over and over again. You are going to then be ready to connect wiring on your battery pack.
The wires must be pre-tinned which necessarily mean you must strip off 1 / 4 inch of your protecting plastic wiring sheath, use the flux to clean them - use the flux liberally - heat your solder gun and afterwards heat the wire and circulation the solder in the wire right up until extensively saturated. You'll also want solder around the batteries Hence the solder will act because the connector with the battery.
As soon as the two, 6 cell battery packs are finish, you will need to use the shrink wrap to secure them - and you'll have your complete battery pack! Now you'll electric power and fly your RC helicopter, airplane, boat, automobile or truck with no challenges!
