Making an RC Battery Pack - A Simple How-To
If you like RC, you already know the importance of a battery pack. The kind of batteries you end up picking, how well your pack is assembled And just how proficiently you charge them are all critical facets to powering your RC motor vehicle. Confident, you can buy a battery pack pre-assembled, but You may also Make your individual and get the gratification of planning and powering your personal car.
The very first thing you need to do is when you select To place with each other a battery pack is what you're powering and just how much juice you may need. In addition, you will need to think about the following:
1. Consider the chassis of your respective vehicle. The kind of car won't make a difference up to the amount of Place wherein You should maneuver. The batteries may should be oriented in a flat pack, a clustered pack or as each. You should also contemplate the distribution of excess weight inside your car - whether the battery pounds will be distributed inside of a side to side or again to front fashion. In some instances your chassis Area for your battery pack is just not adaptable, so be aware of All those constraints before you start.
two. Think about the motor powering your RC auto. With regards to the electricity demands, you'll be able to establish how many batteries or cells you require. This is also whenever you can choose the sort of batteries you'll use - if you would like keep your NiMH batteries or up grade to LiPo.
three. Deciding your voltage is mostly a straightforward subject of addition. An ordinary mobile voltage is 1.2v, so wired in a very sequence - twelve batteries will include around 14.4v - which might energy an 14.4 volt RC electrical motor.
Following, You will need to collect your battery pack supplies - so Here is a sample browsing checklist. Keep in mind, we are assuming we are developing a battery pack with 14.4v, as in the example earlier mentioned:
o twelve Batteries or Battery Cells
o 12 Battery Bars (you can order battery bars in bulk if you plan to construct multiple pack and help save $)
o Wire: You'll want an increased good quality 12 gage that has a higher strand count. This sort of wire, with these features are going to be far more versatile which is ideal along with getting a lot more successful for energy transmission.
o eighty-100 Watt Soldering Gun. You'll be wanting a gun as you might be much more specific and a lot quicker - this is important due to the heat sensitivity of batteries. The a lot quicker and more certain you could be, the less likely You will be to wreck the battery.
o sixty/40 Solder. This is greater high-quality - also critical for quick and accurate get the job done and staying away from battery destruction.
o Flux. This is the chemical cleansing agent that eliminates oxidation from steel to aid soldering. You should use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive is going to be utilized to bundle the batteries together.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries properly and aid a tidy battery pack. The batteries wind up essentially looking like wire Wooden - tidily bundled.
o Soldering "Helping Palms" - optional. These equipment help you maintain matters in position while you solder.
o Yet another optional timesaver is to obtain a "Helping Arms" accessory to your soldering station.
o Multi Meter. You'll need a very good multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will allow you to deal with, strip and properly Reduce your 12 gage wire.
o The ultimate ingredient could be the shrink wrap that may go around the whole assembly and continue to keep it tidy. You can also require a heat gun to heat and shrink the wrap.
So, you have discovered ways to orient your batteries and how many you need - now you obtain to work on assembly. For this instance, we are assembling 12 battery cells - six down a person facet and 6 down the opposite.
When you recognize in which the batteries are heading in relation to the chassis And just how they're going to be laid out, you are able to start out. For this instance, let's say we are doing six down just one aspect and six down one other facet.
Just to be sure we are on the exact same website page, the final word objective here is for being working wire from the favourable terminal of your 1st battery for the favourable terminal on the electric RC motor and after that running a wire through the detrimental terminal on the final battery as part of your pack to your positive terminal of your other battery pack, thus making a concluded circuit.
This imply you have to have sufficient wire to reach within the optimistic terminal within your 1st battery to that terminal and Also within the destructive to finish the circuit along with your other battery pack so bear that in your mind.
Orientation. Align your 1st cell so Automated Guided Vehicles (AGV) Battery that favourable is pointing "upwards" and adverse is pointing "downwards" and then reverse the next battery so It is opposite on down the road. If you purchased the battery assembly jig, this is when you'd utilize it to align your cells and keep them set up.
Adhere. Stick many of the batteries along with your rapidly drying adhesive to They're in order and aligned thoroughly.
Flux. Make use of your flux now on the connection factors.
Connection - Make use of your battery bars to connect your cells. You'll need to heat up your soldering gun and heat up the battery bar. Using the bar protects the battery and once the flux begins to bubble, you use your use of solder. The aim is not to heat the battery alone. Heating the battery is not merely counterproductive, because for those who harm the battery it won't get the job done, but will also hazardous as the mobile could possibly explode if overheated.
You'll want to finish exactly the same methods with the remaining battery connections. You might be connecting the detrimental to your optimistic over and over once more. You can expect to then be All set to attach wiring towards your battery pack.
The wires have to be pre-tinned which necessarily mean you need to strip off 1 / 4 inch in the protecting plastic wiring sheath, use the flux to wash them - use the flux liberally - heat your solder gun and after that warmth the wire and circulation the solder to the wire right until comprehensively saturated. You will also want solder within the batteries Therefore the solder will act given that the connector Together with the battery.
Once the two, six cell battery packs are finish, you will need to hire the shrink wrap to safe them - and you will have your total battery pack! Now you'll be able to power and fly your RC helicopter, aircraft, boat, vehicle or truck without any complications!
