Setting up an RC Battery Pack - A Essential How-To
If you like RC, you understand the value of a battery pack. The type of batteries you choose, how very well your pack is assembled And the way competently you demand them are all crucial elements to powering your RC car or truck. Sure, you can buy a battery pack pre-assembled, but you can also Create your own personal and obtain the fulfillment of developing and powering your own automobile.
The very first thing you might want to do is when you decide to put jointly a battery pack is what you're powering and how much juice you require. You also need to have to consider the subsequent:
one. Think about the chassis of your respective motor vehicle. The kind of vehicle doesn't make a difference up to the quantity of space through which You will need to maneuver. The batteries may well must be oriented inside of a flat pack, a clustered pack or as the two. It's also wise to give thought to the distribution of bodyweight as part of your vehicle - whether or not the battery body weight is going to be dispersed in a aspect to facet or back to front way. Occasionally your chassis Area for the battery pack isn't adaptable, so be familiar with Those people constraints before you start.
2. Consider the motor powering your RC auto. Dependant upon the power prerequisites, you can establish the quantity of batteries or cells you'll need. This really is also once you can determine the sort of batteries you are going to use - if you want to maintain your NiMH batteries or upgrade to LiPo.
three. Deciding your voltage can be a very simple issue of addition. A typical mobile voltage is 1.2v, so wired in the collection - 12 batteries will include around fourteen.4v - which might electrical power an fourteen.4 volt RC electric powered motor.
Up coming, You'll have to assemble your battery pack provides - so Here is a sample shopping checklist. Don't forget, we are assuming we're developing a battery pack with 14.4v, as in the example above:
o 12 Batteries or Battery Cells
o 12 Battery Bars (you'll be able to get battery bars in bulk if you intend to build multiple pack and conserve $)
o Wire: You will need a greater excellent 12 gage by using a superior strand rely. Such a wire, Using these traits will likely be more flexible which is ideal as well as remaining extra economical for power transmission.
o eighty-a hundred Watt Soldering Gun. You'll want a gun simply because you may be extra exact and faster - this is essential because of the heat sensitivity of batteries. The faster plus more certain you can be, the not as likely You will be to wreck the battery.
o 60/forty Solder. This can be greater high-quality - also essential for speedy and accurate work and avoiding battery destruction.
o Flux. This is the chemical cleaning agent that removes oxidation from steel to aid soldering. You should utilize liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This quickly drying adhesive are going to be utilized to bundle the batteries collectively.
o Battery Pack Assembly Jig - optional. These assembly units align the batteries effectively and aid a tidy battery pack. The batteries find yourself in essence searching like cord wood - tidily bundled.
o Soldering "Serving to Arms" - optional. These gadgets enable you to hold matters in place When you solder.
o Yet another optional timesaver is to secure a "Serving to Arms" accessory in your soldering station.
o Multi Meter. You need a excellent multimeter to check voltage and polarity.
o Wire strippers and Wire Cutters. These instruments will allow you to take care of, strip and properly Minimize your twelve gage wire.
o The final part may be the shrink wrap that can go around the full assembly and retain it tidy. You will also have to have a warmth gun to warmth and shrink the wrap.
So, you have identified the way to orient your batteries and the amount of you'll need - now you receive to work on assembly. For this example, we're assembling 12 battery cells - 6 down a person side and six down another.
When you discover where by the batteries are likely in relation to the chassis And the way they are going to become laid out, you'll be able to start off. For this instance, for instance we're executing six down just one facet and 6 down the opposite aspect.
Just to be certain we are on the identical webpage, the ultimate objective Here's to become operating wire within the favourable terminal of one's to start with battery to your constructive terminal on the electric RC motor and after that running a wire from the unfavorable terminal on the last battery in your pack towards the beneficial terminal of your respective other battery pack, thus creating a accomplished circuit.
This indicate you must have adequate wire to succeed in from your good terminal of your respective very first battery to that terminal and likewise from your detrimental to Automated Guided Vehicles (AGV) Battery complete the circuit using your other battery pack so bear that in your mind.
Orientation. Align your to start with cell to make sure that optimistic is pointing "upwards" and damaging is pointing "downwards" after which reverse the next battery so It truly is reverse on down the road. If you purchased the battery assembly jig, This can be whenever you'd utilize it to align your cells and keep them set up.
Adhere. Adhere all of the batteries together with your quick drying adhesive to These are as a way and aligned appropriately.
Flux. Use your flux now to the link points.
Connection - Use your battery bars to attach your cells. You'll need to warmth up your soldering gun and warmth up the battery bar. Using the bar protects the battery and if the flux begins to bubble, you use your utilization of solder. The intention is to NOT heat the battery itself. Heating the battery is not merely counterproductive, due to the fact for those who destruction the battery it will never get the job done, but in addition risky since the cell may explode if overheated.
You'll want to complete a similar ways for that remaining battery connections. You will be connecting the unfavorable into the optimistic repeatedly once again. You will then be Completely ready to connect wiring to the battery pack.
The wires should be pre-tinned which mean you must strip off 1 / 4 inch of the protective plastic wiring sheath, make use of the flux to wash them - utilize the flux liberally - heat your solder gun and afterwards warmth the wire and movement the solder to the wire right up until thoroughly saturated. You can also want solder about the batteries Therefore the solder will act given that the connector While using the battery.
As soon as the two, 6 mobile battery packs are entire, you'll be wanting to use the shrink wrap to safe them - and you'll have your complete battery pack! Now you can power and fly your RC helicopter, airplane, boat, vehicle or truck without difficulties!
