Developing an RC Battery Pack - A Simple How-To
If you love RC, you understand the value of a battery pack. The sort of batteries you choose, how nicely your pack is assembled and how successfully you cost them are all important factors to powering your RC car or truck. Confident, You should purchase a battery pack pre-assembled, but It's also possible to build your individual and have the satisfaction of planning and powering your own car or truck.
The first thing you should do is when you choose to put collectively a battery pack is what you are powering and the amount juice you need. You furthermore mght will need to consider the subsequent:
1. Look at the chassis of your respective vehicle. The sort of auto isn't going to matter as much as the quantity of Place during which You must maneuver. The batteries may well must be oriented inside of a flat pack, a clustered pack or as equally. It's also wise to think of the distribution of body weight within your motor vehicle - whether the battery excess weight will be dispersed in a very aspect to facet or back again to front fashion. Occasionally your chassis Place for the battery pack is just not adaptable, so concentrate on People constraints before you start.
2. Look at the motor powering your RC vehicle. With regards to the power necessities, you'll be able to identify what number of batteries or cells you require. This is certainly also if you can decide the type of batteries you'll use - if you'd like to keep the NiMH batteries or upgrade to LiPo.
three. Analyzing your voltage is really a simple make any difference of addition. A standard mobile voltage is 1.2v, so wired in a very sequence - twelve batteries will include up to fourteen.4v - which would electric power an 14.four volt RC electric motor.
Next, You'll have to collect your battery pack supplies - so This is a sample shopping record. Remember, we are assuming we're developing a battery pack with fourteen.4v, as in the example earlier mentioned:
o twelve Batteries or Battery Cells
o twelve Battery Bars (you may get battery bars in bulk if you plan to construct multiple pack and help save $)
o Wire: You will need a higher excellent 12 gage by using a significant strand count. This kind of wire, with these properties will likely be much more adaptable which is ideal as well as staying a lot more economical for power transmission.
o eighty-a hundred Watt Soldering Gun. You will need a gun as you is often far more actual and a lot quicker - this is essential because of the warmth sensitivity of batteries. The faster and a lot more certain you are able to be, the less likely you'll be to break the battery.
o 60/forty Solder. This is bigger top quality - also vital for speedy and correct work and avoiding battery hurt.
o Flux. That is a chemical cleaning agent that eliminates oxidation from metal to facilitate soldering. You may use liquid or paste flux when assembling a battery pack.
o Shoo Goo or Goop. This speedy drying adhesive will probably be used to bundle the batteries alongside one another.
o Battery Pack Assembly Jig - optional. These assembly products align the batteries properly and facilitate a tidy battery pack. The batteries wind up essentially hunting like wire Wooden - tidily bundled.
o Soldering "Serving to Fingers" - optional. These devices assist you to hold matters in position As you solder.
o Another optional timesaver is to acquire a "Serving to Hands" accessory on your soldering station.
o Multi Meter. You'll need a superior multimeter to test voltage and polarity.
o Wire strippers and Wire Cutters. These tools will help you cope with, strip and correctly Lower your 12 gage wire.
o The ultimate component may be the shrink wrap that may go throughout the overall assembly and retain it tidy. You'll also need a warmth gun to warmth and shrink the wrap.
So, you've determined the best way to orient your batteries and the quantity of you would like - now you obtain to operate on assembly. For this example, we are assembling 12 battery cells - 6 down one aspect and 6 down the opposite.
After you identify exactly where the batteries are heading in relation to your chassis And the way they are going to generally be laid out, you are able to start off. For this instance, for instance we are performing 6 down a single aspect and 6 down one other side.
Just to be certain we're on the identical web page, the last word intention here is to get running wire from your positive terminal within your very first battery into the good terminal on the electrical RC motor after which you can functioning a wire within the negative terminal on the final battery as part of your pack towards the positive terminal of your other battery pack, therefore developing a done circuit.
This indicate you might want to have ample wire to succeed in within the favourable terminal of your respective to start with battery to that terminal and Also from the negative to complete the circuit along with your other battery pack so bear that in your mind.
Orientation. Align your to start with mobile making sure that favourable is pointing "upwards" and detrimental is pointing "downwards" after which you can reverse another battery so It can be reverse on down the road. If you purchased the battery assembly jig, That is once you'd use it to align your cells and hold them in place.
Adhere. Stick many of the batteries together with your fast drying adhesive to They are really in order and aligned appropriately.
Flux. Use your flux now on the link points.
Link - Make use of your battery bars to attach your cells. You'll have to warmth up your soldering gun and warmth up the battery bar. Using the bar guards the battery and if the flux starts to bubble, you employ your usage of solder. The goal is not to warmth the battery itself. Heating the battery is not only counterproductive, considering that in the event you hurt the battery it would not get the job done, but additionally risky because the cell may explode if overheated.
You will need to accomplish exactly the same measures with the remaining battery connections. You are connecting the detrimental on the favourable repeatedly all over again. You may then be Completely ready to connect wiring to your battery pack.
The wires must be pre-tinned which necessarily mean you Automated Guided Vehicles (AGV) Battery need to strip off a quarter inch of your protective plastic wiring sheath, use the flux to scrub them - use the flux liberally - warmth your solder gun after which you can warmth the wire and circulation the solder in the wire until finally comprehensively saturated. You can also want solder about the batteries Therefore the solder will act because the connector Using the battery.
After the two, 6 cell battery packs are finish, you'll be wanting to use the shrink wrap to protected them - and you will have your full battery pack! Now you'll energy and fly your RC helicopter, plane, boat, auto or truck with no difficulties!
